the vertex. Thorax ctneous, with a little hronze reflection when 

 viewed from certain angles; two median well-separated stripes of

short bright yellow pubescence, of which there is also a little at

Described from a c? from Singla, iv. 1!)13, and a 2 from 

 Darjiling, 1000-3000 ft., v. 1912. Another specimen from above 

 Tura, 3500-3000 ft., 15.viii-30. viii. ]9\7 (Kemp). 



The hind femora are much more incrassated than is normal in 

 Xylota, but the species fits into this genus better than elsewhere. 

 It might be placed in Syritta, to which its general resemblance is 

 striking, but for the position of the anterior cross-vein.
