_slate colour, and the abdomen is yet paler. The entire insect, in some 
lights, shows purplish reflections. Under the lens, the iron gray colour is 
resolv ed into blackish or dark brown, mixed with ochreous and whitish 
scales. Alar ex. 1% inch. |

The larva has the head and first segment dark purplish-brown, except 
the anterior margin of the first segment, which is whitish. Remaining 
segments whitish, with two longitudinal narrow pale purplish lines on top, 
outside of which, on each side, is a wider deep purple one; there is also 
a multitude of small purple spots, from each of which graceede a hair. It 
sews together leaves of the Oak (Quercus .obtusiloba) im May, and 
‘remains in the pupa state about ten days, the imago appearing early in 
June. | 
The two preceding species and 2). obscurusella, ante, p. 100, and 2. 
bistrigella, ante, p. 92, xesemble each other very closely. 2. obscurusella 
is more ochreous than the others, and the markings assume the form 
rather of narrow irregular and zig-zag lines, although, on close inspection, 
three dark costal spots may be discovered as in gwerciella, but less dis 
tinct. 2). bicostomaculella is smaller than the others, and the three costal 
blackish spots have, in it, become to the naked eye three irregular bands, 
narrowing towards the dorsal margin. 1 have no specimen of 2. rs 
gella now before me, but I think it can be distinguished by the more 
linear shape of the ochreous streaks before the ciliae, and by the two 
small ochreous patches about the middle of the wing. 2. gwerciella may, 
however, be more readily distinguished by the thoracic tuft. | 
As the species of Depressaria described in this and the preceding 
No. differ somewhat, structurally, it is possible that some of them ought 
not, in strictness, to be placed in this genus. Yet they approach it more 
nearly than any other. The following notes will explain their similitudes 
and differences : — 
D. dubitella has the second joint of the palpi much thickened, form: 
ing a small wnadivided brush ; the superior portion of the discal vein is 
very oblique, and the superior branch is united to the subcostal at the 
end of the cell. ‘The abdomen in my single specimen is broken off. It 
does not belong strictly in Depressaria. 
D. albisparsella has the palpi of Depressaria, but the brush is very 
large; the wings in my single specimen are closed so that I cannot 
observe the neuration. The antennae are minutely but distinctly pectin: 
ated, more so than in the true Depressaria.
