covered with one thickness of copper mosquito netting, 15 wires to the inch, the 

 open edges of which are drawn up and tied to the rim. By using a 3-ft. hickory 

 sapling bent as a bow and the ends fastened to the opposite sides of the rim 

 a good coating can be applied to rows varying in width from 18 in. to 3 ft. by 

 twirling the apparatus over the row as the operator walks along. 



From 80 to 00 lbs. of the mixture are required per acre for each treatment. 

 Ordinarily two applications are sufficient, the first when weevil-feeding on the 

 bud begins and the second about one week later or as soon as the coating given 

 by the first treatment has lost its completeness. Every bud should be kept 

 dusty.

 Infernnt. Rcr. Fici. and Pract. Agr., 7 (1916), No. 6. pp. 910-912).— Control ex- 

 periments with the cockchafer (MeloJontha vulgar-is and M. hippocastani) in the

 fourth) paper (E. S. R., 36, p. 555) with descriptions of three parasites new to 

 science, includes Podagrion mantidiphagtim reared from an egg mass of a 

 mantid in the Briti.sh West Indies, and Parol eptomnstrix notatus reared from 

 Pseudococ(yns bakeri on the grape at Fresno, Cal. 



Notes on chalcid flies, chiefly from California, A. A. Giraxjlt (Jour. Ent.

 given.

 search, 7 (1917), No. S, pp. 231-257, figs. 9).— This second paper (E. S. R., 87, 

 p. 162) presents descriptions of seven chalcidoid parasites of Coccida? from the 

 Gold Coast that are new to science. 



Annual reports of the State bee inspector for the years 1915 and 1916, 

 F. C. Pet.lett (Ann. Rpt. State Bee Insp. lotva, 4 (1915), pp. 72, pis. 2, figs. 9;

The question of denatured sugar for the feeding of honeybees, E. fX. Zarin 

 (Trudy Selsk. Khoz. Bakt. Lab., 5 (1915), pt. S, pp. 37 IS 90). —This discussion 

 includes a report upon the experimental feeding of bees with sugar denatured 

 with various substances. In experiments with paprika and methyl violet, coal 

 tar and animal oils, the latter was found the better, as a moderate addition 

 of the animal oil can not influence harmfully the color or taste of the honey. 



Beauveria peteloti n. sp., a polymorphous Isaria parasite of Hymenoptera 

 in tropical America, F. Yincens (BuI. Soc. Bot. France, 62 (1915), No. 4-6, pp. 

 132-144, pis. 4)- — This fungus is parasitic on two wasps (Polybia chrysothorax
