lobate, extending posteriorly as far as pygofer apex, each with multiseriate 
macrosetae and broadly convex apically. Style extending posteriorly beyond 
apex of connective, without a preapical lobe, apex obliquely truncate. Connec- 
tive short Y-shaped; aedeagus with basal apodemes as long as shaft which ex- 
tends posterodorsally; paraphyses absent. 
Serpa Distant is known only from the type-species which occurs in Ecuador 
and Colombia. Serpa stands apart from other genera of Cicadellini in having 
strap-shaped male plates and a complete hindwing venation. 
My interpretation of Tettigonia plumbea Walker is based on an examination 
of the female lectotype. I have seen a male (BM) and a female (ZIL) which 
were determined through comparisons with drawings of the type. 
Genera of Uncertain Position 
Algothyma Melichar (1926a:343), based on a nominal species that is a nomen 
nudum, is unknown to me. 
Amalfia Melichar (1924a:199), type-species: Scaris latipennis Walker, by sub- 
sequent monotypy (Melichar, 1926a:281) is known to me only from the 
female holotype (fig 885) which was not at hand as this was written. My 
notes state that the holotype (in the BM) agrees well with the original 
description except that the head is not punctate. The species is about the 
same form and size as Ortega truncatipennis (Signoret), but has the forewings 
narrowed apically and with membranous apical cells (broad apically and with 
coriaceous apical cells in ¢runcatipennis). The claval veins are fused for some 
distance at and near their midlength (disagreeing with Melichar’s redescrip- 
tion (1926a:282)). This genus is probably in the Neiwa generic group (p. 30). 
Aspilodora Melichar (1926a:346), type-species: Tettigoniella geminatula Jacobi 
(1905c:171), by original designation and monotypy, is known to me from 
eight females from Marcapata, Peru. The specimens are from 16.1-16.7 mm 
long. Externally, the head and thorax have the appearance of an Abana 
species, in the Proconiini. In the hindlegs, the femoral setal formula is 2:1:0 
and the knees at rest do not extend as far forward as the posterior proepi- 
meral margins. The female genitalia are as follows: female abdominal sternum 
VII moderately produced, transverse apically with lateral apical edges rolled 
dorsally; with two laterosternites of which the more dorsal one is incon- 
spicuous, the more ventral one large and conspicuous, extending caudoven- 
trally and fused with its complement to form a continuous U-shaped ventral 
sternum-like plate that bears a diagonal incomplete membranous cleft on each 
side; ovipositor with second valvula toothed dorsally throughout the distance 
beyond the basal curvature, the primaries almost regularly convex and bear- 
ing minute denticles on their posterior portions, apex bluntly rounded and 
with convex anteapical dorsal and ventral denticles; pygofer with very few 
apical macrosetae. Fortunately, the females are distinctive, and will be readily 
recognized, and associated males will probably aid in establishing generic 
relationships of Aspilodora in the future. 
Betarmonia Melichar (1926a:342), based on a nominal species that is a nomen 
nudum, is unknown to me.
