Head not longer than broad ; clypeal ridge ill-defined : antenna) 

 filiform, rather shorter than the body, the second joint short, the 

 third rather longer, the fourth slightly longer than the preceding 

 two united ; the three lower, together with the tenth joints fulvo- 

 piceous (the eleventh joint broken off). Thorax scarcely broader 

 than long ; sides rounded anteriorly, sinuate behind the middle, 

 convex ; the hinder disk slightly but distinctly excavated. Elytra 

 narrowly oblong, slightly dilated posteriorly, convex, strongly 

 plicate below the humeral callus, very minutely punctured ; the 

 sutural vitta in this species terminates at the commencement of 

 the middle third of the elytron, whilst the sublateral one extends 

 to the lower end of the latter.

Head triangular ; longitudinal ridge on clypeus ill-defined ; 

 antenna filiform, nearly equal to the body in length, the second 

 and thii'd joints short, equal in length, the fourth much longer than 

 the preceding two united. Thorax slightly broader than long; 

 sides very slightly produced and rounded anterioi'ly, parallel and 

 very faintly sinuate ffom the base to beyond the middle ; hinder 

 disk excavated, obsoletely trifoveolate. Elytra narrowly oblong, 

 very slightly dilated posteriorly, finely and rather closely punctured, 

 distinctly plicate on the sides, the subhumeral costa well-defined 

 and extending below the middle of the elytron. 



Ericlison places this species in the division with the 

 thorax bifoveolate ; in the specimen before me the foveas
