upon T. malivorana is given, together with an account of the 
life history of the latter by Mr. Wier, reprinted from the “Prairie 
Farmer” for February 10, 18/2. Dr. Riley writes: “These worms bear 
so close a resemblance to each other that it is almost impossible 
to characterize them.” He says concerning the larva of T. Cin¬ 
derella: “This worm changes to a chrysalis within the fold of 1 
the leaf, lined with silk, and when about to give forth the moth 
works its way partially out at one end The chrysalis is peculiar 
from having a rounded projection in front of the head. The moth 
is a most unassuming little body, with the front wings .of a dark 
ash-gray, without a shade of any other color, the hind wings 
paler.” And of the other supposed species, T. malivorana, he 
remarks: “In habit, and in size, form, and color, it is the exact 
counterpart of the leaf-tyer just described. The chrysalis is. also 
similar; but the moth, instead of being uniformly ash-gray, is of 
a bright orange, but of exactly the same size and equally uniform 
in coloration, so that by imagining a bright, golden orange, instead 
of deep ash-gray, Figure 22, c would answer for this species.” 
In 1875 Zeller again described the orange form of the moth 
(Beitr . p. 6), the species this time receiving the name Ter as 
variolana. 
In the Report of the U. S. Geological and Geographical Survey 
for 1876 (pp. 522,523), Dr. Packard publishes the following de¬ 
tails of the form on cranberry, which he then called the “Yellow 
Cranberry Worm ( Tortrix vacciniivorana ):” “The larva draws 
the leaves together with silken threads, transforming into a pupa 
within the mass. A single larva seems to select one twig or 
bunch, and eats the parenchyma from the upper surface of the 
leaves until every leaf or twig is injured and the plant nearly as 
much destroyed as if the leaves were eaten up entirely. In this 
way each larva seems to eat the best part of about twelve leaves, 
which usually remain on the stalk, affording a shelter to the pupa,, 
which is naked, partly sticking out of the leaves.” 
Probably Dr. Packard meant that the pupa was thus exposed 
after the emergence of the moth, rather than before. At least 
this is the case with the apple-feeding specimens. 
Mr. Trouvelot, by whom the drawings for Dr. Packard’s illustra¬ 
tions were made, noticed that, like the larvae of the Hesperidae, 
as Eudamus and Tityrus, this cranberry worm sends, off the ex¬ 
crement to some distance, when it defecates. When it had built 
an imperfect cocoon it was very careful to remove the pellets of 
excrement in it by taking them with the mandibles and carrying 
them out. 
In the “Prairie Farmer” for July 15, 1876, Dr. Cyrus Thomas 
notes the receipt, from Mr. T. Hallett, Galena, Ill.,. of a letter 
stating that a green worm had been doing much injury to the 
young apple trees, causing them to change color as if singed by 
fire. In the absence of any specimens the Doctor presumes this; 
to be the present species. Mr. Wier’s article, published in the 
“Prairie Farmer” in 1872 (/. c.), is here republished.
