THE BUTTERI-IJKS OF NEW EXfiLAND. 



wliitisli or straw-yellow dashes, increasing in size away from tlie costal bonier, situated 

 between tlie terminal l)ranchcs of tlie sul)c;ostal ncrvnre, jnst below tlie termination of 

 the second nervule, their inner edges at risbt angles to the costal border; also with 

 two larger, similarly colored spots, the upper truncate, wedge-shaped, the lower sub- 

 quadrate, in the lower median interspaces, not far from their base, the outer edge of 

 tlie lower on a line with the inner edge of the upper; occasionally a few colored 

 scales are seen in the discoidal cell a little within the lower of these two spots. Hind 

 wings of female with a discal roM' of four yellowish orange, subquadrate, longitudinal 

 spots, their borders obscured by a sprinkling of dusky scales, situated in tlie middle 

 of the outer half of the wing, in a diagonal row in the median and subcosto-median 

 interspaces, nearly at riglit angles to the inner border; a similar fifth spot occurs in 

 the last subcostal interspace, the outer edge of the spot on a line with the inner edge 

 of the previous spot ; the fore wings of the male are usually immaculate, but occa- 

 sionally the markings of the female are indicated by a few tawny scales ; the hind 

 wings are immaculate. 



Beneath, /o>'e wings sliglitly lustrous, dusky brown, the costal and outer border, espec- 

 ially near tip of wing, sometimes rather broadly bordered with dark reddish tawny, on 

 the outer border cut across by dusky at the veins, and sometimes edged faintly with 

 dusky. The markings of the upper surface of the female are generally repeated 

 beneath in both sexes (sometimes enlarged) as yellowish orange or straw yellow spots, 

 and tliere is sometimes an additional spot in the cell, directly over the one mentioned; 

 the fringe is of the color of the outer liorder, a little more dusky at the tip. Hind 

 toinj's with a very liirge central spot of bright straw yellow, occupying the whole of 

 the space betiveen the subcostal and median veins, from the base nearly to the border 

 of the wing; occupying also the basal half of the median interspaces, except a minute 

 portion at the very base and a longitudinal quadrate patcli in the middle of the lower 

 subcostal interspace ; usually it also occupies, to a greater or less extent, a quadrate 

 patch in the interspaces above and below this delimitation, but is frequently obscured 

 to a greater or less degree b}' tawny scales ; this common central spot is marked w-ith 

 fulvous or tawny at the extremity of the cell and where the nervures cross it ; outside 

 of this spot the wing is sometimes wholly blackish brown (in specimens having the 

 fore wings nearly unlcolorous) , the outer margin with a few tawny scales sprinkled 

 over it, especially on its lower half ; but usually the costal border and the outer mar- 

 gin as far as the last median nervule are blackish, enlivened by a rather profuse 

 sprinkling of tawny scales, especially along the outer border, and here particularly 

 just next the border, which is marked by a dusky line ; the inner border and lower por- 

 tion of the outer border are also blackish beneath, but are so obscured by orange tawny 

 and bright yellowish scales as to give them a grayish pale tawny appearance; fringe 

 in general partaking of the color of the adjoining part of the wing, or a little lighter. 



Abdomen blackish purple, with a few scattered tawny hairs, especially next the 

 sides ; at tip with abundant tawny hairs ; sides above like the upper surface, with 

 more frequent tawny hairs, below becoming still more frequent, the last two or three 

 joints almost entirely tawny; beneath tawny, obscured near the base by pale, dirty 

 yellow. Upper organ of male appendages (37 .-8, I'J) three and one-half times as long 

 as broad, of equal breadth throughout, covered with moderately long, spreading hairs; 

 hooks directed horizontally backward, less than one-third as long as the centrum, 

 blunt; lateral arms forming a plate appressed to the hooks, rounded or slightly angu- 

 lated at the tip. Clasps twice as long as broad, the upper lobe high, rounded, a little 

 incurved, the lower posterior angle much rounded oil", the upper produced slightly to 

 an incurved point.
