of distinct, blackish terminal lunules, Fringes dusky, witli a pale line at base. 

 Claviform wanting. Orbicular moderate in size, oblique, oval, defined by darker 

 scales, a little paler filled. Reniform rather large, kidney-shaped, defined by 

 black scales, somewhat gray filled. Secondaries powdery, blackish, with a black 

 terminal line and paler fringes. Beneath gray, powdery, both wings with an 

 incomplete outer line, and a black discal spot. Expands 32-33 mm. ; 1.28-1.32 

 inches.

Two female specimens are before me, both of them in fair condi- 

 tion. The distinct and prominently contrasting median lines mark 

 this species at sight. It bears a distant resemblance to that seiies 

 of Hadena, of which leucosceUs and hillii are typical ; but lacks all 

 trace of the abdominal tuftings. From the other species referred to 

 the present genus, it is abundantly distinct. 1 have had this species 

 in my possession for over three years, awaiting relatives before de- 

 scribing it ; and such as 1 have now found are not very close. 



Perigea veterafa n. sp. (PI. iii, fig. 7) — Ground color a very pale whitish 

 luteous. Head and thorax concolorons, immaculate, palpi laterally dusky. Pri- 

 maries powdered with black scales, which become so numerous beyond the t. p. 

 line that the wing there is blackish. All the macnlation is diflFuse and obscure ; 

 but all of it is at least traceable. Basal line single, blackish, broken. T. a. line 

 blackish, very oblique, irregular. T. p. line narrow, black, crenulated, moder- 

 ately outcurved over the cell, a little incurved below; single, except that the 

 outer part of the defining line is indicated toward the costa by the dark s. t. 

 space. S. t. line of the ground color, irregular, appearing broken and rivulous 

 through the dark outer part of the wing. A series of more or less distinct 

 blackish terminal lunule.s. A more or less obvious median line is outwardly 

 oblique from the costa, darkening and obscuring the reniform, thence near to 

 and parallel with the t. p. line, petering out toward the ianer margin. Claviform 

 not traceable in the specimen before me. Orbicular round, vague, indefinite, 

 concolorous, traceable only by a few blackish scales. Reniform better defined, 

 upright, blackish, narrow, somewhat lunate in shape. Secondaries white in both 

 sexes, veins dark marked, and a vague, dusky, outer marginal shade. Beneath, 

 primaries with a creamy tint, more or less powdery along the costa, an incom- 

 plete outer line and a vague discal lunule. Secondaries white, with a series of 

 outer dusky lunules, and a more or less distitict discal spot. Expands 36-39 mm. ; 

 1.44-1.56 inches. 



Hab. — Glenwood Springs, Colo., September and October ; Barnes, 

 Nos. 445, 446, 447. 



Three specimens, representing both sexes are before me, none of 

 them perfect, but all of them in at least fair condition. The species 

 is unlike any other of the genus that is known to me, and belongs 

 to the series containing the large winged forms like alholahes, which 

 this species most nearly resembles in habitus, while totally distinct 

 in color.
