line in the lower part of its course. A row of dark fuscous terminal lunules. 

 Fringes very long, pale at base, darkening outwardly, and there faintly cut with 

 blackish. Secondaries white, somewhat iridescent, with a faint discal luuule, a 

 narrow median line and a broad, smoky outer band. Fringes long and white. 

 Beneath, the primaries are glistening, smoky and somewhat powdery outwardly, 

 with an outer line distinct about half way across the wing, a dusky discal spot 

 and a row of terminal lunules. Secondaries white, a small discal spot, a distinct 

 narrow median line not reaching the internal margin ; a narrow, somewhat in- 

 definite and incomplete smoky outer margin, and a series of fuscous terminal 

 lunules. Collar with a dusky line at base, aud a similar line near tip, below 

 which is a whitish shade. Thorax also with black scales intermixed. Expands 

 1.25—1.37 inches ; 31—34 mm. 



Hah. — Texas (October), Colorado. 



This species, originally described from Texas, I have seen only 

 from Colorado, quite a number of specimens having been taken of 

 recent years in that State. 'J'he species is readily distinguished by 

 the distinct niaculation, pale color, round reniform and white secon- 

 daries, which show a distinct discal lunule, as well as a narrow outer 

 line in addition to the usual dusky outer margin. 



The harpes of the male genitalia are somewhat curved, narrowing 

 toward tip and there somewhat truncate, the angles rounded ; an 

 oblique row of spinules at inner side of tip. The clasper rises from 

 the middle of inferior margin and does not extend the full width of 

 the harpe. It is even for about half its length, then narrows rapidly 

 from the inner side and terminates in a long, acute point, resembling 

 simplex somewhat in this respect, but with a different harpe. 



O. iricolor Smith, Insect Life, 1888, i, 19. 



Head, thorax and primaries somewhat pale luteous, the primaries more or less 

 powdered with bluish black atoms which have an iridescent, metallic glitter. 

 Basal line present, black, followed by a narrow pale line. T. a. line geminate, 

 outer line black, inner line more or less punctiform, the included space pale. 

 As a whole, the line is somewhat irregular, very slightly curved outwardly. At 

 the inner margin the line is preceded by a large patch of metallic dark scales, 

 which in one specimen crosses the entire wing and in the other is limited to the 

 inferior third. Claviform small, pale, not defined ; orbicular rather small, round, 

 a little irregular, pale ringed, centre concolorous. Keniforra moderate, upright, 

 somewhat constricted medially, pale ringed ; a somewhat fuscous median shade 

 darkens the cell between the ordinary spots and continues as a narrower dark 

 shade parallel and close to the t. p. line. T. p. line narrow, black, crenulate, 

 interrupted, widely curved over the cell and then with a regular inward curve 

 to the hind margin. The narrow black line is followed by a broader, more even 

 pale line, from which point the s. t. space darkens aud becomes metallic black to 

 the irregular, pale and somewhat interrupted s. t. line; a row of terminal dusky 

 lunules inwardly margined by pale scales. Fringes unusually long and pure 

 white. Secondaries faintly yellowish, glistening, with a broad black border and
