frothy mass. The larva (Fig. 377) is one of the most beau- 
tiful of our caterpillars. The head and the glands on the 
sixth and seventh abdominal segments are bright vermilion- 
red. There is a velvety black dorsal band, bordered with 
yellow subdorsal stripes; and there is another yellow band 
on each side just below the spiracles. The prothorax bears 
on each side a pencil of long black hairs with plume-like 
tips; a similar brush is borne on the back of the eighth 
abdominal segment, and the first four abdominal segments 
bear dense brush-like tufts of cream-colored or white hairs. 
When this insect becomes a pest the larvae can be de¬ 
stroyed by spraying the infested trees with Paris-green water; 
or the egg-bearing cocoons can be collected during the win¬ 
ter and destroyed. These cocoons are attached to the trunks 
of the trees and to neighboring objects, or to twigs. In the 
latter case they are usually partially enclosed in a leaf. Co¬ 
coons not bearing eggs should not be destroyed, as many of 
them contain parasites. Owing to the wingless condition of 
the female this pest spreads slowly. 
The Well-marked Tussock-moth, Notolophus definita (N. 
def-i-ni'ta).—The male, like that of the preceding species, is 
of an ashy gray color; but the markings of the fore wings 
are much more distinct. The female is light brown. She 
lays her eggs in a mass on her cocoon, covering them with 
hair from her body. The larva closely resembles the pre¬ 
ceding species in the form and arrangement of its tufts of 
hair, but differs markedly in color, being almost entirely light 
yellow. There is a dusky dorsal stripe and a velvety black 
spot behind each of the tufts of the first four abdominal seg¬ 
ments. The head and the glands on the sixth and seventh 
abdominal segments are, like the body, light yellow. 
The Old Tussock-moth, Notolophus antigua (N. an-ti'qua). 
—The male is of a rust-brown color; the fore wings are 
crossed by two deeper brown bands and have a conspicuous 
white spot near the anal angle. The body of the grub-like 
female is black, clothed with yellowish white hairs; she lays
