 Dominion Entomologist. Cambridge: at the University

This book of 382 pages which has just been received,"is 

 undoubtedly the most comprehensive and complete volume 

 which has yet appeared on the extremely common insect, which 

 is abundant, unfortunately, everywhere, vir., the House-fly. 

 No insect of late years has received such world-wide attention 

 as has the species here discussed. This, of course, has been 

 owing to its relation to the spread of disease. The book 

 is not intended as a popular treatise on the stibject, but it has 

 been prepared largely for the use of entomologists, medical 

 men, health officers and others who would be interested scien- 

 tifically in the matter presented. The volume is divided into 

 six parts, viz.. Part I — The Structure and Habits of the House- 

 fly; Part II — The Breeding Habits; Life-history and Struc- 

 ture of the Larva; Part III — ^The Natural Enemies and Para- 

 sites of the House-fly; Part IV. — Other Species of Flies Fre- 

 quenting Houses; P'art V — The Relation of House-flies to 

 Disease; Part VI — ^Control Measures. Three full page coloured 

 plates and 104 text figures illustrate the volume. Students of 

 the subject, ever^^where, will welcome the appearance of this 

 important book. It will undoubtedly be a valuable work of 

 reference for many years to come. 



Bird Houses and How to Build Them. In view 

 of the interest which is now being taken in the protection 

 of our native insectivorous birds in various parts of 

 Canada, the United States Departinent of Agriculture, Farmers' 

 Bulletin No. 609, bearing the title, "Bird Houses and How to 

 Build Them", will prove of much interest. This bulletin of 

 19 pages, prepared by Mr. Ned. Dearborn, Assistant Biologist, 

 discusses briefly many forms of bird houses, nesting boxes, etc. 

 Food shelters are also described. Forty-eight illustrations 

 are given.
