Owlet moths; with short bodies; fore wings usually gray and ornamented by two spots and zigzag lines which at rest cover the frequently (as in Catocala''') brightly colored hind wings; 1800 species in U. S. Hypena humuli* hop worm; Aletia argillacea* cotton worm; Lcncatiia unipunctala* army worm; cut worms. Sub Order IV. BOMBYCINA, silk worms. Body large, woolly, usually broad dull-colored wings; occasionally lacking in females; proboscis frecjuently rudimentary; antennje long, pectinate; larvte with well-developed spinning powers. Most important is the silk worm [Bombyx mori'^-), native of China; others, like Tdea polyphemiis* furnish silk of. â Everyx myroii (from Riley). value.

Hawk moths (iig. 489), body long, stout; fore wings long, slen- der, hind wings shorter; proboscis very long; antennae short; larva; naked, with a caudal spine (fig. 459). Phlegcthonihis,'* tomato and tobacco worms. Sesiid^e, 'clear wings,' resemble bees and wasps. Sub Order VI. RHOPALOCERA, butterflies. Body slender; wings held vertically when at rest, proboscis long; antennae clubbed at the tip; larva; usually spiny; puoae hung by a thread, never a cocoon. Species numerous. Vanessa antiapa* lives over winter; Pieris* attack cabbages, etc.; Papilio* swallow tails. Class V. Diplopoda (Chilognatha). The Diplopoda are usually united with the Chilopoda in a group of Myriapoda; but while they agree in having a head followed by numerous foot-bearing segments, they differ so greatly that no union is possible. The body is nearly cylindrical, although in Polydesmids lateral outgrowths give it a flattened appearance; t
