shape like the three preceding species with scale tufts; base light 

 golden ocherous with a thin dark brown costal margin and a broader 

 dark dorsal margin; the central two-thirds of the wing dark brown 

 mixed with bluish white scales, the three upper ones of which are 

 golden ocherous, while the two smaller lower ones have the same color 

 as the surrounding parts ; all the tufts, but especially the lower ones, 

 are followed by black scales. The central dark color stops on the 

 edges at apical fourth, but projects on the middle out into a sharp 

 tongue which reaches the terminal edge and separates two large 

 light golden brown round areas, the upper including apex the lower 

 surrounding tornus; these light terminal areas are sparsely edged 

 with white scales. Cilia dark brown, darkest at apex. Hindwings 

 dark blackish brown. Abdomen dark brown with ocherous anal 

 tuft. Legs dark brown; tarsi with ocherous annulation.

Related to the foregoing species, but of more complex design and

STENOMA LACTIS, new species. 

 Plate 8, fig. G. 



Labial palpi creamy white with base of second joint and tip of 

 terminal joint black. Antennae dark fuscous. Face and head 

 white. Thorax white tinted with yellow and with an ocherous pos- 

 terior tuft. Fore wings short and broad of the same shape as in 

 Stenoma mendoron; basal third ocherous white, terminal two-thirds 

 dark fuscous, the limits of the two colors sharply drawn by a slightly 

 outwardly curved pure white line from basal fourth of costa to 

 shortly before the middle of dorsum. In the dark part of the wing are 

 several small scale tufts mixed with black scales; at the end of the 

 cell is a small ocherous tuft followed by black. Cilia fuscous. Hind- 

 wings triangular, dark fuscous. Abdomen dark fuscous with ocher- 

 ous underside and anal tuft. Legs ocherous, mottled with fuscous; 

 tarsi darker with ochreous annulations.
