CICADELLINAE: PART 2. NEW WORLD CICADELLINI 603 
Thorax with pronotal width less than transocular width of head, lateral 
margins parallel, dorsopleural carinae absent; posterior margin very short, 
concave. Forewing with membrane including all of inner apical cell and all of 
remaining three apical cells except their basal portions, extending proximad 
along costal margin to base of outer anteapical cell, veins elevated, distinct, 
with three closed anteapical cells, of which base of innermost is more distal 
than bases of others, apical cells and length of female wing as in Cicadella 
Latreille. Hindleg with femoral setal formula 2:0:0, first tarsomere with length 
less than combined length of more distal tarsomeres, plantar setae as in 
Cicadella. 
Male pygofer moderately produced posteriorly and rounded apically, with a 
few very slender setae in apical half, without processes. Plates triangular, ex- 
tending posteriorly beyond pygofer apex, their apices not weakly sclerotized, 
each with a few irregularly arranged elongate microsetae. Style extending 
posteriorly as far as apex of connective, with a preapical lobe, apex obliquely 
truncate. Connective Y-shaped with stem much longer than arms. Aedeagus 
short, symmetrical, not articulated with connective, without processes. 
Paraphyses short, symmetrical, crossed, not stalked. 
Female genitalia much as described above for Draeculacephala Ball. 
I have seen specimens of Helochara from British Colombia through Califor- 
nia, Arizona, and New Mexico to Jalisco, Mexico, and from New York to 
Florida. Helochara is closely related to Carneocephala and Draeculacephala from 
both of which it may be distinguished readily by its conspicuous pits and by 
the lack of an anteapical plexus of veins in the forewings. 
The type-species is able to transmit the Pierce’s Disease pathogen. Mason 
and Yonke (1971b:114) summarized the plants from which this species has 
been collected. 
Oman has described a western U. S. A. form as Helochara delta, But I have 
Seen series within which the characters break down, and in view of this and 
the fact that the described differences were only slight, I treat this as a junior 
synonym of the type-species, the only species known to me. I have studied the 
lectotype of Tettigonia herbida Walker.
