sented as shorter than in Choleva ; but the greater size of the 

 North American species, and Erichson's remark, in a note added 

 to Tellkampf's account, that it is principally the want of eyes 

 which distinguishes Adelops from Choleva, is against this suppo- 

 sition. On the other hand, new doubts and conjectures arise from 

 the information of Erichson, that the museum at Berlin possesses, 

 besides the North American Adelops, two other species, one from 

 Carniola, and the other from Sicily ; for, one cannot help thinking 

 that the species from Carniola, said to have been communicated 

 by Schmidt of Schischka, may prove to be B. montana, which is 

 frequent in that locality, and where Schmidt had often made col- 

 lections. In that case it may be suspected that Erichson was 

 prevented from closely examining the animal, either by the paucity 

 of specimens or some other cause; so that it still remains doubtful 

 as yet whether his two European species agree generically among 

 themselves, or with Adelops.

The next genus, Stagobius, is so peculiar in its structure, and 

 so unlike all the Silphce, and yet possesses nothing in its habit 

 to remind us of any other family, that we must rigorously adopt
