Figure 72. — Ciccus viridivitta (Walker) (i from specimen from ParS, Brazil; 

 others, from British Guiana) : j, male pygofer, posterior view. 



Female abdominal sternum VII with posterior margin convex each 

 side of a small median projection. 



Specimens belonging to the genus Ciccus have been examined from 

 Northern Brazil, Amazonas, French and British Guiana, Ecuador, and 

 Peru. The writer has followed Metcalf in using the nominate species 

 Cicada adspersa Fabricius as type of Ciccus. This is one of the originally 

 included species but no species was originally selected as type of the 

 genus. Amyot and Serville (1843a:572) redescribed Ciccus Latreille 

 and selected C. adspersus (Fabricius) as type. There was nothing in the 

 original description of Ciccus which prevented the use of C. adspersus as 

 type-species, but in the redescription Amyot and Serville stated that the 

 anterior tibiae of both sexes were flattened, a condition which does not 

 occur in true adspersus. Thus there are grounds for interpreting this as a 

 misdeter mined type-species, as Distant has interpreted it, and perhaps
