Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Head smooth and shining; face armed between the antenne with an acute tooth. 
Antenne rather longer than the head and thorax, distinctly thickened towards the 
apex, the joints cylindrical. Thorax rather broader than long; sides obtusely rounded, 
obsoletely angulate immediately behind and again just before the middle, straight and 
slightly diverging at the base, converging from the middle to the apex, apical angle 
not produced, obtuse; upper surface convex, smooth and shining, impressed on the 
sides and hinder disc with large deep punctures. Elytra oblong, subparallel, regularly 
rounded at the apex; strongly punctate-striate, the strice (nine at the extreme base 
and eight on the rest of the surface) arranged in double rows; alternate interspaces 
slightly elevated, the second and fourth from the suture more strongly thickened, 
costate. 
The present insect differs entirely in the coloration of its thorax from any hitherto 
described species of the genus.
