THE CANADIAN ENTOMOLOGIST. 323 



a all prominent, but quite perceptible on close inspection. The basal 

 area of the wing is dusted with dark scales. 



Type. — One specimen taken August 8th, 1899. 

 Nisoniades tihoneta, sp. nov. 



Habitat: Bolivia, near La Paz. Expanse: 1.75 inches. 



Male. — Head, palpi, thorax and abdomen above, black, with 

 brownish hairs ; beneath, black, with red-brown hairs. Antennas above, 

 black ; beneath, lighter, turning to yellowish white at club. The 

 abdomen has a red-brown end. 



Fore wing above blackish-brown, with a few lighter hairs in basal 

 area. Near end of discoidal space is a jagged white spot. Midway 

 between this and apex are three subcostal interspacial white dots. On a 

 line drawn from apex down to centre of inner margin is a series of white 

 spots, five in number. The first is scarcely visible, and under it, in next 

 interspace, is a larger spot ; below this and nearer the base is another of 

 about the same size ; below this and nearer the base is another much 

 larger one ; below this and nearer the base, resting on submedian nervure, 

 is another directly under the white discoidal spot. Running from end of 

 discoidal space, starting just inside of the largest white spot, is a distinct 

 white line, ending at submedian nervure and having a background of 

 blackish brown, darker than ground colour. The hind margin has a 

 narrow fringe of hairs of ground colour, but tawny as it approaches lower 

 angle. The white spots are transparent rather than absolutely white. 



Hind wing above blackish brown, with tawnyish hairs covering basal 

 area. On a line drawn from upper angle across to the centre of inner 

 margin are four interspacial elongated transparent white spots, the first 

 under the first subcostal nervule, and the rest following in the consecutive 

 interspaces. The fringe of hind margin is tawny, narrow at upper angle, 

 but broadening towards anal angle, and becoming quite prominent. 



Under side of fore wing duplicates the white spots of upper surface, 

 the lowest spot showing more whitish. The apical area extending half 

 way toward the base is brown, tending to dark brick red. The interspaces 

 just within hind margin are heavily dusted with grayish scales from apex 

 half way down to lower angle, forming quite a prominent feature. The 

 bacal area is blackish. Fringe of hind margin is the same as on upper 

 surface. The white line of upper surface running from end of discoidal 

 space downwards does not appear on under side.
