NATHAN BANKS. 343 



Chrysopa luctuosa n. sp. 



Green, heavily marked with black ; antennae, including the second 

 joint, wholly pale yellowish ; face with a large shining black inter- 

 antennal mark, spreading out below to the eyes, and above in a V- 

 mark on the vertex ; a black streak under each eye. Pronotum very 

 short and broad, sides parallel, rounded in front, a broad submedian 

 black stripe each side continued back on anterior part of the meso- 

 thorax ; a transverse mark on the mesopleura, and a spot and angular 

 mark below on the metapleura, black ; abdomen dark green, marked 

 with black each side. Wings with nearly all veins black, the subcosta, 

 the median and the cubitus for one-fourth the way out are black, the 

 radius wholly green ; the radial sector black, the costals, gradates, anal 

 veins, divisory veinlet, branches of radial sector, and marginal forks 

 black, the gradates margined with brown, the stigma distinct and long. 

 Wings moderately broad, hardly acute at tips, second cubital much 

 shorter than the third, the divisory veinlet ending beyond the cross- 

 vein, inner gradate series (ot four veinlets) nearer to the outer series 

 than to the radial sector. 



Expanse 24 mill. 



From Ft. Wingate, New Mexico, 26 June (Woodgate col- 

 lection); goes in the group of sclnvarzi. 



Chrysopa gravida n. sp. 



Yellowish (greenish in life?); antennae wholly pale, a large shining 

 black interantennal mark spread out below to reach the eyes and 

 above, the sockets are margined to the eyes ; no marks on cheeks nor 

 vertex; palpi marked with dark. Pronotum broad and rather long, 

 and very much narrowed in front, with very broad, dark brown stripe 

 on each side from margin nearly one-half way to middle. A brown dot 

 on lateral lobes of meso- and metathorax. Abdomen and legs pale, 

 wings with pale venation, but most of the cross-veins, base of median 

 to beyond third cell, base of radial sector and the anals brownish ; 

 stigma indistinct; hind wings less heavily marked. Wings large and 

 broad, tip rounded, second cubital cell as long as the third, latter 

 wider at tip, divisory veinlet ends much beyond the cross-vein ; inner 

 gradate series (eight in number) much nearer the outer than to the 

 radial sector ; in hind wings the radial sector and median united only 

 for a short distance. 



Expanse 36 mm. 



From Yosemite, California ; a large and heavy species 

 related to Ch. robusta of North Carolina, but the interantennal 

 mark distinguishes it from that species.
