Hob. Colorado Loveland, July, 1891 (Smith). 



This species has the form and appearance of a Stega- 

 noptycha allied to incarnatana, Hw., but is at once

 slightly shaded with pale fawn at the sides. Thorax cream- 

 coloured. Forewings cream-colour, with a reddish brown suffusion, 

 except along the costal third of the wing ; two bright oblique

 base, nearer to the base on the costal than on the dorsal margin, 

 where it blends on its inner side with the paler reddish brown 

 suffusion which precedes it ; the second arising on the middle of 

 the costal margin, reaches the dorsal margin before the anal angle, 

 sending outwards from its middle an angulated band which ends at 

 the apex, a slender broken silvery line separating its upper edge 

 from the elongate cream-coloured costal patch which fills the space 

 above it ; the ocelloid patch above the anal angle, bounded at each 

 extremity by a silvery line, is cream-coloured, containing eight jet 

 black spots in two parallel rows of four each ; cilia hoary greyish.
