158 NATHAN BANKS. 



Meleoma innovata Hagen. — Pale green ; a pale yellowish dorsal, median 

 stripe ; a red-brown stripe -from each eye to mouth; palpi marked with reddish. 

 In male the lower part of face is gibbous, a cavity above it marked with pink ; 

 between bases of antennse a small tubercle, bifid at tip and curved downward. 

 Basal joints of antennae divergent, and swollen near tip, especially below, beyond 

 simple. Female without these structural modifications, but the basal joints are 

 widely separate at base, and much more slender than in any Chrysopa. Wings 

 rather long and slender, anterior pair rounded at tip, hind pair acute at tip. 

 Venation green, some cross-veinlets marked in part with black ; pterostigma 

 quite distinct. Pronotum broader than long, not narrowed in front. Length 

 18-20 mm. 



I have a pair ; male from Amecameca, Mexico, the female from 

 Santa Fe, New Mexico, July. At the time of my description of 

 M. mexieana, which was based on the former specimen, I had not 

 examined Hagen's description of Ch. innovata carefully. It is 

 strange that Hagen did not place this species in Meleoma, since he 

 states that it possesses the very character upon which this genus was 

 based. 



EREMOCHRYSA new gen. 



Characters in general those of Chrysopa, but there is but one 

 (the outer) series of gradate veinlets in hind wings; the branches 

 from the radial sector being curved and sinuate. In the forewings 

 the inner row of gradate veinlets are only three or four in number. 

 The wings are narrower than in most species of Chrysopa; the longi- 

 tudinal veins are usually marked with brown, and there is usually a 

 brown dot under the tip of each femur. Type Ch. punctinervis 

 McLach. 



Three species can be referred to this genus, and they may be re- 

 cognized from the following table : 



1. Longitudinal veins marked with brown 2. 



Longitudinal veins not marked with brown, cross-veinlets almost wholly 



brown hageni, 



2. Transverse veinlets wholly brown, larger species fraterna . 



Transverse veinlets interruptedly brown and pale, smaller species. 



puiicliiiervis. 



Eremoclirysa liageni n. sp. — Head pale greenish yellow, a black stripe 

 on each cheek reaching to mouth, second joint of antenna? blackish, first joint 

 above red-brown, beyond pale, rather darker towards tips. A black spot between 

 antenna? extending backward in the shape of a Y, its posterior tips enlarged. 

 Palpi red-brown, pale on base. Pronotum pale, a median narrow line, and some 

 spots each side dark ; rest of thorax and the legs pale Abdomen pale, evidently 

 with various dark marks when fresb, most of the fourth and the sixth and sev- 

 enth segments red-brown above. Wings hyaline, veins mostly pale, cross-vein- 

 lets mostly dark, except those of the costal area which are dark only at subcostal
