evidences which compel us to regard these minute and seemingly 
unimportant marks as valid indications of differences which ac¬ 
tually exist in nature. 
To facilitate the discrimination of these species of this genus 
which are here described, they are arranged in an analytical 
series, which, on a slight inspection, will be intelligible to every 
reader.' 
1. (18.) Sockets in which the antennse are inserted margined 
more or less with black. • 
2. (5.) Two black or dusky stripes upon the top of the head. 
3. (4.) Veinlets mostly black, a few with a short green band 
on their middle. 
The White-horned Golden-eye (Chrysopa albicornis ). Antennse whitish, 
basal joint with an orange-red ring surrounding it wholly or in part, second joint 
with a black ring; sockets at their base with an uninterrupted black margin. Head 
above with two parallel black stripes confluent anteriorly with the black margins of 
the antennse sockets; face with an orange-red spot each side upon the cheeks and a 
black crescent under each eye, its anterior horn running into the black margin of the 
antennse sockets. First segment of the thorax with an impressed line in its middle, 
and three brown spots on each side, behind which are two black dots and a fourth 
brown spot situated upon the basal edge; second segment with two short black lines 
upon its anterior and two brown spots near its posterior edge. Veinletsblacli, those in 
the disk green in their middle, those ending on the inner and apical marginsgreen ex¬ 
cept at their bases, those of the hind wings green except the row towards the tips, 
those outside of the rib-vein and the bases of those branching from the inner side of 
the rib-vein. Wings expand 1:15. My specimens of tlfs species were captured in 
the State of Mississippi in April. 
4. (3.) Veinlets green, slightly marked with black at their 
bases. 
The Disagreeable Golden-eye (C. illepida). Pale yellowish green clothed 
with short white hairs. Head yellowish white, pale yellow above with two black 
stripes which are often dusky in their middle and slightly converge anteriorly, their 
anterior ends confluent with the black margins of the antennse sockets; a black dot on 
the base behind each eye. Antennae pale yellow, becoming dark brown towards 
their tips; basal joint white with a pale tawny spot on the upper side; second joint 
with a black ring; sockets broadly margined with black except above between the 
anterior ends of the longitudinal stripes where is an interruption of bright tawny red. 
Eyes dark golden green. A black crescent under each eye, the anterior horn of 
which joins the black margin of the antennse sockets in the middle of their under
