the seacoast of Texas in Us northeastern Province. This maybe called 

 the Tropical Continental District. 



The synonomy adopted in the present paper is the result of personal 

 investigation, almost without exception, of all the works cited. Where 

 this has not been possible, the citation is included in quotation marks. 

 Where the species is autoptically known to us, or, in a few instances, 

 from very reliable information, the habitat is followed with a note of 

 exclamation. 



We have found Mr. Walker's notice of this Family the most useful 

 and thorough, though we have occasion to differ in certain instances 

 from the conclusions of that indefatigable Entomologist. Dr. Clemens' 

 " Synopsis" has also afforded us acceptable information as to the text; 

 the synonomy is, however, a literal and verbatim transcription from the 

 British Museum Lists in by far the greater majority of cases. Where 

 an improvement has been attempted, as in unitm^ F/n7anipelus Jycaon 

 and F. satcllitia^ it seems to have been usually at the expense of cor- 

 rectness. 



Lepisesia flavofasciata. 



Mr. Walker describes this species for the first time, in the British 

 Museum Lists, quoting Dr. Barnstou's MSS. as authority for the ge- 

 neric and specific names adopted. Dr. Clemens has omitted this refer- 

 ence to Dr. Barnston, giving Mr. Walker as the authority for the spe- 

 cific name, while copying the description from the British Museum 

 Lists, being autoptically unacquainted with the species. Mr. Grote, in 

 his introduction to his -'Notes on Cuban Sphingidie," erects the present 

 genus for it, comparing its structure with the typical European species 

 of Se-<ia. We consider its present position at the head of the Tribe, 

 authorized by the peculiarities of its structure, and are unwilling to in- 

 terrupt the continuity of the following genera by the interpolation of 

 this genus, which is so intimately allied to Sesia. The peculiarly neat 

 and elegant little species of which this genus is composed, has not been 

 very clearly described by Mr. Walker, and we give here its more detailed 

 description as follows : Black. Above, the thorax and head are clothed 

 with pale yellowish-sericeous, erect hair, mingled with blackish scales. 

 Laterally, the palpi and the orbits of the eyes are deep black. Abdo- 

 men black, with sericeous hairs above on the basal segment. Anal 

 tuft black, with lateral sericeous sub-tufts. The anterior wings are 

 blackish with obsolete ornamentation; a rather broad, semi-diaphanous, 

 sub-terminal band, composed of sparse and whitish scales, extends 

 evenly and obliquely from costa to internal margin; the terminal por-
