II. Researches into the Utility of Reptiles, either as articles of 

 food, as furnishing products for use in domestic oeconomy, or, lastly, 

 as animals of mere curiosity, hy M. Al. Guichemot (pp. 1 13-122). 



The object of this memoir is sufficiently explained by its title. 

 The author adopts the classification of M. Is. Geoffroy St. Hilaire, in 

 which useful animals are divided into five classes, namely auxiliary, 

 alimentary, industrial, accessory or ornamental, and. medicinal ani- 

 mals. The three first classes are treated of in the present number, 

 but the memoir contains nothing of sufficient importance to render it 

 advisable to present our readers with an abstract of its contents. 



III. Abstract of a first series of researches upon the insects inju- 

 rious to the rape crops, by M, Ad. Focillon (pp. 123-128). 



The principal facts contained in this paper have already been pub- 

 lished in this Journal (Ami. n. s. ix. p. 356). 



IV. Descriptions of new speq^ of Lepidoptera belonging to the 

 Entomological collections of the Museum of Paris, by M. H. Lucas. 

 First decade (pp. 128-141). 



This memoir contains descriptions of ten new species of the genus 

 Papilio, and is the first of a series of similar papers intended to form 

 a sort oi prodromus to the Catalogue of Lepidopterous insects con- 

 tained in the Museum of the " Jardin des Plantes." The descrip- 

 tions being very long and unaccompanied by diagnoses, we are unable 

 to give more than the names of the species, with the localities from 

 which they are derived, and abstracts of the remarks appended to each 

 by M. Lucas. 



1. Papilio Godartianus. Allied to P. Polydorus, Linn., but 

 smaller. Upper wings destitute of longitudinal white streaks ; lower 

 wings without red marginal lunules, and not presenting a spatulated 

 tail. Inhabits the islands of the Pacific Ocean. 



2. Papilio Celadon. Allied to P. Sinon, Fab., with which it was 

 confounded by Cramer. The tail of the posterior wings is shorter 

 than in P. Sinon, and entirely black, and the sixth green band, which 

 is macular, does not touch the posterior margin of the superior wings. 

 From North America. 



3. Papilio Arcesilaus. Allied to P. Ajax. Inhabits North 

 America. 



4. Papilio Cacicus. Allied to P. Grayi and Cleotas. From Co- 

 lumbia. 



b. Papilio Sadalus. Allied to P. Machaon and Asterias. The 

 ochreous common band of the wings is much broader than in P. As- 

 terias ; the tail of the posterior wings is black, linear, and shorter 

 than in P. Machaon. Inhabits the environs of Quito. 



6. Papilio Eurydorus. Allied to P. Proneus and Phryneus. The 

 yellowish white band of the posterior wings is much narrower, and 

 the tail, which is black and spatulate, less elongated than in those 

 species. Inhabits Brazil. 



7. Papilio Phryneus. Intermediate between P. Pronens and 

 Agavus. Inhabits Cayenne.
