 posited in the decaying flesh, and thus 

 the young grubs, when hatched, find

We have spoken of the coleopterous 

 insects more fully than we shall of 

 those belonging to some of the other 

 orders; but not more fully than their 

 variety and importance deserve. Mr. 

 Westwood states, that the number 

 of species of this order, with which entomologists are ac- 

 quainted, cannot be less than 35,000 ; and he thinks it more 

 than probable, that when those from foreign countries shall 

 have been collected, the number will be doubled, if cot 

 trebled. The Berlin museum alone contains 28,000 species.
