The venation of the wings of a member of this family is represented by Fig- ure 350. Vein V, of the fore wings arises much nearer to vein V3 than to vein V^; there is usually an accessory cell; and the anal vein may. Fig. 350.—Wings oi A gratis ypsilon. be forked towards the base or not. On the hind wings veins II and III usually coalesce for a short distance near the base of the wing; vein V2 may be either well preserved or much weaker than the other veins; and there is considerable variation in the point of origin of this vein. In the typical Noctuids, the body is large in proportion to the size of the wings; the front wings are strong, some- what narrow, and elongated, the outer margin being shorter than the inner margin ; and when at rest, the wings are folded upon the abdomen, giving the insect a triangular out- line. The antennae are thread-like, fringed with hairs, or brush-like, rarely pectinate in the males. Two ocelli are al- most always present. The labial palpi are well developed, and in some species quite prominent. The maxillae are quite long and stout in most species. The thorax is heavy and stout. In some species the scales on the dorsal surface of the thorax are turned up more or less, forming Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Comstock, John Henry, 1849-1931; Comstock, Anna Botsford, 1854-1930. joint author.
