medially, muscle impressions not very distinct, transclypeal suture obsolete 
medially, clypellus tumid at midlength, otherwise with its contour continuing 
profile of clypeus, not pubescent. 
Thorax with pronotal width slightly greater than transocular width of head, 
lateral pronotal margins convergent anteriorly, dorsopleural carinae oblique 
and incomplete, posterior margin very slightly concave, disk elevated and 
without sculpturing; scutellum not striate behind transverse sulcus. Forewing 
with membrane including apical portions of all apical cells, with three closed 
anteapical cells of which bases of outer two are proximal to claval apex, the 
innermost distal to claval apex, without an anteapical plexus of veins, texture 
coriaceous before membrane and with indistinct fine transverse rugae. Hind- 
leg with femoral setal formula 2:1:1, length of first tarsomere greater than 
combined length of two more distal tarsomeres and with two parallel rows of 
small setae on plantar surface. 
Male genitalia: Pygofer well produced, subtruncate apically, with a narrow 
acute dorsoapical process extending mesad, with a few macrosetae near base 
of process. Plates elongate triangular, each with a short row of setae. Style 
very long and slender, slightly expanded at apex, without a lateral lobe. Con- 
nective Y-shaped with arms and stem approximately of equal length, stem not 
extending posteriorly as far as midlength of style. Aedeagus slightly decurved 
with a pair of processes arising basidorsally, extending parallel to shaft to its 
apex. Paraphyses absent. 
Xenogonalia is known only from the type-species which is orange anteriorly, 
with an apical coronal black spot, and black wings. X. longicornis (Osborn) is 
known from the eastern slope of the Andes in Peru and from the Purtis River 
valley in Brazil. I have studied the holotype of this species. 
Xenogonalia is placed near Cardioscarta Melichar and Poeciloscarta Stal in this 
work because of similarities in the male genitalia to some representatives of 
those genera (e.g. Poeciloscarta of the cardinalis complex, and Cardtoscarta 
quadrifasciata (L)).

Ficure 180 
Type-species: Tettigonia fossulata Signoret (1855b:237). 
Length of male 8.4 mm, of female 9.5 mm. 
Head moderately produced, median length of crown approximately six- 
tenths interocular width and slightly less than four-tenths transocular width, 
anterior margin broadly rounded in dorsal view, without a carina at transition 
from crown to face, ocelli located before a line between anterior eye angles, 
each slightly closer to adjacent anterior eye angle than to median line of 
crown, disk of crown flattened between ocelli, without sculpturing or setae, 
lateral clypeal sutures extending onto crown and attaining ocelli; antennal 
ledges slightly protuberant, in lateral view with anterior margins oblique and 
rectilinear; clypeus convex medially, muscle impressions distinct, transclypeal 
suture obscure medially, clypellus with profile a continuation of contour of 
lower portion of clypeus.
