GROTE ON NORTH AMERICAN PYRALID^. 699 



"Early in October, I found pupa3 of this insect at Niagara Falls, on 

 the Canada side, under shelter of loosened portions of the bark of the 

 American Elm. They were enclosed in a cocoon of silk, mixed with par- 

 ticles of bark. On the same tree I took a number of larvae which were 

 descending the trunk to undergo pupation. I did not, however, obtain 

 imagos from any of the specimens. The body was nearly uniform in 

 diameter, with the ordinary number of feet. Head as broad as the body 

 and dark green. Body dark green, between the segments yellowish and 

 dotted with yellow; first rings with two black dots on the sides." — Proc. 

 Acad. Nat Sci. Phila. 18G0, p. 205. 



PiNiPESTis Grote. 



Head with a transverse thick ridge of scales behind; frontal scales 

 forming a projecting bunch. Maxillary palpi alike in both sexes, con- 

 cealed by the porrect labial palpi, which exceed the front. Ocelli. Male 

 antennae thicker than in the female, with the joints not apparent, very 

 slightly bent at base, where they show a ridge of thin tuftlets of scales, 

 pubescent beneath. Fore wings 11-veined, with veins 

 4 and 5 running close together at base, but having a 

 separate origin. Hind wings 8- veined, vein 5 running 

 close to 4, but independent, and continuous with the 

 cross vein.

<? ?. Blackish-gray, shaded with reddish on the 

 basal and terminal fields of the fore wings. There 

 are patches or lines of raised scales on the basal field ■^'^•^*^' 



and on the anterior and darker portion of the median space behind the 

 transverse line; also the exterior line and discal mark are accompanied 

 by raised scales. Median lines prominent, consisting of double black 

 lines enclosing pale bands. The inner line at basal third is per- 

 pendicular, dentate. The outer line at apical fourth is once more 

 strongly indented below costa. The median field is blackish, be- 

 coming pale outwardly; it shows a pale, sometimes whitish, discal spot, 

 surmounted by raised scales. The terminal edge of the wing is again 

 pale or ruddy before the terminal black line. Fringes blackish. Hind 

 wings pale yellowish- white, translucent, shaded with fuscous on costal 

 region, and more or less so terminally, before the terminal blackish line; 

 fringes dusky. Beneath, the fore wings are blackish, marked with pale 

 on costa ; hind wings as on upper surface. Body blackish gray, with 

 often a reddish cast on thorax above and on the vertex. Abdomen gray, 

 annulated with dirty white ; legs dotted. Expanse, 26-30 mil. 



The species varies in the amount of reddish on the basal and terminal 

 fields ; the raised scales are easily lost in handling the living specimens.
