belonging to the family Clcridce {Thmiasimus nuhilus), which preys upon 

 the beetles. Among birds the chief enemies of this pest are various 

 kinds of woodpeckers. Two other beetles belonging to the family 

 ScolytidcB also assist in a measure in causing the death of Spruces, and 

 there are various other insects that to some extent participate in the 

 work of destruction, but only in a slight degree. Various remedies and 

 methods of prevention are discussed. The most useful appear to be 

 regulating the winter cutting, so that as many infested trees as possible 

 may be felled, and placing the logs in the water before June 1 ; and in 

 summer by removing the bark from the felled timber as soon as it is cut, and 

 girdling early in June a number of trees where logging will be carried on 

 during the following summer or winter. The girdled trees should be felled 

 and barked, or put in water before the next June. — G. S. S. 



Insect Pests in U.S.A. {Amer. Gard. xxii. pp. 730, 762, 810, 828 ; 

 26/10 1901, et seq.). — A series of articles containing the synopsis of the 

 horticultural laws, rules, and regulations of the States, Territories, &c., of 

 the United States, issued by the New York State Department of Agri- 

 culture. These have special reference to the inspection, certification, and 

 transportation of nursery stock, and in many cases seem to us to be very 

 stringent, though doubtless of great national value. — C. C. H. 



Insects. Control over. By H. Maxwell Lefroy {Jour. Imj). Dep. 

 Agr. W.I. vol. ii. No. 4, p. 318). — Suggestions of the utmost value for 

 establishing such a control over the entry of plants &c. into any country 

 as to prevent the introduction of insect pests. Some central authority, 

 it is suggested, should have power for the general welfare of (1) destroying 

 all plants &c. found to be infested with disease ; (2) of prohibiting importa- 

 tion of plants from specified places known to be suflering from diseases ; 

 (3) of inspecting nurseries and issuing or refusing certificates of plant 

 health, without which no distributing should be permitted ; (4) of 

 inspecting and of either fumigating or imposing quarantine on suspected 

 plants. It also gives most useful advice as to preventive methods and 

 remedial measures, not omitting the protection of useful birds, lizards, 

 toads, bats, &c., and suggests the introduction of certain new forms of 

 animal, bird, and insect life to the West Indies. It is a most valuable 

 and exhaustive essay, and should be studied by all who are interested in 

 reducing or excluding insect pests. — W. W.
