LEPII^OPTERA. Linne. 



No Lepidoptera have as yet been found in the American Tertiaries, 

 excepting at Florissant. The butterflies have been described in the Eighth 

 Annual Report of the U. S. Geological Survey and the heterocerous mem- 

 bers will be discussed at another time. Here there is place only for the 

 single species accidentally figured with the Trichoptera. 



Family TINEID^E Leach. 



Tineida? are not rare in amber, Menge having in his collection sixty- 

 nine specimens, of which one was a caterpillar and two were pupae, but they 

 have not been studied. Gravenhorst also mentions a Tinea in amber, and 

 Presl describes one species. Germar long ago figured a large Ypsolophus 

 from the Rhenish brown coal, and Heyden from the same beds figures the 

 larval mine of a Nepticula. Finally, Kawall described a Tineites from 

 " Bergkrystall " at Ufalei in Siberia. The single species here found may 

 be referred, at least provisionally, to Psecadia, and though smaller than 

 Gennar's Ypsolophus, is a large insect (for this family), resembles it not a 

 little, belongs to the same group, and is remarkably preserved. 



PSECADIA Hiibner. 



To this group I temporarily refer a remarkably well preserved moth, 

 which may very properly be better relegated to a distinct genus, on 

 account, in part, of the brevity of the first antennal joint. Its close rela- 

 tionship to Psecadia and Depressaria can hardly be contested, though the 

 neuration can not be traced. It is a large tineid, like those of these two 

 groups, and it is tolerably plain that Germar's Ypsolophus insignis is nearly 

 related ; an interesting fact, since the single fossil species of Tineidse 

 fairly known in Europe is thus found to be closely related to the single 

 species known in America.
