LEPIDOP TERA. 3 I I 



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 antiqua (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
