Described from the tyjH $ in the Britisli ^Nluseum from India, 

 and another $ from the Lower Kanges, N. Khasi Hills, Assam, 

 1878 {Chennell); also from two ^ j taken by Col. Nurse at 

 Deesa, vi. 1897, and Abu; and a $ from Coimbatore, S. India, 

 22.1.1913. liecorded also from Java. The S is not kno\x n. 

 I do not think that this species should remain in /'Jr is I alls, on 

 account of the greatly thickened hind femora ; the dipped 2nd 

 vein is an adilitional ahnorinalitv.
