554 RHYPHID.E. 



posterior cross-vein and the anal vein narrowly suffused with 

 black. Halteres pale yellowish brown. 



Length 3| millim. 



Described from a specimen in good condition in the Indian 

 Museum collection, from Siliguri, 18-20. vii. 07. 



This species is very near R. maculipennis, Wulp, but I believe 

 it is quite distinct, differing in the wing marks and in the wholly 

 yellowish hind femora, these joints in Wulp's species having a 

 black ring in the middle. The palpi, too, in Wulp's species are 

 blackish, and the thorax is described as yellow with black stripes.

3 $ . Head dusted with light grey. Eyes in male quite con- 

 tiguous for a considerable distance, in female separated by a frons 

 about one-fourth to one-fifth the width of the head ; ocelli placed 

 on a small protuberance ; proboscis and palpi blackish brown. 

 Antenna black. Thorax pale bluish ash-grey, varying to yellowish 

 grey, with three chocolate-coloured stripes of the usual pattern, 

 the median one attaining the anterior margin ; sides of thorax 

 concolorous, with a more or less distinct brownish line from 

 the base of the wing to below the shoulder. Scutellum yellowish, 

 more or less dusted with grey ; rnetauotum dusted with grey or 

 bluish grey. Abdomen dark brown, with pale yellow pubescence, 

 posterior borders of segments narrowly yellowish, often the whole 

 abdomen blackish, but in most specimens the basal segment quite 

 pale. Belly yellowish. Legs yellow, posterior femora and tibiae 

 narrowly black at tips, hind femora often with a broad brownish 

 more or less distinct band in the middle ; tarsi blackish towards 

 tips. Wings nearly clear ; stigma dark brown (or black in life), 

 enclosed oy the turned-up tip of the 2nd longitudinal vein ; the 

 apical (more correctly, subapical) spot encloses the 3rd vein just 

 before its tip, and above this vein the spot reaches the wing- 

 border, but below the vein the spot ends abruptly a little way 

 before the wing-border.f The wing is dark brown, narrowly

t In some specimens the spot is roughly triangular, as in typical fcnestra lis, 

 which serves to prove that the present form is more likely to be a variety only 

 than a distinct species.
