gathered from the best avaihible sources or specially prepared for the work, 

 constitute a most helpful addition for the amateur. We regret that the 

 author has not seen fit to include in this edition a bibliography of the more 

 important works. Despite some minor imperfections, this manual must re- 

 main for some years at least, the standard woi'k on Diptera, invaluable to 

 the amateur, indispensable to the specialist and most illuminating to the 

 general student of entomology. 



James Fletcher, LL.D. Ottawa Naturalist, January. 1909. p. 

 189-234. 



This memorial number will appeal most strongly to American entomolo- 

 gists. The major portion of the number is occupied by papers and testimo- 

 nials given at a memorial meeting held December 1, 1908. Dr. Saunders, 

 Mr. Harrington and Professor Macoun being some of the more widely known 

 participants. There are many delightful references to incidents in the life 

 of Dr. Fletcher, showing his great love for Nature, his unselfishness and, 

 most striking of all, his ability to leave a wholesome impression upon all 

 with whom he came in contact. Messrs. Gibson and Groh contribute a list 

 of the published writings of Dr. Fletcher. This memorial number is a strik- 

 ing tribute to the large place Dr. Fletcher filled in the hearts of his friends. 

 A life worthy of such a testimonial commands the admiration of all. The 

 editor is to be congratulated on the general excellence of this issue. 



Twelfth Report of the State Entomologist of Minnesota, by F. 

 L. Washburn, p. 1-205, 1908. 



This report contains valuable additions to our knowledge respecting a num- 

 t)er of important insects. There is an extended discussion, illustrated by an 

 excellent colored jtlate. of the apple leaf hopper, special attention being given 

 to repressive measures. Grasshopper control is briefly noticed. Original bio- 

 logical data on the green aphis, Toxoptera (/ni mi mini, the English grain louse, 

 MiK-rosrphum (/raiKiria and other species are i)laced on record and control 

 measures discussed. The report contains a record of the nursery inspection 

 work, including a sunuuary of the laws in force in other states. There is a 

 general discussion of spraying, with notes on a number of injurious, species, 

 and special notice of some important shade tree pests. There are extensive 

 records of experimental work with insecticides against the cabbage maggot. 

 An unusual feature is found in the series of abstracts of entomological papers 

 from the Experiment Station Record. Mr. R. A. A'ickery is the author of an 

 excellent paper on the anatomy of plant-lice. ^Ir. Brues describes a number 

 of new parasites of the cabbage maggot, while Doctor Franklin characterizes 

 the larvtTp and pupje of certain stalk borers. The report contains an excellent 

 series of original illustrations.
