102 THE EEPOET OF THE No. 36 



Canadian collectors and students, as in previous years, have received invalu- 

 able help from the leading specialists in the United States and elsewhere. Particu- 

 lar acknowledgment is due to Dr. L. 0. Howard, and his expert associates, Dr. 

 H. G. Dyar and Mr. W. D. Coquillett, of Washington, D.C.; Dr. J. B. Smith, of 

 New Brunswick, N.J.,; Sir George Hampson, of the British Museum; Mr. W. D. 

 Kearfott, of Montclair, N.J.; Prof. H. F. Wickham, of Iowa City, Iowa; Mr. E. P. 

 Van Duzee, of Buffalo, N.Y.; Mr. W. Beutenmuller, of New York, N.Y.; Dr. 

 Henry Skinner, of Philadelphia, Pa.; Dr. E. M. Walker, of Toronto, Ont.; Col. 

 Thos. L. Casey, of Washington, D.C.; Mr. Chas. Leibeck, of Philadelphia, Pa.; 

 Eev. G. W. Taylor, of Departure Bay, B.C., Mr. C. H. Eoberts, of New York, Mr. 

 J. D. Evans, of Trenton, Ont., Mr. W. H. Harrington, of Ottawa, and Mr. P. H. 

 Wolley-Dod, of Millarville, Alta. Mr. Dod is specializing in North American 

 noctuidte and will be pleased to name and return any specimens submitted to him. 



Literature. 



Among the many valuable publications which have been received during the 

 past year, and which are of interest to Canadian students, mention may be made of 

 the following:— 



Banks, Nathan. Catalogue of Nearctic Spiders. Smithsonian Institution, 

 United States National Museum, Bulletin No. 72. This publication takes the 

 place of the Marx Catalogue prepared some twenty years ago. The author states 

 that the catalogue includes a little over 1,300 species. " The largest family is the 

 Theridiidffi, with 298 species; the Attidas is next with 213; two other families, the 

 Lycosidffi and Epeiridse, have over 100 species in each. Sixteen families have 

 less than 10 species apiece." This work will be a most useful one. Many of the 

 species occur in Canada,, but comparatively few definite records are available. The 

 publication of this catalogue will undoubtedly lead to more systematic work, and it 

 is to be hoped that entomologists in Canada will do their share in working up local 

 species. 



Beutenmuller, William. The North American species of Neuroterus and 

 their Galls, (issued May 20, 1910) ; The North American species of Aylax and 

 their Galls, (issued May 20, 1910) ; The North American species of Aulacidea and 

 their Galls, (issued July 16, 1910) : American Museum of Natural History, New 

 York. These papers are a continuation of the results of Mr. Beutenmuller's studies 

 on American Cynipidffi and their Galls. They are very useful publications. The 

 illustrations are particularly good ; in fact they could not be otherwise, coming 

 from the hand of Mrs. Beutenmuller. Several Canadian records appear in the 

 above contributions. 



Blatchley, W. S. The Coleoptera or Beetles of Indiana; Department of 

 Geology and Natural Eesources; Bulletin No. 1, State Printers, Indianapolis; 

 1386 pages, with nearly 600 excellent illustrations. No book has appeared during 

 the year which will give such general pleasure to entomologists as Professor 

 Blatchley's magnificent work on the beetles of Indiana. Such a work has been 

 much wanted, and although the author has confined it to the above State, it will, 

 nevertheless, be of the greatest use to students in Ontario and other parts of 

 Canada. Many of the species which occur in Indiana are to be found in Canada, 

 and from the descriptions of families and genera and the keys to the genera and 

 species and the descriptions thereof, students are now able to run down many insects 

 which otherwise could only be determined by the specialist. Unfortunately the 

 edition of this work is small, and many, doubtless, will be unable to obtain a copy.
