PSYCHE.
ON THE GENUS CICADULA, ZETT
BY CHARLES WILLIAM WOODWORTH, FAYETTEVILLE, ARK. In the second part of Mr. James Ed-
wards' excellent "Synopsis of British
Homoptera" (Trans. Ent. Soc. Lond.,
1888, ~ p . 13-108, pi. 31 it will be seen that the old genus Cicadulu has been
entirely suppressed as it seems without
due consideration.
Zetterstedt in his "Insecta Ltipponica"
(1840) divided the jassidae of that
region into four genera as follows ; Jas- sits corresponding exactly with Mr.
Edwards' family byUzosco$idae, Cicada
equivalent to Deltoce-fihal.us of later
authors, Thamnotettix including the
species now placed in the two genera
Thamnotettix and Athysanus and Ci-
cadula which corresponds to Limno-
tettix, Gnathodus and the typhlocybmi.
Cicadula was originally divided by
Zettersteclt into eight sections which
correspond to modern genera as follows : a. Ì Limnotettix.
b. r Kybos.
c. = Gnathodus.
il. = Alebra and Dicroneiira.
e. f. h. = Eupteryx.
.
g. ==: Typhlocyba.
The separation of the jassini from
the typhloybini was, natftrally, the first act of subsequent authors, accordingly
Boheman (Nya Sven. Homop. 1845)
restricted the jassini to Thamnotettix
and called the rest Typhlocyba. In the
same way did Flor (Die Rhynch. Livl.
1861) and Kirschbaum (Cic;idinen
Gegencl WiesbaJen 1868) but they sub-
stituted Jassus for Thamnotettix.
Marshall (Ent. Mo. Mag. v. 3, 1866)
divided them in a similar way but he
preferred the name Eufteryx Curtis to
Typhlocyba Germ., and the former
really had p~ioiity. In 1866 Stil
(Hen-lip. Afric:ina, pt. 4, p. 119) pointed out that Jassus was not applicable for
Eiiiopean species so it became neces-
sary to make some other disposition for
them.
This was un opportune time for the
dismembei merit of the old polj mor-
pho~is groups and the formation of more
restricted gener.1, accordingly Fieber
undertook this task and in 1866 his
'Neue Gattiingen und Arten in Homop-
tera" appeared. In this work the char-
acters used for the separation of the
genera were often insufficient so that
many more genera were formed than
the facts allowed. Fieber himself soon
recognized this and in later works
(Katalog Cicadinen 1872 and Cicadines
(1' Europe 1876) tried to rectify, as far as possible, Ins mistakes. He believed
that Cicadula should be used for a genus of Jassids, and not of Ty$hZocybids,
so he made it one of the four genela into which he divided this portion of the old genusJassus. Two of these genera he
made synonyms in a later woik but here

he made the mistake of placing one
species in Thamnotettix; with this ex-
ception Fieber places all the species of the old genus Cicadula in Cicadula,
Gdodzts and the various genera of the
tyfl locybini.
In 1871 J. Sahlberg (Not. Fen.) dif-
fers from Fieber in this assignment of
the genus Cicadula and apparently be-
cause the larger number of the species
of Zetterstedt's genus were typhlocybini he thought that the restricted genus
Cicadala should be of that group, so
he chose the first species belonging to
it as the type, thus sinking Fieber's ge- nus Kybos-a proceeding entirely un-
warranted and at variance with all rules of nomenclature. Not only did he do
this but he also erected a new genus for the true Jassids, notwithstanding that
at least two of Fieber's genera had
priority over it.
The English hernipterologists, Doug-
lass and Scott (Ent. Mo. Mag. v. II),
and Edwards never countenanced the
suppression of Kybos but have failed to
notice the manner in which Sahlbesg
substituted his own name Limnotettix
for the time honored Cicadula.
I hold, therefore, that Cicadula is
the proper name of the genus now
called Limnotettix and that quadrino-
tata Fabr., must be considered its type. The following is, I think, the correct
assignment of Zetterstedt's species.
a. I. quadrinotata Fabr.
2. strigipes Zett.
3. maculipes Zett.
4. sexnotata Fll.
5. alpina Zett.

8. s~ilphurella Zett.
b. 9. smaragdula Fall.
