 broad ; the transverse part of the vein M two received slightly 

 proximad of the middle. Length 4 mm.

ADITA CHIONANTHI A. & S. (LEPIDOPTERA) FEEDING 

 ON TRIOSTEUM PERFOLIATUM L. 



By Chas. Rummel, Newark, N. J. 



The identity of some unknown larvae observed for several 

 years feeding on horse gentian or fever wort was disclosed in 

 1919 by the emergence of a fine specimen of this handsome 

 noctuid reared out of five larvae. 



More persistent search in 1920 resulted in finding four small 

 larvae on May 10, twelve, also very small, on May 22 and five, 

 half grown, on May 28. 



The smooth larva in its early stages is green with a pale blue 

 stripe along the center of back; at maturity, when about i^ 

 inches long, its color changes to dull green and there are three 

 parallel stripes along the back, the center one light brown, the 

 outer ones reddish brown. When quite small the larvae feed 

 upon the tender tips of young leaves. Approaching maturity 

 they attack older leaves as well and while resting seek conceal- 

 ment by clinging to the stalks of the food plant or other objects 

 near by. Pupation takes place within the soil. The pupa is 

 chestnut brown and about % inch in length. The moth appears 

 during the first half of September. 



Observations were made at the Essex County Park on the 

 Orange Mountains, N. J.
