TRICIIOCEIIA. 511 



speaks of the grey spots in the wings forming parts of circles, 

 presumably after the fashion of the markings in the Tabanid genus 

 Hcematopota. The rest of his short description would apply very 

 well. The present description is based on the individual specimen 

 herein referred to, no part of Walker's description being incor- 

 porated ; so that in the event of my identification being incorrect, 

 all that will be required will be to provide a ne\v name for the 

 species described here. 



365. Trichocera punctipennis, sp. uov. (PL X, fig. 13.) 



tf $ . Head : vertex, f rons, back of head and proboscis dark 

 grey or cinereous grey ; frons from one-half to one-third the 

 width of the head ; eyes contiguous below, flattened. Palpi dark 

 brown, considerably elongated. Antennal scape reddish brown 

 or brownish yellow, flagellum brownish yellow or dirty black, 

 very attenuated towards tip. Tliorax cinereous grey or dark grey, 

 dorsum darker grey, normally with a median pair of narrow 

 well-defined and rather widely separated dark brown lines 

 attaining the anterior margin ; a shorter dark brown narrow 

 stripe on each side ; a small dark grey spot near the tips of the 

 median stripes, on the outer side. In some specimens no distinct 

 dorsal stripes are visible, in some the dorsum is rather darker 

 grey, the colour carried forward as a wide median stripe to the 

 anterior margin ; in these cases the dorsum behind the suture is 

 darker grey, the median post-sutural depression and dorsum of 

 scutellum greyish, the edges of the scutellum pale, the metanotum 

 darker. Sides of thorax more or less yellowish grey. Abdomen 

 dark brown, with rather numerous pale hairs, posterior margins 

 of segments more or less broadly yellowish ; belly similar. Genital 

 organs of male brown, elongate, with a pair of slender yellowish 

 flexible appendages. In the female the ovipositor is small, 

 normal. Leys brownish yellow, with a pale blackish subapical 

 ring on the femora ; tips of tarsi darker. Winys very pale grey, 

 with pale grey or brownish grey spots. Auxiliary vein ending at 

 or just before three-fourths of the length of the wing, exactly 

 opposite the marginal cross- vein ; the 1st longitudinal vein ending 

 a short distance beyond, half-way between the marginal cross- 

 vein and the tip of the anterior branch of the 2nd vein ; the 2nd 

 vein begins at a little before the middle of the wing, nearly at a 

 right angle, the prsefurca being rather more than half the whole 

 length of the wing, the fork occurring just before the marginal 

 cross- vein, the branches parallel ; the 3rd vein begins beyond the 

 middle of the praBfurca, at a right angle, running parallel with 

 the 2nd vein ? anterior cross-vein nearly in a line with the basal 

 section of the third vein, and of about the same length ; discal 

 cell actually pentagonal, but approximately triangular ; upper 

 branch of 4th longitudinal vein forked before the middle (after
