P. malus, but omits it from the lists of those affecting Prunus and 
Eubus, giving under the three species of the latter, Tischeria 
CBT 16 G from which we may conclude that he had changed his 
opinion about the identity of the forms found upon Pyius and 
Eubus, and had decided to consider them as distinct species. 1. 
roseticola is also given in this list as feeding on various species 
of rose”. • 
In his “Index to the Described Tineina of the United State.o and 
Canada,” published in the same volume as the paper last mentioned, 
Mr. Chambers gives these three species under their separate names, 
and does not treat them as synonyms. 
Finally, in 1883, Mr. A. E. Brunn published, in the Second Re¬ 
port of the Cornell University Experiment Station (pp. 150-15/), an 
article on the “Tineidae Infesting Apple-trees at Ithaca,. m wine i 
he gives an excellent account of the life history and habits of this 
insect (under the common name of the Trumpet Mine of the 
Apple), together with illustrations of the mine, larva, and imago. 
Mr. Brunn states that this species is the “most abundant of the 
Tineidae infesting the apple-trees at Ithaca, nevertheless it is not 
abundant enough to do them any material injuiy. 
Of the mine and its inhabitant Mr. Brunn writes as follows: 
“The mine, (see PI. YI,, Fig. la,) commencing in a glistening 
spot where the egg was laid, continues for a short distance as a 
narrow line, gradually growing wider, and then suddenly broadening 
out into an irregular expanded portion or ‘body of the mine, the whole 
having a trumpet-shaped appearance. The color of the mine on the 
upper surface is usually some shade of brown, although I have some¬ 
times observed it to be dirty white. From the under suiface of the 
leaf the mine would hardly be observed unless held, up towards the 
light or examined closely, when the mined portion of the leaf 
would be seen to be of a lighter shade of green than the lost. 
The linear portion of the mine on the . upper surface is crossed by 
crescent-shaped patches of white, which in many cases aie con¬ 
tinued for a short distance into the body of the mine. Often the 
miner after commencing the body of the mine will turn and eat 
around the linear portion, obliterating that part and causing the 
mine to appear like a blotch mine. In such cases the white cres¬ 
cent-shaped patches will be found somewhere in the body of the 
mine, indicating the position of the linear portion. These white 
markings are, however, wanting in some instances; but as the coioi 
of the linear portion of the mine is a little darker brown than the 
rest, we can still tell where the mine commenced. The position of 
the mine on the leaf is variable, it may be along the edge of the 
leaf causing it to curl over at that point, or along the midub, or 
else between these points. As the leaf dries the mine assumes a 
tentiform shape. , 
* * * “If any foreign body is brought into contact with the 
long hairs covering the larva, it will be observed to support itself 
by some of its middle segments and rapidly vibrate the rest of . the 
body,—this probably being the only way to frighten ofr parasites.
