NOTES ON THE ACRTDIDAE OF NEW ENGLAND.-11.- TRYX- AL1NAE.- 111.
BY AT,BERT P. MORSE, WBLT,ESLEY, MASS.
Pseudopomala brachyptera (cont.).
Habits, etc.
This peculiar locust is
not uncommon locally on the coarser
grasses found in waste lands, especially upon a species of bunch-grass (Andro-
pogon scoparius) everywhere abundant.
I have taken it also on beach-grass
at Provincetown, and upon timothy.
Though a good leaper and fairly active
it is not shy and seeks safety in
attempting to escape observation by
sidling around the grass-stems rather
than by active retreat. I once saw
a long-winged fem'iile fly several feet, proving that with the possession of,
the means came the power of flying'.
Its sluggish habits, however, in con-
nection with its linear fonn, render
it less likely to attract the attention of its enemies, and to the biologist it is
perhaps the most interesting of our
locusts on that account. It must lie
seen in the living state to have its full beauty appreciated. The singular,
almost grotesque, yet graceful f m
interests even the casual observer, and
its coloration of lilaceo~is dmb, giving it almost the appearance of being
clothed with a delicate bloom, pleases
the most fastidious eye.
I have taken young specimens at
various times in June and July and
adults from July 10 to Sept. 3. It is
likely to be met with, however, a week
earlier and some time later in the
season.
About t 50 specimens, chiefly
collected in person, are from
Frye-
burg, Me. ; Florence (S. W. Denton),
Provincetown, Slierbom, Sudhury,
Wellesley, Winchendon. and West
Chop, M. V., Mass.; Canaan, North
Haven, and Thompson, Conn. It
doubtless occurs in all of the New
England States. The long-winged
form, while not common, can scarcely
be called rare. t f , 7 9 , specimens
were taken in each case in company
with the usual form. I have also an
additional f captured by Mr. C. J.
Maynard at Newtonville, Mass., and
Mr. Scudder has one from Iowa.

According to priority, as slatcd by
Brunner himself (Revision, p.
11 8),
this name should be retained for this
genus.
The genus is out of place in
Br~~iiner's table since the apical angles of the hind femora are not produced.

Pyrgomorpha penctlpennis. Thorn-

Truxalis brevicornis. Beutendiller,
2Qi.
This species has been taken on Long
Islam1 in the near vicinity of New York
by Mr. Beutenmiiller and will very
likely be found in Conn. It will be
readily determined by the characters
given in the key. In coloration it is
very similar to DichromorpJia Gridis,
the 8 being either brown, or green
above with dark brown sides, and the
9 either brown or green with a. dusky
line along the dorsal part of the sides
of the pronotum which is continued on
the head to the eye. It is found locally in the tall grass of swamps.

Prof. Blatchley.

The systematic position of this genus
and its more important diagnostic char-
acters have been indicated in Brunner's
Revision under the name of Chloealtis
(to which the type species has crrone-
onsly been referred), and to some extent in the preceding key. The type species
is well described in T1101nas, p. 7;.

Thc chief points of interest to be
noticed here concerning this species
are those connected with its dimorphism
in form and color. There is no doubt
that the å´punctuZat form is but a case
of reversion not uncommon in the fe-
male. I have yet to see a male with leg- mina and wings reaching the end of the
hind femora, that is to say. a true @%c- tulata male, though a variation of so per cent. occurs in the length of the tegmiua, these measuring 6 to 9 mm. in length.
The tcgmina of the female are usually
8 to 10 mm. long, and of the reversional form 19 mm., but examples occur of
intermediate length, one having them
12 mm. Contrary to what is usually
stated both sexes are either green or
brown above, but brown males are only
about one-third as numerous as brown
females. Of 330 N. E. adults in my
collection 20 are -fiunch,i,Zata 9 , 5 being

This specie's i's plentiful in south-
western Ncw England in the latter half
of the season, making its appearance
late in July and continuing until late in autumn. The earliest date on which I
have captured it is Ang. 4, at which
time adults and young of both sexes
were numerous. It is found in old
pastures and mowing lands but prefers
those of a damp and lmavy character
where the herbage is green thronglmut
the season,- this is perhaps the rca-
son of its more generally prevalent
green coloration. In such situations I
have found it numerous in individuals
wherever taken. It is well protected
by its coloration and is a decidedly
sluggish insect, rarely using its wings, even when fully developed, in escaping
its pursuers. It is found throughout
Colin., in R. I., and in central ancl
southwestern Mass. It is said by
Scndder (Uistrib. Insects N. H.) to
have been taken in southern N. H., but
this seems doubtful unless it possibly
occurs there in the Connecticut Valley.
I have taken it at Palmer, Mass. ;
Wickford, R. 1. ; and in Conn. at
Thompson, Montville, New Haven,
Canaan, So. Kent, Stamford, and
Greenwich, between the dates of Aug.
4 and 30. Judging from collections
sent me by Prof. Fernalcl it is comn-nin at Ainlicrst, Mass.
NOTES ON THE TYPES OF PAPIRIUS TBXBNSIS PACK. AND DESCRIPTION OF A NEW SMZ'iVTHURUS.
BY JUSTUS WATSON FOLSOM, CAMBRIDGE, MASS. Upon examining Packard's types of P.
teaensis at the Museum of comparative
zoology, the tube containing them was
found to hold: not only fourteen specimens of a Papirius, hut also ten examples of a Smynthurus, ancl the original description of P, fexensis evidently combines the char- acters of both these species, which certainly do resemble each other superficially. It being necessary to separate the species in question, I have retained the original name for the Papirius, to which is applicable a large part of the original description, quot- ing this part below with a few supplement- ary notes, and have characterized the other species as A". $adardii, again quoting where possible. The type specimens, considering they are nearly twenty-five years old, arc well preserved, even in color.
Pai)iritis texensis Pack. Pale luteons
marbled with brown and black, head paler; a few short bristles above the mouth and on posterior dorsum; long stout hairs on vertex, anterior dorsum and sides of derites. Eyeh hl~ick. Antennae shorter than body, pale reddish brown, growing darker towards the end; segments nearly as I: f: 5.5: 3; basal segment twice as long as broad, naked;
