St. John River, | mile wide. Pegomyia fusciceps was unusually des- 

 tructive in Ontario. Of insects affecting fruit crops, more than one 

 species of bud-moth, Eucosma, occurs in Nova Scotia, and the spray- 

 usually recommended for them is not effective ; a larger species, 

 Olethreutes frigidana, Pack., has proved injurious. The first occur- 

 rence of Rhagoletis pomonella was observed at Smith's Cove, N.S., 

 but it appears to be localised and the infestation in the affected orchard 

 was light. Cocoons of Nematus erichsonii, parasitised by Mesoleius 

 tenthredinis, were colonised in Manitoba in May 1912. The following 

 bark-beetles w^ere noted in Manitoba : Dendroctonus murrayanae, 

 Hopk., D. simplex, Lee, Ips perturhatus, Eichh., /. caelatus, Eichh., 

 Polygraphns rufipennis, Kirby, Trypodendron retusum, Lee, and T. 

 Uneatum, Ratz., also Pissodes, and Agrilus anxius [see this Review, 

 Ser. A, i, pp. 406-407.] Observations on the habits and life- 

 histories of the following were made : Dryocoetes eichhoffi, Hopk., on 

 birch, Dendroctonus and Dryocoetes in white spruce, Polygraphus 

 rufipennis, in white and black spruce, Ips balsameus, on balsam, 

 Monohammus scutellatus, etc. Tortrix fumiferana is reported to be 

 spreading eastward. Chermes similis, Gillette, C. abietis, Choi., 

 C. pinicorticiis, Fitch, C. strobilobiiis, Kalt., are noted, also Coleo- 

 phora lariceUa. Gossyparia spuria, Mod., is proving injurious to elms- 

 in Ottawa. Among other forest and shade tree pests, the following 

 were the most abundant : the beetle, Galerucella decora, on willow and 

 poplar, the moth, Podosesia syringae, Harris, on lilac, Cyllene robiniae, 

 Forst., on acacias, and the Longicorn, Elaphidion viUosuni, on oaks.

This paper deals with Lymantria dispar and is the first comprehensive 

 study of this pest in the Russian language. The various stages are 

 described, and the distribution of the very young larvae by wind, 

 which is facilitated by their very long hairs, is discussed at great length. 

 Control of this pest should be directed principally against the eggs and 

 must be made compulsory on all owners of estates, etc., as is the case 

 in Connecticut, U.S.A. The caterpillars of the first and second stages 

 preferred the foliage of apples, pears and apricots. They less frequently 

 attacked qiiinces, cherries and dogwood, and refused willow, pine and 

 cypress. 



The last chapter deals with L. dispar as a pest of forests, and the 

 entomological and biological researches of various American authors 

 are reviewed, the necessity for similar researches in Russia being 

 urged. An index of the titles of 19 publications on L. dispar, of which 

 10 are in Russian, is appended.
