CICADELLINAE : PART I. PROCONIINI 123 



coarsely pitted, with dorsopleural carina which is strongly arched; 

 other characters as in Peltocheirus. Wings and legs as in Peltocheirus. 



Male genitalia: Pygofer moderately produced and truncate apically, 

 the posterior margin concave, with numerous dispersed microsetae on 

 posterior half of disc, without processes. Plates separate throughout 

 their length, extending farther posteriorly than pygofer apex, each 

 narrowly triangular, with numerous dispersed microsetae. Style not 

 extending as far posteriorly as apex of connective, without an anteapical 

 lobe, truncate apically. Aedeagus asymmetrical, slender, elongate, with 

 an apical median asymmetrical process and a pair of symmetrical apical 

 processes. Paraphyses absent. 



Female abdominal sternum VII with a broad submembranous apical 

 marginal area, the posterior margin convex and produced. 



Yotala is known only from the type-species, wliich occurs only in 

 Bolivia and in Mato Grosso, Brazil. It is very closely related to 

 Peltocheirus, from which it may be distinguished most readily by its 

 moderately produced pygofer with the posterior margin concave, by 

 its truncate style apices, and by its asymmetrical median aedeagal 

 process.

Figures 115-120 

 Acrocampsa StSJ, I869a:66. Type-species: Fulgora pallipes Fabricius, by mono- 

 typy. 



Length 11-14 mm. 



Head strongly produced, lateral margins concave in dorsal aspect, 

 inedian length greater than interocular width, less than transocular 

 width, anterior margin curved dorsally and carinate at apex, ocelli 

 located on or slightly behind a line between anterior angles of eyes, 

 each slightly closer to midline than to adjacent eye angle, surface with 

 fine pubescence; clypeus depressed medially, inuscle impressions 

 distinct, transclypeal suture obsolete ; other characters as in Peltocheirus. 



Thorax with pronotum not wider than head, lateral margins slightly 

 concave, posterior two-thirds of disc convexly elevated and with surface 

 punctate and occasionally rugose, with or without pubescence, with 

 complete dorsopleural carinae, each carina curved slightly downward 

 at midlength; scutellum with or without striae on posterior portion; 

 otherwise, as in Peltocheirus. Forewing with veins distinct or not, 

 occasionally elevated, clavus and corium coriaceous, punctate, with 

 four apical cells, the base of the fourth not more basal than base of 

 third; otherwise as in Peltocheirus. Hindwing and legs as in Peltocheirus. 



Male genitalia: Pygofer with ventral margins overlapping plates, 

 moderately produced, posterior margin rounded, with numerous dis-
