The Parasitic Diseases of Poultry; by Fred V. Theobald, A. M., 

 F. E. S; 12 mo., pp. 120. Gurney & Jackson : i Paternoster Row, 

 London, 1896. 



It is encouraging to see a growing interest in applied entomology in 

 England, and Mr. Theobald has given, in this handy little volume, a popu- 

 lar account of not only insect parasites but all other parasitic troubles 

 likely to confront the poultry breeder. Not only is the little manual 

 ■especially fitted for the wants of such, but it will doubtless find its way to 

 the library of many other gentlemen who rely upon their estates to furnish 

 fowls for their tables. The book is divided into several parts, relating to 

 protozoan parasites, insect parasites, mite parasites, worm parasites, and 

 vegetable parasites. Besides containing twenty -three illustrations, 

 appendix I. gives a list of the parasites of Gallus dotnesticus, with the part 

 of the fowl attacked by them; appendix II. a quite full bibliography of 

 the literature of the subject, which, with a very complete index, renders 

 the volume of scientific as well as practical value, and Americans will find 

 it of interest to them as well as Englishmen. We wish Mr. Theobald suc- 

 cess in his efforts to add to the practical entomological literature of his 

 people. F. M. W. 



Uber die Palpen der Rhopaloceren. Ein Beitrag zur Erkenntnis der 

 Verwandtschaftlichen Beziehungen unter den Tagfaltern ; mit 6 

 Tafeln : von Dr. Enzio Renter. Acta Societatis Scientiarum Fennaciae. 

 Tom. XXII., No. I. Helsingfors, 1896. 



Entomologists in general, and lepidopterists in particular, will be 

 interested in this work of Dr, Renter's, occupying as it does a folio 

 volume of 577 pages, the investigations, upon which the facts are chiefly 

 based, requiring the examination of 3,557 palpi, belonging to 670 species, 

 contained in 302 genera of the Rhopalocera. The work is divided into 

 two parts : the first dealing with the direct microscopical examinations in 

 descriptive form, while in the second is given the conclusions based on 

 the same, as well as a discussion of other taxonomic characters allied to 

 those brought out by himself, and their values. The plates are very fine, 

 and the sixth of especial interest generally, as it presents, in the form of an 

 evolutional tree, the relations of the various groups and genera to each 

 other.
