LEPIDOPTERA. 
of the same color between each of tlie segments or rings, and 
it is covered with long pale yellow hairs. Others are often 
seen of a rusty or brownish yellow color, with the same black 
lines on the sides and between the rings, and they are clothed 
with foxy-red or light brown hairs. The head and ends of 
the feet are ochre-yellow, and the under side of the body 
is blackish in all the varieties. They are to be found of 
different ages and sizes from the first of June till October. 
When fully grown they are about two inches long, and then 
creep into some convenient place of shelter, make their co- 
coons, in which they remain in the chrysalis state during the 
winter, and are changed to moths in the months of May or 
June following. Some of the first broods of these caterpil- 
lars appear to come to their growth early in summer, and are 
transformed to moths by tlie end of July or tlie beginning of 
August, at which time I have repeatedly taken them in the 
winged state; but the greater part pass through their last 
change in June. The 
moth (Fig. 1G8) is fa- 
miliarly known by the 
name of the white mil- 
ler, and is often seen 
about houses. Its sci- 
entific name is Arctia 
Virginica , 18 and, as it 
nearly resembles the insects commonly called ermine-moths* 
in England, we may give to it the name of the Virginia 
ermine-moth. It is white, with a black point on the middle 
of the fore wings, and two black dots on the hind wings, one 
on the middle and the other near the posterior angle, much 
more distinct on the under than on the upper side ; there is 
a row of black dots on the top of the back, another on each 
side, and between these a longitudinal deep yellow stripe; 
the hips and thighs of the fore legs arc also ochre-yellow. 
[18 Arctia Viryinica belongs to the genus Spilo&oma. — Morris.] 
* It is most like the Arctia Urtka , but is of a much purer white color.
