The female resembles tlie male in markings, but is much darker. 
The head, thorax, abdomen and anterior wings, fulvous; the abdomen 
having one row of dorsal, and two, of lateral black dots : the posterior 
wings, very black, the costa of which, also fulvous. Below, brick red, 
in ornamentation the same as the male. Legs, reddish-brown. Length 
of body 3f lines; of the wings Ilf lines.

My specimens were obtained near this city by the kindness of Mr. 
Greo. W. Tryon, Jr. It approaches some varieties of ruhicundaria in 
its ornamentation, but the terminal band on the posterior wings of that 
species, is here developed, until it covers the whole surface, excepting 
a small portion of the costal edge. 
3. C. immacnlata, nov. sp. 
Antennae, long, fulvous; head, thorax and abdomen, pale ferrugi¬ 
nous, a row of obsolete black dorsal dots on the last. Wings, fawn 
color, covered with a rosy blush, sub-hyaline, immaculate, above and 
below. Oosta of anterior wings, on the under side, rather more roseate 
than any other part of either surface. Legs, pale ferruginous. Length 
of body 3f lines; of the wings 12 lines.

This species has some resemblance to C. cupraria Walker, but on 
comparison, it will be readily seen, that the differences between them 
are too great to be reconciled and united under thatuiarne. 
I have several specimens, which, although they do not correspond 
with any described species or varieties, might perhaps be considered as 
a variation of ruhicundaria: or even ferruginosa^ if, indeed the latter 
be not simply a form of the first; yet in regard to their ornamentation, 
they would appear to approach more nearly the second group of the 
genus, that containing cupraria and Iseta. The vexed question of what 
are properly true species of this genus and which, their abnormal con¬ 
ditions, can only be satisfactorily determined, when due attention has 
been paid to their larval state, to their identification and transforma¬ 
tions. 
In coloration, my specimens correspond in the main with G. imnia- 
culata; no discal dots on either wings; a transverse obsolete, sub- 
marginal brown line on the primaries, beyond which the ground color 
becomes lighter; apex of primaries, tipped with black. Three large
