American Arbor- vitse, or Wliite Ceda»r, of Eastern Ontario and Western Que- 

 bec, for the past three years. With Mr. Busck's excellent paper there should 

 be no trouble in recognizing any species that have been described. 



Caudell, Andrew Nelson, The Decticinse (a group of Orthoptera) of 

 North America, ninety-four figures. (Separate from Proc. U. S. National 

 Museum, Yol. XXXII, pp. 285-410, published May 23, 1907.) An important 

 paper and one which will be of great help to those studying Orthoptera. Mr. 

 Caudell deals in an exhaustive way with a group which has been found very 

 troublesome to students. His opportunities to study a large number of 

 specimens and also of having travelled extensively in the localities whcTe 

 many species occur have given him facilities which few have enjoyed. The 

 figures given are excellent and will be of great assistance to those working at 

 these difficult insects. Several published species have been reduced to 

 synonyms and new genera have been erected, but the work is very thorough 

 and all orthopterists will be grateful to the author for this timely monograph. 



Chittenden, F. H., Sc.D., U. S. Department of AgTiculture, Insects 

 Injurious to Vegetables. Small 8vo. New York. Orange Judd Co., 262 

 pp., 163 illustrations. This is a handy little manual treating briefly of the 

 best known insects which attack vegetable crops and giving the remedies 

 usually applied. Preliminary chapters deal with the value of a knowledge 

 of entomology, the classification of insects, practical agTiculture and artificial 

 remedies, and apparatus. Not only will this book be of use to gardeners, but 

 it should be a convenient handbook for students and teachers. 



Dyar, H. G., Eeport on the Mosquitoes of the Coast Region of California, 

 with Descriptions of New Species. (Proc. U. S. Nat. Museum, Yol. XXXII, 

 pp. 121-129). Although a paper of only a few pages, this article by Dr. 

 Dyar will be read with much interest by our western dipterists, as it deals 

 with many species which are found in British Columbia and some other parts 

 of Canada. Anoi^heJes inaculipennis of the West is now Anopheles occiden- 

 talis D. & K. A majority of the species treated eitheT have been already 

 found in British Columbia or are sure to be discovered as more extensive 

 collections are made. The value of securing the preparatory stages is shown 

 in many instances in the present paper. Anyone having opportunities of 

 rearing the larvse of mosquitoes should be careful to save the exuviae and 

 foTward them to Dr. Dyar with the specimens for examination, remembering 

 always that a few perfect specimens are of far more value than a large num- 

 ber of broken ones. 



Casey, T. L., A Revision of the American Components of the Tenebrio- 

 nid sub-family Tentyriinse (Washington Academy of Sciences, Yol. IX, pp. 

 275-522). October 18, 1907. In this important work Major Casey mono- 

 graphs in a thorough manner and brings up to date all that is known of "that 

 part of the great family Tenebrionidse, having the abdominal segments un- 

 modified by a coriaceous hind margin and the middle coxse enclosed externally 

 by the sterna alone, without the intervention of a small piece attached to the 

 coxse and sometimes separating the sterna, known as the trochantin." This 

 was Leconte and Horn's definition of the subfamily and has been adopted 

 tentatively for the meantime. The author suggests that he may have over- 

 stepped the limit of prevailing conservatism in proposing new genera, but 

 the high quality of Major Casey's work during many years has prov d 

 that although it has occasionally been somewhat severely criticised, on 

 account of this very feature, and the great convenience and stability of a large 

 proportion of his differentiations, these are being adopted more and more 

 even by the most conservative As in the case of his work on Staphylinidse, 

 noticed last yea-r, much foreign material has been used in making comparison
