5 . Head: eyes nearly contiguous ; back of head on upper half 

 brown, on lower half blackish grey. Proboscis brownish yellow ; 

 palpi blackish. Antennal scape dark grey, flagellum blackish. 

 Thorax brownish yellow ; centre of dorsum occupied by two 

 contiguous concolorous stripes from anterior margin to suture. 

 Scutellum, metanotum, and sides of thorax concolorous, ^itli 

 lighter reflections here and there. Abdomen brownish yellow, the 

 major part of the doi-sum of each segment dark brown ; pubescence 

 very short. Belly mainly yellowish, with indistinct blackish 

 marks. Ovipositor compact, robust, apparently more complex 

 than usual, terminal blades short. Legs brownish yellow ; femora 

 becoming rather darker towards the tips, but the tips themselves 

 broadly of the prevailing paler colour. Winr/s grey. Auxiliary 

 vein ending half-way between the origin of the 2nd longitudinal 

 vein and the tip of the 1st ; the 2nd vein originating some distance 

 before the middle of the wing, the pra3furca rather short ; the 3rd 

 vein beginning just beyond the tip of the prtefurca ; the anterior 

 cross-vein in a line Avith the basal side of the discal cell, which is 

 about twice as long as broad ; all the fine veins running to the 

 wing-border parallel ; posterior cross-vein just before middle of 

 discal cell. There are two small pale grey suffusions over the 

 base of the 2nd vein and the tip of the 1st, respectively ; a third, 

 over the tip of the auxiliary vein is indistinctly continued along 

 the fork of the 2nd vein, the base of the 3rd and the anterior 

 cross-vein, whilst there is a trace of grey suft:'usion over the distal 

 sides of the discal cell and over the posterior cross-vein. Halteres 

 blackish. 



Length 9 millim. 



Described from a single perfect female from Kurseong, 5. ix. 09 

 (Annandale). 



Type in the Indian Museum. 



The peculiarity of this species is the length of the 2nd, 3rd, 

 and 4th veins, due to the 2nd vein originating much nearer the 

 base of the wing than is usual, thus giving the wing some 

 resemblance at a casual glance to that of a Libnotes.
