GNORISTE. 83 



curved, ending a little beyond it, the 3rd vein originating near 

 middle of wing at an angle, thence gently bisinuate, the anterior 

 cross-vein placed at the angle. The 4th longitudinal forks just 

 beyond the anterior cross-vein, the oth at about the same distance ; 

 ^>th vein strong but incomplete. 



Range. Europe, Greenland, North America, Chili, Himalayas. 



Life-history unknown. 



Easily recognised, being the only Oriental genus with a produced 

 proboscis. 



The two Indian species may be separated thus : 



Thorax yellowish, with three dark stripes ; 



proboscis as long as height of head, not 



spatulate at tip brevirostris, sp. n., p. 83. 



Thorax shining black on dorsum ; proboscis 



one-and-a-half times height of head, the 



long broad labella giving it a spatulate 



appearance spathulata, sp. n., p. 84. 



38. Gnoriste brevirostris, sp. nov. (PL III, fig. 7.) 



c? . Head : vertex, f rons and face blackish ; three ocelli, yellow, 

 distinct, in centre of frons, the middle one lower and smaller. 

 Proboscis about as long as the height of the head, broadly conical ; 

 dark brown, nearly black, with a little pale, very short pubes- 

 cence ; labella distinct, brown : palpi pale yellow, long. Antennal 

 scape bright yellow, first two or three flagellar joints yellow, the 

 remainder black, with whitish pubescence. Thorax yellowish, 

 with three broad shining black stripes, the median one reaching 

 the anterior margin, the outer ones a little shorter; all three 

 united behind on the posterior margin. Scutellum blackish. 

 Sides of thorax yellowish, pleurae and metanotum dark brown. 

 Stiff yellow hairs towards the margins of the thoracic dorsum, and 

 a row of very small stiff hairs on the median stripe ; in addition 

 there are irregular, short hairs scattered over the whole of the 

 dorsum. Abdomen black, with pale pubescence, posterior margin 

 of segments with a dull dirty yellow band ; belly similar ; genitalia 

 consisting of several comparatively small pale yellow appendages 

 enclosed in an outer blackish cup-shaped cavity. Legs pale 

 yellowish, trochanters and tarsi blackish. Wings pale grey ; 

 venation normal; most of the longitudinal veins extremely 

 narrowly suffused with brown. Halteres yellowish. 



Length 5 millim. 



Described from a single male from Mundali, Jaunsa Division, 

 Dehra Dun District, 9000 ft., 32.v. 10 (C. W. Beebe). 



Type in the Indian Museum. 



Owing to the drying of the wings the subcostal cross-vein is 

 barely visible, but it is present between the auxiliary vein and the 

 1st longitudinal, about half-way between the humeral cross-vein 

 and the origin of the 3rd longitudinal.
