466 EXPERIMENT STATION RECORD. [Vol. 38 



applicatious of arsenical sprays, either arsenate of lead or zinc arseuite at the 

 rate of 1 or 2 lbs. (powder) to 50 gal. of water. 



Results obtained from spraying raspberries with carbolineum for (Lam- 

 pronia) Incurvaria rubiella, K. Onrust (Tijdnchr. Flantenziekten, 23 {1911), 

 No. 1, pp. n-30; abs. in Rev. Appl. Ent., Scr. A, 5 (1911), No. 7, p. 277).— 

 Spraying with carbolineum or banding with adhesive has been found to be 

 the best measure for controlling infestation by this tineid moth borer, which 

 sometimes infests the raspberry in the Netherlands to the extent of 50 per 

 cent. An 8 per cent strength of carbolineum should be applied to the foliage 

 and roots before March 15. 



The toxin of Sotto bacilli, K. Aoki and Y. Chigasaki (Bui. Assoc. S6ri. 

 Japon, Nos. 20 (1916), pp. 1-6; 21 (1917), pp. J-8).— These data supplement the 

 accounts previously noted (B. S. R., 37, p. 853). The toxin of the Sotto 

 bacillus largely remains fixed within the organism ; it does not pass through the 

 porcelain filter and disappears after boiling for 10 minutes. The spores are 

 destroyed and the toxin neutralized by Lugol's solution. 



Studies in Philippine Diptera, I and II, M. fiEzzi (Philipijine Jour. ScL, 

 Sect. D, 8 (1913), No. 4, pp. 305-332; 12 (1917), No. S, pp. 107-161, pi. D.—A 

 catalogue of r>iptera hitherto recorded from the Philippine Islands is first 

 presented, followed«by descriptive notes on 200 forms. In the first and second 

 papers, respectively, 2 genera and 17 species and 2 genera and 34 species are 

 described as new. 



The Hessian fly, E. N. Coey (Md. Agr. Ext. Serv. Bui. 7 (1917), pp. 4, 

 fig. 1). — A summary of information on this pest, including a diagram of its 

 seasonal development and the planting dates between which it is safe to sow 

 wheat in various parts of Maryland. 



Sheep mag'got flies. III, W. W. and J. L. Froggatt (Dept. Agr. N. S. Wales, 

 Farmers' Bui. 113 (1917), pp. 37, figs. i2).— This report of work, carried on 

 during 1915-16 in continuation of that previously noted (E. S. R., 37, p. 160), 

 deals with the reduction of flies by destruction of offal and carrion, trapping 

 flies, blow flies breeding in decaying vegetable matter, baits for attracting and 

 poisoning maggots and adult flies, tests with dips and dressings, chemical 

 notes, dipping and spraying, rendering sheep immune by internal drenches or 

 licks, notes on destruction of birds, and climatic conditions that seem to suit 

 sheep maggot flies in the Riverina. In the first of two appendixes (pp. 27-33) 

 the parasites of the sheep maggot flies, including Nasonia hrevicornis which 

 has been reared and distributed all over New South Wales, Chalcis calliphoi-^p 

 (E. S. R., 36, p. 360), and an undetermined parasite of the shining black fly 

 (Ophyra nigra), are dealt with. Appendix 2 (pp. 34-37) discusses an amended 

 classification of the sheep maggot flies dealt with in these reports, with some 

 account of their identification. 



Life history, habits, natural enemies, and methods of control of the cur- 

 rant finiit fly (Epochra canadensis), H. H. P. Severin (Maine Sta. Bui. 26Jt 

 (1917), pp. 177-247, pis. If, figs. 7).— This is a summary of the present status of 

 knowledge of the currant fruit fly, based upon a review of the literature and 

 investigations conducted by the author in Maine. Following a brief introduction 

 the subject is dealt with at length under the headings of systematic position, 

 distribution and destructiveuess, life history, habits and behavior of adults, 

 natural enemies, and methods of control. A bibliography of 62 titles and an 

 index are included. 



The species appears to be confined to North America ; in Canada, it is dis- 

 tributed principally in the Canadian zone as far north as Edmonton, Alberta ; 

 and in the United States it occurs in the Canadian, Transition, and Upper Aus-
