CICADELLINAE : PART I. PROCONIINI 137 



Female abdominal sternum VII strongly trilobate. 



A number of specimens belonging to this genus have been examined 

 from the upper Amazon valley and tributaries from Peru and Bolivia. 

 There appears to be a considerable amount of variation in the form 

 of the aedeagus. Ichthyobehis is closely related to Catorthorrhinus in the 

 treatment of which distinguishing characters are stated.

Length 14 mm. Head with anterior process spoon-shaped, much 

 broader than in /. bellicosus Melichar. Posterior femoral setal formula 

 2:1:0. Male pygofer without setae, produced posteriorly in a postero- 

 ventral elongate process which bears a shorter process at about mid- 

 length, aedeagus quite short and very broad, with a pair of ventral 

 recurved processes at midlength, without apical processes. Anal tube 

 with a ventral, rounded process on each side. Color dull yellow, with 

 median and lateral margins of head process, two transverse stripes 

 across pronotum, four transverse wing stripes attaining commissural 

 inargin, and a few additional markings on forewings, brown to black; 

 these additional markings of forewings delimiting a pair of spots on 

 corium opposite claval apex, and an elongate transverse marking 

 before the anteapical cells, all three of which are yellow; face with a 

 conspicuous dark spot in middle of clypeus.
