Vertex trisulcate; interocular space strongly produced, a small patch on its anterior 
surface rufo-fulvous. Antenne filiform, nearly half the length of the body, the third 
joint nearly equal in length to the preceding two united. Thorax transverse, conic ; 
sides obtusely angulate, bisinuate ; transversely convex, flattened and transvetsely exca- 
vated'on the hinder disc, coarsely and irregularly punctured, a smooth torulose vitta 
on either side rufo-fulvous. Elytra elongate-ovate, slightly dilated posteriorly; apices 
conjointly subacutely rounded, the apical limb distinctly dilated, broadly and deeply 
subquadrate-emarginate at the suture, its outer edge strongly dentate, the lateral 
margin serrulate; each elytron with ten, at the extreme base with eleven, rows of 
punctures, the interstices between the punctures nearly plane; the second interspace 
strongly, the eighth moderately, costate, the basal portion of the sixth interspace also 
slightly elevated; at the base of each elytron is a rufo-fulvous patch, which varies 
greatly in size, in some specimens being confined to a small spot, in others (var. A) 
covering nearly the whole of the anterior half of the elytron.

Long. 4 lin. 
Hab. Mexico, Yolotepec (Sallé). 
Vertex trisulcate; interocular space strongly produced. Antenne about one third 
the length of the body, filiform, slightly thickened towards the apex ; joints cylindrical, 
the third to the fifth very slightly compressed ; two lower joints short, equal, the third 
rather longer than the preceding two united. Thorax transverse ; sides converging 
from the base to the apex, bisinuate ; upper surface transversely convex, rather deeply 
excavated transversely on the hinder disc, coarsely and closely, but not very deeply,
