Dark lirown, almost piceous red on the head and prothorax, dark 

 chestnut on the elytra, and with the under side and legs hghter 

 chestnut-hrown ; antennae almost brown ; head roughly punctured 

 except for a narrow, basal margin, the clypeus is not dentate in 

 front, the frontal carinate line is obliterated, and instead of a clypeal 

 carina there is on each side of the median part of the head a sharp, 

 triangular tubercle ; prothorax covered with moderately closely set 

 punctures, a little denser and slightly more rugose and also a little 

 broader in the anterior part which is slightly retuse and bears at a 

 short distance from the anterior margin two small, coalescing 

 tubercles ; scutellum with an indistinct arcuate transverse series 

 of punctures ; elytra not broader than the pi'othorax at the base, 

 nearly parallel for one-third of the length, and a little ampliated from 

 there to the rounded posterior part, convex at a short distance from 

 the base and having one juxta-sutural, entire, impunctate stria, and 

 three dorsal geminate ones hardly impressed but filled with not 

 ■closely set, round, scar-like punctures, the intervals are filled with 

 ■similar punctures a little more closely set than those in the dorsal 

 striaj, and there is a distinct callus on the posterior part at the 

 junction of the first and third dorsal striae and under the second ; 

 propygidium covered with closely set asperous granules, changing 

 into fine transverse undivided folds in the median part ; pygidium 

 smooth in the convex part, rugulose on the sides and along the 

 base, fold of pygidium very narrow in the male and carinate, 

 anterior tibiae strongly and sharply quadri-dentate ; abdominal seg- 

 ments with a lateral row of crenulate setigerous pits ; metathorax 

 with a deep, median impression and a longitudinal impressed line,
