Described from the unique tgj^e in the Indian Museum collection, 

 from Chonebal, Nepal., 



Only the type-specimen is known *, and it is now in bad con- 

 dition. Its principal difference from aiirifrons is the larger size, 

 8 mm. as against 5-6|, and the sparse whitish pubescence of the 

 eyes as contrasted with the dense yellow pubescence in aurifrons.
