squash bug.* For the former I know of no better preventive 
in the home garden than the use of some mechanical protective 
covering like cheese-cloth, or other thin, cheap cloth, over the 
plants. For the latter the simplest remedy is to trap the bugs 
under shingles or large chips placed near the plants, and then 
early in the morning to kill the bugs that seek shelter beneath 
them. 
The attacks of the sixteen-legged maple-borer! have been 
noticed in a number of places in the state. This is a small, 
whitish larva that borrows through the sapwood and inner bark, 
often doing serious injury to shade trees. Unlike the ordinary

small caterpillar: it is about half an inch long; the head is 
yellow and the legs are reddish. The burrows are filled with 
brownish castings.

These borers hatch from eggs laid upon the bark, nearly 
always where the latter is cracked, bruised, or otherwise injured, 
by a small, handsome, day-flying moth having transparent wings, 
and the general form represented in Fig. 6, c; the head is red- 
dish, the thorax yellowish, and the abdomen bluish-black, more 
or less marked with yellow and having a reddish tuft at the hind 
end. The front wings are bluish black blotched with yellow. 
The larvae feed upon the sapwood and inner bark for several 
months, often girdling the tree, before becoming full grown. 
They then burrow almost through the outer bark, leaving a thin
