NEUROPTEROUS INSECTS. 
pus white; abdomen with a slender, longitudinal 
line, and slender basal annulation on each segment ; 
beneath whitish, with a black line; feet black; 
thighs yellowish beneath ; tibiae yellowish above. 
Length over one inch and three-fourths. 
Of this fine species, Mr. Nuttall presented me two 
individuals which he obtained from Missouri. The 
bright sanguineous color of the wings in one sex 
terminates abruptly, and in the other the very pale 
yellowish-brown color of the same part gradually 
disappears towards the middle. 
In the A. caia, Drury of South America, (A. 
Brightwelli, Kirby?) the inferior pair of wings have 
a reddish spot at tip. 
It is very abundant in some situations in Indiana, 
and is easily taken.
