344 NEUROPTERA. 



Chrysopa uanina n. sp. 



Yellowish (probably greenish in life); a black mark each side on 

 clypeus, an oblique blackish line under each antenna, uniting in the 

 middle, a black line above antennal sockets from eye to eye, and angu- 

 late in the middle ; palpi marked with black ; antennae pale on joints 

 one and two, then black for about one-third the waj^ to tip, thence 

 pale. Pronotum with a broad blackish streak on each side reaching 

 to margin, the mesonotum with two dark spots each side in front ; 

 abdomen and legs pale. Wings hyaline, the costa and median vein 

 black at base, and the anal and its branches almost entirely black ; 

 the cubitus is rather darker on base than elsewhere ; many of the cross- 

 veins wholly black, branches of radial sector black, stigma distinct. 

 Pronotum broader than long, much narrowed in front. Wings very 

 long, hardly acute at tips ; second cubital cell very slender, third barely 

 widened at tip, the divisory veinlet ending much beyond the cross- 

 vein, about ten or eleven gradates in outer series, about six in inner 

 series, the inner series much nearer to the outer series than to the 

 radial sector. 



Expanse 37 mm. 



From Palmerlee, Arizona (Biederman). 



Our species of Chrysopa, with the longitudinal veins partly 

 black at base, may be separated as follows ; all have the 

 antennal sockets margined above and below with black : 



1. Pronotum broadly margined with black 2 



Pronotum with two black stripes, remote from the margin ; sub- 



costa black at base luctuosa. 



2. Basal part of antennte beyond the second joint black ; subcosta not 



black naiiiua. 



Antennae pale 3. 



3. Subcosta black ; a black mark on each cheek scliwarzi. 



Subcosta not dark, median, costa and anal only dark ; no mark on 



cheeks gravida. 



CHRYSOPIELLA n. gen. 



Differs from Chrysopa in having but one series of gradate 

 veins in either wing, this is the outer series ; the median cells 

 are consequently very long and curved. The radius beyond 

 the end of the subcosta is connected to the costal margin by 

 about four veinlets, the divisory cell is similar to that of 

 Chrysopa ; the antennae are close together at base. The two 

 species are greenish ; not brownish as in Eremochrysa, which 

 has only one series of gradate veinlets in the hind wings.
