ON THE SYNONYMY OF THE APPLE-LEAF CREASER, ORNIX 
GEMINATELLA (Packard).—Having lately had occasion to study 
the Tineide infesting apple leaves in Illinois, I have been puzzled 
over the proper name of a common species which inhabits a tent- 
shaped mine on the under leaf-surface. Tt is the insect that Mr. 
. E. Brunn has discussed? as Ornix prunivorella Chambers, but 
which I believe to be the same as Packard’s Lithocolletis gemina- 
tella. The agreement of my specimens of the various stages of the 
insect, with the descriptions of these species as given by Packard, 
ambers and Brunn, led to a careful examination of the literature 
treating of the two species, the results of which I briefly summa-. 
rize below. The subject is more fully discussed in a paper to be 
sta ai in the Fifteenth Report of the State Entomologist of 
inois. 
The various stages of Lithocolletis geminatella were described and 
figured by Dr. Packard in 1869.3 The description of the moth is 
rather brief, but the figure is excellent. The larva is said to be of 
a pale livid reddish color, with the head and cervical shield black ; 
and to mine the leaves of apple and pear. 
Two years later Chambers published‘ an article on the described 
species of Lithocolletis, in which he surmises that geminatella does 
not properly belong to this genus. 
In the Canadian Entomologist for March, 1873, Mr. Chambers 
published a description of Ornix prunivorella, stating that the larva 
mines the leaves of the apple and wild cherry, and giving a brie 
account of its habits. 
In an article on the Food-plants of the Tineina, published some- 
what later Mr. Chambers mentions this species as feeding on wild 
cherry, but strangely enough omits it from the list of those feeding 
upon apple, although in connection with the original description he 
remarks that “the larva mines the leaves of apple trees.” In this 
list Lithocolletis geminatella is not mentioned. 
1882 Lord Walsingham published some “Notes on the 
Tineidæ of North America.” This paper was the result of a study
