N. macropliyriaXN. collossea, is characterized for the first time under the name 

 Pseudococcus nicotianm. 



The oyster-shell scale (Lepidosaphes ulmi), F. Sherman, Jb. {Bui. N. C, 

 Dept. Agr., S4 (1913), No. 6, pp. 23, figs. G). — A somewhat detailed account of 

 this pest with remedial measures therefor. 



" It is very prevalent throughout all the mountainous section of the State, 

 and through the upper Piedmont or ' foothill ' region, and is also recorded in 

 several scattered localities as far eastward as the counties of Meclilenburg, 

 Stanly, Rowan, Davidson, Chatham, Wake, and Granville. It is believed that 

 on an average it is more severe in the more eastern localities than in the moun- 

 tainous parts of the State." 



[Parasites of the San Jose scale in Pennsylvania], H. A. Surface {Amer. 

 Agr., 92 (1913), No. 16, p. S25, figs. 2; New England Homestead, 67 {1912), 

 No. 16, p. 305, fig. 1; Rural New Yorker, 72 (1913), No. 4226, p. 1151, figs. 3).— 

 The chalcidid Aphelinus fuscipennis, an undetermined species of Anaphes and 

 several other proctotrupids new to science are reported to parasitize highly the 

 San Jose scale in the southeastern part of Pennsylvania. It is stated that in 

 a large number of orchards where the fruit was rendered unfit for sale 2 years 

 ago not a living San Jose scale nor specimen of specked fruit can be found at 

 the present time. 



[Parasites of the San Jose scale], L. O. Howard (Tribune Farmer [N. Y.], 

 IS (1913), No. 629, p. 3). — Identification of the parasites mentioned by Sur- 

 face (see above) as playing an important part in the destruction of the San 

 Jose scale in Pennsylvania has been made by the author, who finds them to 

 be Aphelinus fuscipermis, ProspaUella perniciosi, Signiphora nigrata, and 

 Anagrus spiritus. 



Inquiry into the insecticidal action of some mineral and other com- 

 pounds on caterpillars, H. Maxwell-Lefroy and R. S. Finlow (Mem. Dept. 

 Agr. India, Ent. Ser., 4 (1913), No. 5, pp. 269-327; abs. in Rev. Appl. Ent., 1 

 (1913), Ser. A, No. 8, pp. 285, 286).— This paper reports in detail the results 

 obtained in a large series of tests of poisons on insects. The experiments 

 were carried on in an attempt to find substitutes for arsenicals and their 

 practical outcome resulted in the selection of lead chromate as a standard 

 stomach jwison to replace arsenical poisons, and the selection of certain avail- 

 able dry paints which are recommended for application as deterrents on young 

 crops. See also a previous note (E. S. R., 24, p. 63). 



The wattle bagworm (Chalioides junodi), C. Fuller (Agr. Jour. Union So. 

 Africa, 5 (1913), No. 6, pp. 838-855, figs. 6; 6 (1913), Nos. 1, pp. 19-33; 2, pp. 

 198-215, figs. 40). — The insect here discussed, a native of South Africa, is 

 widespread and not uncommon in the Provinces of Cape, Transvaal, and Natal. 

 In this paper the author presents a discussion of the wattle industry, the 

 physical and climatic features of Natal, the bag^vorm zone and injury, the 

 monetary loss in relation to control measures, gross infestations, the life cycle, 

 emergence and dispersal of the young, and the making of the bag. 



Two Microlepidoptera injurious to chestnut, A. BuscK (Proc. Ent. Soc. 

 Wash., 15 (1913), No. 3, pp. 102-104, fig. 1). — The two species here described 

 as new are Sesia custanew, reared from the trunks of chestnuts; and Ectoedemia 

 castanew, reared from small galls on young twigs of the chestnut. 



A microlepidopterous enemy of the vine (Caccecia costana), F. Picabd 

 (Prog. Agr. et Vit. (Ed. I'Est-Centre), 34 (1913), No. 22, pp. 678-684, Pl- !)■— 

 A brief discussion of t}iis pest, its habits and injury, natural enemies, and 

 means of combating it. 



The caterpillars of tVe autumn generation emerge from hibernation in the 

 early spring immediately after the buds swell, at which time they have attained
