7G Mr. G . Lewis on 



elytra are almost smooth, the few points being microscopic; 

 tlie propygidiuin 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 

 nieso>ternum and metasternum have a well-marked median 

 channel and are impunctate ; the anterior tibiae 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.

Coptutrophis trunculus, sp. n. 



Cylindricua, piccus, nitidus ; S fronte Icviter impressa 1-tuber- 

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

 pronoto grosso punctato ; elytris tenviissime puncticulatis ; py- 

 gidio dense punctato ; prosterno marginato ; mesosteruo utriiique 

 sulcato; tibiis anticis G-denlatis. 



L. 2i mill. 



Cylindrical, piceous, shining, elytra, legs, and antenna; 

 obscurely brown ; ^ forehead lightly impressed with a 

 small median tubercle, ? Avith 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 

 ])uncture(l ; the pygidium (in both sexes) is convex, densely 

 and somewhat coarsely punctured; the prosteruum is strongly 

 margined laterally, but the stride only obscurely meet ante- 

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

 the metasternum has a median channel which is wide ante- 

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

 Havous hairs ; the anterior tibiaj are G-dentate. 



The general facies of this small species closely rescmbhs 

 that of deyroUei, INIars., and proboscideus, F. Marseul says 

 of deijrollei that the mcsosternal 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 punctieulate. The relatively large size 

 of the thoracic ])unctures serves to separate Intnculus from 

 the other two species.
