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

 Academy of Natural Sciences, of Philadelphia, pertaining to the En- 

 tomology of the Americas (North and South), including Arachnida and 

 Myriopoda. Articles irrelevant to American entomology will not be noted; 

 but contributions to anatomy, physiology and embryology of insects, how- 

 ever, 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. 



All continued papers, with few exceptions, are recorded only at their 

 first installments. 



The records of papers containing new species are all grouped at the 

 end of each Order of which they treat. Unless mentioned in the title, 

 the number of the new species occurring north of Mexico is given at 

 end of title, within brackets.
