part in Flint and Malloch's figure 42. It does not in any way corres- 

 pond to the similar part, drawn, obviously to correspond, in their figure 

 41 of penitalis. The aedoeagus in all three species (nubilalis, penitalis, 

 and ainslici) is strikingly similar; but penitalis of the three, alone 

 possesses a stout spur arising ventrally to this organ from the base of 

 the anellus and this the authors have figured as corresponding to the 

 aedoeagus in ainsliei.

Entomological Literature 



COMPILED BY E. T. CRESSON, JR., AND J. A. G. REHN. 



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, 

 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 all grouped at the end of each Order of which they treat.

 tomology, Series A, London. For records of papers on Medical Ento- 

 mology, see Review of Applied Entomology, Series B.
