outwardly deeply indented and black marked. There is also more or 
less black between the ordinary spots. The female is very often quite 
uniform in color, the markings disappearing in the uniform soft gray 
tint, and the characteristic reniform alone showing prominently—from 
this form to the typical strongly marked male all intergrades are present. 
This is the species most usually marked chalcedonia in collections, 
and which I have heretofore so determined. I have not seen festivoides 
identified in collections but am quite certain that this is the species in- 
tended by Guenée. His description tallies in all points. 
The wings are comparatively somewhat shorter and_ broader 
than in the other species. The harpes of the male are as in the 
other species ; the clasper consists of a moderately long spoon-shaped 
corneous process with a little acute hook at tip. The species is common 
throughout the middle states, extending to Texas in the south-west and 
probably to the Rocky Mountains, though I have seen no specimens 
from further west than Missouri. .

Head, thorax and primaries grayish-brown, the costal region of primaries paler, 
and sometimes head, thorax and basal and costal region of primaries luteous, the re- 
mainder of wing then of the more usual sober brown. Basal line, when present, 
geminate ; darker brown—in pale specimens the line is wanting. T. a. line geminate, 
outwardly oblique and somewhat sinuate, the included space somewhat paler. In 
pale specimens the line is wanting either in part or entirely, TT. p. line outwardly 
bent over reniform, then somewhat sinuate, but as a whole outwardly oblique to the 
hind margin. It is geminate, the iuner line distinct, the outer fainter, sometimes 
punctitorm, The line is accompanied by a broad, diffuse whitish shade band, most 
distinctly marked on costa and very variably distinct below that point. Beyond this 
band the wing is somewhat evenly colored, broken into only by the pale, luteous 
apical patch, from which starts the more or less obsolete s, t. line which is pale, 
broken and irregular. Claviform small, pale, oval, very much of a size and form 
with the orbicular, which is often quite indistinct or even absorbed by the pale shad- 
ing. Reniform small, oblique, a trifle paler, black ringed. A black mark between 
it and orbicular and another between it and t. p. line. Secondaries white, hyaline, 
with margins soiled and smoky. Beneath pale, powdery, with a distinct outer line. 
Collar with a central, darker transverse line.
