Secondaries yellow, with black boi-ders. Beneath both wings very pale yellow 

 powdered with blackish, with black outer border, and with a small blackish 

 discal spot. 



Expands, .80^ — i.oo inch., 23 — 25 mm. 



Habitat— Ox., Br. Col., Col., Nev., Ariz., Texas (.?). 



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 yfaz^a 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 palev 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 oi flava. 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 o{ flava. 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 patagi3e 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 mar;^in. S. t. line paler, faint, irregular. An oblique black 

 shade, consisting of two black dift'use 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 renifoim and close to and parallel with the t. p. line is 

 a narrow black shade line indistinct towards costa, but distinct below reniform 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, i.oo — 1.12 inches, 25 — 28 mm. 



Habitat — 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.
