1915 are briefly discussed and recorded. Some of the more important species, 

 including the army cutworm {Chorizagrotis auxiliaris), etc., are next considered 

 more at length. 



The amount of damage caused by insects during the year is said to have been 

 the greatest recorded by the state entomologist. Grain pests were especially 

 abundant, the army cutworm alone having destroyed at least 100,000 acres of 

 grain. The spotted fever tick (Dermacentor vcnustus) appeared in eastern 

 Montana in large numbers and a number of cases of spotted fever were reported 

 from that locality for the first time.

The paper by Brittain on apple insects deals at length with the more important 

 aphidids, etc., attacking the apple, namely, the green apple aphis, the rosy apple 

 aphis {Aphis sorbi), the woolly apple aphis {Eriosoma lanigera), the rose-leaf 

 hopper (Empoa rosw), the black apple leaf hopper {Idioceius fitchi), including 

 details of life history studies, and a number of other pests. 



Important insects which may affect the health of men or animals en- 

 gaged in military operations {U. S. Dcpt. Agr., Office Sec. Circ. 61 (1916), pp. 

 24, figs. 15). — This consists of brief descriptions of the insects which annoy or 

 affect the health of men or animals engaged in military operations, with informa- 

 tion regarding their control, particularly as applied to the Southwest.

" White ants " as pests in the United States and methods of preventing 

 their damage, T. E. Snydek (U. S. Dept. Agr., Farmers' Bui. 759 (1916), pp. 

 20, figs. 14).— A popular summary is given of the termites, the nature of their 

 injury, and preventive and remedial measures. 



Report on the inoculation of locusts with Coccobacillus acridionim, J. B. 

 RoBER (Bui. Dept. Agr. Trinidad and Tobago, I4 (1915), No. 6, pp. 197, 198).— 

 Inoculation experiments in Trindad with Venezuelan migratory locusts (Schisto- 

 cerca paranensis) and the giant Trinidad locust (Tropidacris dux) showed 

 C. acridiorum to be virulent for both species and that its virulence can be in- 

 creased by passage through a series of locusts.

 comparatively harmless for some years, is said to have been one of the most 

 serious pests during 1915-16. It has been reported, on the coast as well as 

 inland, as damaging fruit, field crops, and even flower gardens.
