'^10 [March 
distinctness of markings, sliape of median band and apical spot, in all 
which respects it differs from Unijuga. 
Catocala nebulosa, nov. sp. 
Expands inches. Thomx; dark broWn. Primaries ferruginous, 
pale in the disk and along the nertules to the hind margin, almost 
black at the base up to the basal line, except on the inner margin ‘ 
basal line slightly waved, but at the inner margin throwing out a pro¬ 
minent tooth that nearly reaches the elbowed line; this is well defined 
black, much like that of Neogama^ the two prominent teeth being very 
long and acute, the lower one half the length of the upper ) beyond 
the elbowed line a paler band edged without by a greyish serrated line; 
sub-marginal spots black 5 reniform pale brown in a greyish circlet; 
sub-reniform pyriform, clear brown with a black edge. 
Secondaries almost wholly black, the median band and the border 
both being very broad, leaving between them but a narrow, sinuous 
space of dark luteous; the whole base above the median band covered 
with dark brown hairs, leaving nothing of the surface of the wing 
visible ; when these are removed the luteous color re-appears \ the api¬ 
cal spot large and luteous; emarginations luteous, conspicuously cut 
with black at the tips of the nervules. 
Under side of both wings paler luteous; the apices violaceous; median 
band of secondaries narrow and sinuous, not contracted in the middle.

Catocala Serena, nov. sp. 
Expands inches. Primaries ashen-grey; transverse lines fine, 
but distinct; the basal in three equal waves, of which the costal projects 
a small tooth; the elbowed line without any prominent tooth, rather 
ragged than serrated; on the median nervure a broad sinus extending 
back to and including the sub-reniform; a sub-marginal grey serrated 
band; points black; reniform brown; sub-reniform con-colored. 
Secondaries pale-yellow; band much curved, slightly excavated with¬ 
out at the middle; after the bend sinuous, diminishing rapidly and 
terminating in a line within the hairs of the margin; border broad, 
bent in the middle, without any excavation; on the under side the 
base of both wings is fuscous and the bands and borders are broad and 
black, leaving between them but narrow spaces of yellow.
