or less interrupted, along each side of the body, and a trans- 
verse line of the same color between each of the joints. 
Head and feet are ochre-yellow; the hairs spring trom dark 
yellow warts, of which there are ten’on each joint; those on 
joint one being scarcely visible, and those on joint twelve 
coalescing. We have two annual broods in Minnesota, the 
last passing the winter in the pupal state. The pupa is pro- 
tected by a slight cocoon, made almost entirely of the cater- 
pillar’s hair; these are chiefly held or felted together by the 
interlocking of their minute barbs, and the whole is strength- 
ened by a few silken threads. 
The bright-colored eggs, which are round and yellow, 
are deposited on the under side of leaves in large clusters, 
and hatch into small hairy caterpillars, which feed together 
for ashort time, but gradually scatter. As long as young 
they devour only the under side of the leaf, but the cor- 
responding upper surface of it soon turns yellow and 
withers. 
The moth, which is very generally called ‘‘The Miller,’ 
frequently flies into our rooms at night. It is easily recog- 
nized by its pure white color, by having the abdomen 
orange-colored above, with three rows of black spots; the 
wings possess also a few black dots, varying in number, 
there being usually two on each side of the fore and three on 
each of the hind-wings, though sometimes all the wings are 
almost immaculate, except one spot on the disk of the fore- 
wings. The antenne are white above, dark brown below; 
head and thorax are white. 
The best time to destroy these troublesome caterpillars 
is soon after they hatch, and when they are still feeding side 
by side. By making the worms drop into a vessel contain- 
ing some kerosene oil, we can kill them quickly, and as they 
curl up and drop when touched even very lightly the work 
is rapidly performed. Of course if they are very numerous 
we have to use one of the arsenical poisons. 
It is very fortunate that this species is subject to the 
attack of a number of parasites, which kill immense num-
