pupate under the edge of the leaf turned down. * * * I have 

 never found it feeding on haw leaves. * * * It may be found 

 in all stages through the summer and fall." 



In the "Cincinnati Quarterly Journal of Science" (Vol. II., p. 

 301), Mr. Chambers, writing of the lineidae found in the far 

 West, mentions having collected the mines of Ornix prunivorella 

 in the leaves of wild cherry on the mountains, "both on Clear 

 Creek, at Spanish Bar, and on Fontaine qui Bouille, near Manitou; 

 altitude, 8,000 feet." 



In the Bulletin of the U. S. Geological Survey, (Vol. III., p. 

 133), the same writer, in an article on the "Tineina of Colorado," 

 remarks that this species is "found mining the leaves of the wild 

 cherry in the mountains up at least to 8,000 feet altitude." Later 

 in the same article, (p. 141), in enumerating the localities from 

 which the species treated have been previously reported, he in- 

 cludes O. prunivorella in a list of seven species which have only 

 been found in Colorado and in latitude 35° to 40° in the Missis- 

 sippi Valley. 



In an article on the "Food-plants of Tineina," published in the 

 same connection, Mr. Chambers mentions (p. Ill) this species as 

 feeding upon wild cherry {Cerasiis seroHna), 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 Lithocollciis 

 geminatella is not mentioned. 



In 1882, Lord Walsingham, the eminent English authority on 

 microlepidoptera, published in the Transactions of the American 

 Entomological Society (Vol. X., p. 194), some "Notes on Tineidae 

 of North America." This paper was the result of a study of sev- 

 eral American collections of these moths that had been sent him, 

 many of the specimens being types of American species. On page 

 194, in speaking of certain of these specimens, he says: 



"I think these may be Ornix prunivorella, Cham., although that 

 author does not record that the larva of that species feeds on 

 apple or pear. These specimens are not in good condition, and it 

 is impossible, in so difficult a genus as Ornix, to be quite certain 

 to what species they belong. 



"They are the types of LithocolleUs geminatella, Packard, ac- 

 cording to the label attached to the second specimen^ but they 

 undoubtedly belong to the genus Ornix." 



From the statement just quoted, to the effect that Chambers 

 does not record that the larva of O. prunivorella feeds on apple, 

 it is evident that Lord Walsingham had been misled bj the omis- 

 sion in the list of food plants noted above. 



And finally the life history of the species is elaborately dis- 

 cussed, under the name Ornix prunivorella, by Mr. A. E. Brunn 

 in the Second Eeport of the Cornell University Experiment 

 I Station (pp. 151-154; PI. V.). This author applies to the
