elytra are almost smooth, the few points being microscopic ; 

 the propygidium and pygidium are rather densely punc- 

 tured, the latter being very obtusely produced ; the pro- 

 sternum, keel is very short, triangular, with its margin, 

 except at the base, elevated, inner surface smooth ; the 

 mesoisternum and metasternum have a well-marked median 

 channel and are impunctate ; the anterior tibise have six 

 strong teeth, the intermediate have seven dentations, the two 

 at the tarsal end being joined at their bases. 



There is no similar species known to compare with this.

Coptotrophis trunculus, sp. n. 



Cjlindricus, piceus, nitidus ; S fronte leviter impressa 1-fcuber- 

 culata, rostro apice obtuso reflexo, $ fronte circulari concava ; 

 pronoto grosse punctate ; eljtris tenuissime puncticulatis ; pj'- 

 gidio dense punctato ; prosterno marginato ; mesostenio utrinque 

 siilcato ; tibiis anticis 6-dentatis. 



L, 21 mill. 



Cylindrical, piceous, shining, elytra, legs, and antemicC 

 obscurely brown ; ^ forehead lightly impressed with a 

 small median tubercle, ? with a circular concavity, surface 

 microscopically strigose and sparingly punctured ; the thorax, 

 anterior angles reddish, ^ slightly impressed anteriorly, ? 

 more slightly, surface very distinctly punctate, some points 

 large, others smaller, and there is a narrow median line 

 almost impunctate ; the elytra are brown and very feebly 

 punctured ; the pygidium (in both sexes) is convex, densely 

 and somewhat coarsely punctured; the prosternum is strongly- 

 margined laterally, but the striae only obscurely meet ante- 

 riorly ; the mesosternura has a well-marked lateral sulcus; 

 the metasternum has a median channel which is wide ante- 

 riorly and linear behind ; the antennae, scape has a few long 

 flavous hairs ; the anterior tibiae are 6-dentate. 



The general facies of this small species closely resembks 

 that of deyrollei, Mars., and proboscideus, ¥. Marseul says 

 of deyrollei that the mesosternal stria is ''not interrupted" ; 

 but the three species given above are exactly alike in this 

 respect, and have only a lateral sulcus. The sterna are 

 lightly and vaguely puncticulate. The relatively large size 

 of the thoracic punctures serves to separate truncidus from 

 the other two species.
