120 THE CANADIAN ENTOMOLOGflST. 



A CORRECTION. 



Dear Sir : I described in the Canadian Entomologist, June, 1885, 

 vol. xvii., p. 115, a new Ichneumonid for which I created the new genus 

 Platysoma. But advised by my friend, Mr. E. T. Cresson, I recognized 

 that this name was pre-occupied for a Coleopterous insect of the family 

 Histeridae. I propose in consequence to change this name in that of 

 Aplomerus (from aplous simple, and meros thigh). Thus, Platysoma 

 tibialis must be read Aplomerus tibialis Prov. 



Cap Rouge, April 15th, 1886. L. Provancher. 



BOOK NOTICE. 



The Butterflies of the Eastern Utiited States : By G. H. French, A, M. 



This book is indicative of the progress lately made in Zoology, and 

 particularly in Entomology, in that such work is possible, and that it is 

 appreciated. In a plain, simple, and still complete and thorough way, it 

 presents the facts known about a large and distinct group of living objects, 

 which attract the interested attention of every lover and student of nature. 

 The first question which a student asks of a newly found object is, " What is 

 it ?" If the object comes within the scope of this volume, this question 

 will be answered easily and satisfactorily. The work has been done care- 

 fully and well. The writer has shown his good judgment quite as much 

 in what he has left out, as in what he has put in his book. He has wisely 

 accepted the work which the great body of Entomologists has done before 

 him. He has not felt that a woe rested upon him if he failed to revise, 

 which commonly means to ignore all such work. He has not tried to create 

 a chaos and call it science. He has evidently preferred to present the 

 facts of his subject, rather than to display himself. For what he has done, 

 and for what he has omitted to do, he deserves thanks. The volume is 

 well printed, and its many illustrations, though in many cases familiar, are 

 still the best extant. While we recognize their abundance, we still wish 

 there were more, and hope that it will at some time be possible to figure 

 in such a book every species mentioned. We trust that this work will be 

 followed by others equally meritorious in every division of the wide Ento- 

 mological field. S. H. Peabody.
