CICADELLINAE : PART I. PROCONIINI 265 



Acrogonia flaveoloides, new species 



Figure 260 



Length of male 10.0 mm.; of female 11.5 mm. Head with median 

 length of crown less than transocular width, without an M -shaped 

 elevation bordering posterior margin, disc fairly concave in male, 

 less so in female, antennal ledges in lateral aspect carinate dorsally, 

 face convex medially. Pronotum as in A. terminalis, new species. Fore- 

 wing of male with corium hyaline basally and apically, with a stig- 

 malike costal spot before apical cells, of female coriaceous except for 

 membrane, which includes all apical cells, in both sexes veins elevated 

 and distinct, surface not punctate, without supernumerary veins in 

 clavus. Male genitalia as in A. terminalis but with a sharply defined 

 deep lobe on dorsal margin of pygofer and with aedeagus curved much 

 more abruptly dorsad and bifid only at tip. Ground color of crown, 

 anterior portion of pronotum, and scutellum black marked with 

 yellowish orange spots, these larger on anterior pronotal margin, 

 remainder of pronotum dull green with an orange yellow submarginal 

 longitudinal stripe on each side in male; ground color of basal portion 

 of forewings dull green; face as in A. terminalis. 



Holotype male, Rio de Janeiro, October, C. F. Baker collection; and 

 one female, same data (USNM). 



This species is very closely related to A. terminalis, of which the dis- 

 tinguishing characters have been set forth in the discussion of that 

 species (p. 261). 



Acrogonia izzardi, new species 

 Figure 248 



Length of male 10 mm.; of female 11.5 mm. Head with median 

 length of crown less than transocular width, crown of male with a 

 slightly elevated M -shaped area bordering posterior margin, disc not 

 concave in male, concave in female, antennal ledges in lateral aspect 

 carinate dorsally, clypeus flattened medially, face not pubescent. 

 Pronotum punctate, dorsopleural carinae diagonally rectilinear. 

 Forewing coriaceous with an apical membrane, veins elevated, surface 

 not punctate, without supernumerary veins in clavus. Male with 

 pygofer as in A. obscurior (Fowler) ; plates separate throughout their 

 length; style extending farther posteriorly than apex of connective, with 

 a distinct preapical lobe, apex rounded; connective short, Y-shapcd, 

 without a median keel; aedeagus with a pair of ventral retrorse proc- 

 esses near midlength; anal tube without a ventral process near mid- 

 length, with a basal sclerite which extends vcntrally and with its apex 

 directed slightly posteriorly. Female abdominal sternum VH broad,
