nearly as long as tibia, flattened, broad at tip ; 2nd joint rather 

 more than half as long as first, narrower, cylindrical, thickened ; 

 3rd joint nearly as long as 1st, much incrassated, broader and 

 much longer than 2nd and broader at tip than at base ; 4th joint 

 about as long as 3rd, narrower, thin, considerably arched, so that 

 the underside forms a large cavity ; 5th joint shorter than 4th, 

 moderately incrassated, bluntly conical ; claws and pulvilli normal. 

 Pubescence on coxa3 and femora moderately long and dense, a little 

 thicker on hind femora, with a few longer hairs on outer side ; 

 front tibia3 with a row of short hairs on inner side, a row of longer 

 ones on outer side, and a row of very long ones on upper side ; 

 middle tibiae moderately pubescent, with two long bristles on outer 

 side (one at middle, one preapical) ; hind tibiae covered with rather 

 dense, moderately long pubescence and longer hairs, and with a row 

 of quite long hairs on hinder side; anterior tarsi with 1st joint 

 nearly bare except for a few hairs towards tip, remaining joints

with long dense hairs on upper and outer sides, a few short hairs 

 on inner and lower sides, the 4th also bearing a denser bunch on 

 upper side near tip. Wings pale grey ; venation approximately

Described from a single <3 from the Pusa collection from 

 Belgaum, Bombay Presidency, 2500 ft., 11. viii. 1910 (Fletcher], 

 presented to the British Museum. 



A label attached by Mr. T. Bainbrigge Fletcher says : " Fore- 

 legs are stretched out in front and function as antenna?; they 

 are not used for locomotion." The extraordinary development 

 of the front tarsi easily distinguishes this species from all other 

 Indian EMPID.E, yet this character is the only one in which it 

 differs from typical species of Empis.
