CICADELLINAE : PART I. PROCONIINI 27 



Length 18-20 mm. 



Head strongly produced and triangular, median length usually equal 

 to or exceeding interocular width, anterior margin varying from angulate 

 to narrowly curved in dorsal aspect, without an apical carina between 

 crown and face, ocelli located on or behind a line between anterior 

 angles of eyes, each ocellus midway between inner eye margin and mid- 

 line of crown, with or without a posterior M -shaped elevation bordering 

 posterior margin, with a narrow median fovea extending almost full 

 length of crown, without a longitudinal carina laterad of each ocellus; 

 antennal ledges not sulcate nor carinate in lateral aspect, with anterior 

 margin strongly declivous; clypeus with disc flattened or depressed, with 

 muscle impressions distinct; facial pubescence obscure or absent; 

 clypellus produced and carinate medially, contour of its lower portion 

 at right angle to profile of face. 



Thorax with pronotal width much greater than transocular width 

 of head, with lateral margins strongly convergent anteriorly, surface 

 pitted on posterior two-thirds, disc with a conspicuously elevated 

 median keel which is steeply declivous anteriorly, gradually sloping 

 posteriorly, without pubescence, posterior margins slightly concave, 

 with a complete, nearly rectilinear, distinct, dorsopleural carina on 

 each side; scutellum usually transversely striate on posterior lialf. 

 Forewing with a membrane, veins not strongly elevated, often indis- 

 tinct, clavus and corium strongly coriaceous and varying from pitted 

 to closely punctate, with more than four apical cells, with an ante- 

 apical plexus of veins on corium and with supermmierary crossveins 

 to costal margin, wing apices obliquely truncate, wings of female at 

 rest concealing apex of ovipositor. Hindwing at rest extending almost 

 as far posteriorly as forewing apex; vein R2+3 incomplete. Hindlegs 

 with femoral setal formula 2:1:1 or 4:1 :1 (see discussion below); first 

 tarsomere with length less than combined length of second and third. 



Male genitalia: Pygofer well produced, rounded, with numerous 

 dispersed microsetae and occasionally a few macrosetae on posterior 

 half, without processes. Plates separate throughout length ; not extend- 

 ing posteriorly as far as, or extending beyond pygofer apex, triangular, 

 with dispersed microsetae and occasionally interspersed macrosetae. 

 Style extending farther posteriorly than apex of connective, with 

 preapical lobe, rounded apically. Connective Y-shaped with arms 

 contiguous at anterior ends. Aedeagus with shaft very short, with 

 a pair of elongate processes arising basally and extending postero- 

 dorsally or posteriorly, very much longer than shaft. Paraphyses absent. 



Female abdominal sternum VII with posterior margin uniformly 

 shallowly concave.
