Narrowly rhom))oid-oval, convex, black, the tibi:* and antennae 

 rufo-piceous ; vestiture white, consisting- of long, very slender, not 

 very densely but uniformly distributed squamules on the upper 

 surface, which are replaced, however, by black squamules in two 

 broad transverse elytral bands, interrupted at the suture, one at the 

 middle and the other near the apex ; on the under surface the scales 

 are elongate, but broader and denser. Head alutaceous, finely but 

 strongly, sparsely punctured, glabrous, with the exception of a line 

 of very minute squamules along the edge of the eyes; impression 

 very broad and almost obsolete, with a small feeble median fovea; 

 lieak abruptly polished, slender, feebly but almost evenly arcuate, 

 gradually slightly thicker aTid more arcuate at the base, sparsely 

 punctured and squamulose at the sides near the base but elsewhere 

 very minutely, sparsely punctate and glabrous, not at all dilated at 

 the antennae but gradually wider and flatter toward apex, about 

 two-thirds as long as the body; antennge inserted just beyond basal 

 third, slender, the scape extending almost to the eye, the first funic- 

 ular joint slender, clavate, as long as the next two, second slender 

 and as long as the third and fourth, outer joints slightly thicker and 

 nearly as wide as long, club rather small and narrow, oval, pointed. 

 Prothorax barely one-third wider than long, the sides evenly, broadly 

 arcuate, convergent anteriorly, becoming broadly sinuate behind the 

 apex and almost parallel near the base, the latter transverse, the lobe 

 less than one-third the width but strongly rounded and very promi- 

 nent; apex truncate and distinctly more than one-half as wide as 

 the base ; disk dull, not very coarsely, extremely closely and poly- 

 gonally punctate, the impunctate line not distinct. Scutellum well 

 developed, quadrate, slightly wider and transverse behind, the angles 

 acute; surface flat, moderately densely squamulose. Elytra dis- 

 tinctly wider and three-fourths longer than the prothorax, the sides 

 very strongly convergent, broadly, feebly arcuate, the apex narrowly 

 rounded ; humeral callus very prominent ; disk rather finely .striate, 

 the intervals wide, somewhat dull, finely, rather sparsely, confusedly 

 and slightly rugosely punctate throughout. Prosternum flat and 

 separating the coxae by fully three-fourths of their own width, but 

 strongly constricted laterally behind the apex, and with a tran.s-
