32 PROSOPOCOELUS PASTEURI. 



crenulate; the extremely fine and dense sculpturing of the 

 mandibles is intermixed with very distinct punctures. 



The head is square , slightly narrower than the front 

 of the thorax , declivous and unevenly depressed on the 

 frontal half; the front edge is semicircularly emarginate 

 and almost perpendicularly sinking towards the clypeus, 

 which latter is broadly trapezoidal and has on the middle 

 of its front margin a small , rounded projection ; the late- 

 ral front angles of the head are obliquely truncate, the 

 canthus is narrow, faintly emarginate in the middle and 

 extends as far as the middle of the eye ; in front of the 

 thoracical angles the head is slightly swollen ; the surface 

 is very densely covered with extremely fine gi-anulations. 



The prothorax is somewhat broader at the base than in 

 front, and strongly convex along the middle; the sides 

 are straight, the front angles protruding and rounded, 

 the hind angles very broadly rounded and their hind mar- 

 gin turned upwards ; the front margin of the prothorax is 

 deeply bisinuate , the hind margin faintly so ; the sculptu- 

 ring agrees with that of the head. The scutellum is large 

 and slightly transverse , its surface coriaceous , without 

 distinct puntures. 



The elytra are coriaceous and densely covered with extre- 

 mely fine punctures. 



The intercoxal part of the prosternum is conically pro- 

 longed backwards. The femora and tibiae, as well as the 

 under surface of the insect are opaque, with the exception 

 however of a large triangular spot on the metasternum 

 posteriorly and of the abdomen which are subshining ; the 

 latter is sparingly and finely punctate , its apical segment 

 more strongly so. 



The outer edge of the front tibiae is irregularly crenu- 

 late , some of the crenulations dentiform ; the middle and 

 hind tibiae unarmed.
