Eight specimens. Stockton, Utah, Aug. 1st to 11th, Tom Spal- 

 ding ; Utah, July, O, C. Poling ; Southwestern Colorado, July 11th 

 and 14th, W. E. Dietz ; Glenwood Springs, Colo., Aug., W. E. 

 Dietz. 



This species is closely allied to E. cramhitana AVlsra. The lines 

 of the latter are Indian red ; the upper line ends in a strong fork, 

 and the spur from lower to upper line is absent. 



Rncosma fandana sp. iiov. 



Expanse 32 mm. 



Head and thorax olivaceous-yellow; palpi and antennte pale clay color; abdo- 

 men silvery white, anal tuft pale clay; legs white, dusted with pale fuscous. 



Forewing: a light olivaceous-yellow, with two silvery-white horizontal lines. 

 The upper begins on costa at inner fourth and ends in apex, beyond the middle 

 the costa along this line is edged with yellow. The second starts at base, and 

 runs in nearly a straight line through middle of wing nearly to termen. at its 

 outer end it turns upward and points towards apex. At the extreme base the 

 white color spreads to dorsal margin. Cilia yellowish-cream. 



Hind wing: fuscous, cilia white, clouded with fuscous; underside paler fuscous, 

 white along costa. 



Underside forewing: smoky fuscous, yellowish along costa and white below 

 vein 16. 



One specimen. Denver, Colo., Oslar. 



Belongs in the same group as crambitana Wlsm. and canariana 

 Kearf , but whereas in these two species the silvery white is the 

 predominant color, in this one the reverse is the case. 



Eucosiiia spaldingana sp. nov. 



Expanse 14-20 mm. 



Head, palpi, thorax and abdomen white; anteunae pale fuscous, with a whitish 

 bloom; legs white, dusted with light brown. 



Forewing: silvery-white, with two transverse narrow bands, and patch in api- 

 cal end pale clay-yellow, rather heavily overlaid with Indian-red scales. The 

 inner line starts from inner fourth of dorsum, and reaches costa at inner third, it 

 follows costa to beyond half and again crosses wing, obliquely to dorsum, before 

 anal angle, where it broadens out and covers the outer third of dorsum. From 

 middle of wing at end of cell it sends a spur into apex, this broadens below apex 

 into a large patch covering the upper two-thirds of outer fourth, with a few 

 scattered scales continuing along termen to anal angle. On the costa, just before 

 apex, the dark color encloses a small spot of white. The male costal fold is of 

 the dark color and a small patch of same below it. Cilia white. 



Hind wing: silvery-whitish-fuscous; underside the same, cilia white. 



Underside forewing : pale clay-yellow, mottled with pale brown. 



Fourteen specimens. Stockton, Utah, June 19th to Aug. 11th; 

 all collected by Tom Spalding.
