ROUND-HEADED BORER.

Attacks the same trees under the same conditions as the flat-headed borer. The adult, [fig. 12], is about five-eighths of an inch long, brown above, with two white stripes the whole length of the back. Head and under surface grayish. It is a night flyer. The female appears about June 1, and stays until September. She deposits her eggs at night, in small incisions made angling into the bark, generally near the ground. In about two weeks they hatch, and the little borers, a, [fig. 13], begin to bore their way into the inner bark and sap-wood, leaving the bore filled with "castings," [fig. 14]. For two summers they stay in the sap-wood and do great damage, often girdling young trees. After the second winter they cut channels up into the hard wood; attaining their growth by fall, they burrow outward to the under side of the bark, and there remain until spring, changing to adults. See b, [fig. 13]. They then gnaw through the bark, and emerge about June 1 to propagate their species.

Remedies. Same as for flat-headed borer.
