CICADELLINAE: PART 2. NEW WORLD CICADELLINI 117 
Holotype male, Itaituba, Brazil (USNM). A number of additional males. 
~Monsén Valley, Tingo Maria, Peru, October 29, 1954 (CAS). One male, 
Tingo Maria, Peru, October, 1946 (AMNH). Four males, ‘“‘Peru’’; Callanga, 
Peru; and San Antonio, Bolivia (RMS). One male, Covendo, Bolivia 
(USNM). Two males, Cuenca, Ecuador (BM). Two males, Yungas de 
Palmar, Bolivia, Nov. 19, 1960 (SSM). Three males, ‘“‘Peru’’ and Loja, 
Ecuador (MHNP). Three males, Bafios, Ecuador; Marcapata, Peru; and 
Mapiri, Bolivia (NCS). 
D. fenestratus, n. sp., differs from all other species with ventral pygofer 
processes in its color markings. Externally it is very similar to the species 
Fowler illustrated as Tettigonia mosaica Fowler (1899c: p1. 15, fig. 12) and of 
which he stated that the type was in the Vienna Museum, in the Signoret col- 
lection. The type locality of the Fowler species is ‘‘Mexico’”’. No specimens 
were found in the Signoret collection in Vienna. Metcalf identified (un- 
published) specimens from Marcapata, Peru and Mapiri, Bolivia with mosaica 
(Fowler). If the specimens Fowler saw from the Vienna Museum were mis- 
labeled, the present writer would agree with this. 
Dilobopterus knighti, NEW sPECIES 
FIGURE 98, PAGE 138 
Length of male 10.8 mm, of female 12.0 mm. Head with median length 
varying from four-tenths to slightly more than one-half interocular width and 
approximately one-fourth transocular width, anterior margin broadly round- 
ed in dorsal aspect, ocelli located behind a line between anterior eye angles 
and each approximately equidistant from median line of crown and adjacent 
anterior eye angle, with a slight transverse concavity before ocelli; other head 
characters as in D. fenestratus, n. sp. Pronotum not transversely rugose; fore- 
wing with veins indistinct, except apically; hindwing with jugal lobe not en- 
larged. 
Pygofer with macrosetae closely spaced, occurring over all of surface except 
basal portion, without processes; plates not extending as far posteriorly as 
pygofer apex, each triangular, with lateral margins regularly convex in basal 
third, mesal margins fused basally, with a single row of macrosetae on apical 
four-fifths; style extending posteriorly much farther than apex of connective, 
with a preapical lobe; connective subtriangular with a Y-shaped keel; 
aedeagus symmetrical, without processes; paraphyses paired, asymmetrical. 
Female abdominal sternum VII much as in the present illustration of D. 
croceus (Metcalf) (fig. 1112). 
Crown, pronotum, and scutellum each black-margined before and behind, 
the crown with posterior black margin narrow; each with a broad transverse 
pale yellow to orange band; forewings smoky, with scutellar transverse band 
continued across their bases almost to each costal margin, on each wing con- 
nected with a narrow longitudinal claval strip. within claval suture almost to 
claval apex and also with a broader, longer corial stripe extending to bases of 
third and fourth apical cells. Face pale with clypellus and apical half of clypeus, 
black.
