eimiLsiun, wluile-oil Hoap, Montgomery's insecticide, ((jIku-co decoction, sulpliur dust, 

 and hydrocyanic-acid gas. The most favorable time for spraying is during the 

 winter period; at least 2 thorough applications should ])e made. Fumigatif)n with 

 hydrocyanic-acid gas proved effective, but is not generally recommended. Hesin 

 wash is considered to be a very satisfactory sjjray and potash whah'-<;il soap ma}' 

 also be nse(l with good success and with little injui-y t<j the trees. 



The white fly, II. A. (iossakd {Florida Sla. FannerH' Ivt^t. Bui. 1, pp. 2U-50). — 

 The white 11 y is <lescril)ed in its various stages and notes are given on its habits and 

 lifi' history. A number of remedies have been tried in combating this insect, and 

 good results are reported from the use of resin wash and other similar insecticides. 

 A parasitic fungus is believed to help appreciably in the destruction of this insect. 



Fiddler beetle {Jour. Jamaica Agr. Soc, 7 {1903), No. 7, pp. ^75-,?77).— The roots 

 of orange trees are said to be greatly injured by a beetle which was identified as 

 Exophi]ialmu!< vittatus. The beetle is most injurious in its larval condition. The 

 adult beetles may be jarred from the orange trees in the early morning and captured. 



An enemy of olive grafts, Trabut {Bid. Agr. Ahjhie et Tunisie, 9 {1903), No. 18, 

 pp. 308, 309, _fi(j. 1). — Consideral)le injury to the grafts of olives is reported as due to 

 the attacks of Otiorhynchus crebricollw. The young grafts niay be protected by 

 spraying with arsenical insecticides. 



Lecanium oleae, Trabut {Bui. Agr. Algerie et Tunisie, 9 {1903), No. lJ,pp. 258, 

 269). — This insect is considered one of the worst pests of the olive. Since certain 

 of the enemies of the olive scale live on fig trees, it is recommended that the latter 

 trees be planted in the vicinity of olive groves. 



A new destructive scale insect, Tkabut {Bui. Agr. Algerie et Tuninie, 9 {1903), 

 No. 13, p>p. 289, 290, fig. 1). — Notes are given on (Jeroplastea sinensis, which is consid- 

 ered one of the most important enemies of the orange in Algeria. 



The San Jose scale: its native home and natural enemy, C. L. Maklatt 

 {V. K Dept. Agr. Yearbook 1902, pp. 155-174, pis. 6, figs. 3). — A discussion of the 

 history, distribution, natural enemies, and home of the 8an Jose scale. As a result 

 of the author's travels in the Orient it is believed that China is the original habitat of 

 this insect. Considerable assistance may reasonably be expected from Chilocorus 

 mnilis in the destruction of the scale. This ladybird was introduced from China and 

 has been distributed in a number of localities in the United States. 



A. catalogue of the Coccidae of the world, Maria E. Fernald {Massachusetts 

 Sta. Bui. 88, pp. 3H0). — The number (^f species of Coccidse recognized in this bulletin 

 is al)Out 1,500. The preferred specific name is given in each case, followed by full 

 bibliograiihic references and synonyms. A detailed index contains the names of 

 subfamilies, genera, subgenera, species, and subspecies. This index enables the 

 entomologist to make rapid references to the names and synonymy to the various 

 species as contained in the text of the bulletin. 



Some w^ood-boring beetles and their habits, W. W. Froi^gatt {Agr. Gaz. New 

 South Wales, 14 {1903), No. '5, pp. 414-417, 1)1. 1). — Descrii)tive, biological, and 

 economic notes on Bostrgchus cglindricus, Nylehorus solidas, Lyctus hrunneus, and 

 Gracilia pygnuea. Xyleborus was reported as causing considerable injury to apple 

 and peach trees. The apple trees were most affected. In some cases limbs 1 in. in 

 diameter were so ])adly eaten that they readily broke off. 



Some of the principal insect enemies of coniferous forests in the United 

 States, A. D. Hopkins ( U. S. Dept. Agr. Yearbook 1902, pp. 265-282, jils. 2, figs. 10).— 

 An account is presented of the habits, life history, and means of combating Dendroc- 

 tonus piceaperda, D. frontalis, D. ponderosie, and other injurious species of this genus. 

 The autlior briefly indicates the remedies which may be employed in checking the 

 spread of these insects. 



The narcissus or daffodil fly, W. Wilks {Jour. Roy. Ilort. Soc. \_London'], 27 

 (1902) , No. l,pp. 181-185, fig. 1). — A study was made of the life habits and history of
