tor ; in both wings the second and following branches of radial sector are bent so as 

 to appear like one straight vein running toward the tip of wing. Expanse 48 mm. 



From Pedregal, Mendoza, Argentina. 



Austroleon, new genus. 



Fore wings ; radial sector arises much before end of anal vein, the anal ends 

 nearly as far out as first fork of radial sector ; but three cross-veins basad of radial 

 sector. Hind wings ; the anal vein runs about one third the way to tip, bends down 

 suddenly, and not parallel to the very short fork of cubitus, two cross-veins basad of 

 radial sector. Legs not slender, first tarsal joint as long as next two ; spurs present, 

 as long as first two joints. In both wings there are few, if any, costals forked before 

 the stigma, and tips of all wings are sub-falcate. Neither of the species are heavily 

 marked. 



Austroleon dispar, new species. 



Face pale ; a small dark mark under each antenna ; antennae pale, second joint 

 marked with black, others with a black band, tips not very dark ; vertex with a 

 median pale brown line, a spot in front each side, and some behind, pale brown ; 

 palpi pale, last joint with a dark dot ; pronotum paler, the lower margin, a stripe each 

 side, a median stripe behind, and two elongate spots in front are black ; thorax black, 

 a submedian pair of sharply defined pale stripes, and pale stripes through bases of the 

 wings, the anterior part of the median black stripe is divided by pale ; legs pale, 

 femora heavily dotted with black, a few other dots; abdomen dark, with a faint pale 

 stripe each side for one half way out. Wings hyaline ; fore wings with the costal and 

 hind margin uniformly black, longitudinal veins pale, interrupted with black, a larger 

 dark spot at end of the median, and at end of the anal vein before it bends to the 

 margin ; stigma yellowish. Hind wings with mostly dark veins; the radius, sec'or, 

 and cubitus interrupted with pale; stigma yellowish, the apical part of all marginal 

 veinlets dark. Hind wings much narrower than fore wings ; both falcate at tips ; 

 cells between branches of radial sectors elongate. Expanse 50 to 58 mm. 



From Pedregal, Mendoza, Argentina. 



Austroleon compar, new species. 



Face pale ; palpi pale ; a pale brown mark under each antenna, and a pale 

 band above ; vertex with a transverse dark spot each side ; antennae pale, black 

 toward tips ; pronotum pale, a broad black stripe each side to lower margin, leaving 

 a very broad pale middle area ; thorax pale, a blackish stripe each side above the 

 wings, scutellum with a faint median dark line; legs pale, femora darker each side 

 toward tip, and tips of tarsal joints dark ; abdomen pale, blackish beyond the 

 middle, the tips of some of the pale segments black above. Wings hyaline ; fore 

 wings with veins interruptedly brown, the brown never extending out on the mem- 

 brane ; a dark spot near tip of the median vein; stigma pale, dark at base. Hind 

 wings similar, with dark spots less distinct : the cells between the branches of the 

 radial sector are all large, none compressed ; hind wings not so much narrower than 

 fore wings. Expanse 32-38 mm.
