scales. Forewings of approximately even width throughout, the 

 costa slightly arched, the apical margin slightly sinuous not oblique, 

 the anal angle rounded ; greyish white, with leaden grey spots and 

 blotches ; a basal patch occupying nearly one-third of the wing, its 

 outer edge serrate throughout, is composed of an equal admixture 

 of black, leaden grey, brownish grey, ferruginous and whitish 

 scales distributed in patches, more or less blending with each 

 other ; the same colours are found in a series of scattered patches 

 following the costal margin and distributed across the wing beyond 

 the middle and towards the apex, the black prevailing in a broken 

 quadrate patch resting on the dorsal margin before the anal angle 

 and in a semicircular subapical spot, with some smaller spots below 

 it, parallel to the margin, which is blotched with ferruginous, 

 bounded inwardly by a sinuate white line, the white ground-colour 

 appearing also in a series of about seven geminated costal streaks, 

 commencing at the outer edge of the basal patch, and ending before 

 the apex ; the cilia are for the most part brownish grey broken and 

 mottled with white. Exp. aL, 25 mm. Hindwings brown ; cilia 

 greyish white, with a brown dividing line. Abdomen brownish. 

 Hind legs whitish cinereous, the tibiae thickly clothed with long 

 scales, the tarsal joints banded with grey. 



Type. ? . Mus. Wlsm. 



Hob. North Carolina (Morrison). 



A conspicuous and very distinct species of the group 

 allied to scudderiana, Clem., but surpassing that species 

 in size and distinguished from its allies by the uniformly 

 dark hindwings and rich mottling of the fore wings.

 dorsal than on the costal margin, its outer edge very oblique and 

 angulated below the costa ; a rounded dorsal patch of the same
