but the black is mostly in coarse streaks containing several small tufts. The costa 
beyond the middle is blackish, with three small white spots at nearly equal dis- 
tances apart. The fringes of the fore wings, the upper side of the hind wings and 
abdomen are darker gray with a silky lustre. The under side of the hind wings 
is lighter, with darker cross-streaks or reticulations, which are much brighter to- 
wards the apex. The under side of the fore wings is dark gray, except along the. 
costal border, where the markings of the upper side are dimly reproduced. The 
legs are brown on the outside, but pale yellowish within and on the end of the 
joints. This seems to be a very variable species, and at first sight one might think 
that there were more than one species. 
One variety has the top of the head yellowish, and the oblique band and outer 
part of the wing dull whitish and slightly touched with yellowish. Another va- 
riety is quite dark, and has a broad bright ochre yellow band through the middle 
of the fore wing, from the base to the apex. 
A third variety, in very poor condition and bred on white spruce in Ashland, Me., 
has the head white and the basal part of the fore wings white with only slight traces 
of the black tufts and markings. Expanse of wings, 14™™ (Fernald). 
THE FIR TORTRIX. 
(Tortrix packardiana, n. sp., Fernald.) 
This moth was bred from the fir on Peaks Island, Casco Bay, Maine, 
and sent to Professor Fernald, who regarded it as new and sent us the 
following description: 
Head whitish; palpi and thorax ashy gray; fore wings with a whitish ground 
color, and marked with black, which is more or less overlaid with pale bluish or 
whitish scales. The black basal patch has an obtuse angle pointing out on the mid- 
dle of the wings. An oblique black band broken in the cell crosses the middle of the 
wing. A black patch rests on the costa before the apex, marked with one or two 
white costal spots ; a similarly colored patch within and above the anal angle, and 
still another on the outer border inclosing the apex, sends in a square projection to- 
wards the end of the cell. All the black markings are overlaid more or less with 
white scales, and the white portions of the wings are somewhat stained with gray. 
The fringes are dark smoky brown. 
The hind wings and abdomen above are ashy gray. Fringes lighter. Under side 
of the fore wings ashy gray, with the white costal marks reproduced. Under side of 
the hind wings whitish, irrorate with gray. Expanse of wings, 16-18™™, 
Bred from Fir by Dr. A. S. Packard, for whom I name this species in 
recognition of his extensive and valuable work on North American in- 
sects. 
THE RED SPRUCE BUD-WORM. 
(Gelechia obliquistrigella Chambers.) 
[Plate I, Fig. 2.] 
Associated with the preceding bud-worm occurred in abundance, both 
on the terminal shoots of the spruce and fir, a little reddish cylindri- 
cal caterpillar, about two-thirds as large as the larva of Teras variana, 
and very active inits habits. Itoceurred as early as the 10th of June, 
but it disappeared earlier than the caterpillar of Teras variana, and 
the moths, which were common, flying in spruce at and soon after the 
middle of July, were not seen after the first week in August.
