ARGYRAMdBBA. 221 



hairs ; ocellar triangle inconspicuous ; face blackish, with hairs 

 which from above appear whitish grey ; antennas with 1st joint 

 black (remainder missing) ; proboscis withdrawn, with mouth- 

 border reddish brown ; back of head only slightly puffed out, 

 blackish grey, with some whitish hairs. Thorax shining black, 

 with some yellowish-white hairs and stiffer bristles towards the 

 posterior corners ; sides of thorax black, with some whitish hairs ; 

 scutellum dark cinereous grey, with vestiges of some short yellow 

 hairs, and a few pale yellow bristles on posterior margin. 

 Abdomen blackish grey, with a slight brownish fringe, covered- 

 more or less sparsely with short pale yellow hairs, most con- 

 spicuous on borders of segments ; a bunch of whitish hairs on 

 each shoulder of the 1st segment ; venter with whitish hairs. 

 Legs : coxae yellowish grey, with whitish pubescence ; femora and 

 tibiae pale yellow, the latter with minute bristles ; tarsi blackish 

 towards tips. Wings nearly clear ; a rather bright yellowish- 

 brown baso-costal band extends along the costa just beyond the 

 middle, thence extending posteriorly along a line comprising the 

 inner cross-vein, the base of the discal cell, and the outer side of 

 the second basal cell ; below this cell the colour immediately fades 

 away to a pale grey, which covers the anal and axillary cells. 

 Appendix of the upper fork of tlie 2nd vein short but distinct. 

 Halteres creamy yellow. 



Length, 5 mm. 



Described from a perfect specimen (except for the missing 

 antennae) in the Indian Museum from Hathikund, Grarhwal 

 District, base of Western Himalayas, 3. v. 1909. 



169. Argyramceba intermedia, sp. nov. 



J 2 • Closely resembling Aphcebantus ceylonicus, Brun. An- 

 tennal 3rd joint short onion-shaped, prolonged into a long style, 

 with the tip bisected, bearing the normal pencil of hairs and 

 a central microscopic bristle ; 1st antennal joint flattened and 

 spread out, whitish, with white, not black, bristles. 



It differs from ceylonicus as follows :— (1) In the subfamily 

 character of the comparatively long praefurea, which in Aphcebantus 

 is relatively short ; in intermedia the 2nd and 3rd veins diverge 

 opposite half-way between base of discal cell and the anterior 

 cross- vein. (2) Frons in S of appreciable width at vertex (in 

 ceylonicus the eyes are almost contiguous there) ; frontal pubes- 

 cence more whitish than yellow. (3) General pubescence of 

 thorax, pleurae, and abdomen yellowish grey or whitish, never 

 bright yellow 7 . (4) Abdomen wholly blackish grey. (5) The 

 baso-costal half of wing rather bright brown ; the line of demar- 

 cation running from tip of 1st vein to tip of anal cell, cutting the 

 discal cell at about its middle ; the outline mainly straight, but 

 not sharply defined. (6) Basal half of anterior femora, and all 

 the hind femora (except narrowly at base and, perhaps, tip)
