LI.—Some undescribed Ethiopian Cicadidee, 
By W. L. Disrant. 
THE following descriptions refer to genera and_ species 
recently received from various sections of the Ethiopian 
region, and the types of which are contained in the British 
Museum :— 
MAROBODUUS, gen. nov. 
?. Head with the front subconically produced and cen- 
trally longitudinally depressed, about as long as_ space 
between eyes, which are large and prominent; pronotum 
narrowed anteriorly, the lateral margins concavely excavate ; 
mesonotum (including cruciform elevation) a little shorter 
than head and pronotum together ; abdomen in ? longer 
than the space between the apex of head and base of cruci- 
form elevation ; tegmina and wings hyaline; tegmina with 
eight apical areas, of which the uppermost is smallest, the 
fourth broadly convex at base, thus narrowing the apical half 
of the second upper ulnar area; radial. area with the lower 
vein strongly angulated and produced beneath, the ulnar area 
immediately beneath it being very wide and apically upwardly 
recurved ; wings with six apical areas, the uppermost of which 
is subglobose. 
The peculiar venation of the tegmina, especially of the 
radial area, and the upwardly turned apex of the ulnar area
