484 HISTORY OF ENTOMOLOGY. 



I may observe, however, that the Internal Anatomy of 

 Insects, a branch of Entomology which on account of its 

 difficulty, from the extreme nicety required in dissecting 

 them, had before been cultivated by scarcely more than a 

 single student in an age, has now attracted numerous 

 votaries. In Germany Carus, Gaede, Herold, Posselt, 

 Ramdohr, Rifferschweils, Sprengel, and others, have dis- 

 tinguished themselves in this arena: and in France, besides 

 the illustrious Baron Cuvier (himself a host), Marcel de 

 Serres, Leon Dufour, and very recently, by his elabo- 

 rate essays On the Flight of Insects and its wonderful ap- 



du Monde], Esper (Schmetterlinge, Tagschmetterlinge\ Htibner 

 (Schmetterlinge, &c.), and Ochsenheimer's valuable Schmetterlinge 

 von Europa, with the continuation by Treitschke, will afford a use- 

 ful avenue. Meigen also, author of a most valuable work on the 

 European Diptera, is publishing at this time a work on Lepidoptera 

 under the title of Europ'dische Schmetterlinge. To the Hymeno- 

 ptera Jurine and Christian are the best guides, and to the Diptera 

 Meigen. 



With regard to works in British Entomology in general Dono- 

 van's Natural History of British Insects, and Samouelle's Entomolo- 

 gist's Useful Compendium, will be found very exce'Ient helps to the 

 student. For the British Genera, the most important work that has 

 yet appeared is Mr. John Curtis's British Entomology, in which not 

 only are the insects admirably represented, but their trophi correctly 

 delineated, accompanied by able descriptions. For the Coleoptera 

 of our country, Mr. Marsham*s Entomologia Britannica should be 

 consulted : for the Lepidoptera, the Butterflies of Lewin, Mr. Ha- 

 worth's useful Lepidoptera Britannica, and Miss Jermyn's Butterfly- 

 Collector's VadeMecum; and for the English species of Linne's genus 

 Apis, the Monographia Apum Anglits. A British Fauna Insectorum^ 

 under the title of Illustrations of British Entomology, has at length 

 been happily begun by a gentleman (J. F. Stephens, Esq.) who both 

 by his accurate knowledge of the subject, and the extent of his col- 

 lection of British Insects, is best qualified to undertake it. As far 

 as it has proceeded, it is ably executed, and possesses this advan- 

 tage, (an advantage seldom to be obtained in works published pe- 

 riodically,) that it finishes, as far as possible, as it goes.
