The figure given by Signoret (t. xxi. fig. 10) represents a 

 species with the apices of the tegmina rounded ; in Walker's 

 species they are truncate. 



Acrocampsa excavata.

Genus Ciccus. 

 Ciccus, Latr. Regn. Aniui. ed. ii. v. p. 221 (1829). 



Type, C. latreillei, Dist. 



Latreille gave as type for this genus the C. adspersa, Fabr. 

 Ciccus was afterwards more fully described by Amyot and 

 Serville, who employed the same species for type, and this 

 was figured by the latter writers and also by Blanchard. 

 This species, however, is not the C. adspersa, Fabr., which 

 has been accurately fixed by Stal, and is the type of his 

 genus Ccelopola. The species thus erroneously identified 

 requires a new name. 



Ciccus latreillei, n. nom.

 seems to be a distinct species.
