246 LEPIDOPTERA. 



that "this species resembles P. Asterias, but differs from it 

 in many points. In P. Asterias the palpi are edged within with 

 yellow ; in P. brevicauda they are black. P. Asterias has two 

 yellow spots above at the base of the antenna?, which are either 

 wanting, or exceedingly faint in the other species. P. Asterias 

 has a spot of bright yellow on the anterior edge of each side of 

 the thorax ; P. brevicauda has a fringe- of duller yellow, extend- 

 ing fully half the length of the thorax. On the primaries the 

 discal bar in P. Asterias is much narrower, and the inner row 

 of spots smaller and bright yellow, the upper one in the row 

 being divided ; in P. brevicauda the spots are fulvous, the upper 



side of the body black, the abdomen being furnished with two rows of yellow spots 

 corresponding with those above, with several additional spots within near the tip; 

 feet black. Primaries above brownish black, with a bar of yellow across the end 

 of the discal cell; just beyond this is a row of eight spots, extending across the 

 Aviug nearly parallel with the outer margin; the upper one, which rests on the sub- 

 costal vein, is yellow, elongated and irregular, with a blackish dot beyond the mid- 

 dle; the lower ones are fulvous ; the second and third smaller than the first and of 

 an elongated, triangular form, with the apex pointing inwards; the fourth, fifth 

 and sixth are similar in shape, but larger, the latter with its apex partially wanting; 

 the seventh spot is wider and slightly concave on both the inner and outer edges, 

 the inner edge is broken : the eighth is long, narrow and irregular, with its lower 

 edge close to the hind margin of the wing. Behind the upper spot in this row is a 

 second yellow spot nearly round. Between these and the outer margin is a second 

 row of spots, eight in number, but much smaller in size. These are all yellow, the 

 three upper ones nearly round, the lower ones more or less elongated, the lowest 

 contracted in the middle as if composed of two spots joined together; the fringe 

 of the wing is also spotted with yellow, the spots corresponding in number and 

 position with those forming the second row. 



"Secondaries above brownish black, with a row of seven large spots nearly con- 

 fluent beyond the middle, in continuation of those on primaries, all more or less 

 triangular in form, the middle ones somewhat elongated ; these spots are yellow 

 above and at the sides, fulvous from near the middle to the outer edge; the fulvous 

 marking is less distinct on the second and third spots; within the margin is a sec- 

 ond row, all yellow excepting the upper one which is tinged with fulvous; the iip- 

 per spot is oblong, the second nearly round; third, fourth and lii'th lunular, nearly 

 equal in size; the sixth similar in form, but much smaller; while the inner one is 

 irregularly concave above, holding in the cavity the eye-like spot at the anal angle. 

 On the outer edge are six yellow spots, -larger and more striking than those form- 

 ing part of the fringe on the primaries. The space between the two inner rows of 

 spots is sprinkled with metallic blue atoms. At the anal angle is a round, red spot, 

 with a black dot in it below the middle, and a crescent of bluish atoms above; 

 tails very short, scarcely one-eighth of an inch long, not more than half the 

 length of those of P. Asterias. 



"Under surface of wings somewhat paler in color, with spots corresponding to 

 those above. The upper spot of the inner row on the primaries is tinted with 

 fulvous; the spots composing the inner row on the secondaries are more decidedly 

 and uniformly fulvous ; the four upper spots in the second row are also streaked 

 with the same color; the bluish atoms between the rows are partially replaced by 

 green ones." Taken at St. John's, Newfoundland.
