CICADELLINAE : PART I. PROCONItNI 



51 



numerary crossveins to costal margin, Hindwing as in Homoscaria. 

 Hindlegs as in Homoscarta. 



Male genitalia: Pygofer short, obliquely truncate apically, with 

 niicrosetae on and near ventral margin, without processes. Plates 

 fused nearly throughout length, extending much farther posteriorly 

 than pygofer apex, with numei'ous dispersed microsetae. Style extending 

 farther posteriorly than connective, without preapical lobe, scarcely 

 modified apically, with a number of irregularly arranged microsetae. 

 Connective Y-shaped, stem broadened apically. Aedeagus slender, 

 symmetrical, with a pair of dorsal apical processes, genital orifice 

 terminal. Paraphyses absent. 



Figure 37. — Dictyodisca salvini (Fowler): f, apical portion only of aedeagus. 



Female abdominal sternvun VII excavated each side of a median 

 triangular posterior projection. 



Dictyodisca is known only from the type-species, of which only eleven 

 specimens are known. The observations of the male genitalia were 

 made from a teneral specimen in the British Museum (Natural History). 

 The abdomen had been glued on this specimen, and the anterior 

 dorsum was slightly damaged. 



Dictyodisca is known only from Panama and Costa Rica. It is related 

 to Homoscarta, but differs by the characters mentioned in the key and 

 in that the posterior tibial setae of rows 1 and 2 are sparse, short, and 

 stout, whereas in Homoscarta they are more closely set and more slender.
