OF WASHINGTON, VOLUME XII, 1910. 149 



stripes on the anterior lobe of thorax, a dark stripe above wings, and 

 middle of scutelli dark, the middle lobe of metathorax dark, with a pale 

 median spot; abdomen mostly dark, basal joint with yellow spot each 

 side, the othersegments with faint yellow side line; legs pale; third, fourth 

 and fifth tarsal joints tipped with black; tibia I with outer brown stripe, 

 tibia II with two dark marks above, all femora rather darker above. 

 Wings hyaline, venation interruptedly black and white: radial sector 

 mostly black, and the cubitus more black than white: a dark spot near 

 stigma, an oblique spot near end where cubitus and median connect, sev- 

 eral narrow clouds along the cubitus, an oblique one at the end of the 

 anal vein, and many of the marginal forks with small brown clouds; 

 hind wings scarcely marked at all. Wings moderately narrow, three 

 cross-veins before radial sector in fore wing, two in hind wing, about 

 seven branches to radial sector in each wing, both pairs acute at tips; 

 abdomen no longer than the fore wings. 

 Expanse, .'58 to 40 mm. 



From Mendoza, Argentina (Jensen-Haarup Expedition, 

 through Dr. Petersen). 



Austroleon verticalis, new species. 



Face yellow, antennal sockets margined on inner side below with 

 brown, a brown mark above the antennas, a transverse spot each side 

 on upper front near eye, a pair of submedian dots and two longitu- 

 dinal median brown spots on vertex ; antennae short, brown, basal 

 joint with brown mark below. Pronotum yellowish, a brown stripe 

 each side, with a spot in front of it, and a shorter median stripe in pos- 

 terior part; thorax with two brown spots on the anterior lobe, a median 

 brown stripe on the scutelli, a stripe over each wing brown; abdomen 

 pale, with median and lateral brown stripes; legs pale, tip of fifth 

 tarsal joint black, rest but little marked. Wings hyaline, venation 

 interruptedly brown and white, the median vein in both wings and 

 many cross-veins wholly dark; a dark spot near stigma, and one where 

 median and cubitus unite near tip of wing. Wings moderately slender; 

 three cross-veins before radial sector in the fore wing, two in the 

 hind wing; radial sector with five or six branches in both wings; fore 

 wings hardly acute at tip, rather broad there. 



Expanse, 35 mm.

Family CHRYSOPID^E. 



Of the genus AUochrysa six species are before me that may 

 be tabulated as follows: 



1. Distinct spots on wings other than stigma; inner gradate series 



extends basally 2 



No distinct spot on wings; inner gradate series not extended 



basally 4
