AMERICAN NEUROPTERA. 155 



One specimen from East Las Vegas, New Mexico (Cockerell). 

 Separated from allied forms by the black (instead of red) stripe 

 under eyes, and the wholly black costal cross-veinlets. 



Chrysopa arizonensi* n. sp. — Face pale yellowish ; a black dash below 

 each eye extending toward mouth, inward of this and below each antennae is a 

 red dot, above base of antennae is a transverse, angular, red line extending from 

 eye to eye, its angle projecting between bases of antennae; palpi mostly red- 

 brown; antennae pale. Pronotum pale, a narrow dark line on front of extreme 

 side margins; rest of thorax and the legs pale. Abdomen pale, when fresh pos- 

 sibly marked with dark at bases of segments. Wings hyaline ; veins green ; the 

 gradate veinlets, several basal veinlets, and parts of some of the other cross-vein- 

 lets are brown; in hind wings only a few veinlets brown. Pterostigma moder- 

 ately distinct. Antennae quite short; prothorax short, narrowed in front; wings 

 of moderate width, pointed at tips, divisory veinlet of third cubital cell ending 

 much beyond the first cross-veinlet from the radial sector. Length 12 mm. 



One specimen from Yuma, Arizona (Morse, collector). Very 

 easily separated from all our other species of the genus by the angu- 

 lar red line on head ; a somewhat similar mark is in Leucochri/stt 

 americana. 



Chrysopa plora lunula Fitch. — Pale greenish or yellowish, in life 

 showing a paler median, dorsal stripe, often fading out in dry specimens. A 

 straight brown mark under each eye, and sometimes a brown dot at each outer 

 anterior corner of the pronotum. Venation pale green or yellowish ; pterostigma 

 rather distinct. Pronotum short and broad, as broad as long, sides parallel, not 

 narrowed in front. Wings quite broad: anterior pair rounded at tip, hind wings 

 slightly acute ; divisory veinlet of third cubital usually ends on or just beyond 

 the cross-veinlet. Length 14-15 mm. 



Specimens have been seen from Columbus, Ohio, March ; Agri- 

 cultural College, Mich, Febr. ; Boulder, Colo., Aug.; and Austin, 

 Texas, March ; also from Utica, Miss. ; Ames, Iowa ; and Luverne, 

 Minn. Fitch records it from Northern Illinois and New York. 

 The Michigan specimens had passed the winter in dead leaves and 

 in hedges. Shimer, under the name of Ch. illinoiensis, has given :i 

 long account of its life history. 



CHrysopa liarrisii Fitch. — Pale green throughout in life, fading to yel- 

 low in dried specimens: a pale yellowish median, dorsal stripe. Cheeks suffused 

 with reddish ; sometimes a minute red dot on vertex near each eye. Venation 

 green, pterostigma quite distinct. Antennae moderately long; pronotum about 

 as broad as long, sides parallel, not narrowed in front. Wings slender, acute ;it 

 tips ; divisory veinlet of third cubital usually ends beyond the cross-veinlet. 

 Length 13-15 mm. 



Specimens are before me from Washington, D. C, from pine trees 



in July; Manchester, New Jersey, Sept. ; Staten Island, New York,
