ENTOMOLOGY. 873 



Tlie remedies recommended for this species consist in paintino; abrasions in tlie liark, 

 with a sHght addition of Paris green; scraping loose bits of l)ark from the trunk and 

 applying a wash of whale-oil soap, caustic soft soap, or other sul)stances in winter; 

 in the summer tlie borers may be cut out. 



V>v\e( notes are given on the periodical cicada with special reference to the brood 

 which will ai)pear (hiring the present season. It is urged that orchards should not 

 be ]truned too closely, and that where possil)le budding and grafting should be post- 

 poned until after the appearance of the cicadas. 



The cherry fly, K. S.\.i6 {Prometheus, 12 {1901), No. 614, PP- 6G3-GG8, fi<j. 1).— 

 Detailed notes are given on the habits and life history of Spiloyrapha rerasi. In 

 breeding experiments with this insect it was found that the species lives over in the 

 impa condition until the second year, and it is ])elieved that in some cases it may 

 remain in that state until the third year. It was found impossible to secure the 

 emergence of the adult insect from the ])upa during the first year, although the tem- 

 perature and moisture conditions were made as favorable as possible. As a result of 

 the author's observations it is recommended that the soil around infested trees should 

 be removed to a depth of a few inches and covered in such a manner that the insects 

 can not escape. This soil should be left undisturbed during the summer of the sec- 

 ond year in order to make it certain that all insects contained in it are destroyed. 

 Infested cherries when detected should be thoroughly cooked or otherwise treated 

 so as to destroy the fly larv;e contained in them. 



Remedies for the cankerworm, C. M. Weed {New Hampshire Sia. Bui. 85, pp. 

 G'J-7G, fujs. 5). — The cankerworm is reported as having done an unusual amount of 

 injury in the past 2 or 3 years. Brief notes are given on the habits and life history 

 of this insect. In combating the cankerworm, banding the trees and spraying with 

 arsenicals are recommended. Good results are reported from the use of Bodlime in 

 painting trees. This substance is placed around the trunks of old trees and is 

 removed after danger from the cankerworm is past. Brief directions are given for 

 applying arsenicals for destroying the cankerworm. Mention is made of arsenate of 

 lead, Paris green, and Scheele's green in this connection. 



Currant aphides {Jour. Bd. Agr. [London], S {1901), No. 3, pp. 30G-31'2, figs. 2).— 

 Descriptive, biological, and economic notes are given on species of plant lice affecting 

 currants, including liltopalosiphnm rihis, Myzus ribis and M. cerasi. Brief mention is 

 made of the natural enemies of tliese in.sects. As a treatment for currant-jilant lice 

 it is recommended that infested bushes should be cut back and the pruned twigs be 

 destroyed. A caustic alkali wash may be applied for destroying the eggs of the plant 

 lice. Besides this wash, kerosene emulsion and a decoction of quassia, alone or in 

 combination with kerosene emulsion, are recommended. 



Thrips on cacao trees, II. Maxwell-Lefroy {West Indian Bui., 2 {1901) No. 3, 

 pp. 175-190, figs. 3). — It is reported that cacao trees in Barl)ados suffer to a 

 greater or less extent from the attack of thrij)s. The insect injured the leaves of 

 young and old trees and attacked pods in all stages. The pods turned to a deep 

 brown color as the result of injury from thrips. It is suggested that not all of the 

 damage to cacao trees which has been attributed to thrips is really due to these 

 insects. In controlling the thrips it is recommended that after the beans are removed 

 infested pods should not be allowed to remain on the ground where the young thrips 

 mature, but should be burned, or otherwise destroyed. Pods and leaves may be 

 sprayed with kero.sene emulsion, resin wash, or other similar insecticides. Other 

 native food plants of the insect in the vicinity of cacao plantations should be destroyed. 

 Formulas are given for the preparati(^n of resin wash, resin comi)()uiid, kerosene 

 emulsion, resin and whale-oil soap combined, and whale-oil soap. 



Combating the coffee borer {Rev. Agr. Rmnion, 7 {1901) No. 10, pp. 412-417).—
