NOTES ON GLUPHISIA AND OTHER NOTOD0NTIDAE.-11. BY A. S. PACKARD, PROVIDENCE, R. I.
The structural differences between
G. trilirzeata and G. wrightii, var.
slossoniae, and which at first led me to think them generically distinct, are the following :
A 9. The head is remarkably small, much
more so than in G. trilineafa ; and is loosely scaled in front. The antennae are pectinated, the branches a little longer than in $
trili-
neata. The palpi are short, small, depressed, with loose scales; and they are not quite so large and long as in trilineata.
The thorax
differs from that of Glufhisia trilineata in
having a median dorsal tuft. The legs ale hairy, and much as in tnlineata, the tarsi being ringed with gray and darker scales. The fore wings are narrow but with the
costa unusually convex, much more so than in trilineata; the apex is somewhat rounded, but much as in trilineata ; the outer edge is very faintly excavated below the apex.
The
hind wings are of the same shape as in trili- neata. There are six branches of the sub- costal vein: branch I is longer than in
trilineata and ends half way between end of costal vein and end of branch 2 of the sub- costal ; the costal area is wider towards apex than in trilineata. The 5th and 6th branches are nearly as in trilineata.
The lower discal
vein is not so much bent as in the last
named species.
The three median veins are
nearly as in trilineata, but the zd median space is wider than in that genus. The
submedian vein is represented by a simple fold. In the hind wings the two branches of the subcostal are much longer than in trili- neata, the space between them being long and narrow, in trilineata short and broad triangu- lar. The discal veins are, taken together, slightly curved, where in trilineata they make a decided angle at the origin of the indepen- dent vein; and there is a common origin of the lower discal, and of the two median
veinlets. The second median interspace is much wider than in the species of the other section ofthe genus. The submedian vein is represented by a simple fold.
G WRIGHTII VAR. SLOSSOTIAE.-BO~~ and
wings pale ash-gray ; the prothoracic segment colored as the head, but the rest of the thorax is dark brown, the median thoracic tuft also dark brown. Fore wings black-brown on
basal one-fifth ; this portion sending out five sharp tooth-like projections along the sub- costal, submedian and internal veins. A
broad distinct median oblique band, with ir- regular lobulate edges, and widening on the costa; it encloses a very distinct discal ti-iar- gular white spot, the apex pointing outwards. A submarginal broken row of dark spots
arranged much as in Ghflhisia trilineata. Hind wings with no markings, but at the
inner angle is a faint short curved dark band, edged externally with white, but not reaching beyond the middle of the submedian space. Fringe concolorous with the wing, but
checkered with small black spots.
Wings beneath much as in Glu-phisia tfili- ueata; the black band is faint, its outer edge indicated on the costa by a dark spot. Ex- panse of wings, 38 inm; length of body, 15 ~n tn .

Cal. This does not seem to differ from
N. gibbosa. The $ has a paler body
and wings, the fore wing's are more
pointed,
and as in many Pacific coast
moths, it is larger than the eastern form ofgibbosa. On examining my type of
A? doubledayi in the collection of the
American entomological society I find
that it is not even a variety of gibbosa. It only differs in having the under side

52 2 PS2'TH.E'. [September 1893
of the palpi and of the fore legs dusky. OEDEMASIA PERANGULATA H. Edw
I 8. Type, Colorado. A very distinct
and good species.
OEDEMASIA SALICIS I 8. Type,
California. I also have a $ given me
some years since by Mr. Edwards. I
cannot after repeated examination really perceive any differences between this
and the eastern concinna ; it only differs in size, being a little larger, and with slightly more pointed fore wings, as
one would expect to find it, in accord-
ance with the facts pointed out in my
Monograph of Geometrid Moths (p-
587) where a list of twenty-five species of Geometrids which grow larger on the
Pacific than the Atlantic coast is given. OEDEMASIA EXIMIA Grote. I have
been unable to find any valid distinc-
tions between this and conci~zna (also
salicis) , except that the insect is larger, and the fore wings more produced
towards the apex. The females of the
normal concinna differ notably from
the males in having pale chocolate hind
wings, while in the males they are
white, with a dusky patch at the inter-
nal angle. The three above mentioned
so-called "species" also agree in having a similar distinct round discal dot.
OE. BADIA Pack. is a distinct species,
and differs from Oe. concinna in the
long linear discal spot, outside of which is a dark reddish brown shade.
There
are also distinct scalloped reddish brown lines at the base, and beyond the discal spot.
The thorax is also darker red.
OE. PERANGULATA H. Edw. Type
from Colorado.
This is a distinct, well
marked species.
On re-examining the venation and
other imaginal characters I 'am at
present unable to perceive any impor-
tant generic differences between Oede-
masia and Schizura, and probably the
species of the former will have to be
merged with those of Schizura.
SCHIZURA EDMANDSII (Pack.). This
is evidently a synonym of 5'. unicornis. The specimen ( <? ) marked edmandsii
in Mr. Edward's collection appears to
be only a small unicornis with nar-
rower wings than usual. The only
difference is in the dusky tawny costa of the fore wings, and the similarly tinted hind wings, due perhaps to imperfect
preservation.
s. CONSPECTA (H. Edw.). I 3.
Type, California.
This is only a cli-
matic variety of 27. unicornis; the posi- tion of the markings is identical in the two forms, but com$ecfa is larger, the
fore wings as much produced as in any
of zmicornis. The pale area on the
outer third of the wing is clear and
whitish, and the hind wings are clearer
and whiter than in any eastern example
of unicornis.
S. TELIFER (Grote).
Th'is is only a
variety of S. ipomeae, with two long
distinct black streaks, one passing
through the discal spot, and the other
extending along the submedian vein.
JANASSA COLORADENSIS H. Edw.
Type. 3 Q , Utah A climatic variety of
7. lignicolor. It is whiter, paler, freer from dark scales, probably due to living in a drier climate, flying over a paler
soil, under a clearer sky. Yet an individ- ual of 7. liynicolor from Georgia, in the same collection, comes very near it.
