Psyche 
[June 
antenna; there is no cheek mark, nor any spots on the clypeus; 
palpi wholly pale green. Antennae entirely pale greenish, no marks 
on basal nor second joint; in one specimen the vertex is faintly 
yellowish in front; the snb triangular elevated area is rather smaller 
than usual, the groove between it and the eye being quite broad. 
Pronotum nearly twice as broad as long, sides parallel, but in 
front narrowed at the head. Legs short, pale, unmarked. Abdomen 
of female about as long as usual, in male not reaching half way to 
tip of wings, its tip rounded. The hairs on abdomen (and pronotum) 
are wholly white. 
The wings of male are almost acute at tip, but more rounded in 
female. The venation is the usual Chrysopa type; the sub-costal 
cross-veins at stigma weak and few. Sixteen costals before stigma, 
eight radials; costal area only a little more than one-half the width 
of the radial area; marginal area much broader than cubital; di- 
visorv vein ends beyond the cross-vein above, but five cubital cross- 
veins beyond; three or four outer gradates, and one inner, about the 
same in hind wing. The third cubital cell has two branches to the 
hind margin, and the next cell beyond but one branch (as normal 
Chrysopa ). 
The costal fringe is quite long, but not dense, the hairs on the 
veins are long, but not numerous. Length of fore wing, 8.5 mm.; 
width, 2.8 mm. 
Male and female from Ft. Yuma, California, 6 June, 13 June, 
Andahl collector, from G. H. and J. L. Sperry. 
This insect has no near relation to the plorabunda section of 
Chrysopa, which are almost wholly green. It has no sinuous costal 
cross-veins found in that section. The venation is more open than 
the usual Chrysopa . In the male the apical part of wing is more 
narrow and there are but three branches of the radial sector that 
reach the outer margin of wing. 
Type: M. C. Z. no. 28346. 
Chrysopa elariveita sp. nov. 
Pale; no marks on face nor cheek; basal antennal joint unmarked, 
second joint black, beyond faintly darkened; basal joint rather 
short and broad at base, little separated from each other, palpi pale, 
last joint darkened. Vertex with a red mark each side by eye, 
middle area elevated.
