84 APPLE LEAVES — CHRYSOPA SPECIES. 



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, t"hey 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). Antennae wliitish, 

 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 antennae sockets; face with an orange-red spot each side upon the cheeks and a 

 black crescent under eacheye, its anterior horn running into the black margin of the 

 antennae 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. Veinletsblack, those in 

 the disk green in their middle, those ending on the inner and apical marginsgreeu 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 this species were captured in 

 the State of Mississippi in April. 



4. (3.) Veinlets green, slightly marked with black at their 

 bases. 



The DisAOBEEABLE GoLDBN-ETE (C . ilhpida) . Pale yellowish green clothed 

 with short white hairsi 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 antennae sockets ; a black dot on 

 the base behind each eye. Antennje 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 born of 

 which joins the black margin of the antennae sockets in the middle of their under
