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 Notes from the Leyden Museum, Vol. XX XI. IE 2 MECOPTERA AND PLANIPENNIA 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 Notes from the Leyden Museum, Vol. XXXI. OF INSULINDE. 3) 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. _ Abdomen of the © as long as the wings or somewhat longer, cheliferous segment sessile or very shortly pedunculate. Panorpa Linné. - Abdomen of the <7 much longer, about twice, than the wings, cheliferous segment longly pedunculate. Leptopanorpa Me. Lachl. Genus Panorpa Linné (1758). The malayan species of this genus are, so far the males Notes from the Leyden Museum, Vol. X XXI. 4 MECOPTERA AND PLANIPENNIA 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.

Zhe striped sides of head and throat and with the dull red fore neck was shot 21 August 1909 at Nieuwkoop. This species surely breeds on the lakes near Leyden. Podiceps auritus (L.). We received five specimens in winter dress; one, shot 2 November 1908 at Zoeterwoude near Leyden, and four, shot 4 and 26 February and 16 March 1909 near Texel. Podiceps nigricollis Brehm. Of this species, which in my former contributions I could not mention as being received by our Museum du- ring the last years, I purchased this winter three examples, all in winter dress, viz.: «/, 1 December 1908 near Texel; Q, 5 January 1909 near Texel and Q, 25 February 1909 near Texel. Colymbus arcticus L. Two specimens in winter dress are received: f, shot 27 January 1909 near den Helder and Q of very small size, wing only 260 mm., 26 February 1909 near den Helder. Sula bassanus (L.). In my former list I could mention only adult examples of this species. Last year we received two young birds, op and Q, shot 4 and 5 November 1908 near Texel and an adult 6, found dead on the shore near Cocksdorp, Texel. Botaurus stellaris (L.). We received a female, that has been killed 21 January 1909 at Beek near Breda. In winter this species occurs rarely. Phoenicopterus roseus Pallas. A second example of this Flamingo has been shot in our country about at the same spot where the first specimen has been killed. The bird was swimming in sea off the Notes from the Leyden Museum, Vol. Xx XXI. 214 ON BIRDS FROM THE NETHERLANDS. coast of Friesland near Cornwerd and was shot on 15 November 1908 by a fisherman, who thought it was a swan. It is an adult male in most perfect plumage. Whether we have to do here with a bird escaped from captivity or with a wild bird, can not be said with certainty; both possi- billities are equally probable. Cygnus bewickit Yarrell. We purchased two adult specimens, © and 9, which have been shot in the middle of March 1909 on the Zui- derzee near Kampen. Branta bernicla glaucogaster (Brehm). According to Sir R. Payne-Gallwey, one may shoot an entire winter on the shores of North-Holland, without being able to kill, or even to see, a brent with a white abdomen (Alphéraky, the Geese of Europe and Asia, 1905, p. 161). It is a fact, that the light-bellied brent is a rare visitant to our shore, but that it is not to be found here, is a mistake. As I have shown in my list of the birds of the Netherlands, there are three examples in our old col- — lection and this year I received two other examples, a female, shot 4 February 1909 on Texel and a female, shot 17 February at Noordwijk aan Zee. All the specimens of this form in our possession are females. Aythia nyroca (Güldenstädt). The series of this species has been enlarged with four examples from our country, viz.: Q, shot 10 November 1908 at ter Aar, province Zuid-Holland, two oo’, both in nuptial dress, shot 13 March 1909 at Leimuiden, and oO in change, shot 19 July 1909 at Nieuwkoop. In one of the males shot 18 March there is a large white spot on the chin, whereas in the other one there are only a few white feathers on the chin. Fuligula fuligula (L.). Of Fuligula fuligula I received in the last months some Notes from the Leyden Museum, Vol. XXXI. ON BIRDS FROM THE NETHERLANDS. 215 specimens in interesting stages of plumage, that were totally unknown to me and that were not represented in the series of this species in our general collection. These specimens necessitate me to revert to the example, which [ mentioned last year as being a hybrid between Fuligula fuligula (L.) and Aythia nyroca (Güldenstädt) (Notes Leyden Museum, XXX, 1908—’09, p. 150, pl. 7) but which I consider now as an adult female of Fuligula fuligula changing from the summer plumage into the winter plumage. This year I received two females, shot 26 July (plate 6, fig. b) and 12 August 1909 (plate 6, fig. a) at Nieuw- koop, in which the whole undersurface is dark brown, the feathers being edged with pale brown or with whitish. A few pure white feathers are to be observed between the brown feathers, when lifting up these. In a female shot 24 Au- gust 1909 (plate 6, fig. c) at Nieuwkoop, the feathers of the undersurface are dark brown, those of the middle of the breast, of the sides of the breast and of the vent broadly edged with white, so that the undersurface is much more white than in the two preceding specimens. Also in this example a few white feathers, especially on the breast, are scattered between the brown ones. This specimen is much like the female, which I described and figured last year as a hybrid. In a female shot at the same date and at the same place (plate 6, fig. d) the feathers of the breast and vent are white, but some brown feathers with white edgings are scattered between them. The two last-named birds have been sexed by myself, they were old females, at least in their second year. The specimens with the brown undersurface are in the summer plumage, which is laid on as breeding has com- menced and which is worn by the birds for only about two or three months, as already in the last of August or the beginning of September the white feathers of the win- terplumage appear between the feathers of breast and vent, and replace the brown feathers of the summer plumage. Notes from the Leyden Museum, Vol. XX XI. 216 ON BIRDS FROM THE NETHERLANDS. Old females in winter plumage have the lower breast and the upper vent pure white, the dark brown upper breast sharply defined from the white lower breast (plate 6, fig. e, 9). The lower vent and the under tailcoverts are dark brown, the feathers more or less edged with whitish, in most of the examples; only in one specimen, shot 14 Fe- bruary 1906 at Nieuwkoop (plate 6, fig. f), the under tailcoverts and the lower vent are white. In females of the first year the dark brown upper breast, the feathers of which are edged with whitish, is less clearly defined from the white lower breast; the vent and under tailcoverts are dark ashy brown, more or less broadly edged with white and also not sharply defined from the white lower breast (plate 6, fig. A). The amount of white feathers at the base of the bill varies much; in adult as well as in young females there are white feathers at the base of the bill; sometimes these feathers are almost wanting, both in old and in young females, Also the white on the chin varies considerably; in some specimens, adult and young ones, the whole chin is white, whereas in other ones white feathers are not to distinguish. Harelda hyemalis (L.). We received again several adult specimens in the last of December 1908 and in January and February 1909 from Texel and den Helder, and besides these, two speci- mens shot on inland waters, viz.: a young male, shot 3 November 1908 at Nieuwkoop, and a young female, shot 18 November 1908 at Voorhout, province Zuid-Holland. Somateria mollissima (L.). Not less than 13 specimens I received last year. A male in change was shot 4 September 1908 on the shore of the province Zeeland, exact locality not given; in the beginning of January 1909 Messrs. H. Leyborne Popham and G. R. Peck presented to our collection 9 specimens, males in change and females, shot in the Veeregat near Notes from the Leyden Museum, Vol. XXXI. ON BIRDS FROM THE NETHERLANDS, 217 Veere, province Zeeland; three further specimens were received, two shot near Texel 29 December 1908 and 27 January 1909, the other 1 January 1909 on the Zuider- zee near den Helder. Grus grus (L.). A young female, shot 28 October 1908 at Deurne, pro- vince Noord-Brabant, is presented to our collection by Mr. R. van Eecke. Crymophilus fulicaria (L.). I purchased two examples, a male in winter dress, shot 3 December 1908 near Texel and a specimen, also in winter dress, in which the sex could not be determined, shot 3 December 1908 on the Zuiderzee near the Anna Paulownapolder. Megalestris skua (Briinnich). The most important additions to our collection of indi- genous birds are two specimens of the great skua, which we received this winter; a female, shot 5 December 1908 on the sandbank „Razende Bol” near Texel, and a male, shot 12 March 1909 near the polder ,,Kendracht’”’ in the north of Texel. Stercorarius pomarinus (Temminck). _ We purchased one specimen, a male, caught in the middle of December 1908 near Hornhuizen, Groningen. It is a bird of the second year; back, rump, wings and tail dark brown, the feathers edged with pale cinnamon; head and undersurface greyish brown, obscurely barred with pale greyish cinnamon; sides of body and under tailcoverts more distinctly barred; under wingcoverts and axillaries blackish brown, barred with white. Wings damaged, bill 34,5 mm. Stercorarius parasiticus (L.). We received two young specimens in the dark brown, Notes from the Leyden Museum, Vol. XXXI. 16 218 ON BIRDS FROM THE NETHERLANDS, varied with pale cinnamon plumage, viz.: 7, shot 8 Sep- tember 1908, on the sandbank „de Hors” near Texel (wing 320, bill 29 mm.) and ©, shot 17 December 1908 near Texel (wing 312, bill 30 mm.). Further two adult specimens in full plumage, both belonging to the pale- breasted phase, viz.: go’, shot 3 May 1909 in the Anna Paulownapolder, Noord-Holland (wing 350, elongated tail- feathers 233, bill 32 mm.) and ©’, shot 10 August 1909 near den Helder (wing 3830, elongated tailfeathers 215, bill 31 mm.). Larus argentatus Brünnich. A clutch of three eggs of this gull, that I found on the dunes of Wassenaar, 18 June 1909, consisted of two normally coloured eggs and one, of which the ground- colour is heron-blue, minutely speckled with pale greyish and with a few large spots of dark olive-brown and black and some clouds of very pale greyish violet, especially at the broad end. All three eggs are of normal size. Larus minutus Pallas. Of this little gull I received the following specimens: ad.

Hydroprogne tschegrava (Lepechin). We purchased the skin of an adult specimen in nearly full plumage, shot in June 1908 by ternshooters on the Zuiderzee near Lemmer, province Friesland. This is the Notes from the Leyden Museum, Vol. XXXI. ON BIRDS FROM THE NETHERLANDS, 219 third specimen in our collection of this in our country extremely rare bird. Uria troille var. ringvia Brünnich. A specimen in winter plumage of the ringed variety, a female, was shot 10 December 1908 on the sandbank „Onrust” near Texel and purchased for our collection. Turdus merula L. An old male in pure black plumage, but with white forehead and crown and with some white feathers at the sides of the neck, was caught on Texel 27 November 1908, and purchased four our collection. Corvus cornix L. A male, shot 16 February 1909 at Westernieland, Gro- ningen, is interesting, as the grey feathers of breast, sides of body and hind neck are minutely and obscurely barred with somewhat darker grey; the feathers of the back show, under certain light, also obscure bars. Corvus corax L. We received one specimen, a female, shot 11 March 1909 near den Helder, when the bird was flying over sea. Serinus serinus (L.). This species was still wanting in our collection of native birds. In the last of April 1909 a male was captured near Harderwijk, prov. Gelderland, and purchased for our collection. Loxia curvirostra L. The common crossbill has been observed in large num- bers in our country this summer; already in the middle of June large flocks have been seen. I received 19 speci- mens from Harderwijk and from Texel. One male, a young one in the red-yellow, mixed with grey plumage, is interesting by the conspicuous white mar- Notes from the Leyden Museum, Vol. XXXI. 220 ON BIRDS FROM THE NETHERLANDS. gins to greater and median wingcoverts. The wing in this specimen measures 93 mm. We have more such examples with white margins to the wingcoverts in the collection, among which an example presented by C. L. Brehm in 1848 s.n. Crucirostra rubrifasciata. Formerly I thought, these were hybrids between Lozia curvirostra L. and L. bifasciata (Brehm), but now I am with Dr. Hartert, who considers them as individual aberrations (Vög. paläarkt. Faun. Heft II, 1904, p. 118). Leyden Museum, September 1909. DESCRIPTION OF PLATE. Females of Fuligula fuligula (L.). Fig. a, 12 August 1909, Nieuwkoop. Summer plumage, adult specimen.
