THE LINDEN LEAF-ROLLER. 477 
Larva .70 inch in length, on bass wood. — Body much less hairy than the full-grown 
larva; head black, of the usual size; prothoracic segment swollen, reddish amber, 
with a transverse black thickened spot giving rise to a few long unequal whitish 
hairs. End of body with two large black spines directed straight out. Body yellow- 
ish, with pale Japan varnish-brown stripes, the dorso-median one twice as wide as 
the others. Described from forty specimens. 
The same larvos after molting, .75 inch long. — Body black, as in the fall- fed larva. 
Anal spines much stouter, less acute than before ; the body is more hairy, and in gen- 
eral much as in the full-fed larva. By August 23 all had molted and begun to feed. 
Full-fed larva on apple.— Body thick, of very uniform width, smooth, cylindrical, with 
long white hairs, those on the prothoracic segment and eighth and ninth abdominal 
segments the longest, being twice as long as the body is thick. The segments are 
thickened a little behind. Head large, considerably broader than the body, and 
shiniug black. Prothoracic shield yellow, with a short black stripe on the lower 
edge of each side. Body smooth, black, with four greenish-yellow stripes on each 
side, the stripes being about one-third as wide as the black interspace. Beneath, is 
a lateral greenish-yellow somewhat interrupted, stripe, and a median fine uninter- 
rupted greenish filiform line. Abdominal legs and base of thoracic legs livid yellow ; 
thoracic legs black. A black blotch on the sides of the abdominal legs. Length 1.40 
inches. Described from seventy-seven specimens." 
6. Pantographa limata Grote. 
In September the caterpillar of this Pyralid rolls the leaves of the 
bass-wood in a peculiar manner, as observed by Professor Fernald in 
Maine and by Miss Murtfeldt in Minnesota. As stated by Professor 
Fernald, they pupate about the middle of October, the moth in confine- 
ment emerging during the first week in November, but probably in 
nature hibernating as a pupa under the leaves, and appearing as a moth 
the succeeding spring. 
The larva cuts the leaf across from near the middle of the side, past 
the midrib nearly an inch, in the larger leaves. This cut, which is 
about an eighth of an inch wide, first starts directly across the leaf, then 
curves gradually towards the apex, then back to the former direction, 
so that the entire cut is nearly in the form of the letter S, somewhat 
straightened out. The part beyond the cut is rolled over so as to form 
a cone with the apex toward the base of the leaf, and when inclosing a 
larva both ends are turned in, so as to close the openings. In drawing 
the parts of the leaf together the larva spins the thread from side to 
side — from the side of the cone to the surface of the leaf beyond, about 
forty times in a place before moving to another. The second set of 
threads, which is from a fourth to a half an inch from the last, frequently 
draws the parts of the leaf together so much that the thread of other 
bundles hang in a loop. The larva deposits its excrement within the 
* Datana sp. — This species occurred on the linden at Brunswick, Me., August 26. 
Its larva is yellowish, the prothoracic segment being entirely yellowish, and the base 
of all the thoracic and abdominal feet with a large conspicuous yellow area ; four 
large yellow patches between the four anterior pairs of abdominal and the anal legs. 
The eight yellow stripes are rather wider than in D. angusii.
