NATHAN BANKS. 341 



narrowed at tip, the third very broad at tip, divisory veinlet ends 

 beyond cross-vein, inner gradate series (six to eight veins) as near to 

 radial sector as to the outer row ; in hind wings the radial sector unites 

 with the median for nearly a cell length. 

 Expanse 27 to 29 mm. 



From- Beaufort. North Carolina, 15 May (Woglum), and 

 Raleigh, North Carolina, 15 July (Sherman). Differs from 

 Ch. oculata in clypeal marks and less marked antennal sockets. 



Chrysopa separata n. sp. 



Close to Ch. oculata and Ch. chlorophana, but differs by the narrow 

 straight mark on the cheeks that is not connected, nor bent up to the 

 antennal mark ; there is much red on the clypeus in form of a spot 

 each side ; there are no marks on the vertex ; the basal joint of the 

 antennae is more or less red above ; the anterior narrowed part of the 

 pronotum is black on the edge. The wings have pale venation, the 

 costals black at ends, the base of the second cubital cell and the two 

 cross-veins behind it are black ; in the hind wings the costals are dark. 

 Wings hardly broad, the second cubital plainly longer than the third, 

 latter broad at tip, the divisory ends beyond the cross-vein ; the inner 

 gradate series (of seven to nine veins) is much nearer to ttie outer row 

 than to the radial sector. 



Expanse 23-26 mm. 



From Chimney Gulch, Golden, Colorado (Oslar), and 

 Pecos, New^ Mexico, 23 June (Cockerell). 



Some specimens show black at bases of branches of the 

 radial sector, and radial cross-veins. 



Chrysopa pleiiralis n. sp. 



Green ; second joint of antennae black, basal joint reddish ; face 

 marked as in Ch. oculata, the marks over the antennal sockets con- 

 tinued back on the vertex, a posterior transverse black line on vertex 

 (not seen in Ch. oculata); pronotum very broad, sides parallel, anterior 

 margin rounded, with an interrupted black line near each outer side, 

 and indistinct black spots within ; rest of the thorax unmarked above, 

 but the pleuras have a black line under each wing to the base of the legs 

 and a few transverse lines as shown in the figure ; abdomen dark green- 

 ish ; legs pale. Wings with green venation, and distinct green stigma, 

 the costals black at each end, and many other cross-veins black in part, 

 the gradates mostly dark, also the bases of the branches of radial sector; 

 in hind wings the gradates are pale, and costals wholly black. Wings 

 moderately broad, broadly rounded at tips ; second cubital cell rather 

 larger than the third, divisory veinlet ending much beyond the cross- 

 vein ; inner gradate series as near to radial sector as to outer series ;
