HISTOKY 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 ct aucta of Fabricius, and its Siqyplement ; 
to the volumes he subsequently published under the titles Systema 
Eleutheratorum, Rltyngotorum, Glossalorum, Piezatoruvi, and Antlia- 
torum ; to the Genera Crustaceorum et Insectorum of Latreille ; to the 
same department of the Rcgne Animal of Cuvier ; and to the Animaux 
sans Vertebres of Lamarck. He will find the genera of Linne and Fa- 
bricius illustrated by figures, in Rcemer's Genera ; and many of the 
species described by the latter in Coquebert's Illustralio 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 Fauna? Insectorum Germanicce Initia has little short of 
3000 figures of insects of every Order (a considerable number of 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 Eejean ; 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 Stoli's Spectres, Mantes, Sautcrelles, Grillons, Blattes, 
Cigales, and Punaises. To a knowledge of the species of Lepidoptera,
