150 NATHAN BANKS. 



Specimens have been seen from Buffalo, Ithaca, Staten Island and 

 Sea Cliff, N. Y. ; Washington, D. C. ; Falls Church, Va. ; Colum- 

 bus, Ohio ; Onaga, Kans. ; Ft. Collins, Colo., and Sherbrooke, Can. ; 

 also from Mass. and R. I. They appear from June till September, 

 but apparently most common in June. Specimens vary in markings 

 of veins; sometimes many cross-veins are black only in middle. It 

 has been taken at electric lights. 



Clirysopa lateralis Guerin. — Face pale yellowish, faint trace of red spot 

 each side near clypeus, vertex green, bordered in front just above antenna? with 

 reddish, basal joint of autennas marked with reddish on outer and upper side, 

 beyoud for about one-fourth length black. Pronotum green, with a red stripe on 

 each side, rest of thorax and abdomen green ; legs paler. Wings with green ven- 

 ation, the gradate series, costals for about one-half the distance, and most of rad- 

 ial cross- vein lets black ; many other cross-veinlets partly black ; pterostigma not 

 prominent. Antennae reaching to tip of wings; pronotum much narrowed in 

 front, trans verse groove very distinct. Wings long and narrow, acute at tips ; 

 the inner gradate series more or less incomplete. Length 15 mm. 



It was described from Mexico. Hagen described Ch. pavida from 

 Mexico and South Carolina. I have seen specimens from South 

 Carolina and from Runnymede and Key West, Florida. The latter 

 was bred from a white cocoon covered with bits of bark and debris. 

 A specimen from Jalapa, Mexico, appears to be the same species, 

 but the red mark on the basal antenna] joint is very dark, and the 

 cross-veinlets are more black. 



Chrysopa Columbiana n. sp. — Head pale yellowish, without markings, 

 thorax and abdomen pale green, second joint of antennas and beyond for about 

 one-fourth length black. Wings with green venation, gradate series and radial 

 cross-veinlets black, many other cross-veinlets black in part, very few black vein- 

 lets in hind wings ; pterostigma very distinct in both wings, pale brown in color. 

 Pronotum broad, very little narrowed in front, transverse groove not distinct. 

 Wings quite narrow, acute at tips. Length 13 mm. 



One specimen from Washington, D. C. Related to Ch. nigricor- 

 nis, but the unmarked face and the black radial cross veinlets lead 

 me to consider it distinct. 



Clirysopa lineaticornis Fitch.— Face almost white; vertex pale green ; 

 palpi white; basal joints of antennae whitish, with a prominent black stripe on 

 outer upper side, basal third of antennas beyond black. Prothorax pale green, 

 sometimes with a little reddish on outer edge; no yellowish stripe in middle; 

 rest of thorax and the abdomen dull green, the latter more yellowish near tip ; 

 legs whitish ; wings whitish green, green venation, gradate veinlets, costals, and 

 often the radial cross-veinlets black ; many other cross-veinlets more or less black ; 

 pterostigma quite distinct. Hind wings with costals browu, the pterostigma also
