158 Miscellaneous. 



in colour for the first time. With exceptions noticed below, every 

 species of butterfly found on the continent of North America from 

 the Gulf of Mexico to the Arctic Circle is thus illustrated. Five of 

 the earlier plates are devoted to larvae and pupa). 



There are also nearly 200 plain illustrations in the text, illustrating 

 details of the earher stages of butterflies, apparatus, neuration, &c., 

 and Megathymus yucccn. The author adds that there are about 125 

 other species, chiefly Hesperiidae, which have not been mentioned ; 

 but we may take it that these are obscure and little-known species 

 occurring in out-of-the-way parts of the country, and that, as 

 regards all the more accessible parts of North America, his book 

 may be relied upon as practically complete. We regret, however, 

 that the omitted species should not have been included in an 

 appendix, however brief — were it only a mere list of names. 



The letterpress is divided into three sections. The Introduc- 

 tion contains four chapters on the Life-histor}* and Anatomy of 

 Butterflies; the Capture, Preparation, and Preservation of Specimens; 

 the Classification of Butterflies ; and Books about North-American 

 Butterflies. 



The bulk of the book consists of descriptions (necessarily, but not 

 unduly, brief) of the Butterflies of North America north of Mexico, 

 thus covering the whole ground up to the boundaries of Messrs. 

 Godman and Salvin's ' Biologia Centrali-Americana.' The arrange- 

 ment followed is NymphaUdce (including Libytheince), Lemoniichv, 

 Lyccenidce, Papilionida' (including Pierince), and Iles^ieriidce (including 

 MegatJiymince). Scattered through the book are various digressions 

 and quotations, poetical and other. 



We hope that the author will carry out his intention of continu- 

 ing his work by a book on the Moths of North America likewise, 

 for such a work would be of still greater scientific and general 

 value than even that before us. 



Dr. Holland appears to have done his work very well, and we 

 hope that it will also be appreciated on this side of the Atlantic, 

 for there are surely many British and European entomologists who 

 will be glad of an opportunity of making themselves acquainted 

 with a fauna which presents such a remarkable resemblance to 

 our own ; though, apart from the presence of some purely American 

 or representative forms, the proportion which the number of species 

 of the various groups bears to each other in Europe and North 

 America is often strangely different ; for example, the Satyrince, 

 which form the bulk of the middle-sized butterflies in Europe, are 

 very poorly represented in North America.
