CATOCALA OBSCUBA, NOT. SB. 
(PLATE Til, FIG. 4 ^ ) 
Expands 2^ to 2J inches. 
Thorax above, dark grey ; abdomen black ; beneath dirty white. 
Upper surface, primaries dark smoky grey, pretty evenly colored ; transverse anterior 
and posterior lines black, varying somewhat in width and distinctness in different examples ; 
a sub-terminal grey band between two brownish ones; in some examples an almost obsolete 
reniform, but in the majority this appears to be replaced by a small round deep brown or 
black discal spot ; sub-reniform open. 
Secondaries black; fringes white, and in some cases black and white. 
Under surface white, with black bands. 
Habitat. Yew York. 
I received a number of this species from Mr. Angus who took them in the vicinity of the 
village of West Farms, X. Y. ; he says they arc difficult to discover, as they secrete themselves 
in the crevices beneath the bark of trees, and the rustling of leaves, &c., will not start them 
from their hiding places ; nothing short of hard raps against the tree trunks will do it. It 
does not appear to be very rare ; I have seen examples in various collections for a number of 
years past under the name of Laehrymosa, Vidua, and Insolabilis, so to get it out of its ob- 
scurity, and as its appearance is more obscure than any of its allies, I have christened it accord- 
ingly.
