LEPIDOPTERA. 243 



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

 tenn?e, 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 be- 

 long to Latreille's genus Callimorpha* (meaning beautiful form), 

 one species of which inhabits Massachusetts, and is called Calli- 

 morpha militarise the soldier-moth, in my Catalogue. Its fore- 

 wings expand about two inches, are white, almost entirely bor- 

 dered with brown, with an oblique band of the same color from 

 the inner margin to' the tip ; and the brown border on the front 

 margin generally has two short angular projections extending 

 backwards on the surface of the wing. The hind-wings are white, 

 and without spots. The body is white ; the head, collar, and 

 thighs bulF-yellow ; and a longitudinal brown stripe runs along the 

 lop of the back from the collar to the tail. This is a very vari- 

 able moth ; the brown markings on the fore-wings being some- 

 times very much reduced in extent, and sometimes, on the con- 

 trary, they run together so mtich that the wings appear to be 

 brown, with five large white spots. This latter variety is named 

 Callimorpha Lexoniei, by Dr. Boisduval. The caterpillar is un- 

 known to me. The caterpillars of the Callimorphas are more 

 sparingly clothed with hairs than the other Arctians ; and they are 

 generally dark colored with longitudinal yellow stripes. They 

 feed on various herbaceous and shrubby plants, and conceal 

 themselves in the daytime under leaves or stones. 



Most of the other tiger and ermine moths of Massachusetts may 

 be arranged under the general name of Arctiaf. The first of 



^ The French naturalists, whom I have followed, include in this genus the 

 European moths called Hera, Dominula, Donna, Jucohaa, &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 1 have named Callimorpha 

 Carolina. It differs from the militaris in being larger, measuring across the 

 wings 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-yeilow. It is possible that this may be the Clymene of 

 Esper and Ochsenheimer, or the Colona of Hubner, whose works I have not seen. 



t Chclonia of the French, Eyprepia of the Germans (from a Greek word signi- 

 fying preeminent beauty), and subdivided, by the English entomologists, into 

 many genera, founded on minute differences in the length of the joints of the feel- 

 ers, &.C., which it is unnecessary to regard in this treatise.
