 Sciences, of Philadelphia, pertaining to the Entomology of the Americas (North and 

 South), including Arachnida and Myriopoda. Articles irrelevant to American ento- 

 mology will not be noted; but contributions to 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. 



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



The records of papers containing new genera or species occurring north of Mexico are
