AMERICAN LEPIDOPTERA. 215 



Hab. — Hackley, Texas, in April. 



Three male and two female examples in poor condition, through 

 Mr. George Franck. As compared with natatrix (tenuis) this is 

 much smaller, with shorter, more trigonate primaries, in which the 

 outer margin is not obviously angulated. The palpi are also shorter 

 and the markings are quite characteristic. The species seems to be 

 locally common, and specimens are in several collections as tenuis — 

 through my fault. 



Yrias albiciliatus n. sp. — Head and thorax pale pink ; like a pink flush 

 over a white base. Primaries ranging from pink at base to brick-red in the ter- 

 minal space; outer half of basal space and all of the s. t. space leaden gray ; alto- 

 gether a very pretty species, with well defined contrasts and markings. Basal 

 line geminate, gray, included space brick red, forming the inner limit of the gray 

 fascia that extends to the t. a. line. The latter is geminate, inner defining line 

 blackish, outer line narrow and brown, included space brick red ; as a whole out- 

 wardly oblique and only a little irregular. T. p. line geminate, inner line very 

 narrow, gray, outer line darker, merging into the dark s. t. space, included shade 

 brick red ; as a whole the line is squarely exserted over the cell and nearly 

 straight from below the reniform to the inner margin. S. t. line irregularly and 

 deeply sinuate, at two points almost touching the outer margin, defined by the 

 difference in color between the leaden gray s. t. and brick red terminal spaces. 

 On each side of this leaden gray band there are white dots on the veins. There 

 is a festooned terminal line, beyond which, on the incurves, are red tunnies, and 

 on the outcurves blackish gray spots at the base of the very long whitish fringes. 

 A quadrate gray blotch at the middle of the costa indicates the beginning of a 

 median shade which is marked only by a few gray scales to vein 1, below which 

 it is distinct to the margin. The orbicular is wanting in the specimen. Reniform 

 indicated by a few gray scales forming a very fragmentary outline. The pale 

 pink of the median space becomes brick red in the square exsertion of the t. p. 

 line. Secondaries whitish at base, leaden gray beyond the middle, the inner 

 margin of the dark area irregular. Fringes long and white. Beneath, wings 

 white at base, with a broad blackish outer band ; fringes white. Expands .84 of 

 an inch = 21 mm. 



Hab. — Yuma County, Arizona (Hutson). 



A beautiful little species, represented by one very good female 

 specimen. The species is not really an Yrias, but it resembles that 

 genus in general form, and may remain here until further material 

 makes a better reference possible. 



Yrias strigalis n. sp. — Ground color a smoky yellowish brown, with an 

 admixture of metallic bluish gray scales. Head darker, seal-brown. Collar 

 intermediate in color between the head and thorax, which is of the same color 

 as the primaries. Wings transversely strigate by alternate rows of smoky and 

 gray scales over which the maculation is obscurely writen in smoky brown. Pri- 

 maries without contrasts; a blackish apical spot, outwardly defined by a yellow
