sented, and loses most of its expression in the West Indies. Darapsn* 

 Walk., is unrepresented in Prof. Poey's Collection. 



It will re(iuire a nicer critical comparison than I am able to institute 

 here, to bring out the features lost and gained, and to strike the bal- 

 ance ; sufl&cient is, perhaps, .dready adduced to decide, that we have 

 entered on a new Zoological Province in leaving the United States, 

 while for the purposes of convenience of reference, the fauna of coun- 

 tries so adjacent to our own. may be included in Zoological Catalogues 

 of the North American Continent, without any impropriety. 



*The genus Darapsa Walker, is not represented in the present Collection. 

 According to my arrangement of the North American Sphingidce, it should in- 

 augurate the Tribe Chcerocainpini. Htibner, in his " Verzeichuiss," arranges it 

 as his "Family C, Uncinati," while its affinities are plainly with Cheer ocampc 

 and allies, with analogical resemblances to Calliomma in the preceding Tribe 

 2Iacroglossini. Htibner's generic name, proposed for the two consonant spe- 

 cies — Chcerilus and Myron — has priority over Mr. Walker's, and should be re- 

 tained for our genus. The species are as follows :

Darapsa rhodocera Walker, for which Mr. Walker forms aGroup in his genus. 

 I am autoptieally unacquainted with. It appears to me to form the type of a 

 distinct genus, for which the generic name proposed by Mr. Walker might bi- 

 retained.
