L. Lorquini bears a strong resemblance to a local species, to be de- 

 scribed hereafter, though it is a much larger and more fully developed 

 insect; it must be regarded as the eastern representative of our species. 



2. Limacodes viridus, nov. sp. 



Male ? Expanse .94 inch. Fore wings. A dark brown spot, at the 

 base extends inwardly to the submedian nervure, follows it for one- 

 fourth its length, then crosses, parallel with the outer margin to the 

 costa. which is also brown. A. broad light brown marginal band, tra- 

 versed by darker nervures, the inner boundary of which is a rich 

 brown-velvety line, darkest towards the inner angle, and also parallel 

 with the margin. The rest of the area is pea-green. Hind wings, 

 fawn color, shading into a dark brown along the margin. Below, 

 greenish-yellow on the fore, and pale fawn on the hind wings. An- 

 tennfe, brown ; thorax, green ; face, abdomen and legs, brown. 



Female. Expanse 1.06 inches. Fore wings. A dark brown semi- 

 elliptical broad patch on the costa, curving inwardly a little beyond the 

 median nervure; the remainder of the surface excepting a brown mar- 

 ginal border, is pea-green. This border widens towards the inner angle, 

 the nervures being distinctly lined with dark brown, and has a dark 

 spot, near its middle, extending along the margin. Hind wings, fown 

 colored. Under surface and body resembling the male. 



The Larva, I can describe approximately only, having neglected to 

 fully observe its or nation. It was about three-fourths of an inch long ; 

 general color brown. Its body rises very abruptly and broad from the 

 head, which is rounded, thence tapering gradually, until within a short 

 distance of the tail, where it as suddenly descends, terminating in a 

 sharp point. There are three distinct dorsal ridges, each being fur- 

 nished with clusters and spinules. 



It feeds on the chestnut, and may be found during September. Coc- 

 coon, about half an inch long is spun on the midrib of a leaf, oval, shin- 

 ing, brownish-black; the imago appears in 3Iay. 



Philadelphia. — Much resembles the preceding species. 



3. Limacodes minuta, nov. sp. 



Male and female, are alike in color, the last being the largest. 3Iale 

 expanse 5 lines, female 5j lines. Fore wings, lustrous, brownish-yel- 

 low ; hind wings, .blackish-brown. Below, testaceous, with a black
