the base of the basal cells, the colour continued forward into the 

 1st basal cell, leaving a small clear spot; a square spot over base 

 oE prsefurca and extending across the middle of the 1st basal cell 

 almost to the 4th vein ; an irregular long spot beginning on the 

 costa above the tip of the 1st vein and marginal cross-vein, 

 extending downwards to the distal end of the 1st basal cell ; a 

 small, very dark spot over subcostal vein. Pale blackish irregular 

 markings over tip of wing, over the cross-veins and distributed 

 over hinder part of wing. Halteres yellowish, clubs black. 



Length 6 millim. 



Described from a perfect male from Kurseong, 26. vi. 10

" Head shining dark purple, almost metallic, slightly hairy on 

 vertex. Antennae with the scape ochreous, the flagellum fuscous, 

 clothed with a rather dense pubescence ; joints ovate-cylindrical, 

 about twice as long as broad. Thorax shining blue-black, sub- 

 metallic ; mesopleune dull whitish. Abdomen with the 1st segment 

 and the base and sides of the 2nd shining blue-black, the remainder 

 of the dorsum purplish brown, somewhat shining, venter brown. 

 Legs : coxae, trochanters, and basal f of femora ochreous, apical 

 fourth of femora brownish or purplish black, preceded by a pale 

 ochreous ring ; the apices of all the femora are thickened, those 

 of the hind legs to the greatest extent. Tibiae and tarsi of the 

 fore and hind legs greyish ochreous, darker towards the tips. 

 Hind tibiae with the basal two-thirds ochreous, apical third 

 blackish and somew^hat thickened. Hind tarsi blackish except for 

 basal half of metatarsus, which is ochreous. Wings hyaline, 

 iridescent, with four brown cross-bands, which are darker towards 

 the costa ; the hrst of these is at the base of the basal cells, the 

 second is mainly before, but includes the origin of the prtefurca ; 

 the first extends only half-v/ay across the wang and is connected 

 with the second by a longitudinal brown patch occupying the 

 space between the 5th and 7th veins ; the third and broadest 

 band includes the cross-veins, lying mainly beyond them ; it is 

 broadest in the middle of the wings, and extends to the apex of 

 the discal cell ; the fourth band occupies the whole of the apex 

 of the wing. The praefurca arises about the middle of the wing, 

 and is obtusely angulated near its base. Marginal cross-vein 

 considerably beyond the fork of the radial vein, and near the 

 termination of the subcostal. Small cress-vein almost in a line 

 with base of submarginal cell, situated at the base of the discal
