Contributions to our knowledge of the weevijs of the superfamily Cur- 

 culionoidea, W. D. Pierce {froc. Ent. Soc. Wash., 21 (1919), No. 2, pp. 21-36). 



[Apicultural work] (loica Sta. Rpt. 1918, pp. 31, 3.2).— In tests of the com- 

 parative yield of honey from 1-, 2-, and 3-Ib. paclvages of bees shipped from 

 tlie South, the 1-lb packages gained 12 lbs. during the season, the 2-lb. packages, 

 39 lbs., and the 3-lb packages, 45 lbs., while the average gain from over- 

 wintered swarms was 59 lbs. In a study of the cost of wintering bees, it was 

 found that each colony consumed about 17 lbs. of stores from October to April, 

 inclusive. Careful measurements of a large number of bees from the best and 

 from the poorest colonies showed the average length of the tongues of the 

 highest producing colony to be 4 per cent greater than that of the lowest 

 protluchig one, and this variation was found to be quite consistent. 



The clover seed chalcid (Brucliophag'us funebris), W. Williamson {Rpt. 

 State Ent. Minn., 11 {19m, PP- 95-110, figs. 10).— X report of this pest, based 

 upon investigations in Minnesota, where it appears to be present wherever 

 clover is grown. Tlie greatest amount of damage to clover seed recorded in 

 iMinncsota is 39 per cent. 



New genera and species of ichneumon flies, R. A. Cushman {Proc. Ent. 

 Soc. Wash., 21 {191'.)), No. 5, pp. 112-120. fig. 1) . — This paper contains descrip- 

 tions of three new genera, namely, Derocentrus, Cyrtobasis, and Atopognathus, 

 tbree new species, and a new variety of the Icbneumonidre and one new 

 braconid species. Among the new forms are Hyposnter fugitiv'us pacificiis 

 from Alalacosonui pluiyiaHs and M. amhisimilUs from Tacoma, Wash., and 

 several localities in Califoi-nia, and Apanteles iselgi from Canarsia hammondi 

 at Bentonville, Ark. 



A new genus of chalcid wasp belonging to the family Eulophidss, A. B. 

 Gahan {Proc. Ent. Soc. Wash., 21 {1919), No. 1, pp. 2-8, fig. 1).—The genus 

 Apterolophus is erected for A. jmlchrOcornis n. sp., thought to be parasitic on 

 tlie larva of Epurgijcus tityrus. 



Parasite introduction as a means of saving sugar, T. E. Holloway {-Jour. 

 Econ. Ent., 12 {1919), No. 2, pp. 175-178) .—A brief account of the introduction 

 of parasites {Euzenilliopsis diutraw, Bassus stigmaterus, and Apanteles sp.) 

 for the cfintrol of Dlatra'M saccharalis, based upon data presented in the bulletin 

 previously noted (E. S. K., 41. p. 60). 



A new species of the serphidoid genus Dendrocerus, A. B. Gahan {Proc. 

 Ent. Soc. Wash., 21 {1919), No. 6, pp. 121-'123). — Dendrocerus conwentzice 

 reared from Cowwentzia liageni at Amherst, Mass., and D. conwentsice rufus 

 li'om cocoons of Conwentsia sp., at Felida, Wash., are described as new. 



Description of a new cynipoid from Trinidad, S. A. Rohwer {Proc. Ent. 

 Soc. Wash., 21 {1919), No. 6, p. 15G). — Blglyphoscma anastreplue reared from 

 Anastrepha sp., Trinidad, British West Indies, is described as new, 



FOODS— HUMAN NUTRITION. 



The nutritive value of the wheat kernel and its milling products, T. B. 

 Osborne. L. B, Mendel et al. (Jour. Biot. Chem., 37 {1919), No. J,, pp. 557-601, 

 pis. 11, figs. 3). — A detailed study is presented of the comjjositlou and nutritive 

 value of the wheat kernel and its milling protlucts, with special reference to 

 the problems raised by modern milling methods and the degree to which it is 

 desirable to mill flour for general use. The literature on the composition of the 

 embryo, seed coats or bran, endosperms, and w^hole wheat kernel is reviewed, 

 and data compiled from the literature and from original studies are presented. 



The principal experimental work reported is an extensive series of investiga- 

 tions on rats for the purpose of cuiupuriug quantitatively the entire wheat
