344 LEPIDOPTERA. 



lars are covered with coarse hairs, spreading out on all 

 sides like the bristles of a bottle-brush, and growing in 

 clusters or tufts from little warts regularly arranged in 

 transverse rows on the surface of the body. They run 

 very fast, and when handled roll themselves up almost 

 into the shape of a ball. Many of them are very destruc- 

 tive to vegetation, as, for example, the salt-marsh caterpil- 

 lar, the yellow bear-caterpillar of our gardens, and the fall 

 web-caterpillar. When about to transform, they creep into 

 the chinks of walls and fences, or hide themselves under 

 stones and fallen leaA r es, where they enclose themselves in 

 rough oval cocoons, made of hairs plucked from their own 

 bodies, interwoven with a few silken threads. The chrysalis 

 is smooth, and not hairy, and its joints are movable. 



Some of the slender-bodied Arctians, with bristle-formed 

 antennae, which are not distinctly feathered in either sex, 

 and having the feelers slender, and the tongue longer than 

 the others, come so near to the Lithosians that naturalists 

 arrange them sometimes among the latter, and sometimes 

 among the Arctians. They belong to 

 Latreille's genus Callimorpha* (meaning 

 beautiful form), one species of which in- 

 habits Massachusetts, and is called Cal- 

 limorpha militaris (Fig. 165), the soldier- 

 moth, in my Catalogue. Its fore wings 

 expand about two inches, are white, al- 

 most entirely bordered with brown, with 

 an oblique band of the same color from 

 the inner margin to the tip ; and the 



* The French naturalist?, whom I have followed, include in this genus the Eu- 

 ropean moths called Hera, Dominula, Donna, Jacobaxe, &c. Closely allied to the 

 Hera, and still more so to the militaris, is a large and fine species, which inhabits 

 the Southern States, and which I have named Callimorpha Carolina. It differs 

 from the militaris in being larger, measuring across the wins? two inches and a 

 quarter, or more, and in having the hind wings of a deep Indian-yellow or ochre 

 color, with one or two black spots near the hind margin ; the abdomen also is 

 ochre-yellow. It is possible that this may be the Clymene of Esper and Ochsen- 

 beimer, or the Colona of Hiibner, whose works I have not seeu.
