disconnected, not continued to the base of the wing. The apical streak 

 is rather more slender, and the black spot on the saffron-yellow space 

 between the golden bands is decidedly elongate, whereas in Uenigiella it 

 is not longer than its width. It would be interesting to learn whether 

 any species of Arundo grows where these specimens were taken. Its 

 larvae may possibly be found to have similar habits to those of lieniyiella, 

 which mine the leaves of Arundo phragmites in August and September. 

 Postponing for the present a more detailed description, I have named it 

 after my friend Professor C. H. Fernald, to whom I am greatly indebted 

 in my studies of North American Tineidae and Tortricidas, and whose 

 labors upon the latter of these two families promise to yield valuable re- 

 sults. 



1189. Cosmopteryx lespedezee, sp. nov. 



This is a beautiful new Cosmop/t-iy/x in Prof. Riley's collection, 

 labelled " Cosm .opteryx on Lespedeza, Boll." Nearly allied to ('.cle- 

 menseUa, Stn., and possibly to C. montisella, Cham.; differing from 

 clemenseUa in having the outer margin of the dark basal portion of the 

 wing more oblique, the two middle silver streaklets preceding the orange 

 band rather longer, and especially in the annulation of the antennae. ( '. 

 clemenseUa has a broad white band about T g of an inch wide at the 

 commencement of the outer third of the antenna?, preceded and fol- 

 lowed by equally wide dark bands, the apex being widely white. 



The species now before me has the wide dark band before the white 

 apex ; but this is preceded by a very narrow white band, which in its 

 turn is preceded by an equally narrow dark one. In other respects it 

 closely resembles C. clemenseUa , the orange band being pale as in this 

 species. C. montisella is described as having a dorsal and an apical 

 streak beyond the orange fascia; this species has only an apical. 



Genus BATRAfHEDRA. 



1229, 12. r IO. Batrachedra rileyi, sp. nov. — Bred from rotten cotton-bolls. 



Head chestnut-brown; palpi widely divergent, whitish, with an oblique pale 

 brown mark on each side near the end of the second joint, and two or three 

 brownish spots on the sides of the apical joint. Antenna" with white and fuscous 

 annulations: the basal joint elongate, chestnut brown. Fore wings chestnut- 

 brown, slightly shaded with fuscous towards the costal margin : a whitish oehre- 

 ous streak at the base of the dorsal margin, followed by two or three other smaller 

 ones along the dorsal margin (in some specimens these are obsolete): above the 

 dorsal margin are two oblique whitish ochreous streaks, the first before the mid- 

 dle, the second before the anal angle. A similar streak from the costal margin 

 immediately before the apex is outwardly margined by a streak of black scales, 

 the apex and apical margin being also black; there is also a faint fuscous streak 

 running downwards through the cilia below the apex. On the cell are two elon-
