This pine-boring Pyralid was described by Prof. A. R. Grote in a paper read at the Nashville Meeting, 1877, of the American Assoc. for the Adv. of Science, and published in Canandian Entomologist, vol. ix., 161. During the summer and autumn of 1878, and again this year, I have made some observations upon the occnrrence, larval habits and parasitic enemies of this moth, and am able to state concerning them some additional facts of interest.
