Regarding tlie early stages of this species, ^fr. L. W. Goodell writes 

 me as follows: "The eaterpillar was taken at Amherst, Mass., on the 

 chestnut, Aug. I'Olli; it was ol' a l)hiisii-green color, with a thick wrinkle on 

 each ring, tlioscM)n the tilth anil eighth thickest and light brown; on the back 

 ol' the eleventh ring are two little warts tipped with brown. When fully grown 

 .it nieasnred two inches and 1 hree-tenths of an inch in length, the body largest 

 luiar the tail and tapering to the head. Aug. 21sl, it drew a few leaves together, 

 and spun a thin, silky, pear-shaped cocoon, l)ecanie a chrysalis the 24ti), and 

 was traiislin ined to a moth Sept. 13th. The chrysalis was one inch and two- 

 tenths of an ini-li in length and bluish-white in color, ending in a flattened 

 tail, tipped with l)lack, and on each edge three small black spines, each 

 ending with a minute hook." The pu[)a is represented on plate IM, fig. 1 a. 



Feeds (»n the black Inrch ; of the color of the twig, dull brownish- 

 red, speckled considerably, and especially above, with (firty-white specks, 

 arranged very frequently in lines, either longitudinal on the sides or curved 

 forward above and becoming transverse. Head a little paler than the body; 

 labrum and feet at base whitish. On the posterior portion of the fifth, and 

 eigiith segments above, there is a transverse paler ridge bordered with black. 

 Length two inches. It forms a cocoon by spinning in the midst of a bunch 

 of leaves a close and firm cocoon of a bluntly fusiform shape, having a long 

 neck extending above and below (it hangs perpendicularly) to the end of the 

 many threads ; open at both ends by an aperture about one-tenth of an inch 

 in diameter. — (8. H. Scudder.)
