dark grey, nearly blackish, covered with golden yellow hairs. 

 Proboscis and palpi blackish, the former with well-developed 

 labella at the tip, the latter with the first joint distinctly the 

 largest.* Antennae more or less reddish brown in the type male, 

 the scape and two basal flagellar joints reddish,*}" in one female 

 wholly red. in the other only slightly so at the base ; in all cases 

 with whitish pubescence over the whole flagellum. A row of 

 whitish hairs behind the eyes encircling the back of the head. 

 Thorax wholly rather dull but obviously reddish brown on dorsum, 

 covered with bright golden yellow hairs ; sides of thorax wholly 

 blackish grey. Scutellum reddish brown, metanotum dark grey. 

 Abdomen blackish, the posterior margins of the segments very 

 narrowly whitish, dorsum with a few pale scattered hairs. Legs : 

 apparently normally the coxa? and femora dull reddish brown or 

 brownish yellow, the tibia? and tarsi blackish, but the brownish 

 colour extending at least to the hind femora in one of the female 

 specimens. Hind metatarsus much enlarged in both sexes, 

 especially so in the male, in both sexes as long as, or slightly 

 longer than, the rest of the tarsus and about two-thirds as long as 

 the tibia. Wings clear, venation normal. Halteres brownish or 

 blackish. 



Length 2 millim. 



Described from one male from Kanara, Bombay, viii. 07, and 

 two females from Karwar, Bombay, viii. 07. Two females in the 

 Indian Museum are from Kurseong, 10-26, ix. 09 (Lynch], and 

 7. ix. 09 (type female) (Annandale). 



Type male in the Pusa collection, tvpe female in the Indian 

 Museum.

cJ . Head set very close on the thorax. Eyes with conspicuously 

 large facets on upperside ; a moderately narrow face below the 

 antennae light grey. Antennae black, with rather thick short 

 grey pubescence ; scape brownish yellow. Proboscis blackish, 

 yellowish at tip ; palpi black. Thorax deep velvet-black, evidently 

 originally covered with the short bright yellow hairs common to 

 most of the Oriental species, shoulders -with- 'a broad and square 

 spot of pale blue greyish dusting, the inner corner of the spot 

 nearly rectangular ; also a broad similarly coloured band on the 

 posterior margin. This rather gives the appearance of the dorsum 

 being of a blue-grey ground-colour, with a broad deep black 

 transverse baud occupying the major portion of the surface and a 

 contiguous perpendicular broad stripe reaching to the anterior 



* In the original description the last joint was erroneously given as the 

 largest. 



t Under a strong light, the microscope reveals the whole antenna as dull 

 reddish brown, though the flagellum appears mainly black to the naked eye.
