Lyoena ruberrothei A. G. Weeks, Jr. 1 



(Plate XLIII, Figure 2.) 

 Habitat : Sicasica, Bolivia. Expanse : .75 inch. 



Head, above, black, with a gray color ; beneath, white. Thorax, above, black, 

 bordered by gray beneath, nearly white. Abdomen, above, black; beneath, white 

 tinged with yellow. Legs white. Antennae, above, black ; beneath, whitish, with 

 annulations at base of each joint. Club light brown beneath. Upper side of 

 fore wing very light blackish brown, without any markings. Basal area black 

 suffusing to ground color at centre of wing. Hind margin has a very fine dark 

 thread. Nervures and nervules dark from base to near margin. Upper side of 

 hind wing same as fore wing in general coloring. Hind margin has a very dark 

 fine thread. In the interspaces at hind margin is a series of lunules, black with 

 a very light brownish border. At the upper angle these are scarcely perceptible, 

 the most prominent one situated above the lower submedian nervule. Under 

 side of fore wing very light brownish, very heavily dusted with white scales in 

 basal half of wing. There is a mere suggestion of lighter lunules in interspaces 

 at hind margin. The nervures and nervules are somewhat blackish. Under 

 side of hind wing the same, except that the dusting of white scales covers the 

 entire wing.

(Plate XLIII, Figure j.) 

 Habitat : Bolivia, near Alezuni. Expanse : .88 inch. 



Head, thorax and abdomen, above, black, with grayish hairs ; below, grayish 

 white, with yellowish tinge toward end of abdomen. Antennae, above, nearly 

 black, with white annulations at base of each joint ; below, lighter, nearly white 

 toward club. Club somewhat tawny. Legs grayish white. 



Upper side of fore wing dead grayish brown. The area bordered by a line 

 drawn from base up median nervure, thence to a point midway between end of 

 discoidal space and hind margin on first discoidal nervule, and thence straight 

 down to inner margin, shows a decided purplish lustre, evident in almost all 

 lights. The angle at apex and also at lower angle is quite sharp.
