218 THE CANADIAN ENTOMOLOGIST. 



cussed and approved of by Entomologists in general. We do not, how- 

 ever, wish to disparage the work ; it is certainly a valuable compendium, 

 and we cordially recommend it to our readers who are beginners in Ento- 

 mology. The book is well written and excellently illustrated throughout, 

 and must prove a great help to the science by furnishing young students, 

 in a convenient form, with information that hitherto they could not readily 

 procure. C. J. S. Bethune. 



The Butterflies of the Eastern United States and Canada, 

 with special reference to New England, by S. H. Scudder. Imp. 

 8 vo. Cambridge, pp. 1-40 and 105-208, Part I, 1st Nov., 1888. 



For some months Lepidopterists and Librarians have been anxiously 

 awaiting the appearance of Mr. Scudder's monumental work on the 

 Butterflies of New England, which, as is well known, has been constantly 

 engaging the attention of this keen observer and careful student for the 

 last 20 years. Through the courtesy of the author we have been favoured 

 with advance sheets and plates of Part I, which is to appear on 1st Nov., 

 1888. From the well known high character of Mr. Scudder's past work, 

 doubtless much will be expected by the scientific world of this long 

 promised book. Judging from the number under consideration we 

 believe few will be disappointed. No work has ever appeared, in any 

 branch of science, where such thorough and complete information is given 

 of the objects discussed, nor which has been so copiously and accurately 

 illustrated. An Introduction treats, with the greatest detail, of the general 

 structure of butterflies from the egg to the imago, and includes a chapter 

 upon their classification. This is followed by a systematic treatise in 

 which " not only every species," (embraced within the scope of the work) 

 " but also every genus, tribe, sub-family and family is described and dis- 

 " cussed with a fullness never before attempted, except in individual 

 " cases, including in each instance not merely the perfect form, but, when 

 " possible, the egg, the caterpillar at birth and in the succeeding stages, 

 " and the chrysalis, together with the distribution, life-history, habits and 

 " environments of the insect, in which a great accumulation of new facts 

 " and observations is embodied." 



In the Part before us we have pages 1 to 40 of the Introduction cover- 

 ing the structure of the egg, the caterpillar and the chrysalis, and the 

 beginning of the description of the perfect insect. There is then a break 

 and the pagination continues again at page 105, where the second section
