748 EXPEEIMENT STATION EECOED. 



Catalogue of recently described Coccidse, V, E. R. Sasscer (Proc. Ent. Soc. 

 Wash., 17 (1915), No. 1, pp. 25-S8).— This fifth part of the catalogue previously 

 noted (E. S. R., 28, p. 754) is thought to be fairly complete to November, 1914. 



On the occui-rence of an intermediate in Aphis pomi, W. F. Tukneb and 

 A. C. Baker (Proc. Ent. Soc. Wash., 11 (1915), No. 1, pp. 42-52, figs. 18).— A 

 discussion of aphidid forms. 



The authors conclude that " in these intermediates we have to do solely with 

 transitional forms between more primitive conditions on one hand and more 

 advanced conditions on the other. We feel confident also that all these inter- 

 mediates are of equal value. The very fact that variants have been discovered 

 in so many different species, having such diverse habits, seems to us to preclude 

 the possibility that these arise from different fundamental causes. The only 

 difference is that the forms in A. pomi and similar species and the intermediate 

 sesuparge of various Phylloxera are varying in one characteristic, the elimina- 

 tion of wings, while the virginoparous forms in Phylloxera vastatrix and in the 

 Chermesiuse are varying in two characters, the elimination of wings and the 

 elimination of sexes." 



Further studies of the embryology of Toxoptera graminum, W. J. Phillips 

 (U. S. Dept. Agr., Jour. Agr. Research, Jf (1915), No. 5, pp. 403, 404, pls. 2).— 

 This paper supplements the general account of the development of the winter 

 eggs of T. graminum given in the bulletin by Webster and Phillips, previously 

 noted (E. S. R., 27, p. 859). 



A catalogue of Portuguese aphidids, J. S. Tavabes (Broteria, Ser. Zool., 12 

 (1914), No. 3, pp. 177-193, figs. 8; abs. in Rev. Appl. Ent., 3 (1915), Ser. A, No. 

 2, p. 90). — Eighty-nine species are recorded together with their food plants and 

 the localities in which they have been collected. 



Ravages of the forleule (Panolis piniperda) in the Wolesclina woods in 

 1913, Nechleba (Vereinsschr. Forst, Jagd, u. Naturlc, Prague, No. 11-12 (1914), 

 pp. 614-633, fig. 1; abs. in Rev. Appl. Ent, 2 (1914), Ser. A, No. 7, pp. 483, 

 484)- — The author discusses the ravages of the forleule or pine moth in the 

 pine woods of Woleschna, in Bohemia. 



Combating Euxoa segetum, Enikiev (Zeml. Ohaz., No. 31 (1914), PP- 1026, 

 1027; abs. in Rev. Appl. Ent., 2 (1914), Ser. A, No. 12, p. 655).— This cutworm 

 was the source of great injury to winter-sown crops in the district of Boi'o- 

 vitchee in the Government of Novgorod in 1913. 



The morphology and biology of Carpocapsa ponionella and C. funebrana 

 (Trudy Bessarabsk. Obshch. Estest. i Liubit. Estest., 3 (1911-12), pp. 129-134, 

 pi. 1). — It is shown that the larvae of these pests may be distinguished by their 

 structure, color, and size. See also a previous note (E. S. R., 33, p. 155). 



Descriptions of new North American Microlepidoptera, A. Busck (Proc. 

 Ent. Soc. Wash., 17 (1915), No. 2, pp. 79-94) .—Among the species described that 

 are of economic importance are the following: Memythrus perlucida reared 

 from Populus trichocapa; Psacaphora cambiella reared from the cambium of 

 Salix at Evaro, Mont.; Recurvaria alnifructeUa feeding on the catkins of 

 alder and hazel at Falls Church, Va. ; Dichomeris vacciniella from cranberry at 

 Pemberton, N. J. ; Sparganothis albicaudana reared from leaf tying larvse on 

 maple at Notch, Pa.; Tortrix (Cacwcia) lambertiana on Pinus lambertiana at 

 Oakland, Oreg. ; Marmara pomonella reared from larva mining just under the 

 skin of apple at Corvallis, Oreg.; M. serotinella reared from Prunus serotina 

 at Falls Church, Va. ; Argyrcsthia castanecUa reared from the bark of chest- 

 nuts infested with Sesia casianew at Falls Church, Va. ; A. francisceUa from 

 tips of cypress at San Francisco ; Zelleria haimbachi reared from short needle 

 pine at Wenonah, N. J. ; Bucculatrix ilecella reared from Ilex sp., at Victoria, 

 Tex. ; and Prodoxus barberella from Agave palmeri at Ray, Ariz.
