larvae of Brachiopods into adult Brachiopods ; that of the tadpoles of 

 Ascidians into Ascidians, of Ammocetes into Lampreys, of Lepto- 

 cephalus into Conger eels, of symmetrical into asymmetrical Pleuro- 

 ncctcs, of the tadpoles of Batrachians into salamanders, frogs and 

 toads. [Translated from his Traitc dc Zooloyic, pp. 194-5.] 



This general use of larva for all groups of animals in which 

 a similar stage obtains is decidedly convenient, some such 

 term being a necessity. We notice that the latest text-book 

 of Entomology. Prof. Lochhead's Class Book of Economic 

 Entomology, uses larva in this wide sense. The subject is 

 on'e which might well be discussed by the Entomological So- 

 ciety of America at its next meeting. 



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 re- 

 corded. 



The numbers in Heavy- Faced Type refer to the journals, as numbered 

 in the following list, in which the papers are published. 



All continued papeis, 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.
