60 EXPERIMENT STATION RECORD. 



Massachusetts Station Bulletin SS and are here arranged under 9 genera, 137 

 species, and 22 varieties. 



Formalin as a reagent in the preparation of some soft-bodied Coccidae, 

 E. E. Green (Ent. Mo. Mag., 2. ser., 17 (1906), A'o. 19S, pp. 129, 130}.— Some 

 difficulty has been experienced in preserving C'occidie, especially the soft-bodied 

 species, for subsequent study. The chitin of the skin often fails to hold its 

 form, and the dermal cells and other characteristic features may become oblit- 

 erated. The author accidently discovered that formalin in a 3 per cent solution 

 preserves these features in excellent condition. 



The bionomics of grain weevils, F. J. Cole (Joiii: Econ. Biol.. 1 (190G). A'o. 

 2, pp. 63-11). — The exiierinients reported in the present paper were made on 

 the common grain and rice weevils. It appears that moistui'e under a temper- 

 ature of 80° F. is favorable to the life of adult grain weevils but that the tem- 

 perature of 80° F. without the moisture is quite fatal to the beetles. A non- 

 ventilated atmosphere at a temperature of 80° F. charged with water vapor 

 furnishes favorable conditions for the life of the beetles. Experiments in 

 withholding oxygen from the beetles indicate that they may thrive well in an 

 atmosphere containing SO per cent of carbon dioxid. It is obviously impossible 

 therefore to destroy them by preventing ventilation. 



Animals injurious to sugar beets, J. Jablonowski (A czukorrcpa dUati 

 rll<'n.sr(/('i. liitiUtiicst : 11 uiH/ariuii .s'h//«/- Beet Assoe.. 1906, pp. 288, flgs. 65). — 

 The sugar beet industiy of Hungary is of sufficient importance to justify an 

 elaborate study of the insect enemies of this plant. The author has made 

 observations on the important insect enemies of sugar beets, and in the present 

 volume presents the results of his study, together with the results of other 

 investigators who have worked along the same line. The insects discussed in 

 the volume include a long list of species injurious to the various parts of the 

 sugar beet. Myriapods, mites, and related species of animals are discussed. 

 Among the more important insects mention may be made of Cleonus puncti- 

 veniris, C. pedestris, Hultiea oleracea, various species of wireworms. Aphis 

 papaveris, caterpillars injurious to leaves, especially webworms, Pegomyia 

 hyoseiiami, related species of maggots, etc. 



Insect pests of cotton in India, 11. Maxwell-Lefroy {Agr. Jour. India, 1 

 (1906), Ao. 1, pp. .'i9-61, pl.t. //). — On account of the large annual production of 

 cotton in India the insect pests of this crop assume considerable economic 

 importance. In the present article particular attention was given to cotton 

 aphis, Dijsderviis einguJutus, bollworms (Gelechia gosxypieUa, E(tri<is, fabia. 

 and E. insulana), cotton-stem borer, and cotton-stem weevil. These pests are 

 considered the most important ones affecting cotton in India, and it is estimated 

 that they cause the destruction of about one-tenth of the crop. Fortunately the 

 remedies for these ])ests are comparatively simple, and the main problem in the 

 control of the insects consists in educating the natives of India so that they will 

 recognize the nature of the pests and the necessity for taking some insecticide 

 measures. 



The principal insects attacking the cocoanut palm, II. C. S. Banks (Philip- 

 pine Jour. Nei., 1 (1906), No. 3, pp. 211-228, pis. 10).— In the present paper the 

 author discusses certain species of lepidoptera and coccidas which attack the 

 cocoanut palm. In this account particular attention is given to Thosea 

 cinereamarginntn. I'ndranna chrysozonu. Aspidiotus destructor, etc. It is sug- 

 gested that spraying witli linie-sulpliur wash or kerosene emulsion would serve 

 to protect young cocoanut trees against attacks of scale insects. 



Moth borer in sugar cane, maize, and sorghum in western India, II. ]Max- 

 well-Lefroy (Agr. Jour. India, 1 (1906), No. 2, pp. 91-11.',, pU. 2). — A number 

 of insects are commonly referred to as moth borers of the sugar cane, but the
