CICADELLINAE : PART I. PROCONIINI 211 



Striate on its posterior portion. Posterior femoral setal formula 2:0:0. 

 Male pygofer in lateral aspect very broad, ventral process shorter than 

 in most other species of genus; plates not extending as far posteriorly 

 as apex of pygofer; style extending posteriorly slightly farther than 

 apex of connective, rounded apically; connective Y-shaped with 

 median keel on apical half of stem; aedeagus slightly asymmetrical, 

 with pair of short convergent processes and pair of mvich longer proc- 

 esses which in lateral aspect exceed apex of shaft. Other structural 

 characters as in generic description. Color not distinctive. 



Holotype male, Hacienda Pehlke, Colombia (E. Pehlke), 1921, and 

 eight topotypic females (IZP); one female topotype (NCS). The type 

 series had been determined as P. contraria (Walker). 



This species is closely related to P. contraria (Walker) but has the 

 posterior pygofer margin more convex, and has neither pair of 

 aedeagal processes curved mesally in caudoventral view. 



46. Genus DICHROPHLEPS Stal 



Figures 199-206 



Dichrophleps Stil, 1869a:62. Type-species: Cicada aurea Fabricius, by monotypy. 



Length 11.3-17.7 mm. 



Head with median length equal to or slightly less than interocular 

 width and from one-half to two-thirds transocular width, anterior 

 margin varying from broadly to sharply rounded in dorsal aspect, 

 without a carina at transition from crown to face, ocelli located on or 

 slightly before a line between anterior eye angles, each usually equi- 

 distant from adjacent eye angle and median line, with or without an 

 M -shaped elevation bordering posterior margin, nearly always with a 

 shallow narrow partial median fovea; antennal ledges each with a 

 longitudinal fovea, carinate dorsally in lateral aspect, with anterior 

 margin oblique; clypeus convex, muscle impressions distinct; other 

 characters as in Phera. 



Thorax with lower marginal area of proepimeron not depressed, 

 posterior portion of scutellum with or without striations; otherwise as 

 in Phera. Forewing variable interspecifically, costal margin and narrow 

 area at bases of anteapical cells always sclerotized, remainder usually 

 hyaline, occasionally suffused with amber from wing base to base of 

 anteapical cells, without sculpturing, claval veins fused almost through- 

 out their length, usually separate for a very short distance at base and 

 apex, occasionally not separate at apex; other characters as in Phera. 

 Hindwing as in Phera. Legs with anterior tibiae very slightly dilated 

 apically; posterior femoral setal formula 2:1:1 or 2:1:1:1; first pos- 

 terior tarsomere with length almost always greater than combined
