are fairly satisfactory. A copy is given of a set of regulations adopted by the pro- 

 vincial council for the destruction of field mice. 



A preliminary list of the insects of economic importance recorded from the 

 Hawaiian Islands, J. G. Kikkaldy (Hawaiian Forester and Agr., 1 {1904), Nos. 6, 

 pp. 152-159; 7, pp. 183-189; 8, pp. 205-210).— -This list is prepared for the purpose 

 of furnishing information regarding the number and distribution of injurious insects 

 in the Hawaiian Islands. Lists are presented of Hemiptera, Orthoptera, Lepidoptera, 

 and Hymenoptera of the islands with bibliographical references. 



Annual report of the inspector of cocoanut trees, 1902, L. C. Brown (Agr. 

 Bui. Straits ami Federated Malay States, 2 (1903), No. 5, pp. 161-163).— The author 

 made a study of a cocoanut grove in the Federated .Malay States and found that 

 many trees were cut down and left to lie in a half-rotten condition on the ground. 

 Such trunks serve as breeding places for borers and other injurious insects. With 

 proper precautions and the application of clean cultural methods the losses from 

 insect pests can be gradually reduced. 



Report of the government entomologist, E. E. (Jreen (Roy. But. Gard. Ceylon 

 Adminstr. Rpts. 1903, pt. 4, pp. 10-18). — Notes are given on the habits and life history 

 of a number of injurious insects, in particular the more important pests of tea, coffee, 

 cacao, rubber, timber, etc. 



Further notes on pests attacking cotton in the West Indies, H. A. Ballou 

 ( West Indian Bui. 4 (1904), No. 4, pp- 326-354)-— Detailed notes are given on the 

 habits, life history, natural enemies, and means of combating the cotton worm, cotton 

 stainer, red maggot, Eriophyes gossypii, and various fungus diseases of cotton. As a 

 result of the study of insect and fungus diseases of cotton, recommendations are 

 made for the culture of cotton according to methods which will assist in preventing 

 the damage from these pests. 



The sting in the apple. — The work of the plum curculio in the apple, J. M. 

 Stedman (MissouriSta. Bat. 64, pp. 24, figs. 10). — During the summer of 1904 a serious 

 attack of plum curculio on apples was observed throughout the State of Missouri. 

 Nearly all of the injuries were due to the plum curculio, while a small percentage of 

 damage was caused by the apple curculio. 



The plum curculio attacked the apples about the middle of May and became most 

 numerous in June. The females make punctures for the purpose of obtaining food 

 and for the purpose of oviposition. About 5 times as many feeding punctures were 

 observed as egg punctures. When the adult beetles appear later in the season they 

 have the habit of eating the apple pulp, making holes of considerable size. A num- 

 ber of punctures may be made in the single fruit and these punctures may serve as 

 points of entrance for fungus diseases. The plum curculio does not readily breed in 

 the apples. Apparently not more than 15 per cent of the eggs which are deposited 

 ever hatch and not more than 2 per cent develop to the adult condition. 



Detailed notes are given on the life history and habits of this pest especially in 

 connection with apple orchards. According to the author's experience, the pests 

 may be successfully controlled by spraying with arsenate of lead once or twice before 

 the blossoms open and 3 or 4 times after the blossoms have fallen at intervals of 10 

 days. All windfalls should be destroyed at intervals of about 7 days and the 

 orchard should be plowed and receive shallow cultivation in the middle of July and 

 again in August. 



Observations on the habits of the asparagus fly, P. Lesxe (Rev. Hort. [Paris'], 

 76 (1904), No. 14, pp. 332, 333, fig. 1). — The asparagus fly (Platyparea pceciloptera) 

 has long been known as an enemy of asparagus. The author made a study of the 

 habits and life history of this pest. A great variation was observed in the time of 

 the development of the larva? from the egg stage. The deposition of eggs in the tis- 

 sues about the tip of growing stems of asparagus appears to indicate the possibility
