263 THE CANADIAN ENTOMOLOGIST. 



Extomologen-Adressbuch. — By W. Junk, Rathenower Strasse 22, 

 Berlin, N. W., Germany. (Price 5 marks.) 

 This directory of Entomologists throughout the world contains about 

 9,000 names and addressess, with in most cases the special orders or fam- 

 ilies of insects to which the individual is devoted. The list is arranged 

 under countries, but there is added an alphabetical index which increases 

 its convenience very much. The volume includes also a catalogue of 

 over one hundred pages of new and second-hand books for sale by the 

 publisher. 



Genera Insectorum. — Published by P. Wytsman, Brussels, Belgium. 



Fascicule 24 — Heteroptera: family Pentatomidpe,sub-fam. Scutellerinse, 

 by H. Schouteden. This part consists of 98 pages, with five coloured plates 

 on which are depicted about 80 species of Bugs, and several drawings in 

 the text. It is written in French. 



Fascicule 25 — Isoptera : family Terraitidfe, by Jules Desneux (also in 

 French), contains 52 pages and two coloured plates showing 12 species 

 of " White-ants," with many details of structure. 



Fascicule 26 — Diptera : family Culicidse, by Fred V. Theobald (in 

 English), contains 50 pages and two coloured plates showing 24 species of 

 Mosquitoes. 



These parts are all on the same general plan, giving a full description of 

 the family treated of, keys to sub-families and genera, the characters 

 of each genus and a list of species with geographical distribution and 

 bibliogiaphy. They are of very great value to those studying the partic- 

 ular group of insects treated of, but there is a difficulty in procuring 

 them, as subscriptions are apparently taken only for the whole work, and 

 the parts are not sold separately. As the entire cost will probably ap- 

 proach $400, very few students of Entomology can afford such an outlay, 

 while many would be delighted to purchase for a few dollars the part in 

 which they are specially interested. 



Reports ok the Experimental Farms of the Dominion for 

 1904. — This goodly volume of over 500 pages contains a vast fund of 

 information on every variety of subject that can interest the farmer, fruit- 

 grower or gardener. In the portion furnished by Dr. Fletcher (pages 

 205-256), there are descriptions of a large number of insects affecting 

 cereals and field crops, roots and vegetables, fruit crops, and forest and 

 shade trees ; special attention is drawn to the Pea-weevil and 

 Cut-worms among many other insect foes which have to be contended 

 with. He also furnishes in the Botanical portion, an account of the 

 injury to grain crops by Rust last year, which was most exceptional in 

 extent, owing, evidently, to peculiar atmospheric conditions. 



Mailed June 29lh, 1905.
