Entomological Ivitera.tu.re. 



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

 Natural Sciences of Philadelphia pertaining to the Entomology of the Americas (North 

 and South). Articles irrelevant to Amerjcan entomology, unless monographs, or con- 

 taining descriptions of new genera, will not be noted. Contributions to the anatomy of 

 insects, however, whether relating to American or exotic species will be recorded. 



1. The Butterflies of North America by W. H. Edwards. Third 

 series, partxvii. Boston: Houghton, Mifflin & Co., 1897. — Contains figures 

 and descriptions of various species of Chionobas, one of them {peartice) 

 being new to science. The three plates in this number are superb exam- 

 ples of what such illustrations should be, and are of great scientific value^ 

 especially the figures representing the various larval stages of a number 

 of the species treated. This number alone contributes much that is new 

 in regard to life-histories, especially as so little has hitherto been known 

 of the early stages of the species in the genus. The part completes vol- 

 ume three of this truly representative work, and we sincerely hope the 

 work will not end here. We have absolutely nothing but praise for such 

 a work, but have sometimes been disappointed on account of its fragmen- 

 tary character, probably unavoidable. Very often the species one wants 

 to know about is not treated, and there is great need of a work in this 

 country covering all the species in each genus, or at least contributions 

 toward it. Mr. Edwards has probably more nearly approached this re- 

 sult in Chionobas. If the work is continued, it seems to us the most im- 

 portant thing the author could do would be to give figures of his own 

 species not hitherto illustrated, especially in the genus Argynnis. — H. S. 



2. British and European Butterflies and Moths. By A. W. 

 Kappel and W. Egmont Kirby. This is a quarto volume of 247 pages 

 and 30 chromo-lithographic plates contaimng many figures. The plates 

 are good illustrations of the process and are quite satisfactory and answer 

 well for purposes of identification. The work does not include all the 

 European species, but most of those inhabiting central Europe have been 

 dealt with, and nearly all those of the British Isles. There is an intro- 

 duction treating of structure, collecting and technique. The work will be 

 found a very useful one, especially for the beginner. — H. S. 



3. British Butterflies, being a popular hand-book for young stu- 

 dents and collectors. By J. W. Tutt; octavo 465 pages and nine plates. 

 — This is an up-to-date work and contains the recent and generally-ac- 

 cepted schemes of classification. The general chapters on the "Egg,"" 

 "Caterpillar," "Chrysalis" and "Imago" will give the young student 

 the clues he requires to follow up the more advanced branches of the 

 study. There are chapters on "Variation" and " Hybernation" as well 

 as notes on the senses of butterflies. This is one of the best new books 

 on an entomological subject we have lately seen, and its talented author 

 is to be greatly congratulated. The chapters on the practical work of, 

 and apparatus for, collecting, killing, setting and preserving insects are
