nf these butterflies. When the pupae were kept in an abnormally hoi and dry atmos- 

 phere they all died. Similarly n<> success was had in rearing larvae when kept at a 

 temperature of 80° F. in an atmosphere saturated with moisture. Preliminary 

 experiments were carried out in keeping pupae at temperatures of 55 and 65° F. by 

 means of ice. The results of these experiments are not yet apparent. 



The control of the boll weevil, including results of recent investigations, 

 \V. D. Hunter ( U. S. Dept. Agr., Farmers' Bid. 216, pp. S3, figs. 5).— This bulletin 

 was prepared to replace Fanners' Bulletin No. 189 already noted | E. S. R., 15, p. 

 879). rt contains a restatement of the previous recommendations of the Bureau of 

 Entomology regarding tin- means of controlling the boll weevil, together with an 

 account of more recent work which has substantiated those recommendations, an 

 account of a variety test of cotton, the present territory infested by the hull weevil, 

 and State quarantine laws against the importation of the boll weevil. Such laws 

 now exist in Alabama, Georgia, Louisiana, Mississippi, North and South Carolina, 

 and Oklahoma. Suggestions are made regarding the desirability of the uniform 

 State law for the control of the boll weevil. Observations were made on the Mexi- 

 can tree cotton, during which it was found that this species was not immune to 

 weevil attacks. 



The cotton boll weevil, W. W. FkoggAtt {Agr. Gaz. New South Wales, 16 {1905), 

 No. /, pp. 23-25, figs. 2). — Xotes are given on the habits, life history, and injurious 

 attacks of this species. The possibility of its being introduced into Australia is 

 suggested. 



The method of rearing the natural enemy of the cotton boll weevil on a 

 large scale, A. L. Herrera (Mem. y Rev. Soc. dent. "Antonio Alzate," 19 {1904), 

 Xo. 11-1 .', jiji. .127-331).— A mite resembling thechicken mite was discovered infest- 

 ing the Mexican cotton boll weevil. Experiments were made in devising a suitable 

 semifluid nutrient media in which this mite could be artificially reared in large 

 numbers and scattered upon infested cotton plants. Considerable success has been 

 had along this line. 



The Hessian fly {Bd. Agr. and Fisheries [London], Leaflet 125, pp. 3, figs. 7). — 

 This insect is described and notes are given on its food plants, life history, and treat- 

 ment. It is recommended that screenings be burned or utilized so as to prevent the 

 development of the flaxseed stage of the Hessian fly. The use of fertilizers may 

 also stimulate the crop so as to enable it to endure the attacks of the Hessian fly 

 more successfully. Winter wheat should lie sown late, so as to avoid the autumn 

 attack of the pest. 



The fruit fly (Ceratitis capitata), C. W. Mally {Agr. Jour. Cape Good Hope, 

 .!■', [1904), No. o\ pp. 647-662, ,pl. I, fig. 1). — This pest is most injurious to peaches 

 and apricots. It was apparently brought to Cape Colony from Madeira. Detailed 

 notes are given on the habits, life history, and food plants of the insect, together with 

 a description of the pest in its various stages. A large number of natural enemies of 

 this insect have been observed, including birds, spiders, wasps, and internal parasites. 

 In controlling the pest, the collection and destruction of fallen fruit, at least once 

 daily, are recommended, together with thorough cultivation of the soil, clean picking 

 of the fruit, and the use of nets to prevent the insects from depositing their eggs 

 in the fruit. The use of poisoned bait was tested and encouraging results were 

 obtained. This method will be further tested for the purpose of determining its 

 practical efficiency. It is believed that there is little hope of efficient aid from the 

 natural enemies of the pest. 



The greenhouse white fly, A. W. Morrii.l {U. S. Dept. Agr., Bureau of Ento- 

 mology Circ. 57, pp. :>, tig. 1 ). — The damage caused by this insect is outlined, together 

 with notes on its origin, distribution, food plants, and appearance in various stages. 

 It may usually be readily distinguished from Aleyrodes citri ami .1. packardi. The 

 remedy recommended as most efficient in destroying this pest is fumigation with
