not belong to this series at all. Mr. Grote has also seen the type and 
suggests that it seemed to him close to muralis. ie

“$. The tibial claw is present, and the testaceous antenne are bipectinated, 
somewhat less heavily so than in D. muralis. The colors are mainly those of D. mu- 
ralis, but the wings are more uniformly fuscous to the subterminal line, and then the 
terminal space contrasts by its frosty, grayish white. Fringes distinctly checkered, 
fuscous and white; with the terminal line nearly obsolete, not resolved into black 
dots as in D. muralis. Ordinary spots ill defined, whitish, the reniform inwardly 
sharply margined with black, smaller than in D. muralis ; orbicular rounded, black 
edged. Claviform quite small, concolorous, black edged, removed from the orbicu- 
lar, hence very different from that of D. muralis. A fine basal black ray. No black 
streak above internal angle, and no black shading across the median space opposite 
the claviform. The median lines are distinctly marked with black, in general shape 
resembling those of D. muralis, but differing in slight details. The primaries are 
more pointed than in D. muralis, narrower and with the external margin more ob- 
lique, straighter and a little depressed before internal angle. Hind wings smaller, 
pale fuscous with traces of a double line on the veins, and with the faint terminal 
line not broken into points. Beneath much as in D. muralis ; on the hind wings the 
discal mark is larger and tends to fuse with the median line, the latter exserted at 
this place, so that a fuscous O may be more or less completely outlined by the line 
and the discal lunate mark. Thorax hoary gray, the tegule black lined.

HABITAT: Massachusetts, Texas. 
This species seems rare. I have seen but few Specimens, and these 
showed little variation. It is smaller throughout than muralis and, as 
Mr. Grote says in the description quoted, the wings are narrower and 
lack the transverse line crossing the median space.

Four species seem referable to this genus—bombyciformis, rolandt, 
depilis, and damalis, all easily separated. 
Bombyciformis is dark gray as a rule, with a black basal dash which 
meets the t. a. line from costa in an easy Curve, and incloses a triangular 
Space which in pale specimens is marked with rusty red brown. The 
S. t. line is usually distinet, most prominent and whitish opposite the 
anal angle, where it is marked with a blackish brown patch. The disk 
of the patagiz is discolorous, pale gray. 
Depilis is an ashy gray Species in which all the markings are lost, 
Save that the s. t. line is traceable and forms a whitish lunule in the 
submedian interspace. The ordinary spots are more or less completely 
defined by a narrow black line, and the space between them is very 
slightly darker.
