cross-vein divides the marginal cell into an inner and outer cell, 

 the latter the longer one of the two ; but even this cross-vein 

 is absent in van der Wulp's coloured figure. The t\vo submarginal 

 cells are naturally separated by the lower branch of the 2nd 

 longitudinal vein, the upper cell being the shorter. The petiole 

 of the 2nd posterior cell is much shorter than the cell. 



397. Eriocera semilimpida, Brim. (PL X, fig. 17.) 



Eriocera semilimpida Brunetti, Rec. Ind. Mus. vi, p. 311 (1011). 



cJ . Head wholly black, vertical protuberance with some black 

 hairs ; antenna? black, shortly pubescent ; palpi nearly black. 

 Thorax shining black, with some dark brown hairs about the sides ; 

 mesonotal suture deeply cut ; greyish reflections behind and below 

 base of wing ; scutellum shining black, with soft black hairs ; 

 metauotum shining black. Abdomen : 1st segment livid on basal 

 half, remainder black ; next four segments reddish orange, hind 

 borders a little darker, that of 5th blackish ; rest of abdomen 

 black, including the genitalia, which are of moderate size, the only 

 obvious parts being a tolerably large pair of claspers. Belly 

 mainly as dorsum, 1st segment all black, 2nd black except at 

 base. Legs wholly black, shortly pubescent. Wings dark grey, 

 slightly tinged with yellowish ; costal cell, 5th longitudinal vein, 

 and distal part of wing from about the inner side of discal cell, 

 rather dark brown, the colour extending not quite so far 

 proximally into the marginal and 5th posterior cells ; hind basal 

 corner of wing more or less brown. Inner cross-vein placed soon 

 after origin of 3rd vein, and before fork of 2nd ; branches of 2nd 

 rather close together, fork of upper branch occurring before one- 

 fourth the length of that branch ; discal cell 6-sided ; upper 

 branch of 4th vein forked near tip, making five posterior cells ; 

 the three veinlets from the discal cell equidistant ; outer cross- 

 vein just beyond middle of discal cell. Halteres black. 

 Length 12 millim. 



Described from one male in the Pusa collection, taken in the 

 Khasi Hills, ix. 1906, and a second specimen from Nongpoh, 

 Assam, vi. 06. 



Type and second example in the Pusa collection. 

 This species bears close general resemblance to E. bicolor, 

 Macq., but there are several quite good points of difference 

 between them. In E. semilimpida the head is black, not 

 greyish ; the thorax shining black unmarked, not brownish 

 grey with three black bands and some small spots ; the basal 

 segment of the abdomen is black, not orange ; the coxa3 

 black, not tawny ; the costa dark brown throughout its length, 

 not clear on the whole proximal half, as distinctly mentioned by 

 Macquart and illustrated in his plate ; and the whole proximal 

 two-thirds of the wing (apart from the costa) in my species is 

 pale grey, whereas in E. bicolor the whole wing is brown, with a 

 broad clear median band, and a narrower one at the base. The 

 venation is identical in the two species.
