There are several such cases in our present classification. 

 Miss I'raun's treatment of the Lithocollctis group is a case in 

 point, but a very striking example is the super family CYCNO- 

 DIOIDEA, mentioned above (p. 92), which has been classed as a 

 part of the family Elachistidae. The discovery of the 9-veined 

 genera throws an entirely new light over the group and proves 

 that it has really nothing whatever to do with the forms with 

 which it has hitherto been associated and to which it is embar- 

 rassingly alike in structure. 



Lithocollctis ostensackenella Fitch (ornatclla Chambers). 

 Miss Braun has included this in the cylindrical-larva group, 

 to which the pattern of the imago would refer it, but the larva 

 plainly separates it therefrom and the making of the cocoon 

 outside of the mine is heterogenical to both groups. The species 

 is probably best referred temporarily to the genus Leucanthiza 

 Clemens, to which it is clearly closely related, in spite of the 

 slight difference in venation. 



Gracilaria elotella, new species. 



Labial palpi white, second joint dark fuscous exteriorly; maxillary 

 palpi white on the inner side, fuscous exteriorly. Antennae white, an- 

 nulated with brown. Face, head, and thorax shining silvery white. Fore 

 wing white with golden-brown and black markings ; at the base of the 

 wing is a brown costal spot ; on the middle of the wing is a golden- 

 brown transverse fascia, broader on the costal edge than on the dorsal 

 and edged posteriorly by a sharp black, somewhat angulated line ; at 

 apical third is an outwardly strongly oblique fascia attenuated towards 

 dorsum and edged posteriorly with black and a similar fascia also edged 

 with black, but hardly so oblique is situated between this and the tip 

 of the wing. Across the cilia and the extreme tip of the wing is a 

 transverse streak of mixed brown and black. Fore and middle legs 

 with swollen black femora and white tarsi. Hind legs white, shaded 

 externally with brown ; tibia? smooth. 



Altar expanse : 6 to 7 mm.

Nearest to Gracilaria fnlyidclla Clemens, from which it 

 differs by the white basal half of the fore wings, broken only 

 by the costal basal spot.
