{Bacillus amylovonts) in New Zealand, the importation into Australia 

 is prohibited of all plants and parts of plants, including fruit, excepting 

 agricultural seeds and grass seeds, from that Dominion. The second 

 proclamation modifies this into a prohibition against any apple, pear, 

 cherry, apricot, plum, quince or hawthorn tree, or any part thereof, 

 including fruit, grown in any country where B. amyJovorus exists. 



Pierce (VV. D.). Lectures in Applied Entomology : Vol 1. The General 

 Subject of Applied Economic Entomology — Denver, Colorado, 

 The Mineral, IMetal and By-Products Company, 1920-21, 220 pp. 

 multigraph. 



This is the first volume of a course of lectures on Applied Entomology. 

 The course is not designed to deal with injurious and beneficial insects in 

 the manner of an ordinary text-book, but rather with methods and 

 principles. The average entomologist has, owing to the vastness of 

 the science, been forced to specialise on only a limited part of economic 

 entomology, and so requires a concise summary of the field before him, 

 in order that he may render the best service. 



The first volume of the course comprises ten lectures on such aspects 

 of the subject as the first principles of economic entomology, the 

 qualifications necessary for, and the different branches of, the science, 

 and its relation to organised agriculture and other forms of industry. 



PisAR (C. J.). Use of Insecticides and Fungicides in South Africa. — 



Commerce Repts., Washington. D.C., no. 241, 13th October 1920, 

 pp. 199-202. [Received 18th March 1921.] 



Statistics are given of the importation into the Union of South Africa 

 during 1919 of sodium arsenite and other insecticides, and of the area 

 under fruit and vegetables. A list is given of the more usual insect 

 pests of fruit trees in South x\frica, with their food-plants. The 

 remedies used for each pest are described, and the regulations govern- 

 ing the sale of insecticides in the Province of the Cape of Good Hope 

 are quoted. The terms lead arsenate and sulphur, as used commer- 

 cially, are defined, with the regulations for the sale of tobacco extract 

 and cyanides. 



TicE (C). The Potato in British Columbia.— i5.r. Depf. Agric, 

 Victoria, Bull. 86, 1921, 75 pp., 78 figs. 



In the portion of this bulletin devoted to insect pests of the potato, 

 it is stated that the Colorado potato beetle [Leptinotarsa decemlineata], 

 which is established in Idaho and Washington, crossed the boundary 

 into British Columbia in 1919, but was noticed in time and apparently 

 completely exterminated. It would mean a considerable increase of 

 expense, especially to potato-growers in the Dry Belt, where spraying 

 is not at present necessary, if this pest should become generally distri- 

 buted over the Province ; and any suspected insects should be sent 

 at once to the Department of Agriculture for examination. To help 

 identification a brief description of the various stages is given. 



Blister-beetles [Macrohasis iinicolorP] do some damage to potato- 

 foliage, and they can be destroyed with arsenical sprays, but as the 

 larvae feed on locust eggs, they are probably beneficial on the whole. 



Wireworms are more or less prevalent e\'erywhere, particularly in 

 land that has previously been meadow, and in moist situations..
