wings dark brown, mixed almost equally with ochreous, and with a few 
scattered white scales. In some parts of the wings the dark brown scales 
are condensed into irregular, wavy, rather indistinct lines or narrow 
bands, one of which is placed at about the basal one-fourth of the costa, 
and is oblique and furcate, sending one of the branches nearly to the end 
of the disc ; at about the apical one-third they are again condensed into 
an indistinct zigzag line across the wing, and again into a brown irregular 
_patch at the apex. Sometimes in fresh specimens these zigzag lines and 
< 
spots in the apical part of the wing appear to be continuous ; but they are 
indistinct, and when the wing is a little rubbed, they appear as very indis- 
tinct separate lines or spots. Cilize dark fulvous, sprinkled with dark 
brown ; posterior wings pale grayish fuscous, becoming darker towards 
the tip. Alar ex. 54 inch. Kentucky. Larva unknown. Also in the 
collection of Mr. Wm. Saunders, London, Ont. 
9. D. pseudacaciella. N. sp. 
Antennæ and palpi dark purplish-brown, streaked and flecked with 
white. Head clothed with dark brown and white scales about equally, 
tinged with pale purplish. Thorax and anterior wings dark purplish- 
brown, streaked and flecked with white and ochreous especially ; a streak 
extending from the base nearly to the apex, just within the costal margin 
of which the prevailing hue is ochreous, mixed with white. A white 
costal spot at the beginning of the costal ciliæ, and an opposite dorsal 
one, both small. Ciliz grayish silvery, with a rather distinct and wide 
hinder marginal line at their base dark brown. Hind wings pale ochreous- 
brown. Body and legs dark purplish-brown, with a nearly equal inter- 
mixture of white scales. A/ar ex. nearly $ inch. Very common in 
Kentucky. 
Dr. Packard (Guide, p. 349) mentions another species, 2. robiniella, 
which seems to be very distinct from this, but which, like this, feeds upon 
the leaves of the Locust (Robinia pseudacacia). ‘The larva of this species, 
when young, inhabits the mines of Lzthocolletis robiniella, Clem., and 
L. ornatella, Mihi, in the leaves of R. pseudacacia and À. hispida. When 
older, it sews together the leaflets, and lives between them. I once saw 
one cut its way into the mines of Z. robiniella, proving thus that its 
frequent presence in those mines was not owing to its having accidentally 
wandered into torn mines. 
The young larva is green, with darker green longitudinal markings, 
with the head and next segment shining black, and mouth ferruginous.
