On the fore wings are two small silvery Stheijopis argeiitaui. A remarkable characteristic of these moths is their exceedingly short anteimte. I have never seen the larva, and the life history of these moths is not known to me. Professor Comstock states that "the larva are nearly naked and grub-like in appearance, altliough fur- nished with sixteen legs. They feed upon wood and are found at the roots or within the stems of plants. They transform either in their burrows or in the case of those that feed outside of roots within loose cocoons.'' jS. argentomaculata I have taken in northern Ohio, while collecting with a lamp. As it circled about the room, it looked, with its long wings, a good deal like a large dragon-fly. I also found a specimen of the same species in the same locality in the daytime clinging to the under side of a blackberry leaf. ^S'. argentata (the species figured) I took at dusk in Jul}^ in South Sudbury, Mass. It was flying slowly along the road in a wooded district, and I easily caught up with it and knocked it down with my hat. I have seen species of this genus from Mexico and Brazil ; and a very large coarse-looking insect of the same genus was latel}' sent me from C'Ooktown, in Queensland, Australia. The Lasiocampians include the tent caterpillars and the lappet caterpillars. The moths belonging to this group are downy or woolly and thick-l)odied, and are distinguished b}' the lack of the loop and bristle which holds the upper and lower wings together during flight in other moths. Tlie caterpillars are soft-bodied creat- ures, almost velvety to t
