between the impressions ; transverse impression of vertex broad, 

 shallow, hardly marked in the middle ; eyes prominent ; post- 

 ocnlar prominences moderate, much smaller than the eyes. 

 Pi'othorax short (2| x 3|mm.), rather convex, only a little 

 narrowed behind ; the sides rounded ; marginal border narrow, not 

 sinuate before the basal angles, not reaching the middle of the 

 base ; the basal angles ratlier obtuse ; the median line strongly 

 impressed, not reaching the base. Elytra oval (5 x 3| mm.), 

 convex, striate (the striae punctate) a very little narrowed to the 

 base ; the sides not at all ampliate; the dorsal striie (five on each 

 elytron) strong, those on the sides weak ; the intervals not convex. 

 Three last ventral segments with a deep broad fovea on each side, 

 not transversely impressed. Thiglis thickened in the middle ; 

 first four joints of anterior tarsi dilatate and spongiose below ; 

 middle tarsi with three first sjwngiose below (third very slightly 

 so). 



Length 11, breadth 3| mm.

This species is very distinct from all the described species 

 except P. jiygmoeus to which, in the form of the basal angles of 

 the prothorax, the foveas of the ventral segments, and the under 

 surface of the tarsi, it has an affinity. 



Promecoderus pygm^us.

This species is unknown to me ; the following is M. Putzeys' 

 description : — 



Of a shining coppery brown ; parts of the mouth, three first 

 joints of the antennae, and the tarsi testaceous, the same as the 

 extremity of the thighs. The lobes of the mentum have their 

 internal extremity pointed ; the niedian tooth is narrow and 

 pointed. The antennae are long and reach past the base of the 

 elytra ; the second and third joints are brown at the end ; the 

 pubescence begins towards the apex of the third joint. The two 

 impressions between the antennae are well marked ; the eyes are 

 lightly inclosed, and more prominent than the post-ocular 

 prominences. The prothorax is almost orbiculate, but little
