Fennah — Fulgoroidea 
57 
by Melichar (1914 Ver. Nat. Ver. Brunn 53: 106). The 
latter species, based on Stal’s labelled specimen in the 
Berlin collection, requires a new name, for which Ladella 
stali is now proposed.

Male. Length, 5.6 mm. ; tegmen, 4.9 mm. 
Vertex 3.3 times as broad as long in middle line, medi- 
ally carinate, carina broad, obsolete at apex, simple at 
base; frons in middle line 1.5 times as long as broad, a 
broad callus across basal margin, median carina rather 
broad. Pronotum with disc large, carinae stout, two

mesonotum relatively long, lateral earinae of disc parallel 
in basal half. Tegmina with costal area broad with 
about 14 transverse veinlets, nodal line straight, Sc + R 
fork distad of M fork which is distad of Cu 1 fork, none 
of these veins forked again before nodal line, membrane 
with five or six irregular ranks of transverse veinlets, 
about 16 cells adjoining apical margin between node and 
apex of clavus. Post-tibiae with three spines. 
Anal segment relatively narrow, each lateral angle pro- 
duced into a spatulate vertical lobe. AMeagus laterally 
flattened, upeurved, distally, a long spine lying below it 
on left, bent across to right and curved upward at apex,
