the late Alexander Fry, also contained many South Brazilian 

 species. 



Dr. Jacobi has recently published the description of " Neue 

 Cercopiden des Andengebietes/' which comprise 41 new 

 species and some new genera, and I have again to thank 

 that able homopterist for letting me see cotypes of all but 

 five of these species.

Stal had treated the Monecphora alboatra, Walk., as a 

 synonym of the above. This is one of the few indubitable 

 errors made by that great Rhynchotist, as alboatra differs 

 in the shape of the head and the position of the ocelli from 

 the generic characters given by himself for Avernus, which 

 he founded for their reception. M. alboatra cannot there- 

 fore remain the type of the genus, which was described 

 subsequent to his visit to the British Museum. 



A. meridionabs , Jac, is an allied species (uar. ?). 



Avernus balteatus, sp. n.
