190 PROCEEDINGS OF THE NATIONAL MUSEUM vol.88 



Forewings, 15 to 17 mm. long; 5.5 to 6.3 mm. wide. 



From Beh Liih Din, July 27-31, 6,000 feet (holotype), and Mount 

 Omei, July, 11,000 feet, both Szechwan. Probably similar to C. dasy- 

 phlehia McLaclilan, but that species has no black spots. Holotype, 

 U. S. N. M. No. 53149. Paratype in M. C. Z. 



CHRYSOPA FRATERCULA, nev/ species 



Head pale, a dark mark under each eye, and one on lateral edge 

 of clypeus; palpi lightly marked with dark lines; antennae pale; 

 thorax, legs, and abdomen pale. Forewings with pale greenish vena- 

 tion, the gradates dark, many other cross veins dark at one end, the 

 costals at the subcosta, the radials at each end, the branches of radial 

 sector at the sector, and a few other cross veins toward base are partly 

 or wholly dark; stigma not very distinct. In hindwings some of 

 the costals and radials dark at one end, and the gradates partly or 

 wholly dark. 



Wings of moderate width, acute at tip of hmd pair, hairs rather 

 short. 



In forewing the divisory ends beyond the cross vein, six cubitals 

 beyond it ; postcubital area not twice as broad as the cubital, but about 

 as broad as the costal area ; stigmal costal area without cross veins, 

 about four in subcostal part; gradates about seven in inner and 

 eight in outer row, parallel, in each row each veinlet is well separated 

 from the next (but not nearly so much so as in O. sinica.) In hind- 

 wing five gradates in inner row and seven in outer, rows parallel ; the 

 triangle between the radial sector and the median is of moderate size. 



Length of forewing, 13 mm.; width, 4.5 mm. 



One from Shin Kai Si, Mount Omei, July 1-17. Holotype, 

 U. S. N. M. No. 53150. 



Probably related to C. sinica^ but in that species the gradates are 

 fewer and more separated from one another, the divisory ends before 

 the cross vein, the palpi more dark, the pronotum less long, and often 

 reddish marks on head and thorax. 



CHRYSOPA KIANSUENSIS Navas 



Specimens from Chengtu, 1,700 feet. May 1, May 25, July 13 ; Shin 

 Kai Si, Mount Omei 6,000 feet and 11,000 feet; Hong Chuen Pin, 

 Mount Omei, August 27, 5,500 feet. One from Chengtu is the size 

 of type and has five gradates in each row, but most of the others are 

 somewhat larger and have one or two more veinlets in each gradate 

 series. There are seven cubitals beyond the divisory veinlet, the 

 postcubital area is hardly one fourth broader than the cubital area; 

 the stigmal costal area is without cross vein, but with two to four 

 in the subcostal part.
