1522 THE BUTTERFLIES OF NEW ENGLAND. 



fulvous hairs mixed with black; labriim fusco-testaceoiis with a luteous base; ocelli, 

 niaiulibles and last joint of antennae black, the ocelli tin^ted with testaceous. 



Body dull pale green, a little tinged with yellowish on the last abdominal segments, 

 and also faintly at the folds, completely and pretty uniformly flecked with pale dots, 

 which, however, form an indistinct, pale lateral line by their disposition at that point, 

 each of the dots being a wartlet from which arises a short, pale hair. The dorsal 

 shield of first thoracic segment is pallid around the margins, velvety black across the 

 middle, with amediodorsal break; in its hibernating condition it becomes concolorous 

 and the body has a roseate tinge; the prolegs are concolorous with the body, as are 

 the slightly infuscated legs, the claws of which are dusky. Laterodorsal warts 

 fuscous, pale centrally ; spiracles f usco-luteous. Length of body, 21 mm. ; breadth of 

 head, 3 mm. ; of first thoi'acic segment, 2 mm. ; of middle abdominal segments, 3.25 

 mm. 



Chrysalis (85:29, 36, 41). Chrysalis yellowish green, with brownish dorsal line, 

 and a similar ventral line on the abdomen, according to Riley. A chrysalis case 

 before me, from which the imago has escaped, is of a testaceous color, more or less 

 obscured with brownish fuscous, especially in the transverse striations upon the pos- 

 terior part of the thorax and the whole of the abdomen ; the wing cases are much 

 obscured with blackish fuliginous, as is the anterior extremity of the body; and the 

 entire surface is rendered completely hoary by a cottony, bluish white bloom ; protho- 

 racic spiracle margined with black ; the hairs, Mtiich are pretty uniformly distributed 

 over the whole body, are about as long as the abdominal segments and have a pale foxy 

 color. Length, 12 mm. ; breadth, 3.75 mm. ; length of hairs, .4 mm. 



Other descriptions of the early stages. Miss Murtfeldt sent me in 1871 the following 

 good descriptions of all the stages : — 



The egffs are about .04 inch in diameter, of a pinkish color, nearly round, indented 

 at top and beautifully ridged and punctured. They were deposited singly on the upper 

 surface of the leaves, seldom more than one upon a leaf. They hatched about August 

 20th. 



The larvae when first disclosed measured .06 inch in length, and the diameter is uni- 

 form throughout; it is of a deep orange color. The head is polished, black, and 

 much larger proportionately than at a later period in its growth. After the first molt 

 the larvae become green in color, and the surface acquires a granulated appearance; 

 the head also loses its polish, so that the young from this time differ from the 

 mature larvae in nothing except size and in being less spindle-shaped. 



The mature larvae measured from .8 to .9 inch in length, broadly fusiform, the 

 greatest diameter being .2 inch at the [fourth and fifth abdominal] segments. Head 

 free, oblique, about .11 inch in diameter, somewhat rounded in front and cordate 

 above, of a deep dull black color, roughened with minute punctures .and with a short, 

 whitish pubescence; mandibles broad, polished, black. Neck narrow, black, very much 

 constricted. First [thoracic] segment but little larger than the neck, cervical collar 

 smooth, somewhat polished, marked with a narrow, transverse black stripe inter- 

 rupted on the apex and bounded on either side by a somewhat broader stripe of green- 

 ish or cream white. The color of the remaining segments is a uniform pale, dull, 

 olive green, and the entire surface is thickly covered with minute yellowish granula- 

 tions, and under the lens with a fine, short, clubbed pubescence; a narrow, dark, 

 vescicular dorsal line can also be distinguished. Stigmata minute, pale green. Ven- 

 tral surface flattened, rather p.aler than dorsum, and not so thickly granulated. First 

 pair of thoracic legs black, or tipped with black ; second and third pair polished 

 green; prolegs concolorous with upper surface. 



The chrysalis is oblong, smooth, .5 inch in length, purple, covered with a fine white 

 powder, like the "bloom" on a dark plum or grape. It is found inside of the leaf case 

 inhabited by the larva, and is loosely enclosed in a frail, dingy white cocoon, woven 

 in very open meshes, like lace. It is suspended by the tail, and has no bands to sup- 

 port it in a particular position.
