STENOMA IO, new species. 

 Plate 8, fig. 2. 



Second joint of labial palpi carmine red; terminal joint dark 

 brown with yellow tip, short. Antennae reddish ochreous shaded 

 with black above. Face light carmine. Head and collar deep 

 brown. Thorax light brown with darker purple reflections. Fore- 

 wings broad, not quite two and one-half times as long as wide; 

 costa gently arched from base to apex; apex sharply pointed, some- 

 what produced; termen slightly sinuate; tornus produced, evenly 

 rounded ; dorsum straight from tornus to basal third, thence abrupt ly 

 inclined toward base; color chestnut brown, overlaid on the basal 

 two-thirds with a darker purple tint; the two shades rather sharply 

 delined by a line from about the middle of costa to the beginning of 

 the dorsal cilia. On the end of the cell lies a large irregularly tri- 

 angular ocellate spot, deep velvety brown surrounded by a thin line 

 of light yellow; obliquely below and before lies a similar smaller 

 oblong spot on the fold and on the cell is a small aggregation of dirty 

 yellow scales. Cilia short, dirty yellow with a black line parallel 

 with the edge of the wing. Hindwings bright brick red, cilia yellow- 

 ish. Abdomen and legs deep brick red. Underside of body and of 

 both wings bright brick red. 



Alar expanse. — 46 mm.

STENOMA ACRONITIS, new species. 



Plate 8, fig. 19. 



Second joint of labial palpi deep black with white tip; terminal 

 joint white, sprinkled with black. Antennae yellowish fuscous. 

 Face dirty white, sprinkled with black. Head pure white. Thorax 

 white, sprinkled with gray. Forewings short and broad with tufts 

 of raised scales; costa straight; apex rounded; termen oblique; 

 color chalky white, sparsely speckled with brown atoms and with 

 blackish brown design; from basal fourth of costa runs a blackish 

 brown streak in over the cell, outwardly, through the end of the cell, 

 toward the middle of termen, but dividing shortly before the edge 

 into two branches, of which one curves upward to a black, triangular, 

 costal spot at apical fourth, while the other curves downwards and 

 ends on the dorsal edge before tornus; the streak is not continuous, 

 but is interrupted and enlarged at its entrance into the cell and at 

 the end of the cell; between its base and the aforementioned large
