the ocelli, in the absence of an anteapical lobe on the style, in the presence of 
pygofer processes and the absence of paraphyses. The genus is named in 
honor of Dr. John T. Medler whose revisions of the genus Erythrogonia 
Melichar and Agrosoma Medler have been very helpful in the present study. 
Medlerola motiva, NEW SPECIES 
Figure 354 
Structural characters as in generic description. Color of dorsum, including 
forewings, castaneous, with a median dorsal ivory vitta extending through 
pronotum and most of crown but with its slightly bifid anterior extremity oc- 
curring behind apex of crown; forewings with a transcommissural lobate ivory 
band at level of scutellar apex but not extending laterally much beyond claval 
suture on each forewing, and a triangular transverse pale mark extending 
from costal margin into inner apical cell near its base; face, propleura, and 
legs stramineous. 
Holotype and two additional males and one specimen without abdomen, 
Maroni River, French Guiana (NCS). Holotype on indefinite loan to USNM.

Ficures 355-358 
Type-species: Cicadella corrugipennis Osborn. 
Length 4.1-5.9 mm. 
Head weakly produced, median length of crown from slightly less than 
four-tenths to slightly less than six-tenths interocular width and from approx- 
imately one-fourth to slightly more than one-third transocular width, anterior 
margin broadly rounded in dorsal view, without a carina at transition from 
crown to face, ocelli located on or slightly behind a line between anterior eye 
angles, each equidistant from adjacent anterior eye angle and median line or 
slightly closer to latter, crown with area between ocelli convex, without a me- 
dian fovea and without sculpturing or setae; lateral clypeal sutures extending 
onto crown and attaining ocelli; antennal ledges not protuberant, in lateral 
view with anterior margins rectilinear and vertical; clypeus flattened medially, 
muscle impressions not very distinct, face without pubescence, transclypeal 
suture complete or not medially, clypellus with contour either continuing 
profile of clypeus or curved more strongly and more nearly horizontal as a 
result. 
Thorax with pronotal width greater than transocular width of head, lateral 
margins convergent anteriorly, dorsopleural carinae complete, posterior 
margin concave, disk with a few transverse rugae on posterior portion. Fore- 
wing with membrane usually including all of apical cells except outer portion 
of outer apical cell (less extensive in R. fulgidus (Melichar)), some of veins 
indistinct, not elevated, with four apical cells of which base of the fourth is 
more proximal than base of third, without an anteapical plexus of veins, tex- 
ture coriaceous but with two longitudinal translucent bands; forewings of
