The Nocturnal Lepidoptera have the antennae setaceous, or diminishing gradually from the base to the apex, often serrated or pectinated (fig. 94); the wings in repose are horizontal or deflexed, and the hind-wings are furnished with a "retinaculum," as in the preceding section; the pupse are mostly smooth, sometimes spiny, and often enclosed in a cocoon.
