Th.e principal insect pests and plant diseases, V. A. Huard (ilin. Agr. 

 Prov. Quebec Bui. 23 (1916), pp. 75, figs. 78).— This paper, which is in the 

 French language, consists in large part of accounts of the more important insect 

 pests of the Province. 



Garden and truck crop insect pests, C. E. Sanbobn (Okla. Agr. Col., Ext. 

 Div. Circ. 41 {1916), pp. 76, figs. 78). — This is a popular account of the more 

 important insect enemies of truck and garden crops in Oklahoma. 



Potato insects, M. A. Yothers (Washington Sta. Popular Bui. 106 {1011), 

 pp. 96-123, figs. 17). — This is a brief descriptive account of the more important 

 insect enemies of the potato in Washington, with directions for their control. 

 Those mentioned as affecting the foliage are the apple leaf-hopper, blister 

 beetles {Epicauta maculata and E. oregona), the Colorado potato beetle, cut- 

 worms, grasshoppers, the potato aphis {Macrosiphum solanifolii), and the 

 tobacco worm. The insects, etc., which affect the tubers include the sand 

 cricket {Stenopelmatus sp.), wireworms, and eelworms {Ileterodera spp.). 

 Those which affect both foliage and tubers are the potato tlea beetle {Epitrix 

 subscrinita) , the potato tuber worm, and the twelve-spotted cucumber beetles 

 {Diabrotica soror, D. 12-punctata, and D. 12-punetata tenella). 



South American crickets, Gryllotalpoidea, and Achetoidea, L. Bbuneb (Ann. 

 Carnegie Mus., 10 (1916), Xo. 3-4, pp. 344-428). — This paper contains descrip- 

 tions of a number of apparently new forms. 



Notes on the black apple leaf hopper (Idiocerus fitchi), W. H. Bkittain 

 and L. G. Saunders (Canad. Ent., 49 (1917), No. 5, pp. 149-153, pi. i).— This 

 leaf hopper, originally described from New York State, apparently occurs quite 

 generally throughout the northeastern United States and Canada and is said 

 to be very common throughout the Annapolis Valley of Nova Scotia. While 

 considered by many farmers a pest of some importance, observations indicate 

 that the injuries attributed to it have largely been brought about by other 

 causes. 



Technical descriptions of its several stages and brief notes on its life history 

 are given. 



Additions to the list of Missouri Cicadellidee, E. H. Gibson (Canad. Ent., 

 49 (1917), No. 2, pp. 75, 76). — Supplementary to the paper previously noted 

 (E. S. R., 35, p. 463). 



Three new species of Jassoidea from Missouri, E. H. Gibson (Canad. Ent., 

 49 (1917), No. 5, pp. 183, 184)- — The three new species here described supple- 

 ment the lists of Jassoidea occurring in Missouri noted above. 



The bay flea louse, Trioza alacris, as a new pest in New Jersey, H. B. 

 Weiss (Canad. Ent., 49 (1917), No. 2, pp. 73-75).— This psyllid has been present 

 in several greenhouses in New Jersey for the past several years, but not until 

 recently has it increased sufficiently to disfigure seriously its host plant, Lauras 

 nob ills. 



Fvirther data on the relation between aphids and fire blight (Bacillus 

 amylovorus), J. H. Mebbux (Jour. Econ. Ent., 10 (1917), No. 1, pp. 45-47, 

 pi. 1). — In further observations (E. S. R., 34, p. 452), the author finds blight 

 to develop only in the tender succulent growth on the twigs. By hatching from 

 eggs laid in blight cankers the aphids come in contact with the fire blight or- 

 ganisms, and can and do inoculate trees with the bacteria of fire blight. It 

 appears that the amount of fire blight infection in an orchard may be materially 

 decreased by destroying all of the aphids which may appear there. 



Synopsis of the genus Saltusaphis, A. C. Bakee (Canad. Ent, 49 (1917), 

 No. 1, pp. 1-9, pis. 2, figs. 17). — Five members of this genus which live on sedges 

 and in marshy localities are recognized as occurring in America, three of which 

 are here described as new.
