green line, each segment with six small bright rose-red elevated 
dots, and low down along each side a pale yellow line running 
lengthwise immediately above the lower row of dots, from which 
line at each of the sutures a pale yellow line extends upwards 
upon the sides and sometimes is continued across the back, the 
head and six forward feet pale bluish green; spinning a whitish 
tough oval cocoon with rounded ends, 1.75 long, with leaves 
moulded to its outer surface; dropping to the ground in autumn 
and lying among the fallen leaves through the winter, giving out 
the moth the latter part of May; this of a delicate pea-green 
color, its body coated over with soft white wool, with a brick-red 
band across its anterior part and continued outward upon the 
forward edge of the fore wings nearly to their tips; each of the 
wings with a smallish eye-like spot near the centre, and the hind 
pair with their inner angles prolonged into tails which are nearly 
as long as the wings. Width 4.50 to 5.50. 
It is a remarkable feature in the Insect Fauna of this country 
that we possess such a number of large showy moths of the group 
Attacus of Linnaeus. Though the insects of the United States 
are generally so very similar to those of Europe and in some of 
the families are identical in many of their species, we here observe 
a notable difference. Whilst that continent furnishes only the 
three kinds of Peacock, the Tau and the rare Caecigena, species 
of moderate size and but little diversified in their appearance, we 
have in the State of New-York alone eight of these elegant moths, 
nearly all of them vieing in size and magnificence with the most 
superb tropical products of this kind; and of a moiety of these the 
two sexes are so very dissimilar that in the cabinet they appear to 
form twelve distinct species. We have already presented some 
account of the Cecropia, No. 33, the Promethea, No. 80, and the 
Io, No. 81, and we here come to three others the larvae of which 
occur upon the walnut. 
Many persons on looking at these splendid insects in my collec¬ 
tion have been much surprised on being informed that they were 
captured here in the State of New-York and that they are not 
rare species. They are very seldom seen, as they fly only by 
night and repose during the day time, clinging commonly to the 
sides of trees in groves and forests. This present species is less
