 gently curved at the tip.

352. Gnophomyia furcata, sp. nov. (PI. IX, fig. 18.) 



6 2 . Head : occiput blackish grey. Proboscis and palpi dark 

 brown . Antenna? yellowish brown, the colour varying in intensity, 

 with sparse pale pubescence. Neck yellowish brown. Thomas 

 light yellowish brown, shining, dorsum with a few pale hairs : 

 sides of thorax more or less shining yellowish brown. Scutellnm 

 and metanotum shining yellowish brown. Abdomen brownish 

 yellow, with some pale pubescence ; rather darker brown in 

 female. Belly lighter. Genitalia of both sexes yellowish. Legs 

 pale yellowish, tarsi darker. Wings practically clear, slightly 

 iridescent; stigma very indistinct, yellowish grey. Auxiliary- 

 vein ending considerably beyond the origin of the"2nd lougitudiual, 

 the subcostal cross-vein being towards tlie tip of the former ; the 

 2ud vein forked much sooner than in Gonomi/ia, the branches 

 diverging, the posterior one slightly the longer, the anterior one 

 joined (at about one-third of its length) to the 1st longitudinal 

 (near the tip of the latter) by the marginal vein, which in some 

 specimens is indistinct ; the 3rd longitudinal with a short basal 

 portion, the rest being straight and parallel to the vein above it ; 

 anterior cross-vein moderately long; discal cell closed, sub- 

 triangular, its inner side very short ; anterior branch of 4th vein 

 widely forked beyond half its length; 5th, Gth and 7th veins 

 nearly straight, with the exception of the small downward curve 

 of each towards its tip ; 1st posterior cell twice as wide at base 

 as at tip. Halteres pale yellow. 



Length 3-3 J- millim. 



Described from several specimens of each sex in the Indian 

 Museum, from Darjihng, 7000 ft., 5-10. viii. 09 (Paivn).

In the_ forking of the anterior branch of the 4th vein this 

 species differs from others in this genus, so far as I am aware, 

 yet it undoubtedly belongs here. I refrain from establishing a 

 new genus on this character alone, in view of the variable nature 

 of the venation in the closely allied genus Gonomyia, and the 

 tendency to specific and adventitious variation in allied genera. 

 Besides, Osten Sacken in describing his two North American 

 species, G. luctuosa and tristissima, notes a difference of venation 

 in them. The wing of the present species differs somewhat from 

 Osten 8acken's plate (Monog. N. Am. Dipt, iv, pi. ii, fig. 5) as in 

 that (G. tristissima) the marginal vein occurs at the fork of the 

 2nd vein, the contact of the 3rd longitudinal vein with the 2nd is
