row, with two small indentations near anal angle. Apices and marginations, 
very broadly white. 
Thorax, gray. Abdomen, smoky drab. 
Under side with usual bands, and half the secondaries yellowish red. 
Expanse of wings, 2.85 inch. 
Virginia City, Nevada, R. H. Stretch. (Coll. Dr. Behr.) 
A very distinct species, of which the specimen in Dr. Behr’s collection is 
the only one known tome. No other species has the hook of the mesial band 
so distinct as this, and the lines of the primaries are more regular and parallel 
to each other than in any other with which I am acquainted. 
Catocala Aholibah. Strecker. (Lepid. Rhop. et Heteroc., Page 72.) 
‘Expands 3 inches. 
‘* Head and thorax above, dark brown, with scattered white and gray scales. 
Abdomen, brown. Beneath, light brownish gray. 
““Upper surface. Primaries, dark brown, frosted, and intermixed with 
white and gray; a white space adjoining the reniform, inwardly; reniform, in- 
distinct; sub-reniform, very small, white, surrounded with black, and entirely 
disconnected with the transverse posterior line. Secondaries, crimson with 
‘brownish hair at the base; median band, rather narrow and regular, and con- 
tinued to within a short distance of the abdominal margin, where it turns up- 
wards, and is lost in the brownish hair that clothes that paazt. 
‘* Under surface. Primaries, crossed by three black bands, none of which 
join or merge with each other; the spaces between the base and sub-basal 
band, and between the latter and the median band, are orange colored, inclin- 
ing a little to crimson at the interior margin; the space between the median 
and marginal bands is white; fringe, white, with black at the termination of 
the veins. Secondaries, inner two-thirds, crimson, a little paler than on 
upper side; rest, white; marginal band, tinged with gray at and near the costa; 
median band terminates about one line from the abdominal margin; slight in- 
dications of a discal crescent, connecting with the median band; fringe, 
white. 
‘* Habitation, California.’’—H. Strecker, loc. cit. 
The above description was drawn up by Mr. Strecker from a P presented to 
him by Mr, J. Behrens. The 6j', of which two specimens are in my collection, 
is smaller (2.60 inch.), the mesial band is wide, and reaches fully to the ab- 
domina! margin, while at the base of secondaries is a deep black shade formed 
by the hairs covering that region. The brown mottled shades of primaries 
are also much darker and richer, and the lines and spots more distinct. 
C, Aholibah appears to be the most common of the Pacific Coast species, 
and is found frem San Francisco to Vancouver Island, in which latter locality 
it is, as I have previously stated, quite abundant. It is by no means confined 
to the ‘* higher mountains of California,’’ as Mr. Behrens formerly imagined, 
that gentleman having recently taken a fine specimen at Saucelito, on the 
shores of our bay. I have received examples from Oregon and Washington 
Territory. 
For the purpose of comparison, I am induced to add a description of the 
Mexican species spoken of at the commencement of this paper:
