ti-ansverse cubital nervure obliqvie, "Wings hyaline, nei^vures 

 white. 



Colours as in bidentata. 



Length 10 mm. 



Hab. Grahamstown, S. Africa. 



I have seen neither bidentata nor lacteipennis. Cameron's 

 statement that the ungues of the hind tai'si are simple, not bifid, 

 needs confirmation.

S . Slender ; antennae stout, tapering towards the apex ; 

 pronotiim scarcely more than half as long as the scutellum, 

 moderately narrowed anteriorly. First dorsal segment nearly half 

 as long again as the apical breadth ; seventh dorsal segment 

 rather narrowly rounded at the apex. Tarsal ungues bifid ; 

 hind tibia? serrate ; hind femora without a distinct lobe at the 

 apex beneath. Apical joint of maxillary palpi filiform. Second 

 abscissa of the radius twice as long as the first, the two combined 

 nearly as long as the third; first transverse cubital nervure 

 oblique, sharply bent near the cubitus, longer than the second ; 

 the distance between the cubitus of the hind wing and the 

 transverse median nervure equal to half the length of that 

 nervure. 



Black : mandibles, clypeus, scape beneath, a spot on each side 

 on the posterior margin of the pronotum, the base of the tegulfe. 

 a small spot on the mesonotum, one on the scutellum, another on 

 the postscutellum, the two latter spots sometimes absent, and the 

 anterior coxae beneath yellow ; legs ferruginous. Wings hyaline, 

 nervures fuscous.
