CLASS VIII. 

 INSECTS 



LINNAEUS united all those invertebrate animals, whose body is 

 divided into rings and which have feet consisting of different joints, 

 into a single class, that of Insects. Together with the class of 

 Kinged- Worms they make up one of the four principal groups into 



1 There is no class of animals on which more has been written than that of Insects ; 

 comp. LATREILLE, who has given a sketch of the history of Entomology (Mm. du 

 Museum, vni. 1822, pp. 461 482, also J. N. EISELT, Gesckichte, Systematik und 

 Litteratur der Insectenkunde, Leipzig, 1836, 8vo, and J. PERCHEHON, Bibliographic 

 Eutomologique, Paris, 1837, 2 vols. 8vo). As observers deserve to be named especially 

 REAUMUR (Memoires pour servir a I'Hist. des Insectes, Paris, 1734 1742, 6 vols. 4to), 

 A. J. ROESEL (Insecten-Belustigung, Niirnberg, 1746 1761, 4 vols. 4to, with excellent 

 coloured figures) and C. DE GEER (Mem pour servir a I'Hist. des Insectes, Stockholm, 

 1752 1/78, 7 vols. 4to). The anatomy was excellently treated by our great country- 

 man, SWAMMERDAM (Biblia naturae, Leiden, 1737, 2 vols. fol.), and afterwards by 

 P. LIONET (Traite anatomique de la Chenille qui ronge le bois de Saule, la Haye, 1762, 

 4to). In this part also in the present century RAMDOHR, TREVIRANUS, HEROLD, 

 BRANDT, LEON DUFOUR, STRAUS, DRUCKHEIM, BLANCHARD, NEWPORT, &c. have 

 published many important investigations. Comp. the Articles, Insectes, by AUDOUIN, 

 in the Dictionnaire classique d'llist. nat. Tom. vm. 1825, pp. 559 579? and Insecta, 

 in TODD'S Cyclopaedia of Anat. and Physiol. n. 1839, PP- ^73 994-
