roof the outer edges of the hind wings protruding more or less from under the 
outer edge of the fore ones. The legs arc heavily clothed exteriorly with tufts 
of long snowy white hairs, the forward shanks having a tuft of blackish ones 
on their insides at the base. 
The female (plate 2, fig. 6) is quite unlike the male, being much larger and 
differently colored. It has a peculiarly delicate or mellow appearance, from 
the softness of its colors and the thinness and translucency of its wings. The 
latter when extended measure an inch and a half or slightly less. Their hind 
edge is occupied by a slender white band or line. Forward of this is a narrow 
pale dusky band which is abruptly widened near its middle to double its usual 
breadth, this widened part occupying two of the intestines between the veins. 
This band is margined on its anterior side by a white line, by which it is sepa 
rated from a much broader and more dusky band, which is waved in its mid¬ 
dle in conformity with the dilation in the narrow band behind it. Forward of 
this the wings are milk white, crossed by four very faint equidistant wavy 
bands of the same delicate pale dusky hue with those behind, these bands being 
often obsolete upon the middle of the wing and distinct at their ends only. 
The veins arc prominent and white, forming slender lines of this color crossing 
all the bands. The hind wings are of the same soft dusky tint as the bands 
on the fore wings, but more pale, and on their hind margin is a white line or 
slender band. The hind edge of both pairs of wings is perfectly entire as in 
the male, and their fringe is pale dusky, on the fore wings crossed with white 
lines at the tips of the veins. The body is clothed with incumbent milk white 
hairs, the tip of the abdomen having a pale brown tuft, and the crest on the 
base of the thorax appears like a large elevated blackish spot. The antennas 
in this sex (fig. 6 o) are very slightly crooked in their middles, and their 
branches though equally thick with those of the males, are much shorter, be¬ 
ing but about four times as long as the diameter of their stalk. These branches 
are longest in the middle, and are gradually shorter from thence, both towards 
the base and the tips. 
This insect belongs to the Order Lepidoptera and the Family 
Bombycidje. Those European caterpillars which have the sides 
of their bodies projecting in lappets such as the larva of this 
species presents form a genus to which the name Gastropacha 
has been given, and it is to this genus that Dr. Harris refers 
the two American species of lappet caterpillars which have 
already been alluded to. One of these, named Americana by 
Dr. Harris (the Ilicifolia of Abbot and Smith, but not the 
species thus named by Linnaeus) in its colors and other charac¬ 
ters is intimately related to the European species of Gastropacha. 
The other, originally named Bombyx Velleda by Stoll, closely 
coincides with the insect which we have now described, and 
differs like it from the other insects included in the genus Gas¬ 
tropacha in several important points. It has the same singular
