side are repeated; base of secondaries white slightly sprinkled with brown 
scales; a brown discal dot followed by a broad median band, defined by brown 
scalloped lines and shaded within with light brown; subterminal and terminal 
areas as above, but the brown much lighter, not smoky; fringes on both wings 
as on upper side. Expanse 26 mm. 
Hasitat. White Mts., Arizona (Lusk). 14 ¢. Type, Coll. Barnes. 
This species is apparently the same as that figured by Druce (PI. 
55, Fig. 13) as the 9 of Larentia columella; our specimens, all ¢’s, 
do not however correspond with the figure and description of columella 
g and we imagine that two species are represented. The name 
columella must be retained for the g with immaculate secondaries. 
XANTHORHOE DENTILINEA sp. nov. (Pl. VII, Figs. 4, 6). 
$. Antennae bipectinate, palpi smoky brown, head and thorax pinkish, 
sprinkled with black, abdomen pale fuscous, shaded dorsally with pink, with 
double row of black dorsal spots and white line at posterior portion of segments ; 
primaries, basal portion deep purple-brown bordered outwardly by a pale yellow 
subbasal line and containing faint traces of cross-lines, most marked on inner 
margin; subbasal line oblique from costa to radius, then almost perpendicular 
and slightly waved; space between subbasal and antemedial lines paler, shaded 
with pinkish; antemedial line geminate, pale ochreous filled with purple-black, 
strongly and evenly oblique from costa to submedian fold, then with strong in- 
ward angle on vein 1, approaching close to subbasal line; median space to 
postmedial line filled by a broad band of deep purple-brown; the central portion 
of this band is paler and contains a connected series of irregular lozenge-shaped 
patches of which that in cell is the largest and contains a faint discal spot; 
post-medial line pale ochreous, defined outwardly by smoky line, incurved oppo- 
site the cell, outcurved at vein 4 and again incurved slightly in submedian fold; 
beyond this are traces of several parallel lines crossing the wing, marked on the 
veins by black dots; subterminal space pale pinkish with slight dark patches 
on costa; subterminal line white, lunate, broken, preceded opposite cell and 
above anal angle by slight dusky shading; an oblique ochreous dash from apex 
of wing to subterminal line below which the whole terminal area is shaded with 
rather smoky brown; a fine dark terminal line; fringes, inner half purplish, 
outer pale rosy, slightly checkered with smoky-brown. Secondaries pale smoky 
with slight rosy tinge, postmedial and subterminal lines of primaries continued 
distinctly across wing; traces of other lines basally and subterminally. Beneath 
primaries smoky, outer half rosy; postmedial line of upper side distinctly out- 
lined in smoky and a few faint white dots in the position of subterminal line; 
faint discal dot; secondaries rosy, heavily sprinkled with smoky; small discal 
dot and fine waved postmedial line; dark terminal hair-line to both wings; 
fringes as above. 
@. Same as ¢, but pale areas much more ochreous and without the pink 
tinge. Expanse 25 mm.
