xxxix, p. 249) that, if iisod, Teitigoniella must fall before Cicadella 

 (Latr. 1817). 



Cicadella, Latr., is equivalent to the Cicadas ranatro}, Linn., 

 including a number o£ •uell-known insects, but not C. viridis, 

 which is placed in another section and therefore cannot possibly 

 be taken as the type of Cicadella, Latr., which name may, how- 

 ever, be used for any species placed by Linnaeus in his section 

 {supra) which may require a generic name. Kirkaldy's second 

 proposition is therefore as untenable as his first, and Jacobi's 

 substituted name clears the medley. 



In looking into this unnecessarily complicated question I have 

 been assisted by the bibliographical erudition of Mr. AV. F. Kirby, 

 and the above conclusions maj^ be accepted as representing the 

 views of both of us.
