the lowest submedian nervule. The black of the costa broadens to a six- 

 teenth inch in width outside the white band, turning at apex and continu- 

 ing downwards along hind margin and joining the black of the inner mar- 

 ginal area at lower angle. At the lower angle, in interspace above the 

 lowest submedian nervule, there is a mere suggestion of a dash of white 

 scales. The nervures and nervules are all black. Upper side of hind 

 wings transparent, with lustre as above noted. Costal area black. Hind 

 margin with a black border one-sixteenth inch wide, lessening and dwind- 

 ling to a thread towards submedian nervure. At apical angle there is a 

 very slight, light brownish dot. The underside of forewings is identical 

 with upper surface, except that the black portions are reddish brown, 

 bordered by a darkish thread. The inner marginal area, however, is 

 black. There is also a suggestion of three interspacial white dots at apex. 

 Underside of hind wings is the same as upper surface, except that the 

 black portions are reddish brown, bordered on the basal side by a black 

 thread. The hind margin, also, has a black thread at its edge. The brown 

 spot at upper angle on forewings is white on the under surface. Expanse 

 1.90 inches. 



Hab. — Bolivia, five days' travel north from Cochabamba. 



Described from seventeen specimens taken September 12, 

 1899. A duplicate has been found in a European collection, 

 taken also in Bolivia, but unnamed. 



Thecla infreqaens sp. nov. — 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 forewings bronzy brown, with some 

 lustre. There is an indistinct 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. Hindwings same color, except- 

 ing 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 centre of 

 wing, then downwards to median nervure and following that to hind mar- 

 gin. Hind margin has fringe as on forewings. The purplish blue area is 

 broken as it reaches hind margin by interspacial lunules of ground color. 

 Inner marginal space light gray. Underside of forewing 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 interspacial 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 gray. General ground color of hind wings, under- 

 neath, is a rich dark brown. Basal area is somewhat lighter, but with a
