the gense but angular close to them, acuminate laterally and pro- 

 duced on each side of the deep, broad, apical impression into two long, 

 sharp, triangular teeth which are carinate longitudinally in the median 

 part, vertex with a carina arcuate towards the base and more raised, 

 even sub-tuberculiform there, in which case the lateral part of the 

 carina is obliterated, basal part of the head punctate instead of 

 being scrobiculate ; prothorax obtusely rounded at the anterior 

 angles, distinctly sinuate from there to a short distance from the 

 median part, and gradually but slightly ampliated from there to 

 the rounded, basal angle, the outer margin is somewhat broadly 

 marginate ; prothorax retuse for a little less than half the width, 

 very slightly impressed on each side of the middle of the retuse part 

 which has at apex two median truncate slightly overhanging 

 tubercles, sometimes truncate at tip and continued as a short 

 carina, curving backwards, the whole surface is very closely and 

 moderately punctulate, the punctures on the sides are rugose ; 

 elytra deeply sinuate laterally past the shoulders, covered with 

 closely set, nearly confluent, moderately deep punctures, striae very 

 fine and hardly punctulate ; pygidium very closely punctate ; meta- 

 sternum smooth in the median part, and with a distinct, longitudinal 

 impressed line for nearly all the length ; apical spur of anterior 

 tibiae, bent at right angles. 



Length 10^-14 mm. ; width 7-9 mm.

Black, opaque ; head scrobiculato-punctate, except on the vertex 

 which is covered with closely set, deep punctures, genae sub- 

 diagonal, but in a line with the clypeus, very broadly incised, and 

 with the two apical teeth carinate longitudinally in the middle, the 

 suture of the genae is continued transversely for a very short distance 

 in the frontal part ; prothorax sloping in front for two-thirds of the 

 length, broadly impressed on each side of the sloping part which is 

 distinctly carinate, the carina being emarginate in the centre, the 

 discoidal part is nearly vertical on each side, the lateral carinate 

 part overhanging a little the lateral basal part, and also the lateral 

 fossa, the outer sides are slightly ampliate laterally and very slightly 

 sinuate near the anterior angle only, but in the small development 

 the outer margin is more rounded at middle, the whole surface is 

 covered with very closely set, deep, round punctures, turning to
