Observations on a gall aphid (Aphis atriplicis), P. Hayhurst (Ann. Ent. 

 Soc. Amer.. 2 {1909), No. 2, pp. 88-99, pi. 1). — Biological observations with de- 

 scriptions of the stages observed. This aphid colonizes the upper surface of the 

 leaves of Chenopodium album and Atriplcx jxitula. Several species of parasites 

 were reared. A bibliography is appended to the account. 



[Recent publications on Chermes], O. Ntjsslin (Zool. ZentbL, 16 (,1909), 

 No. 21-22, pp. 649-673).— A critical review of the literature. 



Webber's brown fungus of the citrus white fly (.ffigerita webberi n. sp.), 

 H. S. Fawcett (Science, n. ser., 31 (1910), No. 806, pp. 912, 9/3).— This fungus, 

 a parasite of the citrus white fly, previously described by Webber (E. S. R., 9, p. 

 658) under the name of brown fungus, is designated by the author as /Egerita 

 icebberi. 



The scale insects of citrus trees, C. W. Howard (Transvaal Dept. Agr., 

 Farmers' Bui. 15, pp. 20, figs. 7). — The red scale (Chrysomphalus aurantii) is 

 stated to be the most destructive coccid that affects citrus fruits in the Trans- 

 vaal. The Florida red scale is found in the Transvaal mostly in the low veld 

 along the eastern borders. In the dryer parts it is often found upon palms in 

 greenhouses and in Natal seems to prefer the coastal belt. The purple scale, 

 often associated with the Florida red scale, is confined to the same warm humid 

 areas in South Africa. Glover's scale is not very common, being found in the 

 Transvaal only at Warmbaths. The circular white scale (Aspidiotus hederce) 

 l^as only once been reported as a pest of citrus trees in the Transvaal, but in 

 Natal it frequently attacks rough lemons. The soft scale is said to be a serious 

 pest of citrus trees in the Transvaal, although highly parasitized by a small 

 chalcidid. The black scale has been reported but once and the cottony cushion 

 scale is not considered a serious pest. 



Scale insects affecting coffee estates, R. D. Anstead (Planters' Chron., 5 

 (1910), Nos. 19, pp. 222-221,; 20, pp. 23J,-236; 21, pp. 247-249).— The coccids 

 mentioned as usually found attacking coffee and its shade trees in southern 

 India are the so-called green bug (Lecanium viride), brown bug (L. hemi- 

 splnrricitm), red cedar scale (L. imbricans), silver oak scale (L. formicarii), 

 black bug (L. nigrum), green mealy scale ( Pulvinaria psidii), and Dactilopius 

 citri. The natural enemies of and i-emedial measures for these pests are briefly 

 considered. 



Catalogue of the Lepidoptera Phalaenae in the British Museum, G. F. 

 Hampson (London, 1909, vol. 8, pp. XIV+58S+2S, pis. 14, figs. 162; 1910, vol. 9, 

 pp. XV-{-552+28, pis. 11, figs. 247). — The Acronyctinae are continued in these 

 volumes. A key to the genera, which appeared in volume 7 (E. S. R., 21, p. 760), 

 is reprinted with some additions and corrections in both of the present volumes. 



In volume 8, 720 species are listed with descriptions and in volume 9, 676. 

 Many of the species are illustrated in color. 



A natural history of the British Lepidoptera, their world-wide variation, 

 and geographical distribution, J. W. Tutt (London and Berlin, 1905, vol. 8, 

 pp. III+479, pis. 20; 1907-8, vol. 9, pp. X+494, pls. 28; 1908-9, vol. 10, pp. 

 VII 1+4 10, pis. 53). — These volumes, devoted to British butterflies, are a con- 

 tinuation of the work previously noted (E. S. R., 18, p. 1144) of which volumes 

 6 and 7 are still unpublished. 



In volume 8 the first part is devoted to general observations and the second 

 part to 10 species of butterflies. In volume 9 the estivation, hibernation, and 

 gregarious and family habits of butterfly larvfe are considered, followed by 

 accounts of 7 species. Part 1 of volume 10 takes up the family habits of butter- 

 fly larvse following which 5 species are discussed. The species considered are 

 traced through their extreme range of variation and geographical distribution 

 and their life history worked out in detail.
