9$ ENTOMOLOGICAL NEWS. [April, 



Entomological Literature. 



Under the above head it is intended to note such papers received at the Academy of 

 Natural Sciences of Philadelphia pertaining to the Entomology of the Americas (North 

 and South). Articles irrelevant to American entomology, unless monographs, or con- 

 taining descriptions of new genera, will not be noted. Contributions to the anatomy 

 physiology and embryology of insects, however, whether relating to American or exotic 

 species, will be recorded. The numbers in heavy-faced type refer to the journals, as 

 numbered 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 arti- 

 cles in foreign languages are translated into English ; usually such articles are written in 

 the same language as the title of the journal containing them, but when such articles are 

 in other languages than English, French, German or Italian, this fact is indicated in 

 parenthesis.
