NYMPHALINAE: POLYGONIA COINIMA. 337 



alxlominal sesmeiits, and sometimes the tips of some of the dorsal ones in the same 

 vicinity, which arc Avhite; hairs dnsl<y pellucid. Legs black; prolegs, excepting at 

 base, dusky. Length, 8 ram. 



Fourth stage. Head piceous, the coronal tubercles l)lack, the papillae white or 

 black, the white predominating. Body black, the segments crossed posteriorly by two 

 or three more or less slender white lines, sometimes broadening into spots, and ante- 

 riorly by an oblique whitish bar, extending backAvard on either side from the outer 

 base of the dorsal sjiines; an infrastigmatal yellow band, above which an oblitjue l)ar, 

 and some minute white spots on the posterior part of each segment. Spines of dorsal 

 series always, and of laterodorsal usually, white, the others varial)ly black or white; 

 spiracles black, with a distinct white annulus. Length, 10 mm. (After Edwards.) 



FiJ'th stari(' (74 : 38). Head (78 : ;5G) light pea-green, the summit spine mostly black, 

 very stout and not long, the lateral spinules emitted near the middle, the basal half 

 nearly as broad as long, the spinules stout and of equal length with the apical half of 

 the main stem; tubercles usually spiniform, sometimes hemispherical, pellucid, each 

 tipped with a long white bristle ; ocelli and mouth parts black. Body light pea-green, 

 Avith yelloAvish blotches which predominate upon most of the abdomen ; tliere is a 

 small spot of a dull, dark, orange color just in front of and above the laterostigmatal 

 spines of the fourth to sixth abdominal segments. Spines furnished with a wreath of 

 five spinules, which are placed at an angle of about 60° with the apical portion of the 

 stem ; below them are seldom more than one or two spinules of any magnitude, and 

 this portion of the main stem is covered with short, exceedingly delicate pile ; they as 

 Avell as the spinules are generally colorless, and the bristles black, but sometimes the 

 terminal half of the spinules is also black ; the spiniform tubercles are white or green- 

 ish. Spiracles black. Legs pale testaceous. Length, 25 mm. 



Chrysalis (83:27,29, 30,39,46-48). Nearly uniform pale wood brown, tinged, 

 especially in certain lights, with pale green and streaked very faintly across the 

 middle of the wings Avith the same; tongue and legs faintly tinged Avith pale salmon, 

 the tongue infuscated at tip, the legs interrupted with pale green; joints of antennae 

 marked Avith faint fuscous lines; ocellar tubercles conical, pointed, pretty regular, 

 the outer margin continuous Avith the sides of the prothorax, the inner inclined 

 toAvard each other at nearly a right angle, although they do not meet but form an 

 angle of 130° with the front of the head ; the tubercles above and the thoracic ridge 

 marked Avith greenish fuscous ; mesonotal tubercle moderately high, much the highest 

 posteriorly, where it is about half as high as long, posterior border straight and 

 nearly perpendicular, perhaps turned forward a little, anterior border curving regularly 

 and broadly up to the highest point ; middle of each half of metathorax and of the first 

 to third abdominal segments Avith a large mercurial spot, that of the metathorax 

 largest and centred Avith blackish, that of the second segment situated on the poste- 

 rior half of the tubercle, that of the third segment faint and difl'used ; all excepting 

 the last bounded, laterally at least, by fuscous lines ; beyond a slightly paler dorsal band, 

 made more conspicuous by a broAvnish fuscous line Avhich edges it ; posterior surface 

 of the laterodorsal tubercles edged on either side Avith brownish fuscous streaks ; a 

 stigmatal, open, broAvnish fuscous band, tinged Avith greenish and much more dis- 

 tinctly marked along its under border; on the fifth and sixth segments, a slightly 

 infuscated ventral band, edged more distinctly with fuscous ; outer edges of the cre- 

 master black; spiracles pale brown Avitli black lips. Length, 21 mm; height at 

 thorax, 7.25 mm. ; height at first abdominal segment, 5 mm. 



Distribution (20: 2). This eastern buttei-fly is one of the character- 

 istic members of the Alleghanian fsuma ; toAvard the south it is found abun- 

 dantly in the KanaAvha and ElkKiver valleys of West Virginia (EdAvards) 

 and occurs about Louis Aille, Ivy. (Belknap, Yale Coll. Mus.), and in 

 North Carolina and Tennessee (EdAvards) ; westAvard it has been taken in
