These terms are frequently used in economic literature, and the spots are in many cases characteristic. Taken as a whole, the species of the Noctuid family are very much alike, and no attempt will be made here to distinguish them, except in the most superficial manner. The hind wings are usually without markings, and when at rest are concealed by the fore-wings, which lie overlap- ping and covering them, either flat on the back or roof-like, a little oblique. In the early part of the series we have a number of species with hairy caterpillars that sometimes feed on shade- trees. We occasionally find a rather large yellow caterpillar, densely clothed with soft yellowish hairs and interspersed here and there a pencil of much longer, black hair.
