In 1905* Kirkaldy changes this name on account of preoccupation to 

 Motschulskyia. Conometopus Motsch. is preoccupied by Conometopus 

 Blanchardt in the Orthoptera. 



The position of this genus is uncertain; it may be an equivalent of 

 Heliona Melichar, 1903. Which see. 



1866. COMPSUS. Fieber, F. X. Neue gattungen. Verh. K-K. Zool.- 

 Bot. Gesell. AVien 16, 1866, p. 507, PI. VII, fig. 22. 



In this paper Fieber describes 8 groups of Typhlocybidae as new genera 

 and lists from one to three species in each. These must be considered 

 therefore merely as illustrations of the genera, the author having no in- 

 tention of designating definite types. In case only one species is men- 

 tioned however this becomes the type by reason of being the only origin- 

 ally included species. 



For Compsus the illustrations given are C. [icada] elegantula Zetterstedt, 

 C. discicollis Herrich-Schjiffer and C. albostriella Fallen. C. elegantula 

 is considered a synonym and C. discicollis a variety of alboslriella, hence 

 Compsus is fortuitously monobasic and the type species is alboslriella 

 Fallen, 1826. t 



In 1872, Fieber having found the name Compsus preoccupied, § proposed 11 

 in its place Alebra. 



1866. ERYTHRIA. Fieber, F. X. Neue gattungen Verh. K.-K. Zool.- 

 Bot. Gesell, Wien 16, 1866, p. 507, PI. VII, fig. 23. 



Monobasic: C. [icada] aureola Fallen,! the only species included. 



In 1872 Fieber places** Erythria as a synonym of Notus, an invalid 

 action as it has page priority over the latter name. Puton considersit it 

 a synonym of Dikraneura, an action supported by Gillette. J J

 Gesell. Wien. 16, 1866, pp. 507-8, PI. VII, fig. 24. 



The species given as examples of this group are [Cicada] flavipennis 

 Zetterstedt and its synonym C orichalcea Dahlbaum, and T. [yphlocyba] 

 forcipata Flor. 



This group is considered synonymous with Dikraneura Hardy. §§
