shining brown color common to the species. The larva 
is light yellow, variegated with three broad, black, longi- 
tudinal stripes, one on each side, the other on the top of

stripes, Dr. Melsheimer called it the zebra caterpillar. 
It does not conceal itself in the ground until it is ready 
to pupate. 
Remedies.—The common red ants capture and kill 
them. Insectivorous birds devour them. As prevention

is better than cure, we may attract the moths by little 
bonfires, and destroy them. We may attract them by 
cider, and water sweetened and flavored with vinegar. 
We may keep the larva from climbing the trees by 
fastening around them strips of tin or zinc like inverted 
funnels. Cut-worms, like other caterpillars, have de- 
stroyers in the Tachina flies, and the Ichneumons are 
their parasitic enemies. I discovered one of these climb- 
ing worms a few years ago in the very process of destruc- 
tion by parasites. The worms crawled through the skin, 
leaving no visible mark, and then spun their cocoons on
