IIESPERIDAE: PAMPIIILIDI. 1863 



half of the band running from the costal nervure to the median in a straight line, hav- 

 ing a direction from the middle of the costal border to the tip of the upper median 

 nervule, the lower half in a direction from the outer angle of the wing to the middle 

 of the inner margin ; there are besides two spots within this : one at the lower apex of 

 the cell, the other at the extreme base of the costo-subcostal interspace, the latter 

 sometimes subconfluent with the outer spot of the same interspace ; all these spots are 

 dull, silvery white. Expanse of wings, 31-37 mm. 



This buttei-fly has been credited to a wider range of territory than can 

 perhaps be claimed for it, though it is certainly found from Pennsylvania 

 to Colorado. As the species of this genus are difficult of separation unless 

 considerable series are at hand for comparison and for the study of the ab- 

 dominal appendages, determinations by those who do not make use of 

 these means must be taken with qualification. It has been given as in- 

 habiting the Rocky Mountain district from Dakota to Arizona. Nothing 

 is known of its history, except that Mead found it in Colorado at Twin 

 Lakes in July, "generally upon or near the dwarf lupines, which grew 

 with bunch grass and low herbage, in open spaces between the plants of 

 sage brush."

Head densely tufted above with tawny and black-brown hairs, which also cover the 

 apical face of the palpi, excepting the apical joint which is wholly black-brown above, 

 tawny beneath ; rest of palpus covered with white scales like the head behind and be- 

 neath the eyes, gradually merging into tawny. Antennae black-brown above, auuu- 

 lated with tawny, beneath almost wholly tawny, the apical naked portion of the club, 

 including the crook, orange castaneous. Thorax covered above with tawuy, greenish 

 yellow and pale green hairs; beneath with soi'did pale greenish yellow; the femora 

 tawny but purple at tip and on the lower portion of the anterior side ; the tibiae and 

 tarsi dull tawny, the latter infuscated apically. 



Wings above black-brown, heavily marked with tawny, having in the males a 

 decided gleam ; in the fore wings of the female the brighter colors are mostly conflned 

 to an extra-mesial, curving, bent band broadened from above downward, bent in the 

 interspaces beyond the cell, consisting of longitudinal spots clearly interrupted by the 

 nervures, starting from the middle of the outer half of the costal border aud ending 

 with its interior edge at the middle of the submedian nervure ; in addition the apical 

 half of the cell is more or less suffused or streaked with tawny which is usually of a 

 paler color than in the male. In the male the tawny occupies almost the entire disk 

 excepting the infuscated, more or less strigate base aud reaches as far toivard the 

 outer border as would correspond to the outer limits of the extra-mesial belt of the 

 female, the outer black-brown bordering being of subequal width aud of an aver- 

 age width of two interspaces; sometimes, and especially in northern speciraeus, the
