aedeagus and the paraphyses are similar to those of J. diversa (Signoret) and 
might be considered as variants of the several forms of these found in the lat- 
ter species, but it would be necessary also to assume that the female sternum 
VII and the color pattern are also variants of the conditions found in diversa, 
assumptions that appear unwarranted for lack of intermediate conditions. 
Iragua perplexa, NEW SPECIES 
FiGuRE 331, PAGE 409 
Length of male 8.4 mm. Head with median length of crown varying from 
seven-tenths to three-fourths interocular width and slightly less than one-half 
transocular width, antennal ledges in lateral view with anterior margins con- 
vex. Pronotum without sculpturing; forewing with texture coriaceous. Male 
pygofer with a short apical process, style extending well beyond apex of con- 
nective, apex subtruncate and acutangular laterally; aedeagus curved 
gradually dorsally with anteapical dorsal processes and paired apical 
processes; paraphyses with stalk longer than rami which are tapered and 
divergent apically. Female unknown. 
Crown sordid brown suffused anteriorly with orange; pronotum, scutellum, 
and forewings yellow, with an anterior pronotal marginal band, an arcuate 
band across posterior portion of pronotum and anterior portion of scutellum 
and extending posteriorly a short distance along costal margin of forewings, 
brown; a pentagonal median marking astride commissural margins and in- 
cluding scutellar apex and subtended by an arcuate transcommissural band 
that attains costal margin of each wing, dark red; an arcuate dark red trans- 
verse band on each wing extending from costal margin across anteapical cells 
to inner anteapical cell; upper portion of face orange, remainder of face 
yellow, concolorous with thoracic pleura and legs. 
Holotype male, Marcapata, Peru (HNHM), and one additional male, same 
data (MMB). 
I. perplexa is probably more closely related to circulifera (Taschenberg) than 
to other species in the genus, but the larger size and distinctive color pattern 
of perplexa will separate the species readily without dissection, and the dif- 
ferences in the aedeagus are marked.

Microgoniella Melichar, 1926a:342. Type-species: Cicada pudica Fabricius, by subsequent 
designation of China, 1938d:183. 
Length 4.7-6.7 mm. 
Head moderately produced, with median length of crown varying from six- 
tenths of, to slightly more than interocular width and from slightly more than 
one-third to six-tenths transocular width, anterior margin usually broadly 
rounded in dorsal view, without a carina at transition from crown to face,
