are named? Amyot and Serville take the latter view and name 

 hcematodes as its type. The genus can, however, be much more 

 accurately recognized by the naming of plebeja in 1825 than by 

 the characters and species mentioned in 1829, and I think we 

 should accept plebeja as its type. Many recent writers ignore 

 Tibicen entirely, but this cannot be done. Either it is equivalent 

 to the Cicada of Stal with plebeja as type or Tibicina Kolen. with 

 hcematodes as type. Another question arises in studying this case. 

 Fabricius, who uses Tettigonia Geoff, in place of Cicada Linn, 

 indicates tibicen as its type, and I am not certain but we should 

 consider this a valid naming of a type for genus Cicada of Linn. 

 This, of course, would antedate Latreille's genus Tibicen and leave 

 genus Cicada as it was understood before Distant founded his genus 

 Rihana. I can find no ruling on this in the International Code, 

 and therfore for the present use Cicada for orni, largely on the 

 assumption that Linneus intended that for the type of his section 

 Manniferce, and Tibicen for plebeja. Latreille in 1810 names 

 plebeja as type of genus Cicada Linn., but as it was not an original 

 species, this is of course invalid. 



Genus Philasnus Stal. — As I understand the International 

 Rules, a variety name is preoccupied by an earlier species name in 

 the same genus. This necessitates our changing the name of 

 Philcenus leucophthalmus var. lineatus Linn, for which I now propose 

 the name fabricii; and we must also change the name of what was 

 formerly the typical spumarius of Fallen .which I propose to call 

 falieni. Both of these colour varieties occur in our fauna. 



Genus Ceresa Am. & Serv. — The name aculeata was used in 

 this genus by Fairmaire in 1846, so I now propose the name 

 stimulea for the Ceresa aculeata published by me in 1909. 



Genus Stictocephala Stal. — I cannot find that a type has 

 been named for this genus, so I now name lutea Walk as such 

 type, as it is the best known species mentioned by Stal when 

 founding the genus. 



Genus Campylenchia Stal.— I do not feel at all convinced that 

 our North American latipes Say is identical with the South American 

 curvata Fabr. and have retained it as distinct in my catalogue.
