Natural History of Injurious Insects. 235 



Hope has been enabled to clear up the doubts attaching to 

 many of the Linnsean and Fabrician species, although some 

 still remain, and which it is to be hoped that the continental 

 entomologists will endeavour to settle, by reference to the ca- 

 binets described by Linnaeus and Fabricius, and thus over- 

 throw the frivolous arguments of Dejean, promulgated in the 

 new edition of his Catalogue. The frontispiece to his work 

 represents a splendid new species of Goliathus, and the 

 other plates are filled with structural details of the new ge- 

 nera described in the appendix. We trust that the other 

 groups of the Coleoptera will be similarly treated. 



The last work on our list contains a slight but concise 

 sketch of the distribution of the Coleopterous genera, with lists 

 of some of the more conspicuous species of beetles inhabiting 

 Germany. Such a work is more requisite in that country 

 than it would be in France, where the works of Latreille and 

 the numerous abridgements thereof, are to be found in the 

 hands of all entomologists ; or in England, where the work 

 of Stephens exists.

We are happy to perceive that many professed entomologists 

 of the present day, are using their endeavours in the most ef- 

 fectual manner, to remove the stigma of inutility which is so 

 often cast upon their favourite pursuit, by tracing, through all 

 their stages of existence, those particular species of insects 

 which are found to be injurious to the horticulturist, agricul- 

 turist, or arboriculturist. The pages of our Magazine, dining 

 the past year, have shewn that both in this country, and in 

 France, practical utility has not been lost sight of in the pro- 

 secution of the science of entomology ; and we have now to 

 notice a new work, exhibiting the same symptoms, proceed- 

 ing from M. Kollar, well and long known as one of the most 

 eminent of the Austrian entomologists. 



We cannot too strongly impress on the mind of the reader 

 that the only possible means of checking the ravages of, or 

 actually destroying, any obnoxious species of insect, must be 

 consequent upon an accurate investigation of the peculiarities 

 of its economy. This opinion is most strenuously inculcat- 

 ed in the volume before us, which is the result of a recom- 

 mendation, originating in the Royal Agricultural Society of
