The characters separating Clierms from Poh/phrades 

 are very slight. M. Lacordaire difi'erentiates them in 

 his tabular arrangement by the scape freel}' attaining the 

 prothorax in the former, while it scarcely reaches it in 

 the latter; he also relies upon Polyphrades being very 

 different in "fades" from C/terrus. The species here de- 

 scribed has, however, exactly the habit of Polyphrades 

 poganus, Fahr., while it has the antennas, the more 

 strongly carinate rostrum, the scrobes running out 

 more beneath the eyes, and the larger size, of C/ierrus. 

 The large prominent eyes, and the absence of ocular 

 lobes, are at variance with the descriptions of Schonherr 

 and Lacordaire, and therefore it might probably be de- 

 sirable to differentiate it generically. It is sometimes, 

 however, a question how far modifications of structure 

 with conceivable intei'mediate limits will justify generic 

 separation, and this is a case in point.
