the first joint. Body rather stout, only moderately convex, subfusiform, 

 black throughout, the legs paleflavate; antennae infuscate, flavate at 

 tip; head moderately small in size, much narrower than the elytra, the 

 sides parallel behind the eyes for a short distance, the sides being almost 

 evenly arcuate from the eyes to the neck; punctures rather coarse and 

 close set; prothorax longer than wide, only very slightly narrower 

 than the head, parallel, the sides feebly arcuate, the punctures small, 

 rathtr feebly impressed and sparse; elytra slightly elongate, parallel, 

 not very coarsely but strongly, confusedly and closely punctate, much 

 longer at.d wider than the prothorax in both sexes; abdomen as wide 

 as the elytra or slightly wider, the sides parallel and very feebly arcuate, 

 the punctures strong and close- set, becoming coarse, scabrous and 

 sometimts subconfluent toward the sides. Male with the fifth ventral 

 unmodified, the sixtu with a deep triangular notch nearly one half 

 deeper than wide, with the angle obtusely rounded and the opening 

 abruptly formed and half as wide as the apex; female not differing 

 greatly from the male, the sixth ventral narrow, oblu.»ely rounded at tip.

Antennae rather slender and only just visibly increasing in thickness from 

 the end of the first joint to the end of the sixth, the last five joints ab- 

 ruptly much wider, forming a loose parallel club. Body fusiform, 

 moderately stout, black, the legs pale flavous, the antennae slightly 

 fuscous, gradually paler toward tip; head small, elongate as usual, 

 very much narrower than the elytra, the sides converging and evenly, 

 strongly arcuate from the well- developed but only moderately promi- 

 nent eyes to the neck, which is three-fourths as wide as the head, the 

 lateral foveolae very deep and conspicuous ; punctures coarse and close- 

 set; prothorax slightly elongate, about as wide as the head in the fe- 

 male, tbe sides parallel and feebly arcuate, sometimes broadly angulate 

 at the middle, the punctures rather small but conspicuous, somewhat 

 sparse and impressed; elytra large, somewhat longer than wide, very 

 much longer and wider than the prothorax, the punctures rather small 

 but very deep and close-set, confused; abdomen as wide as the elytra, 

 nearly as in cinctum, but less strongly sculptured. Male unknown;

 deep black, the legs and antennae flavate ; head small, distinctly elongate, 

 very much narrower than the elytra, the sides parallel and straight for 

 some distance behind the moderately large and convex eyes, then con- 

 verging and more arcuate to the neck, the punctures less coarse than 

 in cinctuni, and twice as widely separated; prothorax large, longer than 

 wide, parallel, with the sides evenly and moderately arcuate, slightly 

 wider than the head, the punctures rather coarse, deeply impressed and 

 widely separated; elytra but little longer than wide, slightly longer and 

 wider than the prothorax, the punctures rather coarse, deep and close- 

 set, confused in arrangement; abdomen about as wide as the elytra,
