with evenly scattered elongate or aciculate punctures ; the 

 me303ternum sculptured like the prosternum, but the punc- 

 tures arc all aciculate, arched anteriorly, very feebly sinuous 

 on eith<>r side, sulcate on either side, but with no marginal 

 stria anteriorly ; the nietasternum furrowed in the middle, 

 punctures aciculate near the furrow, oval nearer the sides, 

 margined along the base ; the abdominal segments iiave 

 round punctures somewhat closely set ; the anterior tibia? 

 5-dentate.

Trypohius pinguisj sp. n. 



Elongatus, cyliiidricus, niger, nitidus ; capite convexo, clypco bi- 

 sinuato ; pronoto pone oculos depresso, stria lateral! valida ; 

 prosterno margine (basi excepta) subelevato ; mesosterno utriuque 

 sulcato. 



L. 4^ mill. 



Elongate, cylindrical, robust, black, shining; the head, 

 face convex, very polished, clypeus apically bisinuous, surface 

 with small scattered punctures, and one large puncture on the 

 vertex between the eyes ; the thorax, lat(n*al stria very strong 

 and markedly sinuous, terminating at the anterior angle, 

 behind the eye there is a distinct depression, surface distinctly 

 punctured but not very densely, there is no median line ; the 

 elytra with a narrow smooth basal margin, punctured like 

 the thorax, and so also are the propygidium and pygidium ; 

 the prosternum slightly incised at the base, parallel at the 

 sides, lateral stria deep and straight and continued along the 

 anterior margin, feebly punctulate, margin (except at the 

 base) somewhat raised ; tiie mesosternum obtusely acuminate 

 in front, broadly sulcate on either side, the punctures and 

 those of the metaslernum are not so thickly set as the dorsal 

 ones, the metasternura has a median channel ; the anterior 

 tibiae are 5-deutate. 



All the known species of this genus have a single notable 

 puncture on the vertex of the head.
