CICADELLINAE: PART 2. NEW WORLD CICADELLINI 621 
in yuracensis, n. sp. The finely punctate surface of the crown is intermediate 
between the granulate coronal surface in stylata and the coarsely punctate con- 
dition in the other species of the genus. 
Oragua hualla, NEw species 
FicurE 503, PAGE 622 
Length of male 6.6-8.3 mm, of female 8.3 mm. Head with median length of 
crown varying from less than one-half to slightly less than six-tenths inter- 
ocular width and from slightly less than three-tenths to slightly more than 
one-third transocular width; ocelli located on a line between anterior eye 
angles, surface of crown not, or only obscurely sculptured, surface elevated 
near middle of posterior margin; antennal ledges with anterior margins 
slightly concave; transclypeal suture obsolete medially. Pronotum and 
scutellum without sculpturing; forewing without a membrane, base of fourth 
apical cell located more proximally than base of third, wing surface without 
sculpturing, middle anteapical cell with at least one supernumerary cross 
vein; first posterior tarsomere with length approximately equal to combined 
length of two more distal tarsomeres. Male pygofer thickly beset with setae on 
posterior two-thirds and basiventrally, the dorsoapical setae stouter than the 
others; plates extending posteriorly almost as far as pygofer apex, with 
numerous fine setae; style extending posteriorly much beyond apex of con- 
nective, with preapical lobe, apex narrow and subtruncate; aedeagus short 
and very broad in lateral view, with a pair of short dorsoapical processes; 
paraphyses asymmetrical, with a short stalk leading to a broad platelike por- 
tion which may bear a ramus laterally. Female abdominal sternum VII with 
posterior margin slightly oblique on each side of truncate median portion. 
Crown brown with a somewhat anchor-shaped ivory median marking that 
is edged in black before and behind its transverse portion and with additional 
ivory markings bordering inner eye margins and on posterior margin behind 
eyes; pronotum tan with three ivory to orange spots bordering anterior 
margin and a median ivory stripe on posterior three-fourths and extending to 
apex of scutellum; scutellum with a pair of black spots flanking the median 
line at base, remainder tan (the median line of the scutellum is orange in one 
specimen); forewings translucent tan, each with a dull ivory longitudinal line 
beginning in base of clavus laterad of lateral angle of scutellum, interrupted 
by claval suture and continued in brachial cell to its apex; face, thoracic 
pleura, and legs paler tan, the muscle impressions of the clypeus darker. 
Holotype and three additional males and three females, Hudnuco, Peru, 
January 27, 1947, 6500 ft. (AMNH). One male, Arequipa, Peru, August 21 
(Cockerell) (CAS). 
O. hualla, n. sp., may be distinguished from other species in the genus by 
the form of the aedeagal shaft, by the elevated posterior portion of the crown, 
and by the color pattern.
