 all percurrent. Eyes elongate, not rounded laterally. Hind tibiae 

 with seven to nine spines. Lateral keels of pronotum obsolescent. 

 Apical margin or tegmina broadly multireticulate. 



Superficially rather like Acania Stal, but the front is not angu- 

 lately ampliated ; the pronotum is rather deeply emarginate, the 

 fore tibiae are not at all dilated and the hind tibiae are at least 

 quadrispinose apical of the middle.

 two-thirds yellowish, apex of hind tibiae and the hind pairs, red-
