from the costal nervure, just beyond the middle of the costal border and crosses the 

 flrst interspace by a line bent in an opposite way to tiiat of the interior border, crosses 

 the subcostal interspaces in the middle of their basal half by a sinuous line, the 

 subcosto-median interspace at its narrowest part (two-fifths the distance from the 

 extremity of the cell to the border) each of the median interspaces close to the base — 

 all by curved lines; the middle of the medio-submedian interspace by a zigzag line the 

 reverse of that of the interior border ; and the submedio-internal by a curved line, 

 terminating on the internal nervure close to its tip. The whole costal edge and some- 

 times the extreme base of the costo-subcostal interspaces, and the portion of the intra- 

 mesial band which Is contained in the same interspace, covered with hoai'y, 

 iridescent scales; within the intra-mesial band, the wing is cinnamoneous red, some- 

 times partially enlivened with fulvous, the cell witli a central, blackish spot, some- 

 times with a fulvous pupil and a basal, curving, l)lack line, sometimes crossing the 

 adjacent interspaces; just beyond the intra-mesial baud, the \ving is cinnamoneous; 

 beyond its extreme limit in the middle of the wing it is much beclouded with a lilac 

 flush, caused by rosaceous scales, and ornamented by a series of six, transverse, oval 

 or roundish, faint, greenish opalescent spots, edged with cinnamoneous (sometimes 

 almost entirely cinnamoneous) , subparallel to the outer border and separated from it 

 by twice the width of an interspace ; distant from the outer border by nearly the width 

 of an interspace, is a submargiual series of pretty large, sublunate, cinnamoneous 

 spots, followed by a row of similar but smaller and fainter fuscous spots; outer 

 border narrowly edged with black, the fringe dull fulvous, sometimes whitish, with 

 some fuscous scales at the nervule tips. 



Abdomen above brownish, enlivened with fulvous hairs above and scales at the sides, 

 especially at the tips of the segments; beneath dark fulvous, the tips of the segments 

 with moi'e or less yellowish. Upper organ of male (33 : 38, 39) : hook strongly 

 curved, of about the length of the centrum; tapering as in myriua but more delicately 

 bifid than there. Clasps fully twice as long as broad, exclusive of the processes; 

 tapering gently throughout, it terminates in a slender process obliquely depressed, 

 longer than l:)road, a little incurved, the extremity rounded and scarcely denticulate, 

 bearing at its innermost limit a slightly curved needle, directed forward and a little 

 inward; upper process longer than this lobe, very slender and cylindrical but de- 

 pressed and spatulate at the tip. 



Described from 2 3,6?. 



Melanic form. Mr. Walter Faxon captured a male in July and 1 have reared a 

 female in September, in both of Avhich the middle of the upper surface of the fore 

 Aviugs, included between the outer border and the mesial stripe, the inner border of 

 the bar in the middle of the outer half of the cell, and the V-shaped stripe in the 

 medio-submedian interspace (together w'ith a corresponding space on the hind wings) 

 are almost wholly and uniformly black, relieved only by slight fulvous spots or streaks 

 near the apex of the cell. The markings upon the under surface of the fore wings are 

 broader than usual, but not sufl'used as above; in no other respect did these individuals 

 ditler from the normal type. 



Secondary sexual distinctions. See the descrii)tion of the genus for a slight 

 distinction in the neuration of the hind wing. 



Egg (64 : 27). Twenty-one or twenty-two longitudinal ribs, a transverse section of 

 which is wedge shaped, elevated, of equal prominence throughout, but somewhat 

 irregular in direction and in distance apart, averaging in the latter particular .1 mm. ; 

 eight or nine of them reach the summit, the others extend only to the middle or upper
