Xylomiges curialis Grote. 
1873. Grt., Buff. Bull., 1, 143, Xylomiges. 
Bluish ash gray, head and thorax concolorous, immaculate. Prima- 
ries with a faint reddish tinge. Veins black marked, irregularly inter- 
rupted by white scales. All the lines vague, indistinct. Basal line 
broad, diffuse, hardly darker than ground color, fairly distinct on costa 
only. T. a. line upright, geminate on costa only, irregularly dentate on 
the veins, a Jonger outward toothin the submedian interspace, repre- 
senting the claviform. An indistinct brown shade line accompanies 
the darker defining line and becomes somewhat diffuse in the subme- 
dian interspace. T. p. line vague, indistinct, marked by more promi- 
nent venular points, and defined mostly by adusky median shade which 
starts from the costa between the ordinary spots, darkens the outer 
half of the median space and obscures the reniform. The s. t. line con- 
sists of an oblique series of rusty, dark brown interspaceal dots, of 
which the lower and larger are emphasized by a few black scales. A 
series of black interspaceal terminal dots. Fringes dusky. Orbicular 
almost round, slightly irregular, not defined, somewhat paler than 
eround color. Reniform rather large, upright, constricted medially, 
centrally darkened by the median shade, rather incompletely defined 
by a dull, rusty brown annulus orring. Secondaries white, subhyaline, 
with a small discal spot and a broken terminal line, black. Beneath 
wings white, primaries with a somewhat smoky disc, a small black 
discal spot and a line of terminal dots on both wings black; seconda- 
ries with an extramedian, punctiform transverse line. 
Expands 38 to 40 millimetres=1.52 to 1.60 inches. 
HApitat: California, Alameda County, in March. 
This species is readily recognized by the more than usually robust 
body, the narrow primaries, of which the hind angle is somewhat re- 
treating, and the more xyliniform habitus. The thoracic tufts are small, 
the thorax itself plump and convex, the abdomen short and conic. 
The sexual characters are distinctive and unlike any other of the 
species. The harpes are broad, subequal to the tip where the lower 
angle is obtusely rounded, the upper produced into a long, trigonate 
point. A long curved corneous clasper closely follows the margin of 
the harpe, and is supplemented by a short, stout, obtuse process at 
base. 
Xylomiges dolosa Grote. 
1880. Grt., Can. Ent. x11, 88, Xylomiges. 
Ground color dull blackish, powdery, over a white ground, sometimes 
with a faint olivaceous tint. Collar quite obviously gray shaded; tho- 
rax less distinctly so. Abdomen blackish, powdered. The primaries 
are quite evenly colored, a paler shade visible in basal space and be- 
yond t. p. line, while a more obvious and often prominent whitish shade 
extends below the orbicular to the hind margin. The ordinary lines
