1338 THE BUTTERFLIES OF NEW ENGLAND. 



stripe on tlie sides of the Urst and second thoracic segments. Length about 12 mm. ; 

 breadtli of head, 2 mm. Described from alcoliolic specimens. 



Fourth stage. Head (79: G5) pale castaneous, pale beneath with the mouth parts, 

 and with a pale, oblifjue stripe crossing the upper limit of the ocellar fleUi ; ocelli pale 

 with a blackish base. The body has now assumed the form and markings of the adult, 

 excepting that the lenticles are higher, being mostly hemispherical and of a glistening, 

 f errugineo-castaneous color, that tlie lighter colors are still white and that the posterior 

 patch has a median triangular dorsal tongne of the darker color on the seventh seg- 

 ment. Length of body, 30 ram. ; breadth of head, 3 mm. From blown specimens. 



Last stage (76: IG). Mead (79: Gfi) pale castaneous as in the preceding stage, but 

 with no oblif|UC pale stripe. Body dark, rich, ferruginous brown, massively marked 

 with yellowish cream color: in front with a broad, equal, oblique stripe, crossing the 

 first, second and front half of tlie third thoracic segment, posteriorly in the middle of 

 the side of the body, in front meeting in advance of the osmateria. In the middle with 

 a saddle-like spot, formed of the union of two triangular spots, one angle at the middle 

 of the dorsum of the fifth abdominal segment, another at the front base of the first 

 pair of prolegs, and the third near, but not quite at the front edge of the second ab- 

 dominal segment just above the spiracle ; above, these two triangles blend broadly 

 along the front edge of the third abdominal segment and the color of the whole is 

 more or less obscured by a mottling of impure brownisli spots. The hinder spot oc- 

 cupies the end of the body from the front margin of the seventh abdominal segment 

 backward, much blotched with brown above, especially on the seventli segment, and 

 separated from the dark ground of the parts in advance by an oblique line running 

 from the front margin of the seventh segment at the snprastigmatal line toward the 

 medio-ventral line of the posterior edge of the eighth abdominal segment. The dorsal 

 parts of the body, on the darker ground, are pictured with cream or dull lemon yellow 

 in cloudy longitudinal streaks on the fifth and sixth abdominal segments, with duller 

 yellow in aunuli and small round spots in advance of the saddle-shaped spot, the annnli 

 at the base of the darlv, brownish ferruginous, opaque lenticles. Under surface of the 

 body between the outer side of the pi'olegs, yellow on the abdominal segments, the 

 prolegs with a basal, larger, and apical, smaller, longitudinal stripe of the dark fuligi- 

 nous which marks uniformly the infrastigmatal region, the basal stripe continuing nar- 

 rowly in front upon the segment itself. Spiracles concolorous. Osmateria deep vinous 

 red. Legs dark olivaceous, infuscated outwardly at base in transverse bands. Length, 

 5.5 mm. ; breadth of head, 4.5 mm. ; of third thoracic segment, 12 mm. ; of eighth ab- 

 dominal segment, 7 mm. Described from blown specimens. 



A specimen of a nearly full grown caterpillar shown me alive, but in a dying condi- 

 tion by Mr. B. P. Mann had the front pair of prolegs greatly aborted ; the under sur- 

 face of the third abdominal segment had only a pair of slight mammiform elevations, 

 each witli a sessile crescent of booklets ; these last could scarcely ever have been brought 

 into use, yet they were as well developed as usual ; the markings on the sides of the pro- 

 legs showed that no part was actually wanting but only that all the fleshy parts were 

 excessively shortened. 



Chrysalis (85 : 8-10). Nearly uniform dead leaf brown, sometimes witli a greenish 

 tinge, the head, prothorax and front, below the basal wing tubercle and half way across 

 the wings, darker, warmer brown, the laterodorsal tubercles of abdomen blackish brown, 

 the spiracles testaceous. Besides, the hinder edges of the movable al)dominil segments 

 are lavender, there is a broad, ol^liqne, faint cloud of brown running on either side from 

 the middle of the outer margin of the wings, toward tlie middle of tlie niesonotnm, and 

 everywhere the chrysalis is more or less marked with fine, t)lack, almost velvety black 

 lines; particularly the veins of tlie wings, at least about the cell, are marked with black 

 and atortuo-sinuous thread runs close and subparallel to the hinder margin of each ab- 

 dominal segment on the ventral as well as tlie dorsal surface. There is a blackish brown 

 stripe above from the base of the ocellar tubercles to the mesonotal wall and the 

 whole front of the mesonotal Avail is transversely variegated with continuous, slender 

 belts of black, black-brown and rich burnt umber. Cremastral hooks dark castaneous-
