naming the genera and t lie species, 

 most of the larger beetles may be 

 readily identified by the aid of other 

 collections. But there are some genera 

 in which the marks, that distinguish 

 the different species (Bcmbidium, for 

 example) are so slight, that even prom- 

 inent collectors do not attempt to name 

 them unaided. In such cases the only 

 way is to send a box of them to the 



Entomological Department in Wash- 

 ington and have them identified. 



Every unidentified beetle in the col- 

 lection should be labelled with date 

 and locality, as without such informa- 

 tion it is sometimes impossible to 

 learn the proper name. 



Beetles, like other insects, have to 

 pass through three stages (egg, larva, 

 pupa) before they become adults.
