376 On some undescribed Ethiopian Cicadidee. 
Lateral margins of pronotum a little convexly sinuate, 
posterior angles more or less strongly ampliate; head with 
front roundly triangularly produced, about as long as breadth 
between eyes; abdomen beneath with the lateral margins 
strongly inwardly roundly recurved. 
By the venation of the wings and the recurved margins of 
the abdomen beneath, this genus is also allied to Nablistes, 
Karsch, but from which the venation of the tegmina is 
altogether dissimilar.

@. Head virescent, blackly pilose, inner margins of eyes 
and two central longitudinal lines black, ocelli ochraceous ; 
pronotum ochraceous, a large central anterior and a central 
subbasal spot and the posterior marginal area virescent, the 
lateral areas with black suffusions ; mesonotum greenish 
ochraceous, with four longitudinal black fascie, of which 
the two central are sinuate and the outer ones shorter and 
posteriorly acute ; abdomen above ochraceous, the posterior 
segmental margins paler in hue; head beneath, sternum, 
and legs virescent, irregularly marked with black ; abdomen 
beneath ochraceous, the base and two small central spots on 
posterior segmental margins black, the roundly incurved 
lateral margins virescent, with heir segmental margins 
dark ochraceous, apical segment centrally black; tegmina 
dark ochraceous, the costal ‘membrane virescent, the venation 
fuscous, the longitudinal veins defining the ulnar areas broken, 
the radial area and basal cell paler in hue; wings pale 
ochraceons ; structural characters as in generic diagnosis.

STELLENBOSCHIA, gen. nov. 
Differs from Pauropsalta by the dilated tegmina. 
Type, S. rotundata, Dist. 
Melampsalta rotundata, Dist. Ann, & Mag. Nat. Hist. (6) ix. p. 324 
(1892). 
Differs from Pauropsalta by the shorter and broader 
tegmina, which at their greatest breadth are half as broad as 
their greatest length ; they are also strongly roundly arcuated 
from near base. As in Pauropsalta, the wing possesses only 
five apical areas, and in the tegmina the radial area is at its 
greatest breadth about half as broad as long.
