Eighth Befort of the State FiyTOJWLOGisT. 171 



The caterpillar, which is beautifully marked in black and orange 

 bands (six black ones and one orange on each of the principal 

 segments) and black spots, is shown at a, in Figure 23; at e and/, the 

 delicately ribbed egg of the moth is 

 represented in enlargement, showing 

 its flattened form. In Figure 24, the 

 moth is shown. When seen, in nature, 

 in its varied and tender colors, the 

 names that it bears — both the popular 

 and the scientific, can not fail of being 

 appreciated. See Fifth Report of this ^,0. 24._The beautiful wood-nymph, 

 series, 1889, p. 181 for its description. Eudryus grata (after Riley).

The caterpillar was taken in Keene Valley, N. Y., in July, feeding 

 on the leaves of willow. At maturity it pr( sented the following 

 features : 



Length, 1.75 inch, cylindrical, slender (about one-eighth of an inch 

 broad), tapering at the extremities; velvety green. Head green, as 

 broad as the first segment, traversed mesially by a delicate red line- 

 Abdomen with a j^ellow or cream-colored line midway between the 

 doi'sum and the spiracles, edged below, interruptedly, on segments two 

 to six, with black. Spiracles bordered with orange. Setse from the 

 setiferous spots, short and inconspicuous. (See figure givtn by Dr- 

 Packard in the Fifth Report of U. S. Entomological Commission.) 



The caterpillar spun its thin cocoon between leaves attached to some 

 threads by its anal spine on the morning of July 24th; on the 

 26th, it had transformed to the pupa. The moth emerged August 

 5th — eleven days pupation. 



I had previously given the characters of this caterpillar in my 

 Entomological Contributions No. I, 1872, p. 63. The following differ- 

 ences therein fi'om the above may be noted: The yellow lateral stripe 

 is shaded beneath wnth brown; head crossed by a black stripe; pupa- 

 tion of the summer brood from fifteen to twenty days. (See, also, note 

 in IiJnt. Contrih., HI, 1874, p. 164.) 



I have taken this moth on May 6th, which was probabh^ a hibernated 

 individual. Stainton remarks of its habits in England*: "The single 

 species of this genus is well known for its hibernating faculties and
