the body half-way across, and on this is a golden spot; two 
other golden spots are on each wing near the apex. With 
expanded wings the moth measures nearly an inch and a 
half across. 
These caterpillars are very general feeders, having 
been found on corn, sumach, rose, apple, grape, currant, 
cherry, raspberry and blackberry. Not being common, and 
much infested by parasites, it is not to be feared as a very 
noxious insect. Larva and moth are shown in Fig. 97. 
THE HAG-MOTH CATERPILLAR. 
(Phobetron pithecium A. & S.). 
This is one of the most curious caterpillars known. Its 
slug-like actions, as well as its oblong or nearly square, flat- 
tened body of a dark brown color, make it a remarkable 
object. Its body is covered with eight singular fleshy ap- 
pendages protuding from the sides. The three middle ones 
are longest, measuring about half an inch; they have their 
ends curved. When such caterpillars are roughly handled 
some or all of these fleshy horns become detached. The full 
grown larva spins a small round and compact cocoon, and 
to its outside the horns are fastened; the cocoon itself is 
usually fastened to a twig of the tree on which the cater- 
pillars feed. 
The moth is very uncommon. It is of a dusky purple- 
brown color, with ochreous patches on the back and a light 
yellow tuft on the middie pair of legs. The abdomen is 
sable, ending in a tuft of ochreous scales. The fore-wings 
are variegated with pale yellowish-brown, and crossed by 
a narrow, wavy, curyed band of the same color, edged near 
the outer margin with dark brown, and having near the 
middle a light brown spot; the antenne in the male are 
very broadly pectinated and the remarkably long and nar- 
row fore-wings are partly transparent. The hind-wings are 
sable, bordered with ochreous in the female. The moth
