 (Plate VI, Figure 3.) 



Habitat : Bolivia, near Cusilluni. Expanse : .95 inches. 



Head, thorax and abdomen above blackish, covered with blue-gray hairs ; 

 beneath light grayish brown. Antennae black with white annulations at the 

 base of each joint. Club black. Legs light grayish brown. 



Upper side of fore wing bronzy brown with some lustre. There is an indis- 

 tinct large discoidal spot of blackish. Basal area in certain lights seems 

 brighter than rest of wing. Hind margin has a slight fringe, lighter than 

 ground color. 



Hind wing the same color, excepting lower half, which is light purplish 

 blue. The edge of this blue area is bounded by a line drawn from base along 

 subcostal nervure to center of wing, then downwards to median nervure and 

 following that to hind margin. Hind margin has fringe as on fore wing. The 

 purplish blue area is broken as it reaches hind margin by interspacial lunules 

 of ground color. Inner marginal space light gray. 



Underside of fore wing light soft brown. Hind margin has a dark thread 

 within the fringe. Beginning at costa, one quarter distance from apex to 

 base, and extending downwards to lower submedian nervule, is a line of inter- 

 spacial dark brown spots suffusing towards the base of wing. There is a 

 slight space of ground color outside of these spots, followed by a white line 

 running from apex downwards to submedian nervure, parallel to hind margin 

 and one-sixteenth inch within it. The space between this and hind margin is 

 dark brown. Inner marginal space light grey. 



General ground color of hind wing underneath is a rich dark brown. 

 Basal area is somewhat lighter, but with a dark brown spot near costa. Out- 

 side of this spot is a dash of whitish scales. Running from apex across to 

 inner margin, near its base, following contour of hind margin, is an irregular 

 dark brown line. Outside of this line the ground color lightens, being very 

 light at hind margin, dashed with whitish scales and showing a few indistinct 

 interspacial dark lines. The fringe of hind margin is nearly white. 



Taken in May, 1899. Described from three specimens in
