Chry!!«opa luarginalis n. sp. — Ht-ad yellowish, a brown mark each side 

 from eye to mouth ; anteiiriie yellowish ; thorax green, paler along the middle ; 

 abdomen greenish; legs yellowish; wings hyaline, venation green, except that 

 most of the cross-veinlets are marked with brown at ends; in forewing the 

 cross-veinlets (except the costals), the branches of radial sector, and the vein- 

 lets along hind margin are plainly margined with brown ; in the hind wings the 

 outer gradate veinlets are wholly brown. The forewings are rather broad be- 

 yond middle (much broader than in C. rufilabris) and barely pointed at tips; the 

 divisory veinlet of third cubital cell ends beyond the cross-vein. Length 14 mm. 



One specimen from the mountains near Claremont, California 

 (Baker). Distinguished by the brown margins of cross veinlets in 

 forewing. 



Chrysopa robiista n. sp. — Head broad, pale yellow, a red stripe each 

 side un cheeks; antennse wholly pale, close together at base, rather short ; ver- 

 tex low and flat, scarcely as high as the eyes in the middle; prothorax very 

 broad, narrowed in front, reddish on sides, leaving a broad, median, yellowish 

 stripe, with parallel sides; rest of thorax and the abdomen very broad and heavy 

 ( much broader than in other species) ; the mesothorax with a reddish dot each side 

 near front; abdomen brown towards tip; legs pale yellowish. Wings hyaline, 

 with pale greenish venation, maiked with black at bases and tips of many cross- 

 veins, the gradate veinlets wholly black, and the costals only at the subcosta; 

 pterostigma rather distinct; hindwings similar to fore pair. Forewings rather 

 loug, rounded at tips ; about eight or ten gradate veinlets in each series ; the third 

 cubital cell is about one and one-half times longer than broad, the divisoiy vein- 

 let separating otf only a small portion of the cell. Expanse 38 mm. 



One specimen from Tyron, North Carolina (Fiske). 



Readily known by its very broad and heavy body ; allied to C. 

 rufilabris, but separated from it and allies by shorter cubital cell, 

 more gradate veins, flatter vertex, etc., as well as by heavy body. 



Clirysopa fascialis n. sp. — Head pale greenish white, two dark dots 

 under each eye in a liue toward mouth ; palpi and antenna; wholly pale; thorax 

 and abdomen entirely green and unmarked ; legs pale greenish ; wings hyaline, 

 venation green, basal costal cross-veinlets and some of the anal cross-veinlets 

 wholly black, other cross-veinlets black at bases, gradate veinlets marked with 

 black in middle, divisory veinlet of third cubital cell wholly green ; hindwings 

 with venation colored similar to forewings, pterostigma not distinct in either 

 pair. Wings moderately long, both pairs acute at tips; antenuse not as long as 

 wings. Length 16 mm. 



One specimen from Durango, Mexico. 



Lencochrysa auteiinata n. sp. — Head pale yellowish, vertex with two 

 reddish stripes above, and an angulate red line in front over bases of antennae; 

 antennae pale, basal joint with two reddish lines above. 8 or 10 of the next joints 

 have a continuous red stripe on inner side; prouotum pale, an indistinct dark 

 mark each side, rest of thorax pale; abdomen brown above, pale below; legs
