THE PINE LEAF-MINER. 793 
the leaves are shortened, the larva feeding upon one after another only at the end, 
thus shortening them gradually until the larva is fully grown, when there are some- 
times one or more of the leaves left untouched. Those first attacked gradually become 
dry and yellow, loosening from their bases, and are ouly held in place by the green 
ones. 
The full-grown larva is three-eighths of an inch long, of a yellowish green color, 
with dark or blackish head and olive-green thoracic plate. 
The moths emerged from the 26th of December to the 30th of January, and have 
the head, thorax, and fore wings of a dull rust-red color, with two oblique paler 
bands, one a little before the middle, the other beyond, parallel to it, crossing the 
fore wings. Hind wings and upper side of the abdomen silky gray. Expanse of 
wings, half an inch. 
These moths are not easily disturbed, and if the branches upon which they are 
sitting be shaken they drop to the ground, feigning death, not even moving when 
touched. 
Specimens were sent to Professor Fernald for determination, who replied as fol- 
lows : 
" This species has been determined for me by Professor Zeller as Tortrix politana 
Haw. It feeds here on white pine as you describe, but Wilkinson gives Myrica gale 
as the food plant in England, and Heinemann gives Ranunculus acris and Centaurea 
jacea as food plants in Germany. If our species is really identical with the European 
T. politana it must be very polyphagus." 
He further says : 
" I am not able to learn that it everhas been observed feeding upon any of the Coni- 
fers in Europe." 
As Professor Fernald thinks there is still a chance that this is not identical with 
the European Tortrix politana Haw., he has prepared the following description ior 
this report: 
Imago of Tortrix (Lophodei-us) politana Haw. — Alar expanse, 13-14 mm . Head, palpi, 
thorax above, and upper side of forewings, yellowish-red. Thoracic tuft, basal patch, 
oblique and apical bands dark rust-red. The space between the basal patch and 
central oblique band is narrow, scarcely lighter than the basal patch, and indicated 
by a lighter edging on each side of the space which begins at the basal third of the 
costa and extends obliquely across the wing to the middle of the hinder margin. 
The space beyond the central band is similar to the last, beginning near the outer 
third of the costa and extending obliquely across the wing to the anal angle. The 
outer margin in some specimens is of the same color as the interspaces, and the costa 
is more or less flecked with light yellow. Fringe yellowish, with grayish scales at 
the anal angle. Hind wings and abdomen above, silky gray or slate color; under 
side and fringes lighter. Under side of fore wings light fuscous, with lighter yellow- 
ish diffused spots along the costa and outer border. Under side of abdomen and 
thorax light straw yellow, as are also the legs. Fore and middle legs annulated with 
brown.

" For several years the leaves of the common pitch pine (Pimtsrigida) 
in the vicinity of Ithaca, N. Y., have been seen to be extensively mined 
by the larva3 of a Tineid, the life history of which we have first studied 
the present season. The end of the leaf, and in many cases the entire
