A decidedly variable species within certain limits, as to size, macul- 
ation and color. Sometimes it will be of an almost even dull fuscous 
brown, the costa but slightly paler, the maculation indefinite; then it 
will appear with bright distinct markings and even colors, and again 
with the entire base and costal portion of wing discolorous bright lute- 
ous, absorbing all the basal maculation. Between these there 1s every 
shade of variation—in fact scarcely two specimens of the large series be- 
fore me are even nearly alike. 
The type form as figured by Hiibner represents a specimen with the 
costa moderately pale, and otherwise well marked : /racéa Grt., is based 
on specimens in which the pale shading encroaches still more on the 
center of the wing, and is simply a somewhat more marked specimen of 
the type form, while arva Gn., is evidently based on well marked spe- 
cimens in which the costa is concolorous. Consequently chalcedonia, 
tracta and arna all refer to the same species—arna perhaps retainable as 
a poor variety. 
The genitalia are as to harpes of the usual type. The clasper con- 
sists of a broad corneous base from which is projected a rather large, 
sickle-shaped hook. 
The insect is common in the southern states and finds its centres 
of greatest abundance in Texas and Florida.

«¢ Dark brown with a more or less decided ruddy tinge. Primaries shaded with 
ochreous along internal margin, and with a well sized distinct deeper ochreous 
apical patch. Ordinary lines obsolete, whitish, broken by black points on the veins ; 
the t. p. line emanates from a distinct and large white spot on the costa above the 
vague reniform, which latter 1s preceded by a distinct black shade on the disk, an 
evident feature of the ornamentation of the wing. Hind wings uniform pale fuscous, 
silky ; beneath as above with a discal dot and distinct darker median shade line. 
Fore wings beneath blackish with traces of the continuation of the median line, paler 
terminally. Head and collar brownish ; tegulze paler; thoracic crestings tipped 
with blackish.” Expanse, 20 mm. 
Habitat—St. Catherine’s, Ontario; N. Y. June. 
This species I have identified in at least two collections but cannot 
recollect where. It struck me as a very distinct form, readily recogniz- 
able from the description and figure. It is perhaps nearest to some 
forms of arna, but has a hadifus quite different.
