become half grown. The insect has but one brood in the year. Mr. 

 Edwards also remarked that Lycaefia violacea feeds upon many different 

 food plants. 



The meetings of the Entomological Sub-section were throughout very 

 interesting and profitable, and the " brethren of the net " separated with 

 regret, the hope being expressed by all that they might be privileged to 

 meet again next year in Montreal.

Butterflies : Their Structure, Changes and Life Histories. By Samuel H, Scudder. 

 We are indebted to the author for a copy of this beautiful book, a 

 well printed octavo volume of 322 pp., illustrated with 201 figures. The 

 work is divided into thirteen chapters, the first six of which treat of the 

 structure of butterflies in all the stages of their growth from the egg to the 

 perfect insect. A chapter is devoted to the internal organs of caterpillars 

 and another to the transformation of these organs during growth. The 

 remaining chapters deal with the life histories of these attractive msects 

 and the changes which they undergo under varying cii^'^umstances. 

 Following these is an appendix containing instructions for collecting and 

 preserving insects, etc., a list of the common and scientific names of 

 butterflies, and a list also of the food plants of their caterpillars, all written 

 in a plain and popular style. It is a great pity that a work ot this char- 

 acter, coming from so well known and talented an author, and containing 

 as it does so much useful and valuable information, should be marred by 

 the introduction of a series of new names for our butterflies which to the 

 great bulk of the Entomologists of America seems to be a most unreason- 

 able imposition and against which their is a general feeling of revolt. 

 That any author should persist in carrying the rules of priority so far as to 

 resurrect old documents the authority of which is of the most questionable 

 value, and on the strength of these insist on the changing of nearly all the 

 names of our butterflies, is a tax on the patience of the practical man 

 which few can endure, and a serious bar to the progress of our favorite 

 science. Neither do we think that the introduction of a large number of 

 newly invented common names will add in any degree to the popularity 

 of Entomology ; it were far better, in our opinion (with few exceptions), 

 to use the specific name of the insect for this purpose, which is as easily 

 learnt and conveys a more definite idea than is possible with such com- 

 mon names as those given by this author.
