This species is perhaps the Locusts
suZphå´u?v of which Harris speaks as
occurring in September.

While most likely to be confused
with its congener if any, this locust
should be readily distinguished even by
the tyro by the characters indicated in
the Key, which are not merely specific
in value but pertain to different series in the genus. While the two species
overlap slightly in season sulphurea
has mostly disappeared at the time
xa&hof/era begins to be common.
This species varies much in color,
some specimens being almost black,
others bright reddish or yellowish
brown. The wings of younger exarn-
pies are noticeably paler in color but
the general tint of a large series is quite uniform. Sometimes the veins, and
rarely the venules of the whole disk,
are somewhat suffused with brownish.
In about one-fifth of the specimens
examined the subfrontal shoot extends
one-half of the distance to the base of
the wing. I have yet to see an orange
winged example from New England,
but in ft series collected for me at Clay City, Ill., by S. W. Denton, about one-
half of the specimens have the disk of
the wing of a deep reddish orange. It
is possible that this is a distinct race or even species but the structural differ-
ences are extremely slight.
Xattthopterh is equally common with
its congener of the spring-time and is
found in the same situations, viz., amid Parhe Ì 050-51 (ore-1903). hfp //psyche nitclub o@S-OOSO htd

grass and low bushes in barren fields
and pastures on dry, upland soil. It is
rather shy, flies readily and strongly,
and will give the collector plenty of
exercise in the warm days of September.
Its rattling stridulation is somewhat
louder than that of szd$hnrea.
My earliest captures are on July 30,
latest on Oct. 30. I have specimens
from Wellesley and vicinity, Declham
and Belmont (Maynard), Mass. ; Wick-
ford, R. I. ; Thon~pson, So. Kent,
New Haven, Greenwich and Stamford,
Conn. Scudder reports it from middle
New Hampshire, and Henshaw has
taken it on Nantucket.

This species is not likely to be mis-
taken for any other save its congener,
from which it may be readily distin-
guished by the Key. It is usually paler
in color than mtho-ptera, especially
the 9 , which is sometimes pale yellow-
ish brown. Both sexes are apt to
become darker with age. A f from
Thompson, Ct., has a large part of the
hind margin of the tegmina very pale,
contrasting strongly with the general
color, a peculiarity often seen in western species of the genus.
This very common and widely distri-
buted locust is found nearly everywhere
in dry pastures in spring and early
summer, its rattling stridulation being
one of the constant features of a ramble in such places at that season. Its flight, particulaily that of the f, is less
extended than that of xan/hoå´ptera
being often limited to a few feet but
sometimes continued for three or four
rods; its course is often circling, with an abrupt curve and a sudden drop into
the grass and bushes at the end.
Adults begin to appear about the
middle of May - my earliest capture
is the 19th; it is common in June and
early July and scattering individuals
may be found even in early September.
It is found throughout New England.
I have examined specimens from Nor-
way and Deering, Me. ; Berlin Falls
(Henshaw) and Hanover, N. H.
(Weed) ; Brattleboro, Vt. (Mre. J. B.
Powers) ; Wellesley and many towns
in its vicinity, Winchendon, Wood's

Stamford, and Thompson, Ct.
