 branching little above the posterior ocelli, widely sulcate ; posterior

 rather short, scarcely reaching to the humeral angles, inserted dis- 

 tinctly between the eyes. Pronotum deplanate, fossulate at the base 

 of process, between the shoulders convex ; process of pronotum 

 extended backward beyond the apices of the posterior femora ; 

 lateral lobes having the posterior angles turned down, obtuse.

Body slender, granulate, colour cinereous very obscurely variegated 

 with fuscous on sides and legs ; eyes globose ; vertex viewed in front 

 subnarrower than one of the eyes, viewed from above bearing 

 strongly oblique carinulne convergent forward and extended back- 

 ward on each side to the middle of the eyes, the vertex here a little 

 widened, middle carinate, on each side somewhat foveate ; frontal 

 costa arcuate, viewed in front rather widely sulcate, the rami evenly 

 divergent. Pronotum anteriorly truncate, posteriorly lengthily 

 acuminate subulate, extended much beyond the apices of the pos- 

 terior femora ; dorsum deplanate, bearing two indistinct, abbreviated 

 granulate cavinula? between the shoulders ; median carina very thin 

 but little incrassate between the shoiUders, here undulate then 

 depressed behind, and straight on the process and less distinct ; 

 prozonal carinae parallel, very lightly expressed ; lateral carinae 

 passing forward on the shoulders biit indistinctly expressed ; 

 humeral angles having the carina) more expressed, widely angnlate ; 

 posterior angles of lateral lobes turned down, obtuse. Elytra oblong 

 having rounded apices ; wings fully explicate reaching to apex of 

 pronotum in male. Anterior and middle femoral margins entire ; 

 posterior femora elongate, the pra?gcnicular lobe small, spiculate, the 

 genicular lobe minute ; posterior tibiaj armed with small spines and 

 serrulate ; the first articles of the posterior tarsi little longer tlian the 

 third, and having the pulvilli flat below, the third longer than the 

 second.
