name shall be applied to more than one genus io any branch of Natural 

 History, and hence Hiibner's name for these Sphinges will have to be 

 dropped, while we return to the more familiar appellation Darapsa. The 

 present rules of nomenclature are highly unsatisfactory and occasion natural- 

 ists an immense amount of useless labour ; we do hope that something may 

 be done at the next meeting of the American Association to improve 

 matters.— Ed. Can. Ent. 



Papilio Machaon in British America. — I do not know whether 

 the Canadian Entomologists are awai'e that P. machaon is found in British 

 America. Some years ago I received several taken by Mr. Drexler at Ru-

NEW ENTOMOLOGICAL WORKS. 

 A Guide to the Study of Insects, and a Treatise on those Injurious and 

 Beneficial to Crops. — For the use of Colleges, Farm-schools, and Agri- 

 culturists. By A. S. Packard, jun., M.D., Salem : Press of the Essex 

 Institute. Parts 1 and 2, 1868. Price 50 cents each. 

 This new work by Dr. Packard supplies collectors and students of insects 

 in America with what they have long searched for in vain — a thoroughly 

 good, reliable, well-illustrated manual of structural and systematic Entomo- 

 logy, prepared by one who is a master in the science. We most strongly 

 recommend all our readers to become subscribers to this work, and we assure 

 them that they will find in it an abundant fund of interest and instruction. 

 The two parts already issued contain clear and concise descriptions of the 

 anatomy, transformations, geographical and geological distribution, diseases, 

 &c. of insects; directions for collecting and preserving specimens; a list of 

 works on Entomology; tables of classification; and the beginning of a 

 systematic account of the order Hymenoptera. They are illustrated by 78 

 well-executed wood-cuts and two full-page plates; each part consisting of 

 about 64 clearly printed pages. The work is to be completed in 8 or 12 

 parts, issued at short intervals ; the author particularly desires that subscrib- 

 ers would remit for eight parts at once ($4 in U. S. currency), and thus 

 materially assist the publishers in getting out the work. 

 The Butterflies op North America : with colored drawings and descrip- 

 tions. By Wra. H. Edwards. Philadelphia : the American Entomological 

 Society. Part 1, April, 1868. Price $2. 



It would be difficult indeed to produce anything more beautiful or true to 

 nature than these exquisite drawings of Butterflies ; they vie in excellence 

 with any European work that we have seen. Mr. Edwards, we understand,
