with A. erippus, Cram., the two butterflies belonging to different 

 subfamilies of the Nymphalidae. 



It is interesting to note that Mr. Hudson thinks the well-known 

 "vegetating caterpillar "' of New Zealand will prove to be that of 

 Porina Mairi, Buller, and not of Hepialus virescens, Doubl. (We 

 cannot UTiderstand why Mr. Meyrick and Mr, Hudson should con- 

 tinue to place an insect so dissimilar from the European types of 

 Hepialus in the saoae genus.) Mr. Hudson has already pointed out 

 (' Entomologist,' xviii. p. 36) that the larva of "//." virescens lives 

 in the stems of trees, and never goes beneath the ground even to 

 pupate ; and in the present work he remarks ; — " The real point to 

 be discovered is the precise species of Lepidoptera this caterpillar 

 would develop into it' not attacked by the fungus ; but at present 

 no definite information has been obtained on the subject." We do 

 not remember that very much has been published on the " Vege- 

 tating Caterjjillar " of late years, and we are sorry that Mr. Hudson 

 has no more definite information to give us respecting it ; and it is 

 rather a pity that he has not given a detailed account of the cater- 

 pillar, accompanied with one or more figures, in the present work. 



The Buiterjli/ Bool-, a Popular Guide to a Knowledqe of the Butter- 

 flies of North America. By W. J. Holland, Ph.I)., D.D., LL.D., 

 Chancellor of the Western District of Pennsylvania ; Director of 

 the Carnegie Museum, Pittsburgh, Pa. ; Fellow of the Zoological 

 and Entomological Societies of London ; Member of the Entomo- 

 logical Society of France, &c. With 48 Plates in Color-photography, 

 reproductions of Butterflies in the Author's collection, and many 

 text-illustrations presenting most of the species found in the 

 United States. New York : Doubleday & McClure Co., 1898 ; 

 new edit. 1899. Roy. 8vo. Pp. xx, 382 ; col. pis. 48. 



This is the first approximately complete and practical manual of 

 the Butterflies of North America ; for the older publications on 

 the subject are necessarily both obsolete and very incomplete, and 

 most modern books deal only with the fauna of a limited district, 

 and are usually insuflficiontly illustrated, or else are so costly as 

 to be far beyond the reach of the ordinary student. So great was 

 the need of such a book as Dr. Holland's that many of the 

 entomologists of the United States and Canada eagerly bought it 

 on its first apjjearance, in many cases almost before it had got 

 into the market at all ; and the first edition was nearly exhausted 

 in less than a month after publication, as if it had been a new 

 novel by a popular author; but, we imagine, a quite unprecedented 

 event in the history of any entomological book. 



Hitherto Dr. Holland has chiefly been known to entomologists 

 by his papers on African Lepidoptera, but he has not neglected 

 those of his own country, and has had the good fortune to be able 

 to form one of the most complete collections and libraries in North 

 America relating to the subject. The present volume contains over 

 a thousand coloured figures, a large proportion taken from the actual 

 typical specimens, and no less than 150 species are here illustrated
