The first section of this small volume deals in a simple manner 

 with the morphology, biology and classification of insects. The 

 chief families of economic importance in France are listed, in each 

 case with notes on their habits. Formulae for insecticides, etc. are 

 given, with a list of French entomological stations where the public 

 can obtain advice. The main section is divided according to the 

 character of the plants concerned, the pests involved being described 

 in paragraphs, at the head of each of which the synonymy and French 

 popular names are given. The practical value of the book is enhanced 

 by an index covering all the scientific and popular names.

Carob Tree Destruction by the Great Capricorn Beetle. — Cyprus Agric. 

 J I., Nicosia, xvii, pt. 2, April 1922, p. 28. 



The Cerambycid, Ceramhyx heros. Scop., does considerable damage 

 to carob and walnut trees in Cyprus. Eggs are laid beneath the 

 bark in July, or in the crevices caused by faulty pruning. The grubs 

 penetrate the wood and gradually work their way to the interior, 

 where they feed for three to four years and then pupate in the spring. 

 The remedy is systematic and careful pruning, so that no rough edges 

 or cracks are left to harbour eggs. The trunks and main branches 

 should be limewashed, and pieces of cotton wool soaked in benzine 

 or turpentine should be placed in the holes and crevices and covered 

 with mud in order to kill the insects by fumigation.
