NORTH AMERICAN LEPIDOPTERA. 73 



black i)owderiiigs on the veins, a blackish discal luiiule, and a distinct, though 

 narrow marginal band. Fringes blackish, with a white line at base. Beneath 

 white, powdery, both wings with a marginal, somewhat lunate black line, and 

 an ovate discal mark ; primaries with a somewhat vague median line. Expands 

 40 mm. : 1.60 inches. 



Hnb. — Glenwood Springs, Colo., September; Dr. Wm. Barnes, 

 No. 41. 



A single male s|)ecimen only, which at first sight resembles a 

 Mamedra allied to subjnncta. 



The antennje are serrated, the teeth set with bristle tufts. The 

 wings are narrower than in inedialls, and more as in (ecloti; the 

 fringes are somewhat excised and, altogether, the species is quite 

 distinct from any of the described forms known to me. 



Ilydrtecia iiiiinioda n. sp. (PI. i, row 2, fig. 6)— Ground color a dull pow- 

 dery luteous with a reddish or purplish admi.xture, most marked on the thoracic 

 disc. Head and thorax else concolorons. Primaries with a vague yellow- blotch 

 at base, and a distinctly limited patch at apex. There is a lighter purplish red 

 powdering in the basal space, and a very much more distinct shade in the s. t. 

 space. The terminal space is darker. Basal line geminate, brown, interrupted, 

 sometimes almost obsolete. T. a. line geminate, brown, incomplete, irregular, 

 almost upright, and with a wide outcurve in the space below the submedian vein 

 only. T. p. line geminate, brown, the inner line lunulate, continuous, the outer 

 line more even and somewhat more diflfuse. included space of ground color. In 

 course it is only a little outcurved over the ceil and almost evenly oblique below 

 that point. S. t. line lunulate, interrupted, rather even in course, more or less 

 marked, and sometimes accompanied by a yellow shade. A pale line at the base 

 of the fringes, which are darker than the wing. A fairly obvious, rather diffuse 

 brown, median shade, outwardly bent between the ordinary spots, and evenly 

 oblique inwardly, below. The ordinary spots are small, ill-defined, and very 

 little paler than the ground color. The claviform seems obsolete in the specimen 

 before me. Secondaries paler, more sordid luteous, with fuscous powdering, a 

 discal lunule, a median line, a faint trace of an outer line and a dark line at the 

 base of the paler fringes. Beneath paler, powdery, with an outer daik line, and 

 on secondaries a small discal spot. Expands 3G-39 mm.; 1.44-1.56 inches. 



^a6.— Colorado, Bruce (Nos. 122, 244). 



Two male specimens are before me, differing somewhat in the in- 

 tensity of the ground color, but not otherwise. The antennae are 

 simple, with a ciliation of fine hair. Tlie anterior tuft of the thorax 

 is prominent, much as in H. nitela, while the type of maculation i.s 

 not unlike that of the ruiila series. 



llydrfleeia senilis n. sp. (PI. i, row 1, fig. 6)— General color a pale reddish 

 luteous, scarcely rusty, yet verging on that shade. Head and thorax concolor- 

 ous, immaculate. Primaries very evenly colored. Basal line vaguely traceable, 

 geminate. The median lines are geminate, the difining lines of a darker shade 

 of the ground color, slender and unusually separatt-d, so that there is a veiy
