The glistening brown egg belts encircling the smaller twigs of the tree 
are from -®; to 75 of an inch long. Sometimes the mass of eggs does not 
completely embrace the twig, though usually there is a more or less 
narrow union on one side. The ends of the egg mass curve gradually 
down to the twig, the outer eggs inclining and the outermost lying 
almost flat, in order to permit this shape. The normal egg mass of this 
insect is so thickly covered with the glutinous secretion that the indi- 
vidual eggs are invisible. ‘The young caterpillars are rarely observed

tent caterpillar. It will be noticed that when these cocoons are handled,

mingled with the silk at the time the cocoon is spun. ‘The parent 
moth is buff-colored, with two parallel oblique white lines across the 
fore wings. The female is about one third larger than the male (see 
figure 7, @, ¢).
