I^EUROPTEROID INSECTS FROM SZECHWAN — BANKS 189 



10. No spots on face; veins wholly pale, palpi pale carnea 



A dark spot on each cheek, and often on sides of clypens 11 



11. Divisory ends at or before cross vein ; gradates in each row 



widely separated; palpi partly dark sinica 



Divisory ends much beyond cross vein ; gradates less separated 



from each other fratercula 



CHRYSOPA GRAHAMI, new species 

 Plate 27, Figures 7, 13 



Head and body pale, unmarked, antennae and palpi pale; wings 

 with greenish venation; stigma rather dark, long, the costal part 

 broad and with many cross veins, subcostal part with two or three 

 cross veins ; inner gradates dark ; a black spot over the ends of the first 

 anal vein and its connection to the cubitus; in hindwings all veins 

 pale, but the inner gradates may be a little darker. 



Wings broad, apex of hind pair acute, hairs on veins very long. 

 Forewing with the divisory veinlet ending beyond the cross vein, 

 eight or nine cubitals beyond it; inner gradates point toward the 

 stigma, not extended basally, outer gradates parallel to outer margin, 

 about 10 in each row, and in the row rather close to each other ; radial 

 sector moderately curved; costal space at widest almost equal to the 

 postcubital area, latter from two and a half to three times as broad as 

 the cubital area; the costals are very numerous, fully 30 before the 

 stigma, and many of the cells are more than four times as long as 

 broad; about 16 radial cross veins. In hindwing the gradates are 

 about eight in each row, not parallel ; the triangle between radial sec- 

 tor and median vein near base is larger than usual. 



Forewing, 19 to 20 mm. long; 7 to 7.5 mm. wide. 



Three specimens from near Washan, Szechwan, July 26, 6,000 feet. 

 Holotype, U. S. N. M. No. 53148. Paratypes in U. S. N. M. and M. C. Z. 



CHRYSOPA CHIONE, new species 

 Plate 27, Figuke 12 



Similar to C. grahami^ not quite so large, but with the same black 

 spot over the anals as in that species, also there are no marks on head 

 or body, and antennae and palpi are pale ; the stigma is also like that 

 species, and the divisory veinlet, and eight or nine cubitals beyond as 

 in grahami. 



The forewings have the costal area much less broad and the costals 

 fewer, so that no costal cell is over three times as broad as long, and 

 6 to 10 of the costals toward base of the wing are partly black on outer 

 half; the inner gradates are dark, also sometimes the base of the radial 

 sector, otherwise tlie veins are pale. 



In hindwing all the veins are pale, except sometimes the costals are 

 partly dark. In the forewing the post cubital area is about two to two 

 and a half times as broad as the cubital area.
