30 AMERICAN LEPIDOPTERA. 



Oil eaf.li side of tliis outer fasciia, aud a few on the sides of the inner and many 

 others in the dark ground color between the fascia and in basal area. There is a 

 short vertical bar of leaden scales through the ocellic spot, and a few scales of 

 the same color are scattered over the apical fourth. Cilia light fuscous, preceded 

 by a darker line. 



Hiiidwing and underside of both wings very dark smoky brown, cilia pale 

 fuscous, costal spots repeated. 



Two specimens; Colorado, Gillette aud Dyar and Caudell. 

 Cotype in U. S. Nat. Mus. 



Eiicosnia inoinaiia sp. nov. 



Expanse 22 mm. 



Head and palpi clay-yellow, clouded with smoky black on bases of antennae, 

 tips of scales on collar, outer end of palpi and a spot of the same on upperside of 

 second joint of palpi near its base; thorax black, mottled with gray; abdomen 

 white, at end of each segment fuscous between ; legs white, banded and powdered 

 with black. 



Forewing: white, lightly strigulated with pale fuscous; there is an obscure 

 pale fuscous fascia at inner fourth, and much broader across wing beyond middle, 

 its inner edge starts from before middle of costa and goes in a straight line 

 obliquely to within a third of dorsum where it angles inward and reaches dor- 

 sum at outer third ; the outer edge starts from outer third of costa and curves 

 unevenly to anal angle. There is a narrow broken fascia from a quadrate black 

 spot on costa before apex, which divides in the middle of wing, one limb follow- 

 ing the termen and the other to anal angle. There is a lunate brown apical spot 

 extending into the cilia as black scales. The costal edge is white, with numerous 

 black dashes for its entire length. Cilia below apex leaden-gray, cut with three 

 or four white dashes. 



Hindwing: smoky brown, white above cell, cilia leaden, white outwardly; 

 underside the same, but a shade paler. 



Underside forewing: smoky brown, with costal and ciliate marks repeated. 



One % specimen ; Yuma Co., Ariz., desert, April lOtli, received 

 from J. B. Smith. 



Eucosma nonaiiii sp. nov. 



Expanse 24 mm. 



Head and palpi white, shaded with black over the eyes and on the sides of the 

 palpi ; antenna pale fuscous; thorax white, heavily dotted with black at base of 

 patagia ; abdomen fuscous; legs whitish, banded and dusted with black. 



Forewing: white, powdered with black and olivaceous scales. A dark shade 

 runs through middle of wing from base to apex. Between inner third and mid- 

 dle of dorsum a white line goes obliquely outward to above middle of wing, it is 

 bounded on the inside by a line of black scales; on each side of it there is a short 

 line of black in the fold. There is a row of black dots on outer half of dorsum. 

 The costa is sparsely marked with small black dots and dashes its whole length. 

 The ocellic spot is obscure, defined on inner side by a short vertical bar of shining 

 whitish scales. Cilia white, fuscous at apex and several streaks of fuscous and 

 black scales below apex. 



Hindwing: light smoky fuscous, white above cell, cilia whitish ; underside pale 

 gray, a few black dots below costa and in apex.
