My observations on both of these species scarcely permit me to doubt that their larvæ feed in some way on the Honey Locust (Gleditschia tricanthos), though neither of them has been bred from the larva. I have, however, met with a larva from which I have not succeeded in breeding the imago, and which I believe to be the larva of one of these species. It is a Gelechia-like, about half an inch long, with sixteen feet, and feeds inside the seed-pods of the Gleditschia, on the honey-like substance found in them, and not, so far as I have observed, on the seed.
