Ecoxo~ne ExTo,lOLor;y,- Sanderson's In· sects injurious to staple crops (~ew York , John \\'iley and Sons, 190~) contains fifteen chapters denJted to Injury done Maple crops by insect pests. Structure and development of in sects, General farm practice against in· jurious insects, Beneficial inset:ts. In sects injuriou~ to gra in s and grasses, to wheat, to Indian corn, \\'ee,·il in grain, Insects injurious to c lo,·er, to cotton, to tobacco, to th e potato, to the sugar-beet, to the hop-plant, and Insecticides.

The text though compiled and not comprehensive will serve the purpose of the author fairly well ; a direct reference to a detailed account of each species would have been of real benefit. ;\lost of the illu strations ha,·e been used preYiously and the source is acknowledged though in some cases inadequately; the helpfulness of some of the original cuts (r. g. Figs. 4 and 5} may well be question ed.
