For the benefit of those interested, I append the following de- 

 scriptions of the several stages of the insect, adapted from my notes 

 in " Insect Life," Vol. V, p. 155, and Balletin No. 30, U. S. Dep't of 

 Agr., p. 51. 



Eggs — In irregularly shaped masses of from 20 to 50, circular, tiat, 

 pale-yellow, each with a delicate, semi-transparent, membranous bor- 

 der, over-lapping each other, fish-scale fashion. As the embryo devel- 

 ops, each eg^ acquires two minute black lines or marks. 



Larva — Newly hatched one-twentieth of an inch long, almost 

 transparent greenish-white — in second and third ages becoming more 

 opaque, but still with a very glassy-looking surface, and showing a 

 sparse dotting of black. Full-grown larv^a from eight to nine-tenths 

 of an inch long by about three-twentieths inch in diameter when crawl- 

 ing, somewhat contracted and broadened in repose. The form is sub- 

 cylindrical, tapering slightly toward either end. The color at this 

 stage is variable, in some specimens translucent pinkish, in others dull 

 green, and again of the gray-brown shade of the bark of the older 

 wood, always obscurely striped on the dorsum and sides, with a darker 

 shade of the ground color, and having a narrow but distinct ivory- 

 white stigmatal baud. Piliferous dots black, surrounded with a paler 

 ring, largest just above the stigmatal band, four in sub-dorsal spaces 

 on eleventh segment being in the hollow of conspicuous crescents 

 convex toward the sides. Head narrower than thoracic joints; cor- 

 date, with rounded lobes of a pale-brown color, with irregular stripes 

 in a somewhat darker shade; mouth parts dark-brown; legs and pro- 

 legs same color as general surface. 



Cocoon — Of various shapes, rather loose and baggy, of fine texture 

 and thin, but very strong; pinkish or brownish-white, spun against 

 some flat surface or among crumpled leaves. 



Pupa — From one-half to six-tenths inch in length ; very slender, 

 with slight corrugations, and teeth on the posterior edge of the joints, 

 and of a bright brown color. 



i/o^/i-^Expanse of wings seven-eighthslnch ; fore-wings satiny in 

 texture, of a pale, brownish-gray, sometimes, when the insect is per- 

 fectly fresh, faintly tinged with green or roseate, and always crossed 

 by three curving, wavy lines of a more dusky shade — the outer margin 

 back of the very short white fringes, being also dark; hind- wings sim 

 ilar in color to the fore- wings, but thinner, without the dark cross lines 

 but with dusky shadings on the lower edges; body long and slender 

 brownish-gray above, satiny-white beneath, with long terminal joint 

 which is upturned and tufted; head narrow, with projecting, beak 

 like palpi, margined with white, very long tongue, large hemispherical
