extreme tarsal joints and the claws a little darker. The claws broad 

 at the base and strongly hooked. Wings hyaline with yellowish 

 nervations (greenish in life); the nervures strongly haired. Ptero- 

 stigma long, yellowish green, very conspicuous, especially in the hind 

 wings. The number of gradate veins in the inner row in the fore 

 wing 5 (rarely 4 or 6) and in the outer row 6 (scarcely 5 or 7); in 

 the hind wing 4/5; scarcely 5/6. Number of cross veins in. the costal 

 area of fore wings before the pterostigma 15 — 17; in the area be- 

 tween radius and its sector 9 — 10. 



Length of body 7 — 9 mm; fore wing 11 mm; hind wing 9,5 mm; 

 antennae 14 mm. 



At first sight one may take the species for Chrysopa flaveola Sehn.; 

 but its comparatively broader wings, its paler antennae and the 

 unspotted basal Joint of antennae make the species easely recognizable. 



In the collection of S auter there is a long series of specimens 

 from Sokutso, V. 1912; Taihorin. 7. VII. 1911 and Anping, 7. VII.

 part, becoming darker in the apical one. Abdomen brownish yellow 

 (in life yellowish green). Legs pale with a very feeble brownish or 

 yellowish tinge. The knees, the apices of the tibiae, of the tarsal joints 

 and the claws a little darker. Wings hyaline; pterostigma distinctly 

 marked, but not strongly. All nervures and borders haired. The 

 longitudinal nervures in both pairs of wings yellowish (greenish yellow 

 in life) with exception of the base of the radial sector and its branches, 

 which are brownish black. In the fore wings the cross veins in the 

 costal area and the gradate veins are always totally blackish brown 

 or black; the other cross veins totally brownish black in their füll
