CICADELLINAE: PART 2. NEW WORLD CICADELLINI 141 
miles E. Rio Acobamba, Junin Prov., Peru, December 3, 1954 (E. I. Schlinger 
and E. S. Ross) (CAS). 
D. mann is named in honor of the collector of the holotype, the late Dr. 
William M. Mann, former director of the National Zoological Park, 
Washington, D. C. who collected many interesting Homoptera in tropical 
America. The species is closely related to D. selvanus, n. sp. (below) in the dis- 
cussion of which distinguishing characters are presented. 
Dilobopterus selvanus, NEW SPECIES 
FiGuRE 82, PAGE 124 
Length of male 7.6 mm. Head with median length of crown slightly less 
than one-half interocular width and slightly more than one-fourth transocular 
width, anterior margin much more strongly produced than in D. axillaris, n. 
sp., very broadly rounded in dorsal aspect; ocelli located behind a line be- 
tween anterior eye angles, each slightly closer to median line of crown than to 
adjacent anterior eye angle, with a transverse concavity across ocelli; antennal 
ledges with anterior margins obliquely convex. Forewing almost entirely mem- 
branous, veins indistinct in basal half. Other structural characters as in ax- 
ullaris. 
Pygofer well produced with macrosetae numerous and close-set, occurring 
over most of disk except basidorsal portion and a narrow diagonal area ex- 
tending from near base posterodorsally to apical portion of disk, with a well 
developed dorsal process curved strongly mesally, concavely truncate apically, 
not extending to median line; plates not extending nearly as far posteriorly as 
pygofer apex, each triangular, abruptly narrowed in basal half, broadened 
slightly before apex, with multiseriate small macrosetae; style extending 
posteriorly much beyond apex of connective, with a preapical lobe; con- 
nective Y-shaped, with arms widely divergent, keeled medially; aedeagus sym- 
metrical with a dorsal lobe extending posterodorsally almost parallel to shaft, 
separated from latter by a narrow, deep excision; paraphyses asymmetrical, 
consisting of a broad ramus extending dorsally then curved posteriorly, some- 
what hooked apically, and of a much narrower slender shorter tapering 
process arising at base of larger ramus and not extending as far as apex of lat- 
ter. 
Crown, pronotum, and scutellum sordid yellow, crown with anterior margin 
broadly black except a median anchor-shaped marking, arcs in areas of mus- 
cle impressions and a C-shaped marking tangential to each inner eye margin 
all of which are yellow, pronotum with margins black, the anterior margin in- 
cluding a number of angular, arcuate or lobate very small yellow spots and a 
larger quadrate median yellow spot near anterior margin, scutellum yellow 
with basal angles and transverse suture black, latter with a median angular 
posteriorly-directed extension; forewing hyaline, with costal margin narrowly 
black; hindwing with jugal lobe black, extending posteriorly beyond apex of 
clavus of forewing with wings in rest position. Face yellow with a broad black 
median stripe across clypeus and all of clypellus and most of lora and adja- 
cent genae. Thoracic pleura and legs except fuscous apical halves of hind 
tibiae, yellow.
