Manual of North American Butterfhes, by C. J. Maynard (De 

 Wolfe, Fiske & Co., Boston, 1891). This work brings together for the 

 first time descriptions of all the butterflies which occur in America North 

 of Me.xico. The literature on Lepidoptera is so scattered that only those 

 who have access to large natural history libraries, or are happy enough 

 to own an extensive library of their own, can hope to identify their speci- 

 mens for themselves, and this book is intended for those who do not have 

 these facilities. All the species listed by Mr. W. H. Edwards in his cata- 

 logue of 1884 are described, and some of those described since are noted 

 in an appendix. There are ten colored plates with about sixty figures and 

 numerous wood-cuts of about two hundred and fifty species illustrating 

 some peculiar character by which the insect may be known. The scheme 

 of the work is a very good one, and it can't fail to be useful, although 

 there are certain faults. Comparative descriptions are only of value when 

 specimens are at hand, and it would be exceedingly difficult to identify 

 from many of the descriptions without a large amount of material, which 

 the beginner does not have. A number of errors have crept in, the most 

 noticeable of which is on plate 5, fig. i, which represents the underside 

 of Synchlce janais of Drury and not adjutrix.
