In 1889 I received from the late William Brown, of Charlottetown, P. E. I., some larvæ of a small case-bearer, which he had found in large numbers upon his plum trees, and which also occurred in his pear and apple orchards. Since that time this insect has made itself well-known by its injuries in apple orchards in various localities in the Maritime Provinces, and in the Provinces of Quebec and Ontario. A beautifully illustrated and carefully prepared bulletin has been issued by Mr. M. V. Slingerland, of Cornell University Agricultural Experiment Station, in which the life history of this most interesting but very serious enemy of the fruit grower is fully described. The above illustration, kindly lent by the editor of the Canadian Horticulturist, is copied from that bulletin.

`PMR Delicious 51' is a new and improved version of the `Delicious 51' eastern type melon (Cucumis melo L.). It was developed in the Department of Plant Breeding at the Cornell University Agricultural Experiment Station in Ithaca, N.Y. It is well adapted for northeastern U.S. conditions and shows potential for good adaptation in the northwest. It is well suited for home gardeners, market gardeners, and commercial growers who want to grow an open-pollinated (OP) melon. `PMR Delicious 51' has excellent resistance to powdery mildew races 1 and 2 (Podosphaera xanthi) and resistance to fusarium wilt (Fusarium oxysporum f. sp. melonis) race 2.

In studying the larva and pupa of Steganoptycha pyricolana, Murt., some observations were made as to structure, which it seems desirable to permanently record. The life-history and habits of the species have been described in the Twelfth Report of the Delaware Agricultural Experiment Station.“This species was described by Miss M, E. Murtfeldt, in Bulletin No. 23, o. s., Div. Ent., U. S. Dept. Ag.., p. 52, as S. pyricolana, Riley MS. Concerning the identity, it was stated that ‘Professor Fernald, to whom a specimen was shown, considers it identical with Clemens's S. salicicolana, which, I believe, breeds in willow galls, but Dr. Riley pronounces it distinct, and he has types of Clemens's species.’ My specimens agree entirely with Miss Murtfeldt's description, but are distinctly different from Clemens's types in the collection of the Am. Ent. Society. Correspondence shows that the opinion credited above to Dr. Fernald is incorrect, as he never compared the specimens.

During the past decade it has become so destructive over a large area in Illinois and in a limited section of Ohio that serious study of the life history and control of the pest has been made by both the Illinois Natural History Survey and the Ohio Agricultural Experiment Station, and the present publication is issued to set forth the results of these studies.
