space and a paler apical patch in terminal space. Secondaries fuscous, with a 
broad black outer margin, a narrow preceding dusky line and a dusky discal 
lunule. Fringes pale, interlined with fuscous. Beneath powdery, primaries 
darker, both wings with a discal spot, narrow outer line and broad dark outer 
margin, all variable in distinctness. Expands 1.00--1.08 inches; 25 — 27 mm. 
Hub. — Colorado (Bruce); Las Vegas, N. Mex. (Meeske); New 
Mexico (Show); Arizona (Edwards). 
This little species has long puzzled me, and I refer it to Perirjea, 
rather because it is congeneric with P. pei'plexa Grt., than because 
it strictly belongs here. 
Four of the specimens collected by Mr. Bruce are in the collection 
of the United States National IMuseum, two of them labeled simply 
“ Colorado,” the others labeled “ Foot-hills.” There is little or no 
variation, and the species once generically [ilaced, is easily recogniz- 
able. 
l*oliit pul VPrnloiita n. sp — Ground color a powdery ashen gray, the 
markings indefinite, vague. Basal Hue black, interrupted, apparently single. 
T. a. line single, black, rather diffuse, outwardly oblique and somewhat outcurved 
between the veins. T. p. line crenulate. outcurved over the cell and parallel 
with outer margin below that point, blackish, interrupted, almost lunulated, and 
nearly obsolete toward costa. This line is quite well removed toward margin, 
widening the median space and narrowing the space beyond to the outer margin. 
A series of somewhat diffuse iuterspaceal black marks indicates the s. t. line: a 
series of small terminal lunules. Fringes gray. Claviform vaguely indicated 
by a blackish shade. Ordinary spots vague, indefinite, concolorous, incompletely 
outlined, apparently of the usual shape and proportionate in size. An oblique, 
diffuse blackish shade from costa, outwardly over the reniform and darkening 
it interiorly; continued as a vague fuscous shading through the median space. 
Secondaries dirty white, powdery, veins soiled, a dusky lunate marginal line and 
discal spot and extra discal line of under side showing through. Beneath 
whitish, powdery, with a common extra discal line and a discal spot on all wings. 
The hind angle of primaries is somewhat retracted ; thorax with a small, divided 
anterior crest, and a more distinct posterior tuft ; abdominal tufts small. Ex- 
pands 1.88 — 2.08 inches; 47 — 52 mm. 
Hab. — Colorado. 
Two male specimens with serrate and tufted (brush-like) tintenna. 
This species, though referred to Polia, jirobably cannot remain in 
this genus. It is referred there because it is quite close to and per- 
fectly congeneric with Polia contacta Wlk., which it resembles both 
in size, color and general habitus, differing abundantly in many re- 
spects. The species liears a very decided resemblance to Mamestra 
discalis, and a specimen in the Museum collection (from the Meske 
collection) bears Mr. Grote’s label, Mamestra discalis. The specimen
