which are open aad clear from costa to interior margin, and which are also orange coloured between the median 
and sub-basal, and the latter and base, are points that are so distinctive as to preclude all idea of the identity 
of our species with either of its European allies alluded to. The fact of the red on under side of primaries 
being of an entirely different tint from that of secondaries is very remarkable ; I do not believe it exists in any 
other known Catocala.

CATOCALA MARMORATA. Bd wards. 
Proc. Ent. Soc., Phil., Vol. II, p. 508, (1864). 
(PLATE IX, FIG. 6, ? 9.) 
Expands 4 inches. 
Head and thorax light grey ; abdomen is wanting in the single example so far known. 
Upper surface; primaries pale grey and white, more or less powdered with dark grey or blackish atoms, 
(and bear a superficial resemblance to those of the European C. Fraxini *); transverse lines black; beyond 
the transverse posterior line, a brown band, succeeded outwardly by another which is much narrower and 
pure white ; reniform dark, and shape not well defined ; sub-reniform joined by a line to, not formed by, a 
sinus of the transverse posterior line; fringe white. 
Secondaries scarlet of a lovely shade ; mesial band narrowed in the middle, and extends almost to the 
abdominal margin ; fringe white. 
Habitat. Yreka, California. 
A regal insect, exceeding in size all known American species; the unique type from which the annexed 
figure was drawn is in the Museum of the Am. Ent. Soc. ; its sex can not be determined, as, Unfortunately, the 
abdomen, as I before stated, is non est, but from general appearances I should suppose the example in question 
to be a • 9 . 
One can but regret that so little concerning this fine species is known ; the original description contains 
no further remarks than “from Yreka, California,” and we can only hope that time, which “at last sets all 
things even,” will enable us to receive specimens, and learn more concerning this superb insect.
