The Giant Silk-worms, The large size of the members of the Saturniidae, and the ease with which the cocoons of most of the species can be collected, render them well known to every beginner in the study of entomology. The family includes our largest lepi- dopterous insects; and all of the species known to us are above medium size. They are stout-bodied, hairy moths, with more or less sunken heads, and strong, wide wings. They may be distinguished from the Citheroniidae, some of which rival them in size, by the form of the antennae of the males, and by the fact that except in the lowest genus, Coloradia^ which is a rare insect from the far West, the hind wings are furnished with only one inner vein, jn, 'Y\\^ adults fly at night, and III, ai'G attracted by lights. The head is small and deeply sunken in the thorax ; the antennae are either fili- form or pectinated in the females, but always pecti- nated in the males; and the pectinations extend to the tip. Where the antennae of both sexes are pectinated, the males can be distin- guished by the larger size of their antennae. The palpi are small, and the maxillae but little developed, often obsolete. The thorax is densely clothed with hair. The wings are broad, and are often furnished with transparent, window- like spots. The frenulum is wanting. The humeral angle.
