CICADELLINAE: PART 2. NEW WORLD CICADELLINI 763 
bearing dorsal teeth on portion beyond basal curvature, the teeth fairly uni- 
form and usually bearing secondary denticles (weak and without secondaries 
in dorsifascia), apices rounded or acute (dorsifascia). Pygofer narrowly rounded 
posterodorsally, disk with macrosetae on apical one-half to two-thirds. 
Species of Fonsecaiulus either have conspicuous paired longitudinal black vit- 
tae on the crown and pronotum or a median yellow band from the apex of 
crown to the apex of clavus. 
Fonsecaitulus occurs in Venezuela, eastern and southern Brazil, and Bolivia. 
F. gaudtalis, n. sp. was collected on Vernonia sp. The genus is named in honor 
of Dr. José Pinto da Fonseca who has made notable contributions to our 
knowledge of neotropical Homoptera. 
Fonsecaiulus, new genus, is related to Erythrogonia Melichar from which it 
may be distinguished most readily by the lack of plaquelike markings. Most of 
the species have longitudinal vittae similar to those of Sibovia China, but the 
posterior extent of connective of the male is shorter in relation to the styles, 
and the teeth of the second valvulae of the ovipositor are more extensive than 
in Stbovia. 
My identification of Entogonia cognata Schmidt is based on the female lec- 
totype. I have seen five additional specimens from Santa Catharina, Brazil, 
only one of which is a male, and somewhat teneral. The relationship of the 
paraphyses to the base of the aedeagus (fig. 625g) is not clear in this 
specimen. 
I have identified Cicadella dorsifascia Osborn on the basis of the female 
holotype and males compared with it. 
The present interpretation of Tettigonia flavovittata Stal is based on a study of 
the female lectotype, and a male compared with it. I think the present identi- 
fication of Tettigonia sanguineovittata Signoret agrees with the lectotype, a fe- 
male. Signoret’s original illustration of that species isn’t very accurate, as he 
pointed out. The anterior dorsum is similar to my sketch of the lectotype of 
cognata Schmidt.
