bisiuuatus. Eli/tra prothoruco duplo longiora, basi lutiora, postice 

 gradatim aiigustiora, bumeris rotuudata. Pedes mediocres, fere 

 lequalcs. Pro- et mesostema inter coxas elevata, baud producta. 



This genus may be placed near Micracantha, Montr. ; but, 

 inter alia, it wants the prothoracic tubercle, and the antenna? 

 have a lonc:er basal joint. The outline of the prothorax and 

 elytra is ditVerent ; and hence the affinity of the two genera is 

 not at once obvious. The species described below is covered 

 •with a whitish pubescence, the elytra having scattered bristle- 

 like hairs, each arising from an areolated puncture. The an- 

 tenna?, owing to the disposition of the pubescence, have an 

 annulated appearance.
