ON THE GENUS CICADULA, ZETT. 



BY CHARLES WILLIA:\r WOODWORTII, FAYETTEVII.LE, ARK. 



In the secoiul part of ]Mr. James Ed- 

 wards' excellent "Synopsis of British 

 Hoinoptera" (Trans. Ent. Soc. Lond., 

 1888, p[). 13-10S, pi. 3) it will be seen 

 that the old genus Cicaditia has been 

 entirely suppressed as it seems without 

 due consideration. 



Zetterstedt in his"lnsecta Lapponica" 

 (1S40) divided the jassidae of that 

 region into four genera as follows ; yas- 

 sus corresponding exactly with Mr. 

 Edwards' family bythoscopidae^ Cicada 

 equivaler.t to Deltocephahis of later 

 authors, Thaifi7Jotettix including the 

 species now placed in the two genera 

 Tha7nnotettix and Athysan7is and Ci- 

 cadzila which corresponds to Limno- 

 ietttx, Gtiathodus and \\\QtyphIocybiiii. 



Cicadtila was originally divided b)' 

 Zetterstedt into eight sections which 

 correspond to modern genera as follows : 



a. = Limnotettix. 



b. ^ Kybos. 



c. = Gnathodus. 



d. = Alebra and Dicroneura. 

 e. f. h. r= Eupter3'x. 



g. = Typhlocyba. 

 The separation of the jassini from 

 the typhlocvhini was, naturally, the first 

 act of subsequent authors, accordingly 

 Boheman (Nya Sven. Ilomop. 1845) 

 restricted the jassini to TJiaitinotettix 

 and called the rest Typhlocyba. In the 

 same way did Flor (Die Rhynch. Livl. 



1S61) and Kirschbaum (Cicadinen 

 Gegend Wiesbaden 1868) but they sub- 

 stituted Jassits for Thamnotettix. 

 Marshall (Ent. Mo. Mag. v. 3, 1S66) 

 divided them in a similar way but he 

 preferred the name Eiipteryx Curtis to 

 Typhlocyba Germ., and the former 

 really had priority. In 1S66 Stal 

 (Hemip. Africana,pt. 4, p. 119) pointed 

 out that yass?is was not applicable for 

 European species so it became neces- 

 sary to make some other disposition for 

 them. 



This was an opportune time for the 

 dismemberment of the old polymor- 

 phous groups and the formation of more 

 restricted genera, accordingly Fieber 

 undeitook this task and in 1866 his 

 "Neue Gattungen 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 

 d' Europe 1876) tried to rectify, as far 

 as possible, his mistakes. He believed 

 that Cicadula should be used for a genus 

 of Jassids, and not of Typhlocybids^ 

 so he made it one of the four genera into 

 which he divided this portion of the old 

 ge\\\^i,Jass^^s. Two of these genera he 

 made synonyms in a later work but here
