removed after refrigeration for 24 and 27 days, respectively, yielded adults; 

 500 pupfe removed after refrigeration for from 31 to 34 days proved to be dead. 



" It does not seem safe to conclude that the age of the pupa has a direct 

 bearing upon its ability to withstand the more ordinary ranges of cold-storage 

 temperatures." 



The bean maggot in 1915, D. B. Whelan (Michigan Sta. Circ. 28 (1916), 

 pp. 3, 4)- — Serious damage was done by the bean or seed-corn maggot in Huron, 

 Sanilac, Tuscola, Saginaw, Gratiot, Eaton, and Berrien counties in Michigan 

 during 1915, previous to which year it had appeared in scattered numbers over 

 quite a large area and the damage had been comparatively slight. Instances 

 are reported of fields in which the loss of plants varied from 50 to 80 per ^ent. 

 Examinations of a series of bean fields beginning on July 1 showed that the 

 maggots had been present in the fresh manure, clover sod, and the rotting 

 stems of clover, and had transferred their attention to the beans. The eggs 

 are usually deposited on the stems of the plants just coming through the soil 

 or on decaying vegetable matter. 



It appears that cultural methods furnish the best means for combating this 

 maggot. Land which is in clover or is covered with manure should be plowed 

 early and prepared, so that the soil will be in good condition and the maggots 

 given time to disappear before the beans are sowed. " Commercial fertilizers 

 may be substituted for barnyard manure when the necessity for late fitting 

 of the soil demands it, and repeated harrowing and perhaps rolling, especially 

 when the ground is light in texture, seem to aid." 



The adaptative forms of anthomyid larvae; Anthomyidae, the larvas of 

 which are carnivorous, D. Keilin (Bui. Soc. Ent. France No. 20 (1914), pp. 

 496-501, figs. 3; abs. in Ent. Mo. Mag., S. ser., 1 (1915), No. 8, pp. 242, 243).— 

 In continuation of investigations of dipterous larvse the author, in dealing with 

 the Anthomyidse, refers to larvse with saprophagous, phytophagous, parasitic, 

 and carnivorous habits.

White grubs in Iowa, R. L. Webster (loiva Sta. Circ. 29 (1916), pp. 4,

 and discusses control measures. 



An insect pest of lucern, C. French, Jr. (Jour. Dept. Agr. Victoria, 13 (1915), 

 No. 9, pp. 567-569. figs. 3). — The cockchafer Heteronyx piceus has been found

Bud weevils and other bud-feeding insects of Washington, M. A. Yothees 

 (Washington Sta. Bui. 124 (1916), pp. 5-43, pis. 6, figs. S).— This paper reports 

 observations made of the biology and control of weevils and other beetles which 

 have been injuring the fruit buds of one- and two-year-old fruit trees in Wash- 

 ington State. It appears that several of the weevils are native feeders on the
