joints very distinct, black, with grey pubescence. Thorax dull 

 black, blackish brown, or blackish grey ; dorsum barely darker, 

 sutures barely lighter. Two widely separated rows of dorso- 

 ceiitral stiff hairs. Scutellum, metanotum, and sides of thorax 

 concolorous. Abdomen black, with a little very short golden grey 

 pubescence at the sides, and here and there on dorsura and belly, 

 the pubescence apparently sparser in the female. Belly dark 

 brown. Legs : coxa3 black, remainder of legs (including tro- 

 chanters) brownish yellow ; tips of tarsi blackish. Winys very 

 pale yellowish grey, nearly clear, iridescent. Auxiliary vein 

 ending above the fork of the 2nd longitudinal vein, which latter 

 originates before the middle of the wing, the praef urea being short, 

 considerably curved, and much less than half as long as the 

 remainder of the vein ; submai'ginal cell distinctly longer than the 

 1st posterior cell ; base of 3rd vein in a line with anterior cross- 

 vein and of about the same length ; discal cell twice as long as 

 broad, considerably shorter than the 2nd and 3rd posterior cells ; 

 posterior cross-vein situated just beyond middle of discal cell ; the 

 3rd vein and the veinlets of the 4th vein issuing from the discal 

 cell are all lined with very short hairs. Stigma over marginal 

 cross- vein (just beyond middle of marginal cell), small, brown, 

 narrow but distinct, yet with ill-defined edges. Halteres yellowish, 

 clubs blackish brown. 



Length 6 millim. 



Described from one male and two females taken at Pallode, 

 20 miles N.E. of Trivandrum, Travancore, 15. xi. 08 (Annan- 

 dale}. 



Types in the Indian Museum. 



The length of the longitudinal veins in the distal half of the 

 wing approximates the wing of this species to that of L. longi-. 

 nervis. The hairy veins are a character of this species.

 side. Ovipositor black, shining; valves reddish brown, short, 

 Legs brownish yellow ; tibiae a little darker. Wings pale grey,, 

 somewhat narrow, distinctly vitreous and iridescent. Auxiliary 

 vein ending at one-third of the distance between the origin of the 

 2nd longitudinal vein and the tip of the 1st ; the 2nd vein 

 originating at the middle of the wing, the prsefurca nearly as long 

 as the remaining portion ; basal part of 3rd vein longer than 

 anterior cross-vein ; discal cell not much longer than broad ; 

 posterior cross-vein distinctly before the discal cell. A brownish
