preserving and rearing mites are given on pages 141 and 112, and on pages i43- 

 145 a list of works, useful in the study of American Acarina, is given. 



Braun, Axnette Frances. Evolution of the color pattern in the Micro- 

 lepidoptcrous Genus Lithocolletis : Journal of the Academy of Natural Sciences of 

 Philadelphia, Vol. XVI, Second Series, Philadelphia, pp. 105-168, plates III and 

 IV, 26 text figures. A separate of this article (issued February 12th, 1914) has 

 recently been received. Under " Methods and Observations " the author dis- 

 cusses (a) Systematic Position and Characteristics of Lithocolletis, (b) Color 

 Classes Eepresented and Structure of Scales, (c) Comparative Study of the Adult 

 Markings, (d) Ontogenetic Development of the Color Pattern and (e) Phylogenetic 

 Development of the Color Pattern. The two plates, in colors, at the end of the 

 article well illustrate the various species of the genus. The paper is a most in- 

 teresting one and undoubtedly of much value. 



Brues, Charles T., and Melander, A. L. Key to the Families of North 

 American Insects: published by the authors; Boston, Mass., and Pullman, "Wash., 

 1915, pp. 1-140. As stated by the authors this manual brings together a brief, 

 yet complete, key to the families of American insects, unhampered by more than 

 the explanations needed to make such a tabulation available to the general student. 

 It has been prepared to meet the requirements not alone of college courses in 

 systematic entomology, but also of agricultural high schools and of physicians, 

 fruit inspectors, the modern farmer, the nature lover, or anyone who is con- 

 cerned with the practical identification of insects. This very useful work Avill 

 undoubtedly be widely received. 18 full-page plates, illustrating structural char- 

 acters, etc., are included. 



Casey, Thos. L. Memoirs on the Coleoptera, VI; published by the New Era 

 Printing Company, Lancaster, Pa.; issued November 27th, 1915, pp. 1-460. Tlie 

 contents of this the sixth memoir by this well-known coleopterist consists of: Part 

 I, A Review of the American Species of Rutelinge, Dynastins and Cetoniinje, pp. 

 1-394; Part II, Studies in some Staphylinid Genera of North America, pp. 395- 

 450. A large number of new species are described, seventeen of which are from 

 Canada. 



Fracker, Stanley Black. The Classification of Lepidopterous Larvse, 

 with ten plates: Illinois Biological Monographs, No. 1, Vol. II, July, 1915; pub- 

 lished by the University of Illinois, under the auspices of the Graduate School, 

 Urbana, 111., pp. 1-169, (contribution No. 43, from the Entomological Laboratory- 

 of the University of Illinois). This contribution is divided into two section?, 

 namely. Part one— The Homology of the Seta3, and Part two— Systematic Outline 

 of Families and Genera. The work is a most interesting one. The author in 

 Part One suggests the adoption of Greek letters in place of the Eoman numerals 

 now generally used to designate the different tubercles. In the second part, family 

 and generic keys are given, based on larval characters. The plates at the end 

 illustrate arrangement of setas, etc. This contribution is indeed a valuable one 

 and will doubtless receive much consideration from lepidopterists generally. 



Hampson, Sir George F. (Bart). Catalogue of the Lepidoptera Phalaens 

 in the British Museum; Supplement, Vol. I, Catalogue of the Amatidae and 

 Arctiada}, (Nolinse and Lithosiana}). Eeceived 19th January, 1915. Since the 

 publication of the first two volumes of the " Catalogue of Moths " a large number 

 of species in the families of which they treat have been described, and the newly 

 published supplement brings the subject matter of Vols. I and II up to date. In 

 the Family Amatidaj, 29 species are described as new, none of which, however, are
