Eyes parallel on the lower side. Ocelli in a triangle ; the hinder ocelli separated from 

 the eyes by the length of the third antennal joint, and from each other by a little more 

 than the length of the fourth. Clypeus but slightly convex ; the apex distinctly and 

 completely margined, broadly roundly projecting, flat. Head rugosely punctured; a 

 shining, impunctate space on the vertex near the top ; the clypeus and face with 

 scattered punctures ; antennal tubercle flat ; the face and oral region, the orbits 

 broadly to the top of the antennal tubercle, and the greater part of the mandibles, 

 yellow; a small quadrate spot between (and above) the antennae, and an obscure 

 fulvous spot behind the eyes. Antennae short, stout, perceptibly thickened towards 

 the apex ; the scape yellow ; the flagellum more or less fulvous beneath ; the third 

 joint thinner than the fourth (especially at the base), and nearly twice its length. The 

 hair on the head is longish, moderately thick, and silvery-white. Thorax shining ;

 punctured; the median segment closely transversely punctured $ the triangular area 

 punctured at the base and along the sides, the rest shining and impunctate, and with 

 a wide furrow in the middle, which does not reach much beyond the base of the 

 impunctate part. Median segment and pleurae covered with short, soft, pale hair ; the 

 median segment roundly curved. Prosternum elongate, placed much lower than the 

 top of the pronotum. Abdomen shining, almost glabrous at the base, covered with 

 large, deep, widely separated punctures. Pygidial area subtriangular, smooth, shining, 

 sparsely punctured ; laterally indistinctly keeled. A line on the pronotum, the tegulae 

 in front, the metanotum, a broad belt on the base of the second segment, a narrow one
