754 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
in August and September did not begin to give forth the moths in the 
breeding cages before early January, February, and March, and were 
greatly hastened without doubt by the heat of the room. On February 
15, however, a tew twigs were collected, from one of which, on Febru- 
ary 28, a full-grown larva had emerged and was found crawling about 
the cage. This would seem to indicate occasional larval hibernation. 
"As to remedies, the only one which I can suggest at present is that 
involving the somewhat arduous task of picking off' the infested twigs 
in early winter and burning them. Whether the salvation of the trees 
will be worth this labor in greatly infested regions will depend entirely 
upon their value to those interested." 
75. The pitch-pine uetinia. 
lietinia r'ujidana Fernald. 
Order Lepidoptera ; family Tohtkicid.i:. 
Inhabiting terminal shoots of Pinus rigida, and of similar habits to the Frustrating 
Retinia, a gray, brown, or blackish larva 8 mm (£ inch) in length, which in its perfect 
form becomes a small moth with dingy white wings, marked with dark red and sil- 
very gray. (Conistock.1 
"In the summer and fall of 1879 Mr. S.H.Gage, of Ithaca, N. Y., sent 
to the department specimens of the pitch-pine containing Tortricid 
larvaB and pupre, which in their work resemble Retinia frustrana, but 
differ from that insect in coloration and in being slightly larger. These 
developed into a moth intermediate in characters between R. frustrana 
and R. comstockiana, and which has been described by Prof. (J. H. 
Fernald as follows : 
The moth. — Head sordid white, with a yellowish tinge ; front and palpi inclining 
more to ashy ; antenme brown, annulated with white ; thorax above very light gray, 
washed with dull ocherous; deepening to a coppery tint on the front of the patagiae. 
Thorax beneath, abdomen, and hind wiugs above and beneath, and fore wings be- 
neath light gray with a silky luster ; fringes of the hind wings lighter, with a line 
near the base concolorous with the wings. 
Fore wings above sordid white, with a basal patch occupying the basal fourth of 
the wing, composed of about four irregular cross streaks of dark red, alternating 
with similar streaks of silvery gray, the outer red streak sending out a tooth on the 
fold. The light space following the basal patch has several small gray costal spots, 
from which light ocherous streaks extend across the wing. A dark-red band extends 
across the wing beyond the middle, divided on the costa by a geminate white spot. 
Below the cell the basal half of the red band is replaced by stripes of light ocher 
yellow and silver white; the remaining portion of the red band below the cell is 
curved outwardly, making this part convex on the outside and concave on the side 
towards the base. The apical portion of the wing is dark red, changing to bright 
ocher yellow inw r ardly, and towards the anal angle divided by a subterminal gemi- 
nate broken line of silvery scales, extending from the costa to the anal angle. Fringe 
reddish purple. The costa from the basal patch to the terminal band is marked with 
geminate white spots alternating with gray. Posterior femora and tibia} very light
