9. — General coloring and marking the same as c?, except that the 

 ocelli and markings are more pronounced in some specimens. 



Hab. — Sicasica, Bolivia. 



Described from seventeen specimens taken near Sicasica in 

 October, 1899. There is great variation in the prominence of 

 the ocelli, and two figures, showing the two extremes, are at 

 least instructive. My specimens intergrade nicely from one to 

 the other. 



Syrichthus nigella sp. nov. 



Head, thorax, abdomen and antennae above, black ; beneath, nearly 

 white. Club above, black ; beneath, reddish brown. Legs white. 



Ground color of forewing nearly black. Basal area and costa near base 

 dusted with whitish scales. In subcostal interspaces near apex, are three 

 white spots. Below these in next two interspaces are two white spots 

 nearer hind margin. In interspace below these is one white spot nearer 

 base, and under the first mentioned subcostal spots. In the next three 

 lower interspaces down to submedian nervure, are three larger white 

 spots, a little nearer base. Nearer costa midway between apex and base 

 IS a white dash, and under it at end of discoidal space, a white spot. Be- 

 low this in next two interspaces are two white spots, the lower resting on 

 submedian nervure and nearer base. The hind marginal fringe is very 

 pronounced, narrower at apex than at lower angle and of pure white. 

 Inner margin edged with white. 



Upper side of hind wing of same ground color. Running from centre 

 of costa across centre of wing and ending at submedian nervure is a 

 broad band of white with irregular edges. At its central portion it 

 broadens or suffuses strongly towards the base through the discoidal 

 space. Outside of this band the area to hind margin is nearly black with 

 a line of interspacial white dots. The marginal fringe is very heavy and 

 pure white. Inner margin edged with white. 



The spots and white markings of upper surface are very distinctly 

 marked showing scarcely any suflTusion. 



The general color of the under surface is white with black or dark 

 markings. 



On forewing the white spots of upper surface are repeated. The costa 

 midway to apex is distinctly white. The area near costa between the 

 two rows of white spots is dark brownish, the darkest portion of the wing. 

 The space below lower submedian nervule to inner margin is grayish 

 white. The hind margin is touched slightly with brownish. The fringe 

 is white. 



Under side of hind wing white. Across apical area is a dash of black. 

 There is a prominent dash of black running from median nervure near 

 the hind margin across to submedian nervure. Above this and parallel
