THE CANADIAN" ENTOMOLOGIST, 1S3 



Argyromiges Morrisella Fitch, and A. Uhlerella I consider, as already 

 stated, to be only varieties or worn specimens of Lithocolleiis robiniella 

 Clem., a variety of which, as Dr. Clemens states, mines the leaves of a 

 species of Lespedeza. 



2. Argyromiges ( 'Lithocolleiis) Ostensackenella Fitch (Rep. j, sec. JJJ), 

 is no doubt a good species, and from Dr. Fitch's description, must 

 resemble L. ambrosiceella, ante. Larval history unknown. 



3. L. Fitchella Clem. Argyromiges quercifoliella Fitch. 



Pale saffron ; 5 costal and 2 dorsal streaks and an apical spot, but no 

 basal streak. Head and thorax white. It seems to resemble L. argentino- 

 tella in the arrangement of the costal and dorsal streaks, and it mines the 

 upper surface of White Oak leaves. Larva cylindrical. 



At p. 54, ante, it is stated that Dr. Fitch has described 7 species; but 

 there was an error in the count. The true number is 6, and that includes' 

 his Anacampsis robiniella, Argyromiges querci-albella, A. Uhlerella. and 

 A. Aforrisella, none of which can be considered good species. There only 

 remains, therefore, his L. Ostensaekenella and L. Fitchella. 



4. L. aeriferella (Hem. Larva cylindrical, and mines Oak leaves. 

 Imago reddish-saffron with 4 costal and 3 dorsal streaks, an apical spot 

 but no basal streak. The first thin costal and the first dorsal sreak inter- 

 nally dark-margined : the second dorsal dark-mar.oined by a line curved 

 above. 



5. L. obstrictella Clem. Larva cylindrical, and makes a tent mine on 

 the under side of Oak leaves. Reddish orange with three silvery fascia: 

 dark-margined externally. An apical spot, but no basal streak. 



6. L. tubiferella Clem. The larva and mine have been already de- 

 scribed. It mines the upper surface of Oak leaves. It is pale saffron 

 with slightly oblique white fascia: both dark- -margined externally ; no apical 

 spot, nor basal streak. 



The following species are named and described by Dr. Packard {Guide 

 p. 353), and I am unacquainted with these except from his descriptions, 

 which are necessarily brief. He gives no account of their structure, but 

 all of the three species, differ so widely in the habits of the larvae and pupae 

 and in the ornamentation of the imagines, as to suggest great doubts 

 whether there are not correlated structural differences which separate them 

 from Lithocolleiis pupa:. 



7. L. geminatella Packard, is said to be dark slate gray without pro- 

 minent markings, but with a round black 'spot on the middle of the dorsal
