154 NATHAN BANKS. 



Chrysopa emuiicta Fitch.— Pale yellowish green, abdomen darker green; 

 a reddish spot under each eye extending toward the mouth ; palpi marked with 

 black. Wings with green veins, the gradate series black, and the ends of many 

 other cross-veinlets also black ; pterostigma quite distinct. Wings large and 

 broad, the costal area broad, tips rounded in fore wings, in hind pair more acute ; 

 the divisory veinlet of the third cubital cell ends much beyond the cross-veinlet ; 

 there are eight to ten veinlets in the gradate series. Length 19 mm. 



Fitch described this species from Central New York. I have 

 seen but one specimen which fits his description, it is from Franco- 

 nia, N. H. (Slosson). It is evidently an uncommon northern spe- 

 cies, and one of the largest in the genus. 



C'hrjsopa erj throcephala Banks.— Pale yellowish green, abdomen 

 darker green ; a black spot each side near base of clypeus. Wings with green 

 veins; gradate veinlets black ; the costal and radial cross-veinlets are black in 

 the middle, green at ends; pterostigma not distinct. Antennae short; pronotum 

 narrowed in front, rather short. Wings quite long and broad, barely acute at 

 tips; gradate series of seven to nine veinlets; the divisory veinlet of third cubital 

 cell ends just beyond the cross-veinlet ; costal area not very broad. Length 18- 

 20 mm. 



Specimens come from San Bernardino, Calif, July ; Mesilla, N. 

 Mex., July 18th ; and Pullman, Wash., July 3rd. It is easily dis- 

 tinguished by its large size, and by the costal and radial cross-vein- 

 lets being black in the middle, a peculiarity not found in any of our 

 other species. 



Clirysopa medialis n. sp. — Face pale yellow, with a red stripe from each 

 eye to mouth, a red dot above and adjoining'each eye, sometimes a transverse red 

 mark across vertex; pronotum green, red on anterior margin, and a median red 

 stripe from end to end ; middle portions of meso- and metathorax marked with 

 ied, sides yellowish green ; abdomen pale green, with a median red stripe from 

 base to tip, widened on the posterior margin of each segment; legs pale green. 

 Wings with green venation, considerably marked with black ; the gradate series 

 and about all of the other cross-veinlets are black at the ends. Antennae rather 

 short; wings plainly acute at tips; the divisory veinlet of the third cubital cell 

 ends slightly beyond the cross-vein. Length 15 mm. 



A few specimens were beaten from hickory foliage at High Island, 

 near the District of Columbia, in the latter part of September. In 

 life the red markings are very prominent, and the insect at once 

 reminds one of Ch. quadripunctata, but the arrangement of the 

 markings is very different. 



Chrysopa cockerelli n. sp. — Face yellowish, a black stripe from each 

 eye to the mouth, connecting with each other. Antenna pale yellow ; pronotum 

 and thorax green, the latter with a slight reddish color on each anterior lobe; 

 abdomen and legs green ; wings with green veins, the cross-veinlets nearly all 

 black in part; the costal cross-veinlets wholly black. Antennas short, wings 

 moderately broad, scarcely acute at tips; divisory veinlet of third cubital cell 

 ends beyond cross-veinlet. Abdomen very short. Length 15 mm.
