punctures anteriorly, obliquely and more coarsely posteriorly; 

 the notauli distinct, meeting each other beyond the middle of 

 the segment, which is feebly depressed in the middle poste- 

 riorly. Scutellum longitudinally rugose-striate ; with a deep 

 transverse depression at the base, in which are several longi- 

 tudinal carinse ; the sides of the scutellum with marginal 

 caring;, the apex narrowly rounded. Median segment short, 

 rugose, with a transverse carina at the apex, the areas 

 obliterated by the coarse sculpture, the sides of the segment 

 clothed with pale hairs. Abdomen coarsely longitudinally 

 striated ; first tergite subsessile, a little longer than its apical 

 breadth ; the spiracles situated near the middle of the lateral 

 margins, a curved carina connecting them ; second tergite 

 broadly transversely depressed before the apex, nearly twice 

 as broad as long ; third tergite more shallowly transversely 

 depressed behind the middle, as long as the second segment ; 

 the apical segments small. Terebra very short, the valvulae 

 projecting very little beyond the apex of the abdomen. 

 Second transverse cubital nervure missing ; nervulus a little 

 prefurcal. Nervellus elbowed and intercepted just below the 

 middle.

The genus was founded by Cameron in 1911 for three 

 species from Ceylon and India, which are closely related to 

 the Australian species. The spines on the male abdomen are 

 on the third tergite in this species, not on the fourth, as stated 

 by Cameron in the description of his species.
