662 EXPERIMENT STATION RECORD. 



appearance of adults in spring in the Department of Herault, and tlieir feeding 

 habits and reproductive capacity. 



Annual reports of the Royal Sericultural Station, Padua (Ann. R. Staz. 

 Bacol. Padova, 37 {1010), pp. Ill, figs. 6; 38 {1911), pp. 160, pis. 6, figs. 6).— 

 These reports contain papers by E. Verson and E. Bisson and by E. Quajat on 

 the sillvworm and silk cultui'e. Bibliographies of the literature relating to seri- 

 culture that were published during the years 1908-9 (pp. 99-117) and 1909-10 

 (pp. 135-159), respectively, and here presented, were prepared by E. Bisson. 



Illustrations of diurnal Lepidoptera, A. G. Weeks, Jr. {Boston, 1905, vol. 

 1, pp. XII+117, pis. 45; 1911, vol. 2, pp. XVI+37, pis. 2i).— Volume 1 of this 

 work consists of colored plates and descriptions of 81 species, largely from 

 Bolivia, which the author has found to be new to science. An account by W. J. 

 Gerhard of a 60 weeks' collecting trip in that country is incorporated in the 

 work. 



Volume 2 is confined to descriptions and colored plates of species taken in the 

 neighborhood of Suapure River in Venezuela. A list of the scientific writings 

 of W. H. Edwards is included. 



The importation into the United States of the parasites of the g'ipsy 

 moth and the brown-tail moth: A report of progress with some considera- 

 tion of previous and concurrent efforts of this kind, L. O. Howard and W. F. 

 FiSKE {V. S. Dept. Agr., Bur. Eat. Bui. 91, pp. 312, pis. 28, figs. 7//).— In the 

 first part of this detailed report the authors consider previous work in the 

 practical handling of natural enemies of injurious insects, early ideas on intro- 

 ducing the natural enemies of the gipsy moth, the circumstances which brought 

 about the actual beginning of the work, the known and recorded parasites of 

 the gipsy moth and brown-tail moth, establishment and dispersion of the newly 

 introduced parasites, disease as a factor in the natural control of the gipsy 

 and brown-tail moths, studies in the parasitism of native insects, and parasit- 

 ism as a factor in insect control. 



Attention is next given (pp. 109-131) to the gipsy moth, its rate of increase 

 in New England, the amount of additional control necessary to check its in- 

 crease in America, the extent to which it is controlled through parasitism 

 abroad, and the sequence of its parasites in Europe. Then follow accounts 

 (pp. 132-168) of the brown-tail moth and its parasites in Europe, parasitism 

 of the gipsy and brown-tail moths in America, the importation and handling 

 of parasite material, and the quantity and localities from which the parasite 

 material has been received. 



The remainder of the bulletin is largely devoted to specific consideration of 

 the various parasites and hyperparasites of the 2 moths. The bulletin closes 

 with a summarized account of the present status of the introduced parasites 

 and of developments of the year 1910. 



Formalin poison for flies, R. I. Smith (Bui. N. C. Bd. Health, 26 {1911), 

 No. 2, p. 71). — The author has used milk with formalin, at the rate of 16 oz. 

 of equal parts milk and water to 1 oz. of formalin, with excellent results. 

 This mixture is said to attract flies much better than when the formalin is used 

 in sweetened water. 



Control of the apple maggot by picking up drops, W. O. O'Kane {Jour. 

 Econ. Ervt., Jf {1911), No. 2, pp. 173-179, figs. //). — A more detailed account of 

 the author's investigation on the subject than that previously noted (E, S. R., 

 25, p. 356). 



The apple maggot or "railroad worm," W. C. O'Kane {New Hampshire 

 Sta. Circ. H, pp. k, figs. 2). — This circular, based on investigations previously 

 noted (E. S. R., 25, p. 356), calls attention to the methods by which the in- 

 festation of the apple maggot can be checked.
