described many of our hymenopters. Hiibner, Cramer, Madam 

 Merian, and more lately Herrich-Schseffer, Doubleday and West- 

 wood, have published large illustrated works, containing many of 

 our Lepidoptera. Guenee has published five illustrated volumes 

 where hundreds of our moths are first described. Likewise, for 

 the Diptera, the special works of Desvoidy, Macquart, Meigen, 

 Wiedemann, Zetterstett and Loew, are necessary to identify North 

 American flies. 



For Coleoptera, which have been largely described abroad, the 

 standard authors are still more numerous. The names of Aube, 

 Bonelli, Erichson, Dalman, Dejean, lUiger, Klug, Knoch, Eschs- 

 choltz, Forster, Germar, Gravenhorst, Guerin, Hope, Lacordaire, 

 Newman, Paykull and Schonherr, can only be mentioned. Bur- 

 meister in his Hand-book of Entomology has described many of 

 our beetles, Orthoptera, Neuroptera and some Hemiptera. Stoll, 

 Herrich-Schaeffer, Hahn and Haliday have also described more 

 Hemiptera. Serville, in his Natural History of Orthoptera, men- 

 tions many American grasshoppers. There is also the general 

 work of Rambur published like those of St. Fargeau, Macquart, 

 Guenee and Serville, in the Suite a Buffon in Paris, with those of 

 De Selys Longcamp on Libellulidae. Pictet has written on the 

 Perlidae and Ephemeridae, while several papers of Hagen treat of 

 the Neuroptera. The British Museum is publishing catalogues 

 of the various suborders containing great numbers of American 

 insects. 



Of those works treating of American insects exclusively, the 

 rare and costly work of Smith and Abbot on the Rarer Lepidop- 

 terous Insects of Georgia, delineates the metamorphosis of many 

 southern butterflies and moths. More lately Boisduval and Le 

 Conte issued an Iconography of North American butterflies, 

 giving drawings of the metamorphosis of many species. This 

 important work leaves the Hesperidae unfinished. In 1817-18, 

 Thomas Say published his American Entomology, which 'includes 

 insects of all the suborders, in three finely illustrated 8vo. vol- 

 umes, accompanied with a glossary. This, with Say's miscellan- 

 eous papers, which chiefly appeared in the Journal of the Philadel- 

 phia Academy of Natural Sciences, have been re-printed under the 

 care of Dr. Le Conte. Through the Transactions of the American 

 Philosophical Society, the Journal and Proceedings of the Phila- 

 delphia Academy of Natural Sciences, the Annals of the New York
