Subfam. CiCADir^ (continued from p. 336). 

 Division Cicadakia (ante, p. 32.'). 



Since publisliin<^ my remarks on this divi.-^ion, a consider- 

 able quantity of tVeslu material has reached my hands^ and to 

 make the Cicadaria intelligible the generic analysis must be 

 continued. 



Stal ((Efv. Yet.-Ak. Forh. 1870, p. 714) proposed some 

 snb^icneia, but on characters wiiich, I venture to think, are 

 insufficient and of a transient character. Thus his " nodo 

 ajiicali scutelli," which I lake to be the cruciform elevation at 

 the baseot'theinesonotum,is described as ty[)icalof 6'^renas/ica 

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

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

 generic purview to wliich I am inclined, and the same remarks 

 apply to the characters on which his subgenus Dic/'roprocta 

 is founded. Had Sial subsequently revised the whole family 

 with the skilled acumen displayed in his ' Enumeratio 

 Hemipterorum,' there is a great probability that lie would 

 have shared these views.
