CICADELLINAE: PART 2. NEW WORLD CICADELLINI 419 
each approximately equidistant from median line of crown and adjacent an- 
terior eye angle, crown with a transverse concavity across ocelli; clypeus with 
muscle impressions not distinct except in dorsal portion. Forewing with base 
of middle anteapical cell occurring more proximally than base of inner ante- 
apical cell and more proximal than apex of clavus, base of outer anteapical 
cell at approximately same level as base of middle anteapical cell. Male 
pygofer narrowly convex at apex, with a number of elongate macrosetae in a 
diagonal group parallel to posteroventral pygofer margin, dorsal pygofer 
margin with a short, very broad convex lobe near midlength; plates some- 
what abruptly narrowed at midlength; aedeagus with a pair of short lateral 
processes arising in basal half, shaft slender, elongate, acute apically, without 
processes arising more distally than preceding, paraphyses absent. Female un- 
known. 
Color of crown, pronotum, scutellum, and forewings black except a faint 
translucent costal area opposite outer anteapical cell and a pale rounded spot 
on clavus and extending to base of outer apical cell; face black with a few 
pale arcs at base of clypeus, margin of face and color of pleura and venter as 
in M. gracilis, n. sp., above. 
Holotype male, Potrerillos, Panama, January 2, 1935 (J. W. MacSwain), on 
indefinite loan to USNM from NCS. 
M. plutontella, n. sp., is close to M. gracilis, n. sp. (above), from which it dif- 
fers in the lobe of the dorsal male pygofer margin being more convex and less 
prominent, and in the unstalked condition of the aedeagal processes.
