CHRYSOPIDIA FUSCATA Navas 



Plate 27, Figx^tse 10 



Very similar to regulata., but the proiiotum is slenderer and nar- 

 rowed in front; the inner gradates are not extended basally and not 

 parallel to other rows ; there may be six gradates in the middle row ; 

 the divisory cell small; the costal area broader than in regulata; on 

 the outer side of the basal joint of the antennae is a more or less dis- 

 tinct reddish mark; eight or nine cubitals beyond the divisory cell; 

 stigmal area with many cross veins in the costal space, five or six 

 in the subcostal; palpi partly dark; six or seven free intermediates. 



One from Chengtu, December 21, 1,700 feet; one from Beh Luh 

 Din, July 23, 6,000 feet; and one from Mount Omei, July 10-15, 

 4,000-6,000 feet. The last specimen has a reddish mark across each 

 side of face, the divisory ends at the cross vein. 



Genus CHRYSOPA Leach 



The species of Chrysopa from western China known to me are 

 separable as follows: 



1. A dark spot under each antenua 2 



No dark spot under each antenna 6 



2. These spots connected up to those on vertex to form an X furcifera 



These spots not so connected S 



3. Two spots on vertex and one between antennae 4 



No spots on vertex o 



4. Most costal cross veins dark; stigmal costal area not cross- 



veined bicristata 



Only a few costals near base dark ; stigmal costal area with cross 

 veins kreyembergi 



5. A spot below outer side of each antenna, one on each cheek, and 



one each side on clypeus, thus three spots close together on 



each side of face; palpi partly dark illota 



A spot below each antenna, and one on each side of the clypeus, 



none on cheeks; palpi pale; stigma veined cognata 



6. In forewing a dark spot covering the end branches of anal 



vein; palpi pale, no marks on head; stigmal costal area 



veined 7 



No such spot on forewing 8 



7. Some costal cross veins near base are partly black; few costal 



cells three times as long as broad ; hairs on veins moderately 



long chione 



Costal cross veins wholly green, very numerous, and many cells 



fully four times as long as broad ; hairs on veins very long grahami 



8. Branches of anal vein partly dark ; divisory veinlet ends beyond 



cross vein; a dark spot on cheek 9 



Branches of anals pale, divisory rarely ends beyond cross vein 10 



9. Palpi pale; stigmal costal area not veined; sides of pronotum 



without reddish kiansuensis 



Palpi dark ; stigmal costal area with many cross veins ; sides of 

 pronotum reddish alethes
