NOTE LI. MECOPTERA AND PLANIPENNIA OF INSULINDE

BY

Dr. H. W. VAN DER WEELE,

WITH BIOLOGICAL NOTES FBOM

EDW. JACOBSON.

Before my departure to Java I intended to give a mono- graphic revision of the Neuropteroidea of Insulinde, but want of time and of sufficient materials forced me to give up this intention and I restricted it to the monographic revision of the Mrcoprera and PrLANIPENNIA, the two orders I studied with special attention since 3 years in béhalf of the „Catalogue des collections du baron K, de Sélys Longchamps”.

The territories that 1 name Insulinde are the Dutch colonies of the malayan and papuan archipelago. I describe also the species known from those parts of Borneo and New Guinea, that do not belong to the dutch possessions, as they very probably also will occur in them. Those of neigh- bouring countries are noted so far as they are important for comparison.

The materials studied are those of the Leyden Museum and some types of Gerstaecker from the Greifswald Museum, which Prof. G. W. Miiller generously communicated to me and that facilitated this work very much. My best thanks for this courtesy, that enabled me to decide many questions about the systematic position of little known species. I had no time to work out materials of other museums, though I

am acquainted with many fine new species from this terri- tory. Only the described species that I saw in those Mu- seums are here redescribed, though they are not represented in Leyden.

I am endebted for many interesting biological notes to my friend Edw. Jacobson in Batavia, whose accurate ob- servations are very valuable contributions to the biology of these so neglected orders of insects. In future 1 hope to collaborate with him in the same agreeable way.

Though of little economic value the larvae of some species of Chrysopa and Micromus are observed by Dr. L. Zehntner to be useful by the destruction of Aphidae and Coccidae.

No doubt many species and genera will still be detected in these orders to which so little attention has been paid. Their biology also will surely give opportunity to many interesting discoveries.

Key to the orders.

The imagines are slender mediocre insects, with four equal, narrow wings, that have many furcated longitudinal veins, which scarcely are connected by some crossveins. In rest the wings are held horizontally, the forewings cover than the hindwings. The mouthparts are produced into a long beak, at the tip of which the short mandibles are inserted. Antennae very long and threadlike, nearly as long as the wings. Legs very long and slender, longer than the body. Body slender.

The larvae live, so far as is known, in the earth; they are carnivorous, with biting mandibles, and they pupate in the ground without cocon. Pupa libera.

Mecoprera (PANORPATA). Scorpionflies.

Imagines from moderately large to minute insects, with four nearly equal wings with a dense reticulated nervature, which are held rooflike in the rest. Mouthparts never forming a

beak, only somewhat produced. Antennae varying from short clubs to long setae. Legs much shorter and thicker, shorter than the body. Body shorter or longer than the wings,

Larvae living on land, seldom in water, carnivorous, with long pierced mandibles with which they suck out their prey, consisting in other insects. Cocon always spherical, spun on leaves or in the ground, Pupa libera.

PLANIPENNIA.

PART I,

MEcoprTERA. (With 1 plate and 8 text-figures).

These curious insects are hitherto only known from Java and Sumatra, and all species belong to the genera Panorpa and Zeptopanorpa, which are characteristic by the long abdominal segments of the male, the last one being produced into a cheliferous segment. No doubt the asian and australian genus Bittacus and the australian genus Chorista will also be found in some parts. So far as is known the species I enu- merate here are collected in mountainous regions, Nothing is known about their biology and development.

Key to the genera.

are known, different by the curious process of the hindborder of the third tergit, which bears a very variable clubshaped prominency, that rests upon an elevation of the fourth tergit and which does not exist in the european species. I would propose for this group, that overleads to Leptopanorpa, the subgeneric name of Neopanorpa. The females are not dif- ferent from those of european species.

The colours of the wings are like those of the european species, or they are less developed and may also wholly disappear. In the latter case the males have a long and slender abdomen and are only distinct from Leptopanorpa by the sessile ninth or cheliferous segment. In all species the subcosta joins the costa at the pterostigma in the forewings and in the hindwings about in the middle.

Key to the species.

Wings narrow, hyaline with black pattern. A broad pterostigmatical band reaches the hindborder in both wings and is connected along the foreborder with a quadrangular large apical spot, that has in the fore- wing an oblique distal prominency. In the forewings there is a small turned t-shaped spot in the middle, which does not touch the borders. 4

Panorpa javanica Westwood.

Panorpa javanica Westwood, Transact. Ent. Soc. Lond. (2) I, p. 5 (1852). Java.

This species is nearly related to angustipennis Westw. and of the same size. The differences are: a broad black erossband before the middle of the wing, a black point at the anterior border in the middle, a very broad sr-shaped pterostigmatical patch, which is connected at the anterior border with the broad apical patch. The latter is bordered towards the base by a straight line.

The abdomen of the male is very long and slender.

Habitat: Java and Sumatra.

In the British Museum I saw in 1906 specimens from both islands.

Panorpa miilleri, n. sp.

Very similar and nearly related to P. angustipennis Westw., but differing from it in the following points:

The pterostigmatical fascia about half so narrow. The apical spot is considerably smaller and only narrowly con- nected with the pterostigma along the foreborder. In the hindwing it is nearly wholly separated from it. The distal prominency of it in angustipennis is only indicated by a right angle. The rest of the wing is hyaline.

Body, legs etc. as in angustipennis.

The gonopoda of the ©’ differ in the following points:

Genus Leptopanorpa Mac Lachlan (1875). Transact. Ent, Soc. Lond. 1875, p. 187 (1875).

This genus is merely based upon the characters of the cj’ and is characterised by the slenderness of all parts. The body is very long, the basal segments of the abdomen are long, the 3 terminal ones very long and thread-like, the cheliferous segment is elongate-pedunculate. The wings are very narrow and the rostrum and legs are exceedingly long.

An approach and rather a transition to this genus form species as P. nematogaster and jacobsoni, but the ninth segment is here sessile or shortly pedunculate.

The typical species ritsemae and sieboldi occur in Japan, and in Insulinde this genus in represented by the following new species: |

In the Leyden Museum is a female of a Panorpa from Java, named by Dr. S. C. Snellen van Vollenhoven P. charpentieri, which agrees very well with Burmeister’s description; but as I have not seen the types, the description being very short and the locality the very general indication »Ost-Indien”’, so I doubt it is the real charpentieri.

There are in the Leyden Museum also fragments of another undescribed species from Java collected by S. Müller. No doubt the number of species, known from Insulinde, will considerably increase in future,

This family, to which the largest Planipennia belong, remembers by the colour and form of the wings much the Odonata and by the long clubbed antennae the Rhopalocera. As I have recently described it thoroughly in the » Catalogue des collections zoologiques du baron EH. de Sélys Long- champs”, 1 refer to this work for the species of Insulinde.

The biology and development are unknown of nearly all species and many new forms are surely to be detected.

Myrmeleonidae.

The Myrmeleonidae or Ant-lions are familiar to every entomologist by the curious habits of the larva which, living in dry earth or sand, goes backwards and makes often pitt- falls to prey insects.

The imagines are nocturn, also prey on insects as nearly all other Planipennia and are characterised by the short, mostly broadly clubbed antennae, the elongate densely reti- culated wings, which have the apicalfield with many rows of oblique cells. The postcosta of the wings, the length and form of the antennae, the legs and comparative length and form of the spurs are of most systematical value. The pattern of the head and pronotum are of much value to distinguish the species and their subspecies.

Antennae very short, with a broad club; black, the basal third rufous,

Head moderately broad, orange, a broad shining black line above the antennae and a ditto spot between the an- tennae connected with it. Vertex unicolorous, Prothorax much broader than long, with three black points which are often connected to a black transverse band. Meso- and metathorax of the same colour, each with a shining black spot on the scutellum. Breast of the same colour as the dorsum, with black spots and lines between the coxae. Legs rather short and strong, the femora yellow with an exterior black line, the tibiae black, excepted the base which is yellow, tarsi black. Spurs black, strongly curved, as long as the first tarsal joint. Claws long, black. Abdomen of the © a little shorter than the hindwing, that of the female shorter, yellow, the tergits with black broad lateral stripes, the third tergit in the male nearly black with dense erected brown hairs. Venter yellow with a dark longitudinal stripe in the middle. The male with two slightly curved, yellow app. sup. which are about as long as the penultimate segment.

Wings moderately long and broad, similar in shape, cream to yellowish white with white nervature. The forewings with mtany very irregular, more or less connected, narrow, black transverse lines and in the costalfield are blotches of the same colour. In the hindwing there is only a dark spot in the middle and some stripes at the apex. The pattern is very variable. The pterostigma is white in both wings. The male has a small sepiabrown pelotte.

it under the-name compositus from North India and North Bengal. I saw in the British Museum a specimen collected by Dr. Horsfield in Java. |

Probably this is still a different subspecies of the con- tinental form, but as the species also occurs nearly un- differentiated in Africa (clavicornis Latr.) it is better to decide this question with more material.

Echthromyrmex orientalis Mac Lachlan. Mac Lachlan, Ann. Soc. Ent. Belg. XVI, p. 143 (1873). Moluccas.

I saw the type in the collection de Sélys in Brussels and no doubt the mentioned locality is wrong, as there is in the same collection a quite similar specimen from Burmah. As the other species of this genus, E. platypterus Me. Lachl., is from Bagdad and as I saw an undescribed species from Ceylon in the British Museum, I presume that it does not extend so far as Insulinde.

Genus Formicaleo Leach (1815). Leach, Edinburg Encycl. IX, p. 138 (1815).

This genus has the tarsi analogous with Zomatares, but the spurs are much longer (as long as the four basal joints); the last joint is much longer. The antennae are longer than head and thorax together and clubbed at the apex. The wings are hyaline, spotted with some dark atoms, and about equal in length, long and narrow. Gonopoda of the o' short and the app. sup. valvular.

This genus occurs in all parts of the world. In Insulinde it is represented by the following widely spread species:

Formicaleo audax (Walker). (Plate 2, fig. 6).

OF INSULINDE, 21

Legs short and stout, luteous to brown, with white hairs and black spines. Femora brown above, luteous beneath. Coxae luteous. Tibiae luteous beneath, densely spotted with black above. Tarsi black, the articulations and the base of the basal and apical joint red. Claws very strong, red, black at the tip. Spurs curved, black at the tip, as long as the first four tarsal joints.

Abdomen long and stout, shorter than the wings. Dorsum brown with four luteous markings, viz.: a quadrangular one at the frontborder, almost connected with a triangular one at the hind border, which occupies more than one half of the segment, and two lateral round ones about at the middle. In the posterior segments they are connected to a luteous cross, but often the abdomen shows no light markings by decomposition of the entrails, Venter luteous with a broad darker median line.

Gonopoda very short and inconspicuous, the male with a very small triangular genitalvalve and short valvular app. sup.

. Wings elongate and narrow with acute tips, the posterior as long as, but narrower than the anterior ones. Nervature not very dense, all veins spotted with white, the longitu- dinal veins show this very clear, especially the subcosta and radius. Costalveins simple, only some of them before the pterostigma are forked. Pterostigma whitish, oval, small, with a dark spot at the junction of radius and subcosta, which spot is larger in the forewings and much more distinct. Apical part with pale oblique lines where the veins are white and with broadly brown suffused gradate veins, forming 2, 3 or more rows in the forewings, in the hindwings they are much less distinct and often absent. The posteosta and ramus obliquus of the forewings are distinctly united and at their junction often a brown spot is to be seen that is very large in some individuals. In the hindwings the ramus obliquus is very short and the subcosta does not reach it; there is no dark spot at this place. A pelotte is not developed.

The dimensions of the species vary much, also the colours of wings and body depending from the state of maturity.

22 MECOPTERA AND PLANIPENNIA

Body 27—35 mm., forow. 31—38 mm., hindw. 31—38 mm., ant. 7—11 mm. abd. 20—25 mm., gr. br. 6—8 mm. gr. br, 5—7 mm.

Habitat: India, Ceylon, China, Japan, Insulinde, Australia, van Diemensland and New Zealand.

This species is so extremely variable, that I believe it impossible to distinguish subspecies with certainty. All variations occur in the different localities from which I saw materials.

After the localities the following subspecies are probably to be distinguished:

Formicaleo audax audax (Walker).

This is synonymous with lentus Wlk. and the form of Continental India.

Formicaleo audax gravis (Walker).

Synonymous with dirus Wlk. and the form of Ceylon.

Formicaleo audax vafer (Walker).

Synonymous with desperatus W1k. and the form of Aus- tralia. Probably perniciosus Wlk. and insomnis WlIk., of which no fatherland is known, belong also to this form.

Formicaleo audax malefidus (Walker). This is the form of van Diemensland, the specimens from New Holland belong to vafer Wlk. Formicaleo audax acutus (Walker). Is the more aberrant form of New Zealand. Formicaleo audax morpheus Kirby.

Can probably be separated as the form of Christmas Island, south from Java.

I examined a pretty series from Insulinde from the following. localities :

Banka, two females collected by Teysman and Budding.

Java, one specimen collected by S. Müller, one male collected by Mr. M. C. Piepers, one male from Ambarawa, Central Java, collected by Ludeking and one small male collected in Semarang by Edw. Jacobson.
