Under the above head it is intended to mention papers received at the Acad- 

 emy of Natural (Sciences of Philadelphia pertaining to the Entomology of the

 will not be noted. Contributions to the anatomy, physiqlogy and embryology 

 of insects, however, whether relating to American or exotic species, will be re- 

 corded. The numbers in HEAVY-FACED TYPE refer to the journals, as num- 

 bered in the following list, in which the papers are published ; * denotes that the 

 paper in question contains descriptions of new North American forms. Titles 

 of all articles in foreign languages are translated into English; usually such 

 articles are written in the same language as the title of the journal contain- 

 ing them, but when such articles are in other languages than English, French, 

 German or Italian, this fact is indicated in brackets.
