ocular space moderately produced, angulate. Antenne black, more than a third the 
length of the body, thickened towards the apex ; joints cylindrical. ‘Thorax transverse ; 
sides converging from base to apex, obtusely rounded, the anterior angle produced into an 
obtuse tooth; upper surface transversely convex, the hinder disc transversely depressed, 
coarsely and closely punctured ; disc with three black vitte, extending from the base to 
the apex. Elytra broader than the thorax; sides parallel, rather quickly dilated at the 
hinder angle, serrulate; posterior angle dilated laterally into an acute triangular plate ; 
apex obtusely rounded; apical margin, together with the hinder margin of the dilated 
posterior angle, more strongly serrulate than the sides; each elytron with ten, at the 
extreme base with eleven, rows of. large deeply impressed punctures; the second, fourth, 
and eighth interspaces, together with the base and apex of the sixth, costate ; aneous, 
variegated with fulvous markings, which. form an irregular semicircular band extending 
from the middle of the basal margin to the suture just before its middle, an irregular | 
fascia just below the middle of the elytron, and a transverse patch or fascia immediately 
_above the apex: these markings vary greatly in extent, and in some specimens the 
apical margin is also fulvous.

Hab. Mexico (Sallé). A single specimen. 
Head moderately produced between the eyes; front impressed on the medial line with 
a shallow longitudinal groove. Antenne slender at the base, thickened towards the 
apex, rather more than a third the length of the body; joints cylindrical, the basal 
one short, the second about one half longer than the first, rather shorter than the third, 
and about equal inlength to the fourth. Thorax nearly twice as broad as long; sides 
nearly straight and parallel at the base, rounded and dilated in the middle, converging 
at the apex, the anterior angle armed with a stout subacute tooth ; transversely convex ; 
surface unequal, transversely excavated on either side just before the base; velvety, 
nearly impunctate on the sides, impressed on the middle disc with a few large piceous 
punctures; lateral] margin and base stained with nigro-piceous. Scutellum piceous. 
Elytra much broader than the thorax; sides gradually dilated from the middle to the 
posterior angle, the latter produced laterally into a triangular plate; apical margin
