139, pp. 12, ph. .'?, Jlf/.'i. .?). — The apple-tree tent caterpillar was unusually abundant 

 in Connecticut in 1902. Its common food supply is the wild cherry, but during the 

 year it was noted on a considerable variety of trees. The author gives a description 

 of the insect in its various stages, and notes on its habits, life history, and natural 

 enemies. It is recommended that egg masses be destroyed in winter. The twigs on 

 which the eggs are fastened may be readily detected and clipped off by means of a 

 tree pruner with a long handle. A special wire brush has been devised for removing 

 the nests from infested trees. Trees should be sprayed about the time the leavts 

 appear, with a solution containing 3 1V)S. arsenate of lead f)r ^ lb. of Paris green to 50 

 gal. of water. The author does not recommend the burning of the nests on the tree. 



Some destructive caterpillars, E. D. Sanderson {Delairare Sta. Bui. 56, pp. 

 28, figx. 14). — In this bulletin the author presents notes on the appearance, habits, 

 life history, and means of combating fall webworm, white-marked tussock moth, 

 and apple-tree tent caterpillar. The usual methods for controlling these insects are 

 recommended. They include banding the trees, collecting the eggs, burning the 

 nests of caterpillars, and spraying. 



Coccidae of Japan, 8. I. Kttwana {Contrib. Biol. Hopkins Seaside Lob. Leland 

 Stanford Jr. Univ., 1902, No. 27; reprinted from Proc. California Acad. Sei., 8. ser., 

 ZooL, 3 [1902), No. 2, pp. 39-98, pis. 7). — The author presents an account of the life 

 history, habits, and distribution of a large number of Coccida; from Japan, and a list 

 of species recorded from Japan but not discussed in detail is also given. 



Insecticide experiments for the San Jose scale [Illinois Sta. Circ. 53, pp. 2). — 

 This circular contains a brief abstract of Bulletins 71 and 72 of the station (E. S. E. 

 14, p. 270). 



The rose scale (Diaspis rosse) , J. B. Smith [Neio Jersey Stas. Bui. 159, pp. 14, 

 figs. 6). — This insect has been noted as injurious for a number of years. It causes 

 most damage to the rose, blackberry, and raspberry. The winter may be passed in 

 any stage. Twigs which were examined in December, in 1901, contained all stages 

 except the active a<hilt male. The larva? are usually hatched by the beginning of 

 March, and by the following November all stages are found on infested twigs. Breed- 

 ing is apparently almost continuous after the beginning of the season, but there 

 are probably not more than 3 broods per year. Detailed notes are given on the 

 mouth parts of the insect, and on the manner in which it feeds. The insect seldom 

 kills growing blackberry or raspberry canes, but its injuries may be serious on badly 

 infested rose bushes. Infested shoots of blackberries or raspberries should be cut 

 off as soon as the fruit is harvested. If infestation becomes serious during the sum- 

 mer, the plants may be sprayed with a weak solution of whale-oil soap or a 10 per 

 cent mechanical mixture of kerosene or crude oil with water. Nearly all of the 

 scales w-ere killed by an application of 1 lb. whale-oil soap in 1 gal. of water, and no 

 injury was caused to the canes by these applications. Similar methods of treatment, 

 with slight variations, may be adopted in case of infested rose bushes. It is suggested 

 that lime, salt, and sulphur mixture may prove very effective in controlling this 

 insect. 



Lime, sulphur, and salt wash for scale insects, C. P. Lounsbukv (Agr. Jour. 

 Cape Good Hope, 20 [1902), No. 13, pp. 768-776). — Brief notes are given on the origin 

 and history of the use of this mixture in various English colonies and in the United 

 States. It is stated that the lime, sulphur, and salt wash was first introduced into 

 Cape Colony by P. J. Cillie in 1893, and has since been used with pronounced success 

 in treating fruit trees and other jilants for scale insects as well as fungus diseases. A 

 number of experiments were conducted with this insecticide for the purpose of deter- 

 mining the necessary ingredients and their proper proportions in the preparation of 

 the wash. It was found that the compounds of lime and sulphur are the effective 

 agents in the wash. Spraying experiments with this insecticide indicated that, as 

 noted by other investigators, the action of the wash may be extremely slow. Soon
