iu Siberia and Russian Turkestan, and to have been imported to the United 

 States, where it was first found in 18G9 and where it caused considerable dam- 

 age to the beet crops in 1909 and 1910. A detailed report of its life history 

 and remedial measures is given. 



Serious outbreak of Phlyctaenodes sticticalis near Poltava, N. X. Kuud- 

 JUMOV {Khutorianin, No. 26 (1913), pp. 697, 698; abs. in Rev. Appl. Ent., 1 

 {1913), 8er. A, Xo. 10, p. 394). — ^ brief discussion of outbreaks of this pest 

 with recommendations as to remedial treatment. A detailed account of this 

 Itest is given In the article above. 



The codling moth in Uruguay, E. Lahille (Rev. Asoc. Rural Uruguay, 42 

 (1913), No. 8-9, pp. 645-648; abs. in Rev. Appl. Ent., 2 (1914), Ser. A, No. 3, 

 p. 162). — The author states that in Uruguay adult codling moths are destroyed 

 by bonfires lit in the evening around pear and apple trees when in blossom. 



A small manual on malaria, L. M. Pabrot (Petit Manuel du Paludisme. 

 Paris, 1914, PP- 32, figs. 11). — This work, which is intended for the use of 

 schools in North Africa, gives information on the nature of the malarial para- 

 site and of the mosquito and its role in the transmission of the parasite and 

 means of combat. 



Mosquitoes and malaria, J. C. Faube (Agr. Jour. Union So. Africa, 7 (1914), 

 No. 2, pp. 223-242, figs. 13). — This is a general discussion of the subject. 



A synopsis of the described North American species of the dipterous 

 genus Tipula, W. G. Dietz (Ann,. Ent. Sog. Amer., 6 (1913), No. 4, pp. 461- 

 484)- — The synopsis here presented is in tabular form. A list with habitat and 

 bibliography of the North American species described since the publication of 

 Aldrich's Catalogue of North American Diptera is appended. 



Heredity of bristles in the common greenbottle fiy, Lucilia sericata. — A 

 study of factors governing distribution, P. W. Whiting (Amer. Nat., 48 

 (1914), No. 570, pp. 339-355, fig. 1). — "Taking a general summation of all the 

 bred material of L. sericata, we find that re<:luction affects the males while 

 addition affects the females. Of the 5,367 flies bred, 2,708 are males and 2,659 

 are females, giving practical equality. Reduction in the males is 748.5 bristles, 

 while in the females it is only 455.5 bristles. As has been noted before, the 

 degree of reduction in the females is increased by the later generations of 

 strain 1913-A, by reason of the fact that reduction rarely goes, beyond the loss 

 of two bristles in a single fly. Thus when most of the flies of a population 

 become reduced to this extent it is evident that reduction in the males would 

 be but slightly in advance of that in the females. 



" There are 210 bristles added in the males, while there are 343 added in 

 the females. Thus addition affects the females more than the males. These 

 figures for bristles added represent number of bristles, and thus no distinction 

 is made between bristles of large and bristles of small size." 



The skin maggot of man, C. Fuller (Agr. .Jour. Union So. Africa, 7 (1914), 

 No. 6, pp. S66-874. fig- 1)- — This paper relates to Corrli/lohia anthropophaga. 



An attempt to transmit poliomyelitis by the bite of Lyperosia irritans, 

 E. Francis (Jour. Infect. Diseases, 15 (1914), No. 1, pp. 1-5, figs. 2). — In 

 several experiments conducted flies (L. irritans) that had sucked the blood of 

 infected rhesus monkeys twice daily for periods of four and sis days from 

 the time of their inoculation with poliomyelitis virus to their death and were 

 allowed to feed on healthy rhesus monkeys twice daily during the same periods 

 and two or three times daily during i>eriods ranging from six to eight days 

 following, failed to transmit the disease. 



Flies in relation to disease. — Nonbloodsucking flies, G. S. Graham-Smith 

 (Rev. in Science, n. ser., 39 (1914), No. 1.013, pp. 787-789).— X review by L. O. 

 Howard of the work previously noted (E. S. R., 30, p. 552).
