550 CLASS INSECTA. 



back has a furrowed keel, terminated before in a rounded 

 and bilobed bunch. The labrum is entirely exposed, and of 

 ordinary size. The eyes are more elevated than in the other 

 pimelias. The antennas, moreover, are hairy. The elytra 

 are very unequal. 



Sepidium, Fab. 



They are found in the hot countries of Europe and Africa. 

 {Sep. tricuspidatum, variegatum, et cristatum of Fab.) 



The last pimeliae, having, like the foregoing, the mentum 

 without upper emargination, is removed from these in the 

 form of the articulations of the antennae. They are, for the 

 most part, sub-cylindrical, or in form of a reversed and elon- 

 gated cone ; the last three or four only are rounded, whether 

 ovoid, turbinated, or hemispherical. The labrum entirely 

 uncovered, and the marginal projection of the head covering 

 the origin of these organs, is but little elongated, as well as 

 in Sepidium. These insects belong to the colony of the Cape 

 of Good Hope. The eyes are nearly round or oval, entire, or 

 but little emarginated and elevated ; the corslet is depressed, 

 sometimes dilated on either side like an angle, sometimes 

 narrower, but furrowed and keeled above. The last articu- 

 lation of the antennae is obviously longer and thicker than 

 the preceding. Such are 



Trachynotus, Lat. Sepidium^ Fab.* 



In these the eyes are narrow and elongated, scarcely at all 

 elevated. The corslet is convex, nearly orbicular, emargi- 

 nated in front, truncated behind, without dilatations, lateral 

 angles or dorsal keel. The last articulation of the antennas 

 is, at most, of the size of the preceding.

 A species which the Count Dejean names Curcoloides, and figured hy 

 Degeer, forms a particular division.
