one end, none of the veinlets black; in hind wings the gradate veinlets 

 are more narrowly marked. Wings rather broad, acute at tips; sec- 

 ond cubital cell much shorter than the third, divisory veinlet straight, 

 ending much before the cross-vein, four cross-veins between radial sec- 

 tor and median and seven branches of radial sector beyond, in both 

 pairs; about five of six gradate veinlets in each series, the inner series 

 very irregular in position; in hind wings the radial sector unites with 

 median for less than a cell-length. 



Expanse, 35 mm. 



From San Antonio, Colombia, 1,800 meters, February 

 (Fassl). 



Chrysopa lanata, new species. 



Wholly pale greenish yellow, with some reddish on cheeks, and 

 sometimes a faint reddish mark above near eye, and a pale median 

 stripe on pronotum and thorax; legs pale; wings hyaline, venation 

 greenish, unmarked; stigma moderately distinct. Pronotum but little 

 broader than long, narrowed in front. Wings long, slender, strongly 

 acute at tips of both pairs; second cubital cell no longer than the 

 third, the divisory veinlet ending far before the cross-vein, yet the 

 small cell is about three times as long as broad; five cross-veins be- 

 tween radial sector and median, and about seven branches of the radial 

 sector beyond; about six or seven cross-veins in inner gradate series, 

 and about eight in the outer series in fore wings; usually two or three 

 branches of cubitus are forked before margin. 



Expanse, 23 to 25 mm. 



From Mendoza, Argentina (Jensen-Haaiup Expedition, 

 through Dr. Peterseu). 



Eremochrysa argentina, new species. 



Face long, pale; a black spot on each cheek under the eye; two 

 narrow dark lines on vertex, conjoined in front between the antennas, 

 second jgint in antennae dark, basal joint with a black line on the out- 

 side, basal part of the antennae dark, tips of palpi dark, pronotum 

 dark green, unmarked (except dot on anterior corner seen from side) 

 much broader than long; thorax and abdomen paler green; legs pale 

 yellowish. Wings hyaline, venation greenish, with minute dark dots 

 at base of each bristle; stigma narrow, distinct. Wings short and 

 broad, rounded at tips; the second cubital cell is very much longer 

 than the third; the divisory veinlet ends much beyond the cross- vein; 

 five or six cross-veins between radial sector and the median, only 

 three or four branches of radial sector beyond; in fore wing the radius 

 runs down parallel to tip and apparently not into the margin; only one 

 or two gradate veinlets in any wing; all cells large and subquadrate. 



Expanse, 16 to 18 mm. 



From Mendoza, Argentina (Jensen-Haarup Expedition, 

 through Dr. Esben Petersen).
