occurred over the greater part of the districts from Chancay to Casma, reach- 

 ing the latter valley on March 5. 



The tachinid parasite Eucelatoria australis was found commonly in the 

 fields in April. 



The sugar-cane tingid from Mexico, O. Heidemann (Jour. Econ. Ent., 6 

 {1913), No. 2, pp. 2Jf9-251, fig. 1). — The author presents a description of 

 LeptoiUctya tabida. 



Itonida anthici n. sp., E. P. Felt (Jour. Econ. Ent., 6 {1913), No. 2, pp. 278, 

 279). — This gall fly is said to produce clustei-s of pinkish white, flowerlike 

 galls on cypress. Taxodium disUchum, in Arkansas, INIississippi, and Alabama. 

 It is stated that the galls are sometimes so numerous as to dominate the dark 

 green cypress foliage and give the appearance of an ordinary flowering plant 

 thickly set with small blossoms. 



Notes on the wheat fly (Contarinia tritici), with special reference to its 

 depredations in central Sweden during the summer of 1912, E. Henning 

 {Srerujes Utsddesfdr. Tidskr., 23 {1913), No. 1, pp. 65-81, figs. 16).— Data 

 showing the localization of the larvae of the insect in the wheat head and the 

 percentage of affected plants of different varieties at Ultuna and other places 

 in central Sweden are presented. Possible preventive measures are also dis- 

 cussed in the paper. 



Bleeding trees, E. P. Felt {Jovr. Econ. Ent., 6 {1913), No. 2, pp. 285, 286).— 

 Numerous larvae, superficially resembling Sciara but probably referable to the 

 genus Ceratopogon, were found in sap originating from a crevice in the trunk 

 of a sugar maple at Kinderhook, N. Y. The point below the injury was brown, 

 corrugated, and seemed to be covered with precipitates from the sap. An 

 examination of the cavity showed the larva; to be present in the deepest portion 

 of tlie crevice, where they apparently kept the tissues in a constant state of 

 irritation. The sap issuing from a similar wound on a horse chestnut trunk 

 was inhabited by probably identical larvse. 



Pellagra and the sand-fly, II, S. J. Hunter {Jour. Econ. Ent., 6 {1913), 

 No. 1, pp. 96-101). — This is a report of the work carried on in Kansas in 1912 

 in continuation of that previously noted (E. S. R., 26, p. 656). 



The mosquitoes of North and Central America and the "West Indies, L. O. 

 Howard, H. G. Dyak, and F. Knab {Carnegie Inst. Washington Pub. 159, 1912, 

 vols. 1, pp. VII +520, pis. Ui, figs. 6; 2, pp. X, pis. 150).— This work is based on 

 investigations commenced in January, 1903. The first volume deals with early 

 accounts of mosquitoes; the structure and habits of adults, larvse, and pupre ; 

 natural enemies; collecting, mounting, and rearing; the relation of mosquitoes 

 to man ; economic loss from mosquitoes ; examples of mosquito control ; a bibli- 

 ography ; and an index. 



The second volume consists of plates illustrating the morphology of mosqui- 

 toes as dealt with in volume 1. 



Preliminary note on the finding of Hypoderma bovis at Agassiz, B. C, 

 together with notes on the biology of the fly, S. Hadwen {Proc. Brit. Gohwi- 

 hUi Ent. Soc, 1912, pp. 81, 82; abs. in Rev. Appl. Ent., 1 '{1913). Ser. B, pt. 3, 

 p. 60). — The author reports that during the summer of 1912, 6 specimens of 

 H. bovis were captured while attacking cattle and 7 flies bred from their puparia. 

 This is said to be the first record of the occurrence of the species in Canada and 

 probably for North America. 



On the influence of the metamorphosis of Musca domestica upon bacteria 

 administered in the larval stage, H. Tebbutt {Jour. Hyg. [Cambridge^, 12 

 (1912), No. 4, PP- 516-526). — "Pathogenic organisms such as Bacillus dysen- 

 terice (type 'Y') can not be recovered from pupae or imagines reared from
