 be changed, and continually being changed, consequently not 

 only of minor importance, but, when carried to extremes, a 

 great evil, a hindrance to the student, an actual bar to the be- 

 ginner. It is only by the specific name that we know the insect ; 

 with this knowledge the rest is attainable. " — Herman Strecker.

 common sense and utility, and these should not be lost in the 

 abyss of caprice or conceit. 



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 he recorded. The numbers in hkavy-faced type refer to the 

 journals, as numbered in the following list, in which the papers are published ; * denotes 

 that the paper in question con tains 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 containing them, but when such articles are in 

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