 punctured, with the elytra finely strigose except on the disk ; 

 tiie forehead is feebly impressed and somewhat elevated over 

 the eyes ; the thorax, nuirginal stria complete and obscurely 

 crenate behind the neck ; the elytra, outer humeral stria 

 complete, raised, but not carinate, and there are short traces 

 of two dorsal strise ; the pygidia are finely and densely 

 punctulate; the prosternum, anterior lobe coarsely and some- 

 what rugosely punctured, keel less closely punctate, especially 

 at the base, the stride turn slightly inward anteriorly; the 

 niesosternum is not quite straight, being very slightly arcuate 

 behind the prosternal keel, punctured like the keel, and very 

 narrow and transverse, sutural stria rather widely and irregu- 

 larly crenate. 



The original notice of this species gave insufficient cha- 

 racters; it may be placed near 2\ bicarinatiis, unistriuSj and 

 cijclonotus, Lew., but the last is a convex species; all are 

 Uiiental.
