REVIEWS. 95 



The present volume is complete in itself, but it is intended 

 to publish three or four others, containing the remaining or- 

 ders. Thus for a trifling expense, at a few periods, a complete 

 abstract of a twenty-guinea work will be in the hands of the 

 reader. 



Art, II. — A Treatise ou the Insects injurious to Gardeners^ Foresters, and 

 Farmers. By Vincent Kollar, Curator of the Royal Cabinet of Na- 

 tural History at Vienna, and Member of many learned Societies. Trans- 

 lated from the German, and illustrated by Enp^ravings. By J. and M. 

 Loudon : with Notes, by J. O. Westwood, F.L.S., &c. London : W. 

 Smith. 1840. Sm. 8vo. pp. 377. 



This work is of a totally different character from that of Mr. 

 Stephens above described. Impressed with the conviction 

 that the most likely means of attaining a knowledge of the 

 most effectual remedies against the attacks of the various 

 species of obnoxious insects, are to be sought for in a know- 

 ledge of their respective habits, M. Kollar and his associates. 

 Baron Kreigelstein and Canon Schmidberger, have devoted 

 their attention to the economy of the different species, and 

 the result has been a volume on the history and " Private 

 Lives " of about one hundred and twenty-five of the insects 

 most obnoxious to vegetation. And we have now to thank 

 the Misses Loudon for their careful translation of the work 

 from the German, and for the numerous wood- cuts with 

 which they have illustrated the text, whereby a better notion 

 will be obtained of the species. 



To enable the farmer and arboriculturist, — w^ho, of course, 

 are not always adepts in scientific classification, — to find more 

 easily the insects particularly interesting to each, the families 

 and species are not given in any systematic arrangement, but 

 according to the branch of culture to which they prove most 

 injurious. The insects troublesome to sheep and cattle are 

 also given, and the work contains a popularly written sketch 

 of the principles of entomological science. The translation 

 being more especially intended for the agriculturist and gar- 

 dener, those chapters in the original work which treated upon 

 body insects and house insects are omitted in the translation. 



The following is a sketch of the sections into which the 

 translation is divided. 



L Insects which do not live upon the body, but are troublesome from their 

 attacks upon man. 

 Insects which live on domestic animals. 



Insects not parasitical, but which sometimes attack domestic animals. 

 Insects which injure bees.
