AMERICAN NEUROPTKKA. 151 



distinct. Antennae reach almost to tip of wings, the basal joints rather larger 

 than usual ; prothorax plainly narrowed in front, the transverse furrow is not 

 very distinct. Wings quite narrow, acute at tips. Length 13-15 mm. 



It \v;is described from Central New York. I have seen specimens 

 from Franconia, New Hampshire; Agricultural College, Michigan, 

 July 12th; Bay Ridge, Maryland, July; Washington, D. C, July 

 16th, on pine; and Brookline, Mass. This may he the same as Ch. 

 ampla Walk., from Georgia, but I am not certain. 



Ckrysopa coloradensis Banks.— Face pale green, a red-brown crescent 

 under each antennae, a red-brown stripe under each eye (not reaching to mouth), 

 and vertex with a reddish mark each side adjoining the eye ; palpi marked with 

 red; basal joint of antennae pale, second and beyond for about one-fourth the 

 length, black. Prothorax green, with a red stripe on each side; anterior lobes 

 of mesothorax reddish; legs pale; abdomen darker green. Wings with green 

 venation ; gradate series, the costals and the radials entirely, and the other cross- 

 veinlets partly black ; pterostigma rather distinct. Antennae not very long; pro- 

 notum broader than long, narrowed in front; wings moderately long, scarcely 

 acute at tip, except in the hind pair; divisory veinlet of third cubital cell end- 

 ing much beyond cross-vein. Length 14-17 mm. 



I have seen specimens from Denver, Colo. ; Mesilla and Santa Fe, 

 New Mexico, July; Williams, Arizona, July ; Hood River, Oregon, 

 Sept.; Gazelle, Calif, Sept., and Pullman, Washington. It is a 

 very handsome species and not very closely related to any other form. 



t'hrysopa sabulosa Banks.— Face yellowish, a triangular black spot 

 under each eye, a black spot under each antenna (but separated therefrom), and 

 a black dot above each antenna. Basal joint of antenna broadly marked with 

 black in front and on outer side, second joint black and the following ones also 

 to about one-fourth the length of antenna. Palpi marked with black. Thorax, 

 abdomen and legs green, unmarked. Wings with green venation, pterostigma 

 rather distinct. The antennae are rather short; the pronotum about twice as 

 broad as long; abdomen short ; wings rounded at tips, usually but one series (the 

 outer) of gradate veins, sometimes there are traces of the inner series. There 

 are not as many hairs on the veins as in most species. The divisory veinlet of 

 the third cubital cell ends beyond the cross-vein. The male genitalia is quite 

 elaborate, the lower part ends in three tufts of black bristles. Length 12-14 mm. 



The type is from Colorado, and I have another specimen from 

 Southwestern Colorado, July 12th (Oslar). There is a male in the 

 National Museum collection from Las Cruces, N. Mex. (Cockerell). 

 It is a very peculiar species on account of the almost complete 

 absence of the inner series of gradate veinlets in both wing's. 



Chrysopa explorata Hagen. — " Yellowish ; face with a large, quadrang- 

 ular spot, occiput with a Y-shaped streak and spot, red ; antennae yellowish ; fus-
