NEUROPTEROID INSECTS FROM SZECHWAN — BANKS 187 



1. Costal area extremely broad from the very base Ankylopteryx 



Costal area at first very narrow, then gradually widening 2 



2. Hind tibia not more than three times as long as hind tarsus ; 



third cubital cell divided longitudinally Nothochrysa 



Hind tibia more than three times as long as hind tarsus 3 



3. Cubitus of forewing running out to apical fifth of wing; cubital 



area broader than the postcubital area Prochrysopa 



Cubitus bends down to hind margin before apical third of wing 4 



4. Third cubital cell longitudinally divided Leucochrysa 



Third cubital cell obliquely divided, the vein ending on upper 



margin of cell 5 



5. But two rows of gradate veinlets Chrysopa 



More than two rows, or irregular 6 



6. Cross veins many, and not in rows Tiimeochrysa 



Cross veins in three rows Chrysopidia 



Chrysoflecta Navas, 1910, is the same as Tmneoclvnjsa Needham, 

 1909. 



Cintameva Navas was made for species having cross veins in the 

 costal area of stigma; this character is somewhat variable; but the 

 group includes G. perla Linnaeus, which is the type of Chrysopa^ so 

 falls. 



Nineta Navas was made for Chrysopa vittata^ on account of the 

 rather more prominent cerci in the male ; this is also a variable char- 

 acter. The type species in the hinclwing has the radial sector separate 

 from the median near base, tho very close; other species placed in 

 Nineta have them partly united ; at best it is a subgenus. 



Genus NOTHOCHRYSA McLachlan 



NOTHOCHRYSA AEQUALIS Walker 



Three from Suifu, 1,000 to 2,000 feet. 



Genus ANKYLOPTERYX Brauer 



ANKYLOPTERYX 8-PUNCTATA Fabricius 



One from Beh Luh Din, September 20-28, 6,000 feet. 

 Genus CHRYSOPIDIA Navas 



CHRYSOPIDIA REGULATA Navas 



Plate 27, Figure 17 



Two from near Washan, July 26, 6,000 feet, and Shih Men Kan, 

 Kweichow, July 28. 



The discoidal cell is small, but the vein ends plainly beyond the 

 cross vein, eight or nine cubitals beyond; stigma with cross veins in 

 costal area ; post cubital space scarcely broader than costal, but about 

 twice as wide as the cubital area; costals and gradates, and a few 

 other cross veins more or less plainly black ; inner gradates extended 

 basally; only three or four free intermediates. Navas described it 

 from Yunnan.
