HISTORY OF ENTOMOLOGY. 483 



quire a volume. Such was its progress and spread, that 

 in every corner of Europe the pens and pencils of able 

 and eminent men, whose works have almost all been 

 quoted in the course of our correspondence, have been 

 employed to illustrate it a . 



a It may not be unprofitable here to mention those works which 

 the Entomologist may find it most useful to consult in various de- 

 partments of the science. For descriptions of the Genera and Spe- 

 cies of insects in general, he must have recourse to the Entomologia 

 Systematica emendata et aucta of Fabricitis, and its Supplement ; 

 to the volumes he subsequently published under the titles Systema 

 Eleutheratorum, Rhyngotorum, Glossatorum, Piczatorum, and Antlia- 

 torum ; to the Genera Crustaceorum et Insectorum of Latreille ; to the 

 same department of the Regne Animal of Cuvier ; and to the Animaux 

 sans Vcrtebres of Lamarck. He will find the genera of Linne and Fa- 

 bricius illustrated by figures, in Roomer's Genera ; and many of the 

 species described by the latter inCoquebert's Illustratio Iconographica. 

 In our countryman Drury's beautiful Illustrations of Natural History, 

 a large number of new and rare insects are depicted ; and in Mr. Do- 

 novan's Insects of China, India, and New Holland, some of the most 

 brilliant and interesting that have been imported from those coun- 

 tries. Panzer's Faunce Insectorum Germanicce Initia has little short of 

 3000 figures of insects of every Order(a considerable numberof which 

 are found to inhabit Britain), by the celebrated Sturm ; and the 

 latter, in his Deutschlands Fauna, has illustrated many Coleopterous 

 genera analytically (as has also M. Clairville the weevils and Preda- 

 ceous beetles of Switzerland in his Entomologie Helvetique} by his 

 admirable pencil. Beetles in general are well figured and described 

 in Olivier's splendid Entomologie ; as are those of Europe in a beau- 

 tiful work now in course of publication, under the title of Cole- 

 opteres d? Europe, by MM. Latreille and Dejean. The latter author 

 has also begun a work on this Order under the title of Species gene- 

 ral des Coleopteres de la Collection de M. Le Comte Dejean ; two 

 volumes of which have appeared, containing part of the Carabici Latr. 

 but I fear it has stopped for want of encouragement. Had the de- 

 scriptions been less verbose it would have had a better chance of 

 success. For the Orthoptera and Hemiptera, the student must have 

 recourse to Stoll's Spectres, Mantes, Sauterettes, Grillons, Blattes, 

 Cigales, and Punaises. To a knowledge of the species of Lepidoptera, 

 the admirable figures of Cramer (Papillons Exotiques de trois Parties
