general throughout Missouri and eastern Kansas. It accomplishes its injury in the 

 spring by the larvae eating into both the leaf and llower buds while they are 

 unfolding, and ultimately causing them to drop at about the time, or shortly after, 

 the flowers (petals) fall." 



The following - directions are given for combating the insect: 



"Although this pest is a difficult one to comhat owing to its habits of feeding 

 within the young developing and unopened leaves, we were successful in holding it 

 in check and in preventing the greater percentage of the fruit buds from being 

 destroyed by early, thorough, and frequent applications of Paris green. The mix- 

 ture to be used for this insect is: One pound of pure Paris green, 3 lbs. of fresh lime, 

 and 150 gal. of water. The mixture must be constantly stirred while spraying, and 

 the work done thoroughly on both sides of the tree. The first application is to be 

 made as soon as the buds open and the green leaves first appear sufficiently to give, 

 the tree a green tinge, the second application about 5 days later, and the third at 

 the time the first flower buds are about to open." 



A new breeding cage used in the study of the fringed-wing apple- 

 bud moth is described and illustrated. 



The peach-twig borer, C. L. Marlatt (U. 8. Dept. Agr., Division 

 of Entomology Bui. 10, n. ser., pp. 7-20, figs. 5). — This article discusses 

 the origin and distribution of the peach-twig borer (Anarsia lineatella), 

 its characteristics, life history, and habits, natural parasites, remedies 

 to be used against it, etc. It is pointed out that the strawberry-crown 

 miner, which has been supposed to be identical with the peach-twig 

 borer, is a distinct insect. 



As a remedy the author recommends winter treatment with kerosene 

 emulsion, resin wash, or some similar oily preparation which will pene- 

 trate the burrows and kill the young larvae. The itse of arsenical sprays 

 in spring and fall is noted, but the operator is cautioned to use only 

 weak sprays — 1 lb. of the poison with an equal amount of lime in 200 

 gal. of water — to prevent scalding the very sensitive peach foliage. 

 Removal and burning of withering infested tips of the trees in the 

 spring as soon as injury is noted is thought to be often impracticable 

 or even of doubtful utility. 



A bibliography of the principal writings on the peach-twig borer is 

 given. 



The quince curculio, M. Y. Slingerland {New York Cornell Sta. 

 Bui. 148, pp. (195-715, Jigs. 10). — The quince curculio (Conotrachelus 

 cratevgi) is considered the most serious enemy of the quince in New 

 York. "During the past few years this quince curculio has caused a 

 greater monetary loss to some of the larger quince growers in western 

 New York than all the other insect foes and fungus diseases of the 

 quince combined.'' The history, distribution, food, life history, habits, 

 appearance, and natural enemies of the insect are given. It breeds in 

 the wild haws and often attacks pears, but has a special liking for 

 quinces. It is not known to breed in apples. Picking oft' and destroy- 

 ing infested fruit is impracticable, since it is often difficult without 

 mutilating the fruit to determine whether it is infested. "The experi- 

 ence of some of our largest and most successful quince growers who
