Description. Belongs to Cameron’s section IV. “ Tarsal claws with 
two teeth (Sphez, sensu str.).” 
Head black, opaque, finely punctured, covered with soft scattered 
grey hairs, the clypeus and cheeks with silvery pubescence ; the 
elypeus sub-triangular, slightly convex, its anterior margin transverse ; 
mandibles black ; antennz arched, the scape short, the 2nd and 38rd 
joints sub-equal ; the ocelli very small and inconspicuous, placed in a 
curve on the vertex. Thorax black, finely punctured, covered with 
thin grey pubescence, that on the proscutellum short, dense, 
and silvery ; the mesothorax indented anteriorly in the centre; 
the metathorax evenly rounded, the scutellum and _ proscutellum 
not raised and the latter not indented in the middle as 
in so many species. The wings hyaline, the anterior wings with a 
fuscous cloud beyond the radial and 3rd cubital cells not coming 
lower than level with the base of the laiter, the nervures ferruginous, 
the tegule black and shining. Legs black, the apex of the tibie of 
the posterior legs clothed with rich golden pubescence on the inner 
side, Abdomen black, very finely punctured, the 2nd segment dark 
blood red, the rest narrowly margined with testaceous brown. 
The ¢ resembles the Q, but has larger wings and a more lengthened 
petiole. 
This well marked little species is very common at the beginning 
of the rains on the flowers of Acacta pennata. 
Family BEMBECID 4, Westwood. 
This family, so far as I know, is represented by several species in 
Burma and Tenasserim. Of these three have not as yet been described.
