In many, perhaps a majority of the forms, the tegminal vena- 

 tion is scarcely visible much basal of the transverse apical veins 

 The wing-venation seems to be most primitive in Alehra, Erythro- 

 ncura representing some of tne more degraded forms. 



Little is known of their habits or metamorphoses, beyond the 

 names of the food plants etc., except in the case of Erythroneura 

 comes, which has been worked out, especially by Shngerland. 

 Judging from his figures, the nymphs differ but little in general 

 appearance from the adult. 



Cicadula Havcscens (Fabr.) has a very wide range and while 

 feeding on many shrubs and herbs in Europe, is also very des- 

 tructive to the Tea-plant in India. J. Sahlberg gives brief de- 

 scriptions in various genera. 



So far as I am aware, no Eupteryginae have previously been 

 recorded from Australia and only 26 specimens were collected 

 by Messrs. Koebele and Perkins ; these form two new genera 

 and fourteen new species, one of the latter being from the Viti 

 Isles. There are none in Hawaii. The Eupteryginae are as a 

 whole the daintiest of all the Tetigonioidea, a character well up- 

 held by those about to be described. 



The nomenclature of the genera is very confused, partly ow- 

 ing to the former persistent ignoring by European authors of 

 Eupteryx Curtis, and the subsequent arrangement by which 

 Eupteryx and its synonym Typhlocyba were kept separate. No 

 less than six names proposed were preoccupied, while the pe- 

 dants also amused themselves by altering two others. 



In Jan. 1833 (not 1832 as ustially cited), Curtis created (Ent. 

 Mag. I, 192) Eupteryx for E. picta Fabr. {^zatro punctata Goeze) 

 describing hortensis at the same time. Later in the year (before 

 Easter) Germar erected Typhlocyba with 5 species, 4 of these be- 

 longing to Eupteryx; in 1833 Burmeister described in Typhlocyba 



3 species, all of them belonging to Eupteryx, while quercus (Ger- 

 mar's 5th species) is only mentioned among 7 others as ((ferner 

 gehoerend hieher." For Typhlocyba Puton, Edwards, etc., Ery- 

 throncitra should be employed. 



In 1838 (not 1840 as usually cited) Zetterstedt erected Cica- 

 dula for 23 species; in 1866 Fieber fixed quatuor punctata Fall, and 

 fenestrata H. S. (i. e. species of Thamnotcttix) as types, but as 

 neither of these was mentioned by Zetterstedt, this application 

 is invalid. In 1871 J. Sahlberg made smaragdula the type (of the 



4 species cited by Sahlberg in his t\pical division, smaragdula 

 was the only one mentioned by Zetterstedt.) Ckcjdtda there- 

 fore, as Sahlberg states, replaces Kybos Fieber, while for Cica-
