fine insects. For several of the species contained in this memoir I 
am indebted to D. Coffin, Esq., who on his return from Mexico most 
liberally presented me with his whole collection, formed in that 
country during a residence of considerable extent.

This species is closely allied to Sat. Aurota (Cramer, pl. 8. fig. a), 
from Surinam, but differs at once in the form of the vitreous patch 
of the hind wings. The specimen figured by Cramer is a female. 
The one represented in our illustration is a male, but I possess both 
sexes, agreeing exactly together in the markings of all the wings, and 
differing only in the female being larger, with the fore wings broader 
and almost straight along the outer margin, and the hind ones shorter 
and more regularly ovate. 
The general colour is dark fulvous, the middle portion of the wings 
being darker than the base and apex. The front of the thorax is 
marked by a narrow transverse white line, and there is a broader 
transverse one across its hind part, connected with a white streak 
running in a continuous line along the hind margin of the fore wings 
for about one quarter of their length, where it forms a strong angle 
and runs nearly to the costa; it is outwardly edged with black ; this 
is succeeded by the large vitreous patch in the centre of the wings, 
of a triangular form, the side towards the base of the wing being rather 
emarginate ; and its apex rests upon a white undulated striga run- 
ning across the wings, edged within with black, beyond which the 
wing is much irrorated with pale and grey scales, especially towards 
the costa; near the tip of the wing is a black crescent, and a patch 
composed of three small black spots in a triangle, on a fulvous ground, 
preceded by a curved white line ; the margin of the wing is ashy buff, 
traversed by a very slender, very much waved black line. 
The hind wings lave a similar-sized vitreous patch in the middle, 
its basal edge being nearly straight, preceded by an arched white line, 
outwardly edged with black and connected towards the costa with the 
strongly-waved white line (inwardly edged with black) on which the 
apex of the vitreous patch rests; the ashy buff margin of the wing 
bears a series of small black spots, followed by a very slender waved 
black line. 
On the underside the wings have the base of a rich darker brown 
colour (extending as far as the undulated transverse striga), the api- 
cal half of the wings (as well as the costa of the hind ones) being 
much paler.
