84 APPLE LEAVES CHRYSOPA SPECIES. 



evidences which compel us to regard these minute and seeming- 

 ly unimportant marks as valid indications of differences which?, 

 actually exist in nature. 



To facilitate the discrimination of these species of this genus 

 which are here described, they are arranged in an analytical se- 

 ries, 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 (Chrysoja albicornis'). Antennse whi- 

 tish, basal joint with an orange-red ring surrounding it wholly or in part, se- 

 cond 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 run- 

 ning into the black margin of the antennae sockets. First segment of the tho- 

 rax 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. Veinlets black, those in the disk 

 green in their middle, those ending on the inner and apical margins green 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 in- 

 ner side of the rib-vein. Wings expanded 1.15. My specimens of this species 

 were captured in the State of Mississippi, in April. 



4. (3.) Veinlets green 3 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 an- 

 teriorly, their anterior ends confluent with the black margins of the antennae 

 sockets; a black dot on the base behind each eye. Antennae pale yellow, be- 

 coming 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 mar- 

 gined 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 sides, and
