female, more rugose ; the median carina of pronotum viewed in 
profile distinctly sinuate ; the posterior angle of the lateral lobes 
of pronotum narrowly obliquely excised, not at all acute spini-

One female and two males “ swept from grass land,” Pundalu- 
oya, in March ; two females and a male 44 swept from grass fields,” 
Pundalu-oya, in May, 1903. Three nymphs from 44 swampy 
ground,” March. E. Ernest Green. 
This species resembles Griotettix pullus , Bolivar. I have 
compared it with a mal q pullus kindly contributed to my collection 
by Professor Bolivar. It differs from that species in the frontal 
facial costa being more roundly protuberant before the eyes, and 
in the dorsal surface of the pronotum being more coarsely rugose. 
Griotettixpullus, Bol. (1887, p. 230), undoubtedly falls into the 
newly created genus Loxilobus , as do several other related species 
from other parts of the world.

Head exserted, elevated forward. Vertex less than half the 
breadth of one of the eyes, toward the front narrowed and 
subacuminate. Eyes approximate strongly globose. Face oblique, 
the contour sinuate ; frontal costa scarcely furcillate behind the 
ocelli, very lightly sulcate, viewed in profile compresso-elevated 
between the antennae. Antennae inserted below or barely between 
the lower part of the eyes scarcely in advance of them, fili¬ 
form, articles elongate, palpi filiform. Pronotum flattened above, 
in front truncate, posteriorly acuminate ; median carina incon¬ 
spicuous disappearing just behind the anterior border ; humeral 
angles obtuse ; posterior angles of lateral lobes extended outwards 
very frequently acute spinose or downward deflexed. Elytra oval; 
wings perfectly explicate. 
Legs elongate filiform ; anterior femoral carinse minutely gra¬ 
nulate ; genicular as well as the femoral lobes of the posterior
