Casey, Thos, L. Memoirs on the Coleoptera, 1 : Xew Era Printing Co., 

 Lancaster, Pa. ; issued September 24, 1910. This memoir, of 205 pages, by Col. 

 Casey, the well-known student of coleoptera, is indeed an important publication. 

 It is divided into 2 parts: 1 — New species of the Staphylinid Tribe Myrmedoniini; 

 2 — Synonymic and descriptive notes on the Paederini and Pinophilini. Altogether 

 3*65 species are described as new, 25 of which are from Canada. Of these 25, all 

 but two occur in British Columbia, and were mostly collected by the Eev. J. H. 

 Keen, the enthusiastic naturalist, at Metlakatla. The two other species are from 

 Ontario, one collected at Toronto and one at Ottawa. This further work on 

 Staphylinid beetles will be of great interest to coleopterists. Such memoirs repre- 

 sent much close study, and the author deserves great credit for this additional con- 

 tribution to the knoAvledge of these insects which are so difficult to study. 



CoQUiLLETT, D. W. The Type-species of the North American Genera of 

 Diptera. Proc. U. S. Nat. Museum, Vol. 37, pages 499-647; published August 4, 

 1910. " The great importance of knowing definitely what species is the type of 

 any given genus is now recognized by practically every worker in the field of 

 biology." This important contribution is the result of several years of work in 

 ascertain ing the types of the genera of diptera reported as occurring in North and 

 Middle America. It contains all the genera known to the writer up to January 

 1, 1909, together with their type-species and synonymy. Students of diptera will 

 find this publication of extreme value. In the Canadian Entomologist for Novem- 

 ber, 1910, Mr. Coquillett points out several corrections and omissions to the above 

 paper, which should be noted by those who possess a copy of the article. 



DiETZ, "W. G. Eevision of the Blastobasidse of North America. Trans. Amer. 

 Ent. Soc, Vol. xxxvi, Jan.-March, 1910, pp. 1-72, plates I.-IV. This interesting 

 paper deals with 66 different species, several of which are recorded from Canada. 

 Thirty-six are described as new. The author states in the beginning of the paper 

 that " the Blastobasidag, as now understood and distinguished from the Q^cophoridse, 

 form a well defined family of the Tineina. This revision will be of much use to 

 students of the microlepidoptera. Doubtless many others of the species listed will be 

 found in Canada. 



Geossbeck, John A. Studies of the North American Georaetrid Moths of the 

 Genus Pero. U. S. Nat. Museum, Vol. 38, pages 359-377. with Plates 13-16; pub- 

 lished August 19. 1910. In this interesting paper Mr. Grossbeck gives the results 

 of his investigation in the above named genus (= Azelina Guenee in part). Long 

 series were gathered together from different parts of the United States and Canada, 

 and four new species recognized. Four plates are added, one of these figures the 

 adult moths, another structural characters and the remaining two show the geni- 

 talea of the species. 



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

 in the British Museum, Vol. IX, Noctuida\, 1910. 552 pp.. plates cxxxvii to cxlvii. 

 Received ]\Iay 2. This volume " is the third and final part of the very large 

 Noctuid subfamily A crony din ce; it contains 725 species belonging to 185 genera, 

 as compared with 843 species belonging to 96 genera in Vol. VII, and 720 species 

 belonging to 104 genera in Vol. VIII." Many of the species figured in the beauti- 

 ful plates occur in Canada, and owing to the great care of the artist, in most 

 instances, it is an easy matter to determine our North American forms. These 

 volumes are eagerl;^ looked forward to by lepidopterists. A^ol. IX. is extremely inter- 

 esting as it deals with many species which have of recent years been studied by 

 American entomologists. Collectors in Canada should assist Sir George Hampson 

 in his great work by sending him material from tlieir respective districts. In this
