Secondaries yellow. with black borders. Beneath both wings very pale yellow 
powdered with blackish, with black outer border, and with a small blackish 
discal spot.

A rather variable species, yet readily recognizable. 
The reach of variation, and the characters separating crocea are thus 
given by Mr. Grote: *‘This form only differs from the typical fava from 
British Columbia by the primaries above being shaded with pale, espec- 
ially on the disc, and being more yellowish, beneath at base, contrasting 
with the black border. These colorational characters do not seem to be 
constant, for in one specimen from Oregon the pale shading is confined 
to a space about the reniform, and in a still paler crocea, from Colorado 
the contrast between the yellow base and the black terminal band is not 
as great as usual. I think crocea is a variety of fava. In both the ex- 
terior line is outwardly bent over the median nervules and followed by a 
whitish and then a brown shade.” 
From the material at my command I would refer crocea as‘a syn- 
onym rather than a variety of fava. There is no possible line between 
the two, geographical or otherwise. 
P. singula Grt. Can. Ent., 12, 215, 1880, Pseudanarta. 
Head, thorax and primaries blackish fuscous, varying to dark gray. Thorax 
with the patagize black edged. Primaries with the maculation distinct. Basal half 
line variably distinct, but always visible, geminate, arquate. A black longitudinal 
dash, somewhat varying in length—a black mark along inner margin, also somewhat 
variable in extent. T. a. line geminate, inner line usually faint, the outer black ; 
outwardly curved and bent, and with a longer outward angle on the internal vein. 
T. p. line bent over reniform and well removed from it, decidedly angulate opposite 
the inferior portion, thence with a slight inward curve and somewhat tremulous to 
hind margin. The line is geminate, the inner portion black and sharply defined, the 
outer more or less obsolete. Beyond the t. p. line a paler shade prevails, gradually 
darkening to the outer maryin. 5. t. line paler, faint, irregular. An oblique black 
shade, consisting of two black diffuse dashes, extends from below apex nearly to t. p. 
line at its angulation beyond the cell. A broad black mark connects the median lines 
below the median veins. Orbicular large, oblique, ovate, slightly paler, black ringed. 
Reniform large, upright slightly constricted medially, somewhat paler, rather inde- 
finitely outlined. Beyond the reniform and close to and parallel with the t. p. line is 
a narrow black shade line indistinct towards costa, but distinct below renitorm to the 
internal margin. Secondaries yellow, with a broad black outer margin. Beneath 
primaries very pale yellow, powdered with black and with a broad black margin, 
Secondaries as above. 
Expands, 1.00—1.12 inches, 25—28 mm. 
Hatbitat—Texas, Arizona. 
A broader winged and larger species than flava and very distinct 
from it in markings. The large ordinary spots and the oblique black 
shade below the apex are characteristic.
