Diseases affecting the grape, J. II. Paxiox {Ontario Jgl. College and Exptl. 

 Farm Bui. 0~, pp. 11, figs. S). — Popnlar illustrated notes on the downy mildew, or 

 brown rot {Vvronospora viticola), black rot of the grape {La'stadia bidwellii), powdery 

 mildew ( Uiuiiiiila spiralis), and anthracuose {Sphaceloma ampelinum), with directions 

 for combating them with fungicides, formulas for which are given. 



Five hundred and fifty-one reydies were received to a circular letter regarding 

 the diseases of the grape, and 120 report downy mildew, 105 powdery mildew, lOli 

 black rot, and 14 anthracuose. These diseases caused a loss of from 50 to 75 per 

 cent of the crop. The varieties most attacked are Rogers hybrids, Concord, Clinton, 

 Niagara, Brighton, and Delaware.

• ENTOMOLOGY. 



On certain grass-eating insects, a synopsis of the species of 

 Ciambus of the Ithaca fauna, E. P. Felt {Keic York Cornell t^ta. 

 Bui. 64, pp. 47-102, pis. 14, figs. 8). 

 Synopsis. — Introduction, synojisis of species, description of species, the affinities 



of species, bibliography and recorded distribution of the North American 



species of the genus Crambus, and explanation of plates. 



This paper is maiuly a technical monograph, but in the intioductiou 

 the destructive habits of the crambid larvae in feeding upon the leaves 

 of grasses, cereals, and sedges are treated of, though the injury they 

 intlict is usually inconsiderable. Burning of the infected tract in late 

 fall or early spring, while the larvae are hibernating in their nests 

 at the bases of the grass stems, is recommended, as also rolling the 

 ground and deep plowing. 



Three tables are given, the first an artificial key for the identifica- 

 tion of 20 species, the second showing the periods of flight for 14 species, 

 and the third synoptical, based on a study of the exterior genital organs 

 of 20 species. 



Sixteen species of snout moths are described and their habits noted, 

 as follows: the yellow crambus {Crambus luteolellus), sooty crambus {C.
