328 THE ENTOMOLOGIST. 



captured within the limits indicated in the title of the work. 

 Each species is described in the most ample manner ; first, the 

 name and full synonym is dealt with ; then, to assist the student 

 in making references, catch-words are pi-inted in heavier type, and 

 full desci'iptions are given of the Imago, Egg, Caterpillar, in all 

 its stages, when known ; Chrysalis, Geographical Distribution, 

 Haunts, Food-plant of Caterpillar, Habits of Caterpillar, Pupa- 

 tion, Life-history, Habits, Flight, &c., Parasites, other headings 

 when necessary ; and lastly, under the head of " Desiderata," 

 further information is sought for, if needed to complete the life- 

 history of the species. 



Tlie plates are excellent, and embrace the whole development 

 of the insect, from the egg to the imago ; in all cases the 

 explanation is given on the opposite page, a further great help to 

 the student. There are also plates of the structure and scales ; 

 and to show the geographical distribution, there are small maps 

 of the Nearctic continent, coloured to show the range of each 

 species, which may thus be understood at a glance. 



Another feature is the interpolation throughout the work of 

 essays on general subjects connected with Butterflies, such as 

 the Clothing of Caterpillars, the Eggs of Butterflies, the Modes 

 of Suspension of Clirysalids, and other interesting themes. 



The Satyrinae, which are dealt with in this first part, are 

 poorly represented in New England, even if Cercyonis alope and 

 C. nephele are treated as distinct only eight species have been 

 taken within its limits, as against eleven species, more or less 

 common in England ; on the other hand, we have but one of the 

 Papilioninse, and New England has six. Mr. Scudder remarks 

 on the former sub-famil}', that not only in New England, but that 

 in the whole of Eastern North America they are very poorly 

 represented, and form but a mere fragment of the Butterfly fauna ; 

 in Western North America they are a little more abundant, but 

 even there bear no such relation to the general fauna as they do 

 in Europe, wiiere they compose nearly one-third of t!ie whole 

 fauna, and are relatively more than four times as numerous as in 

 New England. This is a very remarkable fact, seeing that this 

 sub-family is more widely spread over the globe tlian any otlier. 



Probably no wox*k has been attempted or produced which 

 deals with the Rhopalocera of a region in such a complete 

 manner. No doubt the whole will be equal in merit to the 

 excellent first part; and the high reputation in wliich Mr. Scudder 

 is held, as an Entomologist of the first rank, will cause the 

 appearance of each successive jjart to be looked forward to with 

 eagerness. — J . J. W.
