128 Tryon Reakirt on Coloradian Butterflies. 



Var. a, and which I consider the true male type, the other forms 

 being in process of segregation, presents a distinct sub-quadrate black 

 spot (noticed in Mr. Edward's description) about .11 inch in width, 

 in the medio-posterior interspace of the fore wings upper surface, 

 touching neither vein nor veinlet, and opposite the middle of the 

 inner margin. 



No distinct internal prolongation of black atoms, at the end of the 

 abdominal band, as delineated in Doubleday's figure ; the under side 

 agrees with Mr. Edward's diagnosis. 



Var. b, has the red costal spot small, and but a minute crimson 

 dot within the interior black spot ; sub-interno-marginal patch, small, 

 about .04 inch in width; secondaries furnished with a distinct, sub- 

 marginal row of six rounded, black dots, and both surfaces, the lower 

 similar to the upper in all respects, thickly strewn with black atoms; 

 I have seen two, of this form, the only ones in which I have observed 

 this peculiarity. 



Var. c. Crimson obsolete in the interior spot of the fore wings, 

 and but two sub-marginal spots visible upon the secondaries, but these 

 are very much larger than in the preceding. Under surface as in var. 

 b, but deprived of the sprinkled black atoms. 



Var. d. Outer margin as heavily marked as in the female; crim- 

 son centre almost obsolete in costal; and entirely so in the interior 

 spot; two small spots in the medio-posterior area, — the outer, corres- 

 ponding in situation with that found in the preceding forms, the iuner 

 midway between this and the base ; discal arc, and submarginal spots 

 (six of these) of hind wings very heavily marked, the latter becoming 

 lunulate; a very large black patch near the anal margin, correspond- 

 ing with the red mark below. 



Var. e., is similar to the above, but the dark outlines are very 

 pale, and the crimson on both surface, is lightened to pale pink ; the 

 inner sub-interno-marginal spot of the primaries is also wanting. 



Var. /., has the costal and the interior spots, distinct — discon. 

 netted ; — in all the others these are joined by a black bar of greater 

 or less width; this also, with the following, is deprived of the black 

 spot near the inner margin of the primaries — the only two agreeing in 

 this respect, with the engraving in the " Genera;" the sub-marginal 

 spots of both fore, and hind wings are very indistinct. 



Var. <j., agrees generally with the former, but with the total obso- 

 lescence of all submarginal spots. On the under side we find the 

 black interno-marginal spot of the primaries, wanting upou the upper
