Bull 476; Dec. 26, 1911).— Of late years the killing out of Pine trees 

 in the Southern Atlantic and Gulf States, principally by insect pests, 

 has attracted general attention. 



Descriptions of the various insects and best methods for combating 

 these pests are included in this paper. — A. D. W. 



Pine Trees, Weevil Destructive to. By W. W. Frogatt {Agr. 



Gaz. N.S.W. vol. xxiii., pt. i., pp. 55-56; 1 plate). — The weevil 

 [Aesiotes leucurus) deposits its eggs on the bark of pine trees; the grubs 

 feed between it and the sap wood, doing great damage. The weevil, 

 cocoon, pupa, and larva are depicted in the plate. — S. E. W. 



Pine, Western Yellow, in Arizona and New Mexico. By 



Theodore S. Woolsey, jun. {U.S.A. Dep. Agr., Forest Service, 

 Bull. 101 ; Nov. 24, 1911). — By far the greater part of the lumber 

 exported from Arizona is that of the Western Yellow Pine (Pinus 

 yonderosa), a tree of which there are casual good specimens to be found 

 throughout the British Isles, where, however, it does not thrive 

 sufficiently well to be worthy of using for afforesting purposes. 

 Although the tree does not reach the size attained on the Pacific Coast, 

 yet it is well suited for the arid soils of Arizona, and produces large 

 quantities of valuable timber. — A. D. W. 



Plantagro, New Species of the Sections Cleiosantha and 

 Novorbis. By E. Pilger (Not. Kowig. Boi. Berlin, vol. v. No. 49, 

 pp. 259-263 ; June 1912). — Ten new species of Plantago are described 

 -—viz. P. accrescens from the Argentine, P. alismatifolia from Mexico, 

 P. suhnuda from California, P. Jiypolasia from Uruguay, P. Kurtzii 

 from the Argentine, P. nigritella from the Argentine, P. Pflanzii from 

 Bolivia, P. refracta from Patagonia, P. RojasU from Paraguay, 

 P. Stuckeriii from the Argentine, and P. Stuckertii sub.-sp. catamar- 

 censis from the Argentine. — R. B. 



Plant Diseases in Connecticut. G. P. Clinton, Sc.D. (U.S.A. 



Exp. Stn., Conn., Rep., 1909-1910). — This report includes notes on 

 plant diseases in Connecticut, spraying experiments on potatos in dry 

 seasons, and a description of experiments in which the author claims 

 to have found oospores of Phytophthora infestans when grown in 

 artificial media, and also to have obtained hybrids of P. infestans with 

 P. cactorum, and also with P. phaseoli. 



He was unable, however, to obtain oospores of Phytophthora 

 infestans when grown on culture media of potato juice agar.

Poisonous Sumachs (Oeslr. Gart. Zeit., vol. vii., pt. i., pp. 15- 

 19). — Examples are given of the poisonous action of Rhus Toxicoden- 

 dron, R. vernicifera, and R. atrum. When a rash is produced by 

 coming in contact with these shrubs, apply a solution of lead acetate 

 or potassium carbonate, tincture of Sanguinariw canadensis, or Grindelia 

 rohusta to the parts affected -S, W.
