The form of the hinder femora and tibiae most nearly 

 resembles those of the Indian N. comdrista a.nd the African 

 A^. calida, but otherwise it is very distinct. The femora 

 are formed pretty much as in A^. cJirysopa, but otherwise 

 there is no resemblance. 



Head black ; front and vertex strongly punctured ; 

 sparsely covered with short, fuscous hair; a smooth furrow 

 runs down from the ocelli ; the face and clypeus densely 

 covered with pale golden pubescence ; the base of the 

 clypeus yellow, the middle rufous, the apex black. The 

 scape of the antennae yellow, rather thickly covered with 

 long, white hair ; the flagellum rufous, slightly darker in 

 the middle above. Pro- and meso-notum with the scutel-

 Wings hyaline ; the apex distinctly smoky ; the costa, 

 stigma, and nervures fulvous ; the second cubital cellule

 the coxae and trochanters black ; the four anterior femora 

 for the greater part above ; and the basal two-thirds of the 

 hinder fem.ora ferruginous ; the hinder femora large, 

 broadly rounded above ; the base, before the tooth, 

 straight ; the tooth oblique, directed towards the apex ; 

 the outer side of the apex of the hinder tibiae curved ; 

 the inner projecting, in width not much less than half of
