CICADELLINAE: PART 2, NEW WORLD CICADELLINI 1011 
Coronigoniella rohweri, NEW SPECIES 
FIGURE 829, PAGE 1021 
Length of male 5.9-6.0 mm, of female 6.0-6.5 mm. Head with median 
length of crown varying from slightly less than six-tenths to two-thirds inter- 
ocular width and four-tenths or slightly less than four-tenths transocular 
width, ocelli each approximately equidistant from adjacent anterior eye angle 
and median line of crown, crown with transverse concavity absent, clypellus 
with contour of its lower portion continuing profile of remainder of face. 
Hindleg with length of first tarsomere much greater than combined length of 
two more distal tarsomeres. Male pygofer broadly rounded apically, with 
process very short, anteapical, very close to posteroventral pygofer margin 
(easily overlooked); plates extending posteriorly as far as pygofer apex, each 
with uniseriate macrosetae; style extending posteriorly beyond apex of con- 
nective, rounded apically; aedeagus without a preatrium, shaft with ventral 
margin rectilinear in lateral view, shaft parallel-margined. 
Color very much as in C. bonita, n. sp. 
Holotype and two additional males and four females, Zaruma, Ecuador, 
November 26, 1915 (F. W. Rohwer) (USNM). 
C. rohweri, n. sp., is named in honor of the collector of the type-series. The 
straight aedeagal shaft, without processes, and the very small pygofer 
processes are distinctive characters. 
Coronigoniella tiarae, NEW SPECIES 
FicurE 825, pace 1014 
Length of male 5.5-6.0 mm, of female 6.3-6.5 mm. Head with median 
length of crown varying from slightly less than six-tenths to almost seven- 
tenths interocular width and from slightly more than one-third to slightly less 
than one-half transocular width, ocelli each approximately equidistant from 
median line of crown and adjacent anterior eye angle, crown with or without 
a transverse concavity (weak when present), clypellus with contour of its 
lower portion continuing profile of remainder of face. Hindleg with length of 
first tarsomere much greater than combined length of two more distal tar- 
someres. Male pygofer tapered to narrowly rounded apex, in lateral view with 
a process arising from inner wall near apex and another arising distinctly 
more basiventrally on posteroventral pygofer margin, both processes slender 
and acute; plates extending posteriorly beyond pygofer apex, each with uni- 
seriate macrosetae; style extending posteriorly beyond apex of connective, nar- 
rowly rounded apically; aedeagus without a preatrium, shaft in lateral view 
with ventral margin concave in basal half, convex in apical half and with a 
pair of anteapical ventral flanges, shaft with minute verrucae (visible at mag- 
nification of more than 150 diameters), without processes. 
Color as in C. bonita, n. sp. 
Holotype and two additional males and four females, Botanical Gardens, 
Port-of-Spain, Trinidad, October 13, 1918 (Harold Morrison); one male and 
three females, Archbold Estate, Roxborough, Tobago, November 6, 1918 (H.
