CICADELLINAE : PART I. PROCONIINI 141 



mesal margin. Style elongate, extending posteriorly much beyond apex 

 of connective, without preapical lobe, apex with a mesal angle. Con- 

 nective with four arms, the posterior pair widely divergent. Aedeagus 

 asymmetrical, curved very slightly dorsally, apex with a pair of asym- 

 metrical processes. Paraphyses absent. 



Female unknown. 



Catorthorrhinus is known only from the type-species, which is known 

 only from Panama and Costa Rica. It is very closely related to 

 Ichthyobelus, differing in the characters mentioned in the key and 

 in the above description. The type-species is poorly represented in 

 collections, specimens having been seen only in BM, MMB, and NCS. 



The genitalia of the male lectotype of the type-species agree with 

 the illustrations in figure 131.

Length 14—16 mm. 



Head with crown moderately to well produced with an apical 

 process which extends anterodorsally, ocelli much closer to posterior 

 margin than to apex, located on a line between anterior angles of 

 eyes and each either equidistant between midline and adjacent anterior 

 eye angle or slightly closer to latter, without an M -shaped elevation 

 bordering posterior margin, without a longitudinal carina laterad of 

 each ocellus, without a median fovea, surface with fine pubescence; 

 antennal ledges in lateral aspect each with a longitudinal fovea, in 

 lateral aspect carinate dorsally, anterior margin steeply declivous; 

 clypeus strongly convex or depressed medially, muscle impressions 

 distinct; face finely pubescent; clypellus produced and angulate, in 

 profile with its lower portion at right angle to contour of clypeus. 



Thorax with pronotal width greater or less than transocular width 

 of head, lateral margins subparallel or slightly convergent anteriorly, 

 surface punctate, with fine pubescence, posterior margin concave, 

 with or without dorsopleural carinae which are arched ventrally at 

 midlength when present; scutellum striate or not on posterior portion. 

 Forewing brachypterous, without a membrane, strongly coriaceous, 

 venation obscure, with a few elevated rugosities, at rest extending 

 posteriorly to base of abdominal tergum VI; or macropterous with
