in New Hampshire and T. euproctidis reared from the eggs of Euproctis con- 

 spersa Butl. in Japan, are described as new. 



The North American ichneumon flies of the tribe Acoenitini, R. A. CusH- 

 MAN and S. A. Rohweb (Proc. U. S. Natl. Mus., 57 {1920), pp. 50S-52S, figs. 

 S). — Of the five genera belonging to this tribe, the only two, Coleoceutrus and 

 Arotes, known to occur in our region, are treated at length. 



Holarctic tribes of the ichneumon flies of the subfamily Ichneumoninae 

 (Pimplinsp), R. A. Cushman and S. A. Rohwer {Proc. V. S. Natl. Mus., 5? 

 {1920), pp. Sl<)-S96, figs. 11}). — This paper is a result of studies extending over 

 a period of seAeral years, and embodies the opinion of the authors as to the 

 relationship and number of tribes of the Iclineumoninae (Pimplinse, authors) 

 as represented in the Holarctic region. 



Description of an Apanteles parasite of Pionea forficalis, C. Gautieb and 

 P. RiEL {Bul. Soc. Ent. France, No. 11 {1919), pp. S09-3i2).— Under the name 

 A. gabrielis, the author describes a braconid which parasitizes nearly 50 per 

 cent of the caterpillars of P. forficalis L., an important enemy of cabbage. 



The parasites of Pyrausta nubilalis Kb. in France, A. Vuillet {Bul. Soc. 

 Ent. France, No. 17 {1919), pp. S08-309 ; abs. in Rev. Appl. Ent. 8 {1920), Ser. 

 A, No. S, p. 120). — Investigations conducted in France have shown the Euro- 

 pean corn borer to be parasitized by the tachinids Pnraphorocera senUh Rond., 

 and Lydella stahulans Mg. Two unidentified ichneumonids were also found to 

 attack it. 



On the pleophagy of the insect-attacking fungus Metarrhizium aniso- 

 plia? (Metsch.) Sor., K. Friedekichs {Centbl. Bakt. [eic], 2. Abt., 50 {1920), 

 No. 13-19, pp. 335-356). — This paper includes a report of the experimental in- 

 fection of a number of different insects by this fungus parasite, and a bibliog- 

 raphy of 48 titles. 



FOODS— HUMAN NUTRITION. 



A chemical study of frozen flsh in storage for short and long periods, 



E. D. Clark and L. H. Almy {Jour. Indus, and Engin. Chem., 12 {1920), No. 7, 

 pp. 656-663). — This contribution from the Bureau of Chemistry, U. S. Depart- 

 ment of Agi-iculture, consists of the detailed report, with analytical data, of 

 the chemical study of frozen fish made in the course of the investigation of the 

 commercial freezing and storing of fish previously noted (E. S. R., 39, p. 165). 



Two species of salt water flsh, bluefish {Pomaiomus saltatrix) and weakfish 

 {Cynoscion regalis), were frozen, stored in a holding room at 15° F., and exam- 

 ined after different storage periods for appearance, gross analysis, nitrogenous 

 constituents, and constants of fat extracted from the flesh. The bluefish were 

 eviscerated before freezing and were kept glazed with a thin covering of ice 

 during the storage period. The weakfish were divided into four lots, unglazed, 

 eviscerated, stored without wrapping ; glazed, eviscerated, stored without wrap- 

 ping; unglazed, eviscerated, with paper wrapping; and glazed, uneviscerated, 

 and without wrapping. 



As noted in the previous publication, the fish protected by the thin ice glaz- 

 ing kept nmch better than the unglazed fish even when the latter were pro- 

 tected by a paper covering. Both bluefish and weakfish stored in a glazed con- 

 dition remained palatable during storage for 16 and 13 months, respectively, 

 while unglazed, unwrapped weakfish dried out so rapidly that it was considered 

 unmarketable at the end of 4 montlis. Glazed uneviscerated weakfish kept 

 practically as well as glazed eviscerated fish. All samples became unpalatable 

 after 2 years of storage.
