Imago (10 : 2). Head covered above witli mingled black and greenish tawny hairs, 

 the latter often dusky at their base; beneath at the sides with straw yellow scales, 

 which pass up in a narrow band at the hinder edge of the eyes and reappear behind the 

 antennae ; tuft outside of the antennae black. Palpi whitish at base, pale canary yellow 

 toward apex, paler in tint beneath, rather profusely furnished on the sides, very pro- 

 fusely above, with long black hairs; terminal joint black, yellow beneath; antennae 

 purplisli black above posteriorly, both in front and behind serrate with a tooth of 

 tawny at the base of each joint, occasionally nearly uniting across the joints and form- 

 ing on each an annulation; beneath pale tawny, the apical three-flfths of the club, on 

 the sides as well as beneath, and the whole of the terminal joint naked and slightly 

 deeper in tint. Tongue dark slate brown, luteous at extreme base, growing a little 

 paler toward tip. 



Thorax covered above with dark brown hairs, tinged, most deeply on the prothorax 

 and patagia, with greenish tawny ; beneath with dirty yellowish, or pale tawny hairs ; 

 legs tawny buff, the basal half of the femora pale, the upper surface of the tibiae and 

 under surface of the tarsi darker, and the upper surface and sides of the tarsi dark, pur- 

 plish brown, deepest toward their tips ; spurs dull buff, dusky tipped ; spines luteo-buff; 

 claws dull reddish, dusky tipped. 



Wings above very dark brown, tinged with chocolate and marked with tawny. Fore 

 wings with a few tawny hairs close to the base in the principal interspaces. There is 

 a large tawny spot occupying nearly the whole of the cell ; its external margin is 

 straight and runs from midway between the bases of the second and third superior 

 subcostal nervules to the base of the second median nervule; in the middle of the cell 

 the spot is encroached upon by a deep, semicircular incision, reaching from above 

 nearly to the median nervure, leaving that portion of the spot which lies outside of it 

 nearly square; toward the base, the spot occupies only the lower half of the cell, 

 tapers and terminates midway between the first divarication of the median and the 

 base of the wing; beneatli the median nervure and just beneath the excision, the spot 

 is slightly enlarged by a small, triangular, tawny patch at the extreme base of the lower 

 median interspace, but separated from the cellular spot by the nervure. In the middle 

 of the outer half of the wing is a transverse, continuous, rather broad, arcuate series 

 of angulated tawny spots, separated oidy by tlie ncrvures and subparallel to the outer 

 margin, excepting in the two interspaces beyon<l the cell, where they are removeil out- 

 ward, their interior margins continuous with the exterior margin of the rest of tlie
