150 Psyche [Oct.-Dec. 



A NEW SPECIES OF HETEROCAMPA (LEP., XOTODOX- 



TIDiE.) 



By Wm. Barxes, M. D, and A. W. Lindsey, Ph. D. 



Decatur, 111. 



Heterocampa amanda n. sp. 



Head, thorax and abdomen light gray or brownish gray to dark 

 gray. Tufts and tips of patagia darker. Pectinations of <-^ 

 antennae long, gray-brown; shaft with some light gray scales. 



Primaries gray, the costa powdered with whitish scales and the 

 veins in part somewhat darker than the gi'ound color. Within the 

 basal area, below Cuo, and beyond the cell there are sometimes 

 paler, somewhat brownish areas. Basal line geminate, the outer 

 black, the inner gray, and the included space buff. T. a. line gem- 

 inate, faint, outwardly convex between the veins. This line is 

 oblique, almost reaching the middle of the inner margin, and is 

 slightly curved. T. p. line similar but with scallops reversed and 

 much slighter. This line is almost upright, but is slightly concave 

 outwardly beyond cell and inside of Cu^, leaving the usual square 

 projection between Cui and Mg. The s. t. line is made up of 

 two blackish shades, one almost straight from near apex to M,, 

 the other beginning outside of the first on Mg, running thence to 

 Cuo, and then curving outward toward the anal angle. Both ara 

 followed by vague slender whitish lines. There is a blackish ter- 

 minal line, sometimes cut by white on the veins, and the fringes 

 are concolorous with the wing, but -with blackish at the veins. 

 Cell terminated by a curved blackish line. Secondaries white in 

 male, the costa, outer margin (very slenderly), terminal quarter 

 and sometimes a short median portion of veins marked with gray- 

 brown. Eringes more or less grayish, darker at the veins. In 

 the female the secondaries are more gray-brown with a variably 

 definite band filling the terminal third and a less strongly marked 

 median shade and discal spot. Fringes grayish white, dark at the 

 veins. Under surface white in the male, the secondaries marked 

 much as above and the primaries darker toward costa and apex, 

 with only the markings of the fringes, a discal bar, and sometimes 

 a paler terminal area visible. In the female this surface is much 

 darker, as would be expected. The primaries are otherwise similar
