expanse of the male is generally a little less than an inch; of the 
female, a little more. 
The moth closely resembles (Parasa) Euclea chloris H.-S., for 
which it has often been mistaken. 1 
THE EGG. 
> 
The egg is described by Dr. H. G. Dyar as follows : 
Singly, or in small groups, slightly imbricated. Elliptical, flattened, translu- ^ 
cent pale ochre-yellow on glass, 1.5 by 9 mm. ; reticulations obscure, possibly 
only in a strong light, rounded hexagonally, nearly linear, somewhat irregular. 
No special characters. They hatch in nine days. \

THE LARVA. 
-...;■. i 
The following is descriptive of the larval forms received from 
"West Virginia and Maryland, but according to other describers the ? 
general color varies from red to sulphur-yellow. 
The penultimate stage. — In the penultimate stage the larva closely 
resembles the mature form, but the prominent spine-bearing processes 
are paler and less reddish, being chiefly of a dull lemon-yellow color, ( 
with the exception of the small lateral spiny tufts, which are orange 
at the base. Between the third and fourth processes the dorso-lateral 
stripes are distinctly carmine. The length of the slug-caterpillar at 
this stage is about half an inch or a little more. 
The full-grown larva. — The full-grown larva looks very unlike 
any common species with which it could be compared, but in the 
general arrangement of its spines it resembles Sibine stimulea. Its 
form is similar, but the general impression as to color is orange, 
which is the color of the principal spine-bearing processes, of which 
there are seven pairs, as follows: Two in front, two behind, one 
pair in the middle, a shorter pair proceeding from the first thoracic -• 
segment just above the head, and the seventh pair proceeding from the , 
second thoracic segment on each side. There is a dorso-lateral 
vermilion-scarlet stripe bearing six pairs of moderately long spinous ' 
processes and four rosette-like spinous tufts. There is also a lateral z 
red stripe and a sublateral red stripe bearing nine rosette-like spi- 
nous tufts. The thin violet or mauve lines, in the middle of the back, 
as shown in figure 1, c, alternate with white. The length is about h 
three-fourths of an inch. 
THE PUPA AND COCOON. 
A 
The pupa (fig. 1. /) is so similar to that of Sibine stimulea that a 
detailed description is not necessary for present purposes. It is a / 
trifle smaller than the latter, and in its early stage pale yellow with A
