that any one who has studied Hiibner's work should have failed to recognise the 

 importance of supplying the deficiency. 



It must also be pointed out that where new generic names have been substituted 

 for old ones pre-occupied, as in the case of Scoliaula for Bohemannia, " n. n." should 

 haye been used instead of " n. g.," and as an unnecessary addition to generic 

 nomenclature, it may be mentioned that Ischnoscia, n. g., for subtilella, was 

 anticipated by Milliere, who, in 1874, created for it the genus Ouenea, and whose 

 specific name borreonella also precedes subtilella Fuchs. Tortrix bifasciana, Hb., 

 will repay further study, and should be retained as the type of Chrosls, Grn. {nee 

 Meyr.). In spite of these criticisms, the generic divisions which the author has 

 marked out are distinctly well-founded, the selection of names being the only point 

 in which we are seriously at issue with the author. In any case the book can be 

 safely and strongly recommended as the best and most instructive work dealing 

 with the increasingly popular study of the Lepidoptera that has appeared up to the 

 present time, and affords additional proof of that unflagging industry and high 

 ability which practically created the catalogue of the Micro- Lepidoptera of Australia 

 and New Zealand. — Walsingham. 



The Book of British Hawk Moths : by W. J. Lucas, B.A. Pp. 156, 12mo. 

 London : L. Upcott Qill. 1895. 



Tliis is a handy little book, excellently printed on good paper, and with capital 

 illustrations (nearly all original), each species, with one or two exceptions, having a 

 plate devoted to itself. The text as a whole is reliable, the author having laid 

 already existing publications largely under contribution, and in the case of the rarer 

 species the list of occurrences and localities is fairly complete, though we note some 

 conspicuous omissions. 



Feail Children of the Air ; excursions into the world of Butter- 

 flies : by Samuel Hubbard Scudder. Pp. 279, 12mo. Boston and New York : 

 Houghton, Mifflin and Co. 1895. 



The only bad feature about this instructive little volume is its primary title, 

 which, from the cover only, led us to imagine its amiable author had taken to novel 

 writing. It is a collection of papers selected for the general reader from the author's 

 large and somewhat costly work on the Butterflies of the Eastern United States, 

 amended to bring them down to date, and in some cases replying to criticisms and 

 objections. There are nine chapters in all, on very varied subjects, each of which is 

 full of information, and written in a charming style : we heartily commend the book 

 to the notice of our readers.

 Pt. XVI. 4to. Boston and New York : Houghton, Mifflin and Co. 1895. 



This part is occupied by Parnassius Smintheus and its var. Hermodur, Satyrus 

 Charon and its var. silvestris, and Chionobas gigas and an unnamed var., all worked 

 out in the greatest possible detail, and the plates are, as usual, inimitable specimens 

 of iconographic excellency. Twenty-seven years have elapsed since this magnificent 

 work was commenced, and all along it has been a continuous tribute to the author's 

 singleness of purpose.
