mistake about this species somewhere." Clemens did not describe a 

 Lithoiolletis quercifotitlla ; he renamed Argi/romiges quercifotietla oF 

 Fitch, and called it Lithocolletis fitchella. The specimens before me 

 belong to the genus Tixcheria, and arc probably the same as those 

 referred to by Chambers under the name T. tinctorielln. The purple 

 zigzag lines on the nidus of the larval mine, which accompanies these 

 specimens, point to this conclusion. They approach in some respects 

 Clemens's description of the female of his Tischeria ze/lerielfa, of which 

 Chambers states that, so far as he is able to learn, there is no authentic 

 specimen now extant." In Mr. Stainton's edition of Dr. Clemens's 

 papers this is one of the few species not marked with an asterisk in the 

 Index, thus signifying that it is one of which I did not see the type in 

 the collection of the Entomological Society at Philadelphia in 1872. 

 My notes assure me that this is a mistake. I have' a memorandum, 

 made when the types were examined by me at that time, to the effect 

 that this species (T 7 . zelleriel/a) approaches very closely to T. citrinipen- 

 neltu, from which it seems probable that Clemens's type specimen still 

 exists and that my observation refers to a male. 



The American representatives of the genus Tischeria require very 

 careful study before a revision can be attempted. 



Genus LYOMETIA. 



599. Lyonetia latistrigella, sp. nov.— Head and palpi white. Antennae, 

 except the white basal joint, bronzy brown. Thorax and fore wings white, with 

 an oblique broad bronzy brown streak from the middle of the dorsal margin, 

 somewhat narrowed where it crosses the fold, thence again dilated, ending in an 

 obtuse point slightly above the middle of the wing at the commencement of the 

 apical fourth ; beyond this is a large ferruginous patch, with one dorsal and three 

 costal white streaks, internally margined with bronzy brown, and a large round 

 black apical spot, preceded by some white scales from above and beneath; dorsal 

 cilia of fore wing, abdomen, and hind wings with their cilia all bronzy brown ; 

 legs white, touched with brown at the tarsal joints. Expanse 9 millim. 



One specimen in collection of Am. Ent. Soc. Phil. 



It is not impossible that this may be a variety of the species described 

 by Dr. Packard as L. nidificansella (Guide, 354), which, as pointed out 

 by Mr. Chambers, is evidently a Lyone.tia ; but the absence of the cos- 

 tal streaks and other markings alluded to in the description lead me to 

 regard it as a distinct species. Dr. Packard's species is probably more 

 nearly allied to L. speeu/el/a, Clem.
