 Division CiCADAElA (ante, p. 320). 



Since publishing my remarks on tliis division, a consider- 

 able quantity o£ fresh material has reached my hands^ and to 

 make the Cicadaria intelligible the generic analysis must be 

 continued. 



Stal (CEfv. Vet.-Ak. Forh. 1870, p. 714) proposed some 

 subgenera, but on characters which, I venture to think, are 

 insufficient and o£ a transient character. Thus his " nodo 

 apicali scutelli/^ which I lake to be the cruciform elevation at 

 the base of themesonotum,is described as typical of Chremisdca 

 in being " transverse, convexo.'''' But this, though charac- 

 teristic of the species he refers to, is not constant in tlie larger 

 generic purview to which 1 am inclined, and the same remarks 

 apply to the characters on which his subgenus Dice.roprocta 

 is founded. Had Stal subsequently revised the wliole family 

 with the skilled acumen displayed in his ' Enumeratio 

 Hemipterorum,' there is a great probability that he would 

 have shared these views.
