Gouty pine midge (Itonida inopis), E. P. Felt {Jour. Econ. Ent., 6 {191S), 

 No. 3, p. 331). — Observations indicate that under certain conditions this midge 

 may be of some economic importance, even thongli its host plant, the scrub pine 

 {Pinus rigida). is not one of the most valuable trees. 



Device for detecting flight of mosquitoes, L. E. Haskell (Sci. Amer., 109 

 {1913), No. 5, p. 102, flg. 1). — This is a desci-iption of an instrument invented 

 by E. F. Quimby which has been used with success in the Isthmian Canal Zone. 

 The device consists of a metal frame holding 4 glass plates, each 12 by 12 in. 

 in size, placed at right angles to one another upon a tripod. In order to catch 

 the mosquitoes a coat of tanglefoot composed of I lb. of rosin to 1 liter of castor 

 oil is prepared, and when applied to the glass is practically transparent. 



Determining the flight of mosquitoes, J. Zetek {Ann. Ent. 8oc. Amer., 6 

 {1913), No. 1, pp. 5-21, figs. Jf) . — A general discussion of methods. 



The yellow-fever mosquito (Aedes calopus), L. O. Howakd ( JJ. 8. Dept. Agr., 

 Farmers' Bui. SJfl, pp. 16, figs. 6). — This popular account discusses the domes- 

 ticity of the species, habits of the adult, breeding habits, geographical distri- 

 bution, etc. 



The reduction of domestic flies, E. H. Ross {London, 1913, pp. VIII +103, 

 pis. 15, figs. 2). — This work discusses such topics as the importance of domestic 

 flies, their life history, habits, and enemies, how to reduce flies, and sanitary 

 education. 



The sheep maggot fly pest in Australia, W. W. Feoggatt and W. F. Cooper 

 (Watford, England: Cooper Lah. Econ,. Research, 1913, pp. XI+88, figs. IS). — 

 This work consists of 4 parts. Part 1 presents a general summary of scientific 

 information on blow flies, including their biology and natural enemies. Part 2, 

 by W. W. Froggatt (pp. 10-48), deals with the maggot fly in sheep, including 

 symptoms and method of infestation, the flies that cause the damage, blow flies 

 including the genera Calliphora, Lucilia, and Ophyra, the causes that have led 

 to scavenger or flesh flies becoming parasites, docking the tails of lambs, meth- 

 ods of control, etc. ( See also a previous note, E. S. R., 24, p. 757. ) Abstracts of 

 papers by J. L. F. Woodburn (pp. 49-54) and by A. E. McLeod and J. B. Holme 

 (pp. 55, 56) then follow. Part 3 (pp. 57-72) is devoted to remedial measures, 

 and part 4 (pp. 73-75) takes up the question of when is the pest most serious. 

 A list of authors of essays on the subject and specimens received, a bibliography 

 of the more important papers, and an index are appended. 



A historical account on the use of kerosene to trap the Mediterranean fruit 

 fly (Ceratitis capitata), H. H. P. and H. C. Sevebin {Jour. Econ. Ent., 6 {1913), 

 No. 4, pp. 347-351, fig. 1). — The authors first present the results of experiments 

 carried on in attempting to control the Mediterranean fruit fly by means of 

 kerosene traps, and then give a historical account of the method of control as 

 practiced or recommended in various jaarts of the world. 



" The attempt on our part to control the Mediterranean fruit fly by the use 

 of kerosene traps wired to fruit trees was a complete failure. In one experi- 

 ment 10 traps were wired in 10 fruit-bearing citrus trees located in different 

 parts of an orchard and in 5 weeks, 10,239 fruit flies were captured; of this 

 entire number only 36 were females, the remainder being males. At the end 

 of the 5 weeks nearly every ripe orange in this orchard had been ' stung ' by 

 the pest." 



Fruit fly control, W. R. Winter {Bermuda: Dept. Agr., 1913, pp. 14; ahs. in 

 Rev. Appl. Ent., 1 {1913), Ser. A, No. 5, p. 164). — The author gives a brief state- 

 ment of the life history of and damage d«ne by Ceratitis capitata, with a list 

 of 45 trees attacked by the fly, to which grapes and mulberries must occasion- 

 ally be added. The most efficient control in Bermuda has been found to lie
