Entomological Literature. 



COMPILED BY P. P. CALVERT. 



Under the above head it is intended to mention 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 will not be noted. Contribu- 

 tions to the anatomy, physiology and embryology of insects, however, relating to Ameri- 

 can 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 

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

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

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