slightly, in others attaining apex of head (extending past midlength of crown 
in holotype), and posteriorly across pronotum and almost to apices of fore- 
wings at rest, abruptly and slightly broadened before posterior extremity, the 
delimiting dark pronotal borders of the vitta continuing posteriorly to include 
the basal scutellar angles and forming a zigzag vitta on each forewing to the 
apex of the latter, the hyaline costal area of each wing interrupted by at least 
one extension of the dark zigzag line towards the costal margin; face, thoracic 
pleura, and legs, yellow.

Figures 248-251 
_Parathona Melichar (1926a:330). Type-species: Cicada lyncea Fabricius (1787a:269), 
preoccupied = Cicada cayennensis Gmelin (1798a:2105), by original designation. 
Length of male 8.3-10.0 mm, of female 8.3-9.1 mm. 
Head slightly to moderately produced, median length of crown from four- 
tenths to more than two-thirds interocular width and from one-fourth to 
slightly more than four-tenths transocular width, anterior margin broadly 
rounded in dorsal view, without a carina at transition to face, ocelli located 
well behind a line between anterior eye angles, usually close to posterior 
margin of head, the relative distance from adjacent inner eye margin and me- 
dian line of crown variable interspecifically, crown with a transverse concavity 
across ocelli, surface minutely pitted anteriorly with some of the pits len- 
ticular, without setae, lateral clypeal sutures extending onto crown and 
usually attaining ocelli; antennal ledges not protuberant, in lateral view with 
anterior margins obliquely convex or rectilinear; clypeus with muscle impres- 
sions distinct or not, transclypeal suture obscure medially, clypellus not 
produced, its profile continuing profile of clypeus, apical margin concave. 
Thorax with pronotal width variable interspecifically compared with trans- 
ocular width of head, lateral margins slightly convergent anteriorly, disk 
usually transversely rugose, dorsopleural carinae complete or not, posterior 
margin concave; scutellum glabrous or rugulose behind transverse sulcus. 
Forewing varying from almost completely membranous (P. cayennensis Gmelin) 
to coriaceous except for apical membrane that includes all of apical cells (all 
other species), with veins usually distinct, with three closed anteapical cells of 
which the bases are located opposite claval apex or more basally, with four 
apical cells of which base of outermost is more proximal than base of third; 
forewings of female in rest position exceeding apex of ovipositor. Hindleg with
