Long. 3 lin. 
Hab. Guatemata, Capetillo (Champion: var. A); Panama, Volean de Chiriqui 
(Champion : type). 
Head smooth, impunctate. Antenne filiform ; first and second joints short, submo- 
niliform ; third joint longer than the preceding two united, obsoletely compressed ; club 
not thicker than the preceding joints, attenuated towards itsapex. Thorax nearly half 
as broad again as long; sides straight and nearly parallel from the base to beyond the 
middle, thence obliquely converging to the apex, the anterior angle armed with a short 
subacute tooth; upper surface rugose-punctate, the medial line with a fine longitudinal 
groove; the extreme lateral margin, together with a discoidal vitta, black. Scutellum 
black. Elytra subelongate, parallel, very slightly dilated towards the posterior angle, 
rounded at the apex, distinctly emarginate at the suture ; finely serrulate, the serratures 
rather more distinct on the apical margin; each elytron with eight regular rows of 
punctures, all the interspaces, from the first to the sixth, slightly prominent, but not 
distinctly costate. | 
This species may be separated from its allies by the non-costate elytra.

Interocular space rather strongly produced ; vertex impressed on the medial line 
with a faint longitudinal groove ; front finely carinate. Antenne more than half the 
length of the body, strongly compressed, attenuated towards the apex; the third to 
the seventh joints cristate; two lower joints short, cylindrical. Thorax not broader 
than long in the male, rather more transverse in the female; sides nearly straight and 
parallel at the base, thence slightly converging and slightly rounded to the apex; 
upper surface transversely convex, broadly and distinctly excavated on the hinder disc, 
closely punctured. -Elytra subparallel, very slightly increasing in width from the base 
towards the apex; the latter rounded, broadly emarginate at the sutural angle; outer 
margin finely serrulate; each elytron with eight regular rows of punctures; the second,
