REHABILITATION OF PODISMA LATREILLE.
BY SAMUEL H. SCUDDER, CAMBRIDGE, MASS.
The Orthopteran genus Podisma was
proposed in a Gallic form (Podisme)
by Latreille in 1825 (Fain. nat., 415)
for short-winged Acsidians with a
prosternal spine, without specification of species. Its next use was by the same
author in 1829 (Cuvier, Regne an., v,
188) in its proper Latin form, and
the European species now known as
Pe'sotettix fedestrts and Platyphyma
g-iornae referred to it. The same two
species and these only are again referred to Podisma by Serville in 1831 (Rev.
m&h. Orth., 98-99) and to the same
as a subgenus of Acridium by the same
writer in 1839 (Hist. nat. Orth., 679-
681). Burmeister, however, in 1840
(Germ., Zeitschr. ent., ii, 51) refers
these same species and these only to a
new genus Pezotettix to which he gives
as a synonym "Podisma Latr. ex
In Burmeister's view (cf. Handb. ent.,
ii, 693; 1838) the other portion of
Latreille's genus included such species
The only other authors who had at
this time employed the term were
Briill& (Exp. MOI 6e) in 18-52 who (as
quoted by Fischer) referred to it only
species of Stethophyma and Stenobo-
thr~ts ; Hej er (Germ., Faun. Ins., fasc. 17) who in 1835 (?) employed it for
Chrysochmon dispar, Stephens who
in 1835 (Illustr., Mand., vi, 29) had
referred pedestris only to it ; and Costa who in 1836 (Faun. Reg. Nap., 43-48)
had referred to it four supposed new
species, appulum, campanum, cala-
bruin and communis, the first two of
which are now regarded as synonyms
of Acridha aegy$tium L., the third
as pi obably a Pamphagus and the last
as giornae. In view of the limitation
of the genus by Serville (if Latreille
ever intended its greater extension)
this action of BrulI6 and Costa has no
force, and hence, if the name Pezotettix can be retained at all, it must be by
regarding one of the two original

lent of some unnamed divisions. But
these species are excluded by Latreille's definition, and in his writings he has
never mentioned any other species as
appertaining to the genus than the two
first mentioned above.
other of Podisma.
So far as I can discover, the first
author to refer the two species to dis-
tinct genera was Fiebet. who in June
1853 (Lotos, iii, 119) referred giornae
to his new genus Pelecyclus, and
pedestsis to Podisma. Also in 1835,
but later, his introduction being dated

[February 1895.
November, Fischer (Orth. Eur., 369,
374) referred the former species to his
new genus Platyphyma and the latter
to Pezotettix. Fischer has been gener-
ally followed, but it is plain that Platy- phyma must give way to Pelecyclus,
which in its term must yield precedence
to Pezotettix ; of which giornae becomes the type, while pedesLris becomes the
type of Podisma. The numerous
species, therefore, which in recent
years, both in this country and in
Europe have been referred to Pezotettix
must be classed under Podisma.
The early use of the term Podisma
previous to 1853 and after 1829 (other
than we have given) also sufficiently
confirms the appropriateness of restoring Podisma for the species now generally
included in Pezotettix; for Fischer de
Waldheim in 1846 (Orth. Russ. 249-
253) used it for six species of which
the first three belong to Pezotettix
of modern writers, the next two to
Chryochraon, while the last is not sec-
ognizable. [The second species, P.
$rimnoa Motsch., has also not been
recognized by later writers but I pos-
sess specimens from diflerent places
in Transhaicalia] ; Borck in 1848
(Skand. ritv. ins. nat. hist., 87-92)
refers to it pedestris and frigida ; and finally H. Fischer himself first used it, in 1849 (15 Jnhresb. Mannh. ver.
nat., $5) for frigida. His reason for
Inter (Orth. Eur., 365, note) supplant-
ing Podisma by Pczotcttix cannot be
defended.
