lenticular impressions on the crown, and in all of the females dissected, the 
pygofer and abdominal sternum VII are similar to other genera of the 
_ Graphocephala generic group (above). The second valvulae of the ovipositor are 
3 quite variable interspecifically in Graphocephala, varying from a common condi- 
tion found in coccinea (fig. 686) to one in which the teeth are reduced (G. 
atropunctata (Signoret), fig. 721) or practically absent (appropinquans, fig. 712), 
: and with the apex rounded, instead of acute. The toothed area is shorter, in 
- nigrifascia (fig. 710), than in the other species studied. This degree of variation 
in the second valvulae within a single genus is very unusual in the Cicadellini. 
There is also much variation in the male genitalia, especially in the form of 
the asymmetrical paraphyses (figs. 701 and 707). Drastic reduction of these 
| structures is a notable feature within Graphocephala. The aedeagus varies also,
