NYMPIIALINAE : SPEYERIA IDALIA. 537 



one in each of the prnicipal interspaces, tiiat in the lower median interspace lar- 

 gest, a little more than a third tlie width of the interspace and distant from the 

 onter border by the width of two median interspaces. In the female, however, 

 the nppermost of these spots, and to some extent tlie succeeding one, togetlier 

 with the neis:>liboring triangular costal patch of black, are merged into a general 

 wash of purplish l)lack which lills the apex of the wing as far as a line drawn 

 along the inner edge of the triangular patch to the lowest subcostal nervaile, but 

 which is varied with interspaceal dashes of white, having a powdery edge, situated 

 in two rows: an inner, composed of four spots, the upper two small and triangular, 

 the third largest and subquadrate, the fourth vague, the line of their onter edges 

 subparallel to the outer border and terminating below at the inner edge of the lower 

 sul)costal round spot; and an outer, of two small, oblong-ovate, longitudinal spots in 

 the lower subcostal interspaces, just outside the round spots ; besides these white 

 spots, the interior border of this black apex is separated by white, instead of orange, 

 from the upper portion of the mesial band, in all but the lower subcostal, and the 

 adjoining portion of the next higher interspace. The outer border is either margined 

 witli l)lack to the depth of half an interspace, and followed by sagittate spots of 

 black, seated upon the border, one in each interspace, the upper two subcostal spots 

 separated more distinctly fi'om the margin and much larger, enclosing roundish, trian- 

 gular, oi'ange spots, the uppermost often paler (J) ; or, margined much more heavily 

 Avith black (equivalent to the outer border and the sagittate spots together) and 

 including, at a general distance of half an interspace from the border, nearer below, 

 farther above, a row of eight roundish Avhite spots, longitudinal above, transverse 

 below, one in each interspace, usually increasing in size upward, the lowest double; 

 the inner border begrimed Avith dusky scales, increasing toward the tip. Sometimes, 

 at the base of the lower median and medio-submedian interspaces, or of only one of 

 them, a tortuous line is present, in broken continuity with that crossing the middle of 

 the cell ; fringe black, interrupted abruptly, bvit not very broadly, in the interspaces 

 with white. Hind icings rich purplish black, besprinkled on the basal third and espec- 

 ially In the subcostal and median area with orange scales and long hairs ; a submargi- 

 nal row of seven interspaceal orange (J") or cream colored ($) roundish spots, nar- 

 rowly edged with gray blue, decreasing in size toward the inner border, averaging 

 half the width of an interspace, their outer edges distant from the outer border by 

 more than half the width of an interspace, their borders powdery. Crossing the mid- 

 dle of the wing is an irregular series of seven similar spots, often vague in the male, 

 cream colored in both sexes, narroAvly edged with gray blue, situated in the same 

 interspaces, the middle one smallest and usually triangular; the upper four are 

 arranged in a nearly straight line from the middle of the costal border toward the tip 

 of the upper median nervule ; the fourth, fifth and sixth form a second line at right 

 angles to the first ; and the seventh falls considerably below that line, lying in the 

 middle of the apical half of its interspace; besides these there is sometimes, most 

 frequently in the female, a vague triangular patch of mingled cream colored and 

 gray blue scales, a little way beyond the extremity of the cell; fringe very dark pur- 

 plish, interrupted broadly and suddenly at the interspaces with cream white. 



Beneath : fore vnngs orange, slightly paler than above, the black stripes about the 

 cell and the mesial stripe similar to those of the upper surface, but more circum- 

 scribed; the subapical triangular black patch is also repeated, but rather as an oblique 

 bar reaching to the lower subcostal interspace ; the costal edge is black but varied 

 with silvery white streaks and spots, arranged in three transverse series; the first two 

 limited by the penultimate subcostal nervule, and composed of nearly laterally contin- 

 uous streaks ; the first is placed between the cell and the mesial stripe, the second 

 between the mesial stripe and the subapical black bar, and the third beyond it; the 

 last is composed of two or three comparatively short streaks, placed side by side, fol- 

 loAved by two greatly elongated ovate dashes in the two lower subcostal interspaces, 

 reaching as far as the sulmiarginal mai-kings ; excepting in the lower median inter- 

 space, the row of round spots crossing the middle of the apical half of the upper
