Crown and pronotum fuscous with small irregular yellow spots; scutellum 
with basal portion fuscous, usually with a median pale stripe, apical portion 
pale; forewing fuscous, with small yellow spots to middle of anteapical cells 
except a larger round yellow spot at base of wing and a similar one near mid- 
dle of corium, both broadly black-bordered; face and thoracic pleura brown 
with small pale markings. 
Holotype and seven additional males, ‘“T'aperina”’, Brazil; one male, ‘‘San- 
tarem’’, Brazil (CM). One male, ‘‘Santarem”’, Brazil (C. F. Baker collection) 
and one male, near Alemquer, Para, Brazil (C. F. Baker collection) (USNM). 
I have been unable to locate ‘““Taperina”’. Presumably the “‘Santarem” is in 
Para. 
O. osborni, n. sp., is probably closer to O. galerula than to other species of the 
genus. It differs from all other species in the shape of the paraphyses. I take 
pleasure in naming this species in honor of Dr. Herbert Osborn who did 
much work on neotropical leafhoppers. This is the species he identified as 
nebulosa (Signoret), but it doesn’t agree very well with the original description 
nor with my notes on the lectotype. It is not the same species Melichar iden- 
tifed as nebulosa (Signoret) in MMB.

Length of male approximately 7.5 mm, of female 8.5 mm. Head with me- 
dian length of crown varying from slightly less than one-half to slightly 
greater than one-half interocular width, and from three-tenths to one-third 
transocular width; ocelli located on a line between anterior eye angles, sur- 
face of crown densely punctate; antennal ledges with anterior margins con- 
cave; transclypeal suture obsolete medially. Pronotum without sculpturing; 
scutellum with sculpturing weak or absent on its posterior portion; forewing 
with all of apical cells membranous, but base of membranous portion not 
sharply delimited, base of fourth apical cell located more proximally than 
base of third, wing surface not punctate before membrane. Male pygofer with 
macrosetae on apical two-thirds; plates extending posteriorly almost as far as 
pygofer apex, each with uniseriate macrosetae; style not extending posteriorly 
nearly as far as apex of connective, without preapical lobe, apex foot-shaped; 
aedeagus with very short dorsal apodemes, aedeagus in lateral view with shaft 
curved dorsally at midlength, its apical half almost at a right angle to its 
basal half, with a short angularity on each side at base of apical half; para- 
physes with stalk approximately equal in length to slender tapered sub- 
parallel rami. Female abdominal sternum VII with a posterolateral angle on 
each side and with a narrow acute median projection from posterior margin. 
Crown and pronotum brown, crown with a broad orange marking border- 
ing inner margin of each eye, middle of disk with a yellow marking in form of 
a “V” but with anterior end of each arm curved posterolaterally; pronotum 
with a large marginal tan spot on each side of anterior margin and a longi- 
tudinal orange marking extending posteriorly from it towards posterior pro- 
notal margin, with a number of small yellow spots on brown background of
