to our favourite science, the greatly increased degree of general at- 

 tention with which it is now regarded. 



I propose dividing Tragocerus into two sections, viz. 



a. Elytris apice bidentatis. 



/3. Elytris apice rotmidatis, 



Tliese characters, however, it is to be observed, may hereafter be 

 ascertained to be sexual instead of sectional. 



To the former section belong, 



1. bide7itatus, Don. 



2. Spencii, Hope. 



3. flavicomus, Hope. (Sp. nov.) 



4. Lepidopterus , Schreibers. 

 To the latter belong, 



5. fasciatus, Don. 



G. sulplmrifer, Hope.
