THE CANADIAN ENTOMOLOGIST. 307 



Fore wing : just beyond base, above and below fold five small 

 clusters of dark scales in an irregular ring, open towards base. A broad 

 oblique central fascia is faintly outlined by two very scattering lines of 

 dark scales, the inner from inner quarter of costa to inner third on 

 dorsum, and the outer from middle of costa to dorsum before angle. 

 Regularly and closely placed on costa are small clusters of dark scales, in 

 short oblique dashes on the inner half, and short oblique lines on the 

 outer half. A small subapical dark spot, and below it a submarginal 

 cloud of darker scales between the latter and outer margin, obscurely 

 merging into central fascia. The lower two-thirds of margin are almost 

 entirely free from dark scales, and are of a pale yellowish-fuscous colour, 

 except the ocellic spot above angle, which is white, overlaid with gray. 

 Cilia same as fore wing, but slightly darker. 



' Hind wing pale fuscous, with darker fuscous scales] below outer half 

 of costa and at apex. Cilia same. All the space above vein S is closely 

 and heavily clothed with rather short black scales ; this ^is possibly a 

 sexual character. Abdomen grayish-fuscous, anal tuft bright light brown. 

 Legs yellowish fuscous, shaded with light brown. 



$ , 1 8 to 20 mm. Three specimens, each differing ^from each other 

 only in degree of darkness, and differing from the male in the absence of 

 the black subcostal streak on bind wing and in the addition of four 

 clusters of raised scales on the fore wing, three subdorsal, evenly spaced, 

 inner just beyond base and outer before angle, the fourth isTabove and 

 beyond the latter. 



Fore wing of palest 9 contains less black scales than ^ described 

 above, and the lines indicating the central fascia are almost obsolete. 

 There are three short parallel horizontal dark lines on outer margin below 

 apex, and a fourth below them traversing the ocellic spot. White scales 

 are rather freely scattered over the fore wing of this, specimen, which 

 under a low-power lens or with eye only, appears almost immaculate, of a 

 pale tan colour, with basal area, a broad oblique band beyond central 

 fascia and cilia a shade darker. 



The markings on fore wing of darkest 9 are well defined. The 

 ground-colour is white and whitish-fuscous, with streaks and spots of 

 yellowish-tan. The black scales are arranged as follows ;• A short vertical 

 streak juet beyond base connects by a line in the fold to a parallel vertical 

 streak inclined inwardly, neither touching dorsum. A rather large
