Head flat, front rugose; epistoma narrowly and deeply emargi- 

 nate in front, the emargination forming a semicircle, and the sides 

 produced into an acute lobe, not narrowed by the antennal cavities, 

 which are large, somewhat triangular, and situated under a distinct 

 carina at some distance from the inner margin of the eyes. An- 

 tennae 11-jointed, rather long and slender; first joint clavate, 

 elongate and abruptly arcuate near base; second obconic, about one- 

 half as long as the third; third elongate, slightly flattened, and 

 about three-fourths as long as the first; fourth and fifth elongate, 

 about equal in length to the third and feebly enlarged at apex ; the 

 following joints gradually becoming shorter toward the terminal 

 joint, triangular, strongly enlarged at apex (except the last joint, 

 which is oval), and strongly dentate on the inner side; joints four 

 to eleven armed with a large subterminal poriferous fovea. Eyes 

 elliptical, oblique, and nearer to each other on the vertex than at 

 the front. Pronotum wider than long, trapeziform, disk moder- 

 ately convex; sides obliquely narrowed anteriorly; anterior margin 

 sinuate, with a median lobe; base nearly truncate. Scutellum sub- 

 pentagonal, a little wider than long, and attenuate posteriorly. 

 Elytra elongate, truncate at base, without distinct basal depressions 

 and entirely covering the pygidium; sides nearly parallel in front, 

 then strongly acuminate to the tips, which are strongly bidentate, 

 the lateral margins unarmed. Sternal cavity formed by the meso- 

 sternum and metasternum, the lateral branches of the former elon- 

 gate and curved. Metasternum lobed in front. Prosternum with the 

 anterior margin truncate at middle, and strongly lobed on each side ; 

 prosternal process wide, arcuately emarginate between the anterior 

 coxae, and acuminate at apex. Posterior coxae distinctly dilated in- 

 ternally; anterior margin straight; posterior margin oblique. Legs 

 rather robust; anterior and middle femora strongly swollen at mid- 

 dle; tibiae slender and cylindrical; tarsi rather long; first joint of 

 posterior pair about as long as the following two joints united; sides 

 of third joint prolonged beyond the fourth; tarsal claws with a 

 feeble tooth at base. 



This is a monobasic genus, and the name was first used by Saun- 

 ders (1871) for tereticollis Pallas without giving any description. 

 Thomson (1878) described the genus and uses the same name.
