Inhabits Indiana. 



Body blackish ; head and thorax varied with yellowish ; wings, 

 on the apical third, varied with flesh color, and a large trifiirious 

 undulated, blackish mark; superior pair with a few blackish 

 spots on the middle nervures, and on those of the anterior sub- 

 margin ; feet fuscous, with a yellowish line. 



Length to the tip of the wings, about two inches. 



This beautiful species is very rare. 



A specimen was presented to me by Mrs. Corson ; it was taken 

 at her residence, near Evansville, Indiana. 



Thd palpi in the specimen are deficient.

CHRYSOPA Leach. 



C. OCULATA. — Pea-green j head and thorax spotted ; tarsi 

 brownish. 



Inhabits the United States. 



Antennae pale brownish ; first joint white, with a sanguineous 

 band at base above, second joint black ; eyes golden ; palpi al- 

 ternately black and white ; labrum with two dilated sanguineous 

 vittse ; between the eye and mouth is a black, angulated line j 

 base of the anteunae enclosed by two black circles ; which are 

 tinged with sanguineous above; above each antenna are two 

 blackish spots, of which the anterior ones are sometimes con- 

 fluent with the [46] circles of the antennae; thorax with two 

 series of three blackish spots in each, and two or three lateral 

 spots ; wings hyaline, iridescent, having the transverse nervures 

 varied with black; tarsi pale brownish-yellow. 



Length to the tip of the wings three-fifths of an inch. 



This beautiful little insect is very common. When irritated, 

 it difi'uses a strong ofifensive odor, similar to that of human ex- 

 crement. It is the analogue of the C. perla L., with which I 

 have hitherto confounded it, but, judging by Donovan's figure, 

 it is never so large. Donovan says the perla stinks before a 

 storm ; our species has always that quality when irritated or 

 alarmed.
