Genus Eremochrysa 
This genus is represented in the western part of our country by 
many species. All have the cross-veins more or less darkened, and 
often the longitudinal veins dotted. As a rule the wings are less 
widened apically than in Chrysopa, and the tips more rounded. In 
Chrysopa the branches of the radial sector which reach the outer 
wing-marking are forked beyond the outer gradates, in Eremochrysa 
rarely more than one is forked beyond the outer gradates. 
The males have an extension at the lower end of the abdomen, 
not present in Chrysopa j in one group this process is upcurved, and 
with simple hairs, in the other group the process is straight and pro- 
vided with reclinate hairs or bristles. 
Table of Species of Eremochrysa 
1. Front and mid tibiae with a dark cross-band about one-third 
way from base, often also a dark spot at base of these tibiae; 
venation mostly dotted, vertex usually with reddish lines or 
spots tibialis sp. nov. 
Front and mid tibiae without dark band 2 
2. Antennae just beyond second joint with several joints black or 
with a black band; face with a reddish stain under bases of 
antennae rufina sp. nov. 
Antennae beyond second joint not at all black 3 
3. Veins and many of the cross-veins dotted with dark 4 
Veins not dotted, cross-veins mostly entirely dark 5 
4. Face often with yellowish or reddish marks (sometimes 
united) vertex with reddish lines or spots; fore wings rather 
broad so that four or five of the branches of radial sector reach 
the outer margin punctinervis McLach. 
Face usually without marks, vertex mostly rufous, at least in 
front, and few if any lines or spots; the apical part of wing 
more narrow so that only two or three branches of radial 
sector reach outer margin pumilis sp. nov. 
5. Four or five branches of radial sector reach margin; usually 
black or dark marks on face and vertex, and three stripes on 
the basal joints of antennae, and three on pronotum. 
fraterna Bks. 
But two or three branches of radial sector reach outer margin. 
Not so heavily marked, few marks on face or pronotum 6
