34 AMERICAN LEPIDOPTERA, 



Forewing: j)ure white, this gi-ound color occurs in a broad fascia in middle of 

 wing from dorsal margin to above middle, it narrows above the middle of wing 

 and the upper third is overlaid with fuscous strigulations from costa ; there is a 

 white patch on dorsum at base below fold. There is an obscure fuscous fascia 

 from inner fourth of costa, curving inward below middle to inner fifth of dor- 

 sum, it is marked in the middle of wing by a dentate line of black-brown scales. 

 A fuscous fascia crosses wing from beyond middle of costa to dorsal margin, its 

 inner edge is obliquely outward to middle of wing, then slightly inward to dor- 

 .sum, it covers the outer third of dorsum. Beyond it on costa is a white patch in 

 which are three dark brown dots, and a larger one in apex, between each two is 

 a tiny brown dash. The ocellus is large, covering the area between the dark 

 fascia and termen, it is mottled white and fuscous, with several small clusters of 

 black scales on the inner side; above it are two curious characters in black and 

 brown scales, the outer like the small letter h, and the inner like an inverted L. 

 The cilia is mottled brown and fuscous. 



Hind wing: whitish-brown, darker at apex; cilia white, with an outer and 

 inner fuscous linfe; underside whitish, streaked with fuscous below costa, from 

 base to apex. 



Underside forewing: mottled white and fuscous, principally white below fold, 

 costal dots repeated, cilia preceded by a white line and white dashes at veins 16 

 and 4. 



Williams, Ariz. 



Type in my collection ; other specimens in U. S. Nat. Mus. 



These specimens in the National Museum have been incorrectly 

 identified as E. iuvicta Wlsm. While their general appearance is 

 similar, they can easily be separated by the Indian -red head and 

 palpi of invicta. Have thirteen specimens of the latter. 



Eiicosma palousana sp. nov. 



Expanse 20-24 mm. 



Head and thorax very pale ochre. Palpi same internally stained with fuscous 

 on outsides; tuft on second joint long and loosely scaled, extending beyond apex 

 below and concealing outer joint, except the extreme tip visible from above; 

 length beyond head a little more than the thickness of head. Antennse white, 

 annulated with fuscous. Abdomen whitish, end of anal tuft stained with light 

 fuscous. Legs j)ale ochreous. 



Forewing: costa very slightly aiched; apex shortly rounded ; termen straight 

 from 7 to 3; male costal fold, less than a quarter, narrow, ap)>ressed, scales rougli- 

 ened. 



Color: very pale ochreous, with basal and dorsal spots and streaks on costa and 

 in apical portion of a light brownish-ochreous. On dorsum, one quarter from 

 base, a narrow fascia arises, continuing obliquely with parallel sides to upper 

 edge of cell ; the basal area enclosed is giound color, and beyond this semi-fascia 

 is a broad band of ground color, outwardly defined on lower half by a brown 

 spot on dorsum before angle, this spot is broadest on dorsum and has a hump 

 above on its outer half, altogether about one-third of width of wing. The costal 

 fold is brown, si)rinkled with fuscous; the costa beyond fold is evenly marked 

 with about fifteen light brown spots, the three or four before middle are short
