organ exhibits in the whole of the animals of which the 

 class is composed. Cuviei* led the way in this branch of the 

 science, and has been followed b}^ Marcel de Serres, Herold, 

 Treviranus, Leon Dufour, Gaede, &c. ; wdiilst the the minute 

 researches of Strauss-Durckheim upon the Melolontha vul- 

 garis, and of Mr. Newjjort upon the Privet Hawk-moth, 

 published in recent volumes of the " Philosophical Transac- 

 tions," may be cited as models of patience. Besides the last- 

 named author, the English entomologist may boast of the 

 works of several other labom'crs, whose researches are not 

 inferior to those of any of the continental authors.* The 

 "Illustrations of the Genera of British Insects," published 

 by Mr. Curtis, is a work of the highest service to the science, 

 displaying not only the most minute care in the dissection 

 and delineation of the tj^pical species of the genera illustrated, 

 but also the highest style of elegance in its pictorial repre- 

 sentations ; whilst the w ork of Mr. Stephens, which may be 

 regarded as a a companion to the former, presents to us a far 

 more complete series and description of the species of insects 

 found in our own island, than any other country can boast 

 of. The " Systematic Catalogue" of the latter author, is a 

 work exhibiting the most astonishing exertion ; whilst the 

 completion of Mr. Haworth's Lepidoptera Britannica, the 

 Australian Monograph of Mr. George Gray, wdth beautiful 

 illustrations from the pencil of Mr. Charles Curtis, the English 

 translation of the " Regne Animal," by Mr. Griffith and 

 others, the work upon the Lepidoptera of Java, by Dr. 

 Horsfield, together vat\\ numerous valuable memoirs pub- 

 lished in the " Magazine of Natural History," the " Annals 

 of Philosophy," Dr. Jameson's Edinburgh Journal, the Lin- 

 naean and Zoological Society's Transactions, the Entomolo- 



* Tbe " Introduction to Entomolog-y " of Kirby and Spence has given 

 a great impulse to the science, and completely answers its title.
