alder (Alnus japonica) and is found In abundance In swampy places along the 

 streams in Sapporo. 



New studies and observations of Argentine Pieridae, E. Giacomelli {Physis, 

 3 (1917), No. 15, pp. 370-385).— Thirty-nine species and 14 genera of this 

 economic group are noted. 



Ear worm injuries to corn and resulting losses, R. C. Smith (Jour. Econ. 

 Ent., 12 (1919), No. 3, pp. 229-233, pi. 1). — In reviewing the injuries caused by 

 the bollworm to corn it Is pointed out that two sources of serious loss have 

 been overlooked: (1) That due to its feeding on the germ or lower part of 

 the kernel after the endosperm has hardened and (2) the entrance of grain 

 weevils and other pests through the holes made by it in the husk. 



The status of the codling moth in its relation to the walnut industry, D. B. 

 Mackie (Mo. Bui. Cal. Coin. Hort., 2 (1919), No. 5, pp. 250-256, figs. 3).— TMs 

 is an account of further work with the codling moth as an enemy of walnut, 

 a brief account relating to which has previously been noted (E. S. R., 40, 

 p. 456). 



This pest is becoming a serious enemy of walnut in California, as high as 40 

 per cent of the entire crop being injured and sold as culls in certain orchards 

 in Orange County. It appears that with cooperation the pest can be controlled 

 in the field. The spread of this pest to orchards in sacks in which the worms 

 spin their cocoons can be readily prevented through the use of the electric 

 mangle at comparatively slight expense. 



Notes on lepidopterous borers found in plants, w^ith special reference to 

 the European corn borer, E. Mosher (Jour. Econ. Ent., 12 (1919), No. 3, pp. 

 258-268, figs. 4)- — This paper is prepared with a view to aiding field workers 

 and others in determining whether or not they have the European corn borer 

 at hand. 



Notes on the life history of the pine tube moth (Eulia pinatubana), A. 

 Haetzell (Jour. Econ. Ent., 12 (1919), No. 3, pp. 233-237).— This is a report of 

 studies made in the vicinity of Ithaca, N. Y., where the larva occurs in injuri- 

 ous numbers on white pine (Pinus strohus), which appears to be its only host 

 plant. The species was first recorded in the United States by Comstock in 1880 

 and was confused with the European species E. politana until 1905, when it was 

 described as new by Kearfott. 



Tubes are built by the larvae by drawing together leaves of the white pine 

 with silk, from 5 to 20 leaves being bound together in their construction. 

 Usually two or three of the leaves are left uneaten, which serve to hold the tube 

 In place even after many of the older leaves are dead. The larvae live singly, 

 and it Is thought probable that they may occupy more than one tube during the 

 larval life. The author's observations indicate that the species is single- 

 brooded in the latitude of central New York. The distribution of the species, 

 though not well known, appears to be throughout the white-pine district of 

 soutliern Canada and eastern United States. 



Records are given of rearings of 25 Individual parasites representing 8 species 

 of Hymenoptera, the Identifications of which were made by Girault, Cushman, 

 and Rohwer. 



What hinders dried fruit salesP E. R. de Ong (Mo. Bui. Cal. Com. Hart., 8 

 (1919), No. 5, pp. 240-243, figs. 4).— A brief discussion of the infestation of dried 

 fruit by the Indian meal moth. 



Observations on the food of Anopheles larvae, C. W. Metz (Pub. Health 

 Rpts. [U. S.], 34 (1919), No. 32, pp. 1783-1791).— The author reports studies 

 conducted in the summer of 1918 near Montgomery, Ala., and Lakeland, Fla., 

 which deal with Anopheles punctipennis, A. quadrimaculatus, and A. crucians,
