rowly pale; abdomen dull black, last few segments pale at tips, last seg- 

 ment with a pale spot each side, legs pale, femora mostly black, except 

 base and tip, tibia I black on outer side, tibia III black beneath, tarsi 

 blackish on tips of joints, spurs not as long as basal joint. Wings hya- 

 line, venation interruptedly black and white, the cubitus of hind wings 

 mostly black, stigma indistinct, pale. Wings slender, subfalcate at tips; 

 seven cross-veins before radial sector in the fore wings, five before ra- 

 dial sector in hind wings; about ten branches to radial sector in each 

 wing; in both pairs the anal runs parallel to fork of cuditus only a very 

 short distance. 



Expanse, 50 to 52 mm.

Austroleon frontalis, new species. 



Face yellow; a black band above and one below antennas; vertex 

 brown, rather paler each side behind; basal joint of antennae with brown 

 band below, rest of antennas brown; pronotum dark brown, with narrow 

 median pale line, broadened in the middle, and in front a round pale 

 spot each side, a pale spot or streak on each posterior side; rest of thorax 

 dark brown, with pale spots; two on anterior lobe, two larger behind 

 these, a small one over base of each wing, two on mesoscutellum, two 

 on metathorax, and two on metascutellum. Abdomen brown, faintly paler 

 at tips, and a spot on middle of the seventh segment above. Legs pale, 

 banded with black on the tibias; second, third, and fourth and apical 

 part of fifth tarsal joints black; femora I brown, II and III banded be-

 vein in the fore wings, also one under stigma, and an oblique one be- 

 hind this near the hind border; stigma in both wings white, black at 

 base. Wings rather slender, subfalcate at tips; three cross-veins before 

 radial sector in the fore-wings, two in the hind wings; anal ends below 

 first fork of radial sector, radial sector with six branches in fore wings, 

 five in hind wings; all costal cross-veins simple. Abdomen of female 

 short; of male long and slender, with appendages nearly twice as long as

Austroleon dorsalis, new species. 



Face pale, only a very small dark mark under the antennal sockets, a 

 brown band above antenna; from eye to eye, a broader band across ver- 

 tex, longitudinally striated and divided'in the middle by a furrow: basal 

 joint of antennas with a brown band below; pronotum pale, a brown 

 stripe each side, and a shorter median one, the lateral stripes in front 

 curve toward each other and back toward the median stripe; two dark
