ternipted, preceded by a series ofsuiall black spots. A few white scales Iq S. t. space 

 OT)posite cell, and a rather large indeliuite pale spot tilling the space near hind margin, 

 a row of black terminal lunulcs. Fringes dusky, cnt with darker fuscous and with a 

 fuscous line at base. Secondaries smoky at base, limited by a sinuate black baud, 

 then a luirrow white baud, followed by tbe broad, black outer margin. Fringes white. 

 Beneath, both pairs of wings smoky at base, with a common black median band, fol- 

 lowed by a broader white baud, the outer margin broadly black. 



Expands .88 inches— 22™'". 



Habitat Colorado. 



A single female in Mr. Tepper's collection. The species is an easily 

 recognized one. Its small size and tlie banded secondaries are nnnsual. 

 The primaries are somewhat broader and shorter than nsual, and the 

 body somewhat less robnst. The eyes are not very distinctly lashed. 



Despite its somewhat abnormal appearance I believe the species cor- 

 rectly referred here. 



0. iiiicoLoii sp. nov. 



Head, thorax, and primaries somewhat pale luteous, theprimaries more or less pow- 

 dered 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 detiued. Orbicular rather small, round, a little irregular, pale ringed, cen- 

 ter coucolorous. Reuiform moderate, upright, soujewhat constricted medially, pale 

 ringed. A somewhat fuscous median shade darkens the cell between the ordinary 

 spots, and continues as a narrower dark shade, parallel with 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 fol- 

 lowed by a broader, more even pale line, from which point the s. t. space darkens 

 aud becomes metallic black to the irregular, jiale, and somewhat interrupted s. t. line. 

 A row of terminal, dusky lunules, inwardly margined by pale scales. Fringes u'ju- 

 sually long and pure white. Secondaries faintly yellowish, glistening, with a broad, 

 black border and a distinct discal luuule. Fringes also pure white. Beneath the 

 wings are very pale whitish yellow, with broad, blackish outer margins, the discal 

 spot of scoudaries more distinct. Head with a few reddish scales between the an- 

 tennae. Abdomen like wings beneath. Expands 1.25 inches = 31-32"'"'. 



Eahitat, Colorado. 



Three specimens, all females, 1 Coll. U. S. National Museum (Smith 

 Coll.), the others Coll. F. Tepper. 



This is perhaps the most beautiful species of the genus, the metallic 

 dark scales and the very long white fringes offering distinctive charac- 

 ters. The specimens differ considerably in the amount of metallic irro- 

 ration ; one so covered as to darken the entire specimen, another spec- 

 imen with the dark markings only metallic. The species is most nearly 

 allied to augustus^ Harvey. 



0. TERMINALIS sp. UOV. 



Head, thorax, and jirimaries dull fusco-luteous, primaries with a broad, blackish 

 terminal shade. Basal line of primaries faintly indicated by a few black scales. T. 

 a. line geminate, marked on costa by distinct black spots, then becoming very faint, 

 traceable principally by the paler inclosed space, and again becoming distinct below
