been previously noted (E. S. R., 29, p. 559; 30, p. 361), is here described under 

 tiie headings of salt marsh and inland or local mosquito work. 



A remarkable outbreak of Culex pipiens, W. E. Beitton (Jour. Ecan. Ent., 

 7 (1914), A'O. 3, pp. 257-260). — ^This article records the development of the rain 

 barrel mosquito in edges of a stream at New Haven, and in ponds in the 

 vicinity of Greenwich from which fish had been driven by mill waste, includ- 

 ing dyestuffs. etc. 



Diptera. — Family Cecidomyidae, J. J. Kieffee (P. Wyts)7ian's Genera 

 Inscctoruin. Brussels, I'JIS, Xo. 152, pp. 346, pis. 15; rev. in Ent. News, 25 

 (1914), No. 4, pp. 185-188).— This work lists some 2,500 species and 330 genera 

 from all parts of the world. The review is by E. P. Felt. 



The Hessian fly situation in Kansas, G. A. Dean and J. W. McColloch 

 {Kansas Sta. Circ. 37 {1914), PP- 4, fids. 3). — A brief popular account based on 

 studies reported in Bulletin ISS. previously noted (E. S. R., 30, p. 157). 



Ceratopogoninae sucking' the blood of caterpillars, F. Knab (Proc. Ent. 

 Soc. Wash., 16 {1914), No. 2, pp. 63-66). — Following a review of the literature 

 relating to the subject the author pi-e.sents a description of two new species, 

 namely, Forcipomyia crucicida from Florida and F. crudelis from Mexico. 



The sandfly and pellagra, III, S. J. Huntee {Jour. Econ. Ent., 7 {1914), 

 ^0. 3, pp. 293, 294). — A brief summary of progress in continuation of the 

 work previously noted (E. S. R., 29. p. 357). 



Experiments with house fly baits and poisons, A. W. Morrill (Jour. Econ. 

 Ent., 7 {1914), No. 3, pp. 268-274). — Among the more important conclusions 

 drawn from the exi)eriments conducted are the following : 



" Vinegar in itself is an excellent bait for a fly trap, but when used with 

 sugar or bread its attractiveness to flies is greatly increased. Equal parts of 

 vinegar, sugar, and water appear to be approximately as attractive as equal parts 

 of sugar and vinegar. An attractive combination poisonous to flies can be made 

 with formalin and vinegar, but further tests are necessary to determine the 

 best proportions. Formalin (40 per cent) diffei's greatly on different days in 

 its attractiveness to flies. This variation is evidently not due directly to tem- 

 perature conditions, and it suggests the possibility of the flies themselves dif- 

 fering from day to daj' in the degree of the sensitiveness of the sensory or- 

 gans. . . . Beer, milk, and bread, in the order named, are excellent materials 

 to use with formalin, increasing its attractiveness many times. . . . Commer- 

 cial alcohol (95 per cent) and water at the rate of 1 : 20 appears from the ex- 

 periments to be of about equal value with formalin and water mixed at the 

 rate of 1 : 10. both as to attractive power and killhig effects." 



Further observations on the breeding habits and control of the house fly 

 (Musca domestica), C. G. Hewitt {Jour. Econ. Ent.. 7 {1914), No. 3, pp. 

 281-293, figs, i?).— This preliminary report of investigations carried on during 

 the summer of 1913 is presented primarily with a view to drawing the atten- 

 tion of other workers to the need of experimental work along similar lines. 



Report of an expedition to Africa in search of the natural enemies of 

 fruit flies (Trypaneidae) with descriptions, observations, and biological 

 notes, F. Silvestri iBd. Coinrs. Agr. and Forestry Haicaii. Div. Ent. Bui. 3 

 {1914), pp. 176, pis. 25, fig. i).— The first part of this report (pp. 13-40) con- 

 sists of the itinerary of the journey in which the Canary Islands, Senegal, 

 French Guinea, Southern Nigeria, Kamerun, Gold Coast, Dahomey, Congo, 

 Angola, South Africa, Australia, and Honolulu were visited. This is followed 

 (pp. 41-96) by an account of the fruit flies observed during the expedition in 

 Africa, which includes 10 species of Ceratitis, namely, Ceratitis eapitata. C. gif- 

 fardi, C. silrestrii, C. stictiea antistictica, C. punctata, C. anonw, C. colce, C. ruH-
