the Army Worm. Several ingenious plans are given for destroying 

 the potato beetle or preventing its ravages, and two new machines, 

 for the same purpose, are described; the results of numerous experi- 

 ments with Paris-green, to ascertain if poisonous to the tubers, are 

 also gixen. Paleacrita vernata and Anisopteryx pometaria are com- 

 pared from egg to imago, to show why they should be placed in separ- 

 ate genera, the first named genus having been erected by Mr. R., for 

 the old and commonly accepted species of canker worm. Leucania 

 unipitricta, the army worm, is next treated in a paper well illustrated, 

 and replete with interesting statements as to natural history, habits, 

 parasites, etc. The greater portion of the remaining pages are devo- 

 ted' to the Rocky Mountain locust, in which is given a history of the 

 terrible visitation of 1875, together with much valuable information, 

 statistics, &c, from actual investigation, and various othdr sources. 



While upon the subject of legislation, both national and local, the 

 author indulges in a little plain talk, which is much to the point, 

 though he should relinquish the idea that the Commissioner of Agri- 

 culture has any duty in the matter under consideration, as he has 

 had neither the power, or the funds, to authorize such an extended 

 investigation as this vexed grasshopper question demands; however, 

 before seeing Mr. Riley's report, we had given our views on the sub- 

 ject, and they will be found upon another page. 



Annual Report of the Entomological Society of Ontario, for 



THE YEAR 1875. By Wm - SAUNDERS, REV. C. J. S. BETHUNE, AND 



R. V. Rodgers. [Large octavo, pp. 54. Illust. xxx.] Toronto, 



printed by Hunter, Rose & Co. 



The Annual Report of this flourishing Association of Entomologists 

 "across the line" is again before us, and contains the usual amount of in- 

 teresting matter. In addition to papers by the gentlemen named above, 

 upon the subjects of noxious insects, it contains reports of meetings 

 of the several branches of the Society, annual addresses, of the 

 retiring and incoming presidents, with other matter, and the paper by 

 Dr. LeConte on methods of Subduing Injurious Insects to Agriculture, 

 read before the American Association for the Advancement of Science, 

 at the Detroit meeting. 



In the report upon insects, the first paper, by Mr. Saunders, is upon 

 the subject of Canker-worms. The habits of both species are fully 

 described, with wood illustrations and a page is devoted to remedies. 

 Mr. S. also presents notes of the year, and a paper on some of our 

 common Insects. Mr. Rodgers in a paper bearing the last named title 

 gives the history of the Luna moth (Actias lima) and Mr. Bethune 

 treats in an interesting manner the subject of the Western Locust, 

 ( Caloptenus spretus) devoting several pages to the means of reducing 

 their ravages.
