was taken in March. Mr. Green remarks that the living insects 
are often coloured like and harmonize with the natural lichens and 
mosses, being very inconspicuous. Bolivar described the species 
from a male example which measured as follows :— 
Length of body 7 mm.; pronot. 10 mm.; post. fern. 5 mm. 
(Ceylon). 
Apterotettix , gen. nov. 
Plate III., figs. 13-13&. 
Body rugulose granulate. Face moderately oblique; facial 
frontal costa distinctly advanced before the eyes, not at all sinuate, 
united with the crown angulate in profile. Vertex subequal in 
width to one of the eyes, very slightly convergent forward, 
the front margin advanced beyond the eyes, provided with abbre¬ 
viated arcuate carinula on each side, little elevated laterally 
middle carinate, produced : viewed in front or in profile the 
vertex not lower than the eyes. Eyes of moderate size not 
appreciably prominent or elevated. Antennae inserted a little in 
advance of the lower fourth of eyes, slender filiform. Pronotum 
truncate in front posteriorly abbreviated not extended backward 
so far as the extremity of the abdomen ; dorsum between the 
shoulders subtectiform ; humeral angles obtuse ; scapular area 
moderately wide attenuate posteriorly; posterior angle of lateral 
lobes outwardly little produced, behind obliquely truncate. Elytra 
and wings absent or vestigial. Femora lightly compressed, first

Plate III., figs. 13-13&. 
Body small, rugulose granulate. Head not at all exserted ; face 
moderately retreating. Vertex subequal in width to one of the 
eyes, the front border convex, advanced slightly beyond the eyes, 
frontal carina on each side laterally arcuate abbreviated, barely 
elevated, mid-carina viewed in profile, in female, little elevated in 
front and produced; viewed in front the vertex hardly lower 
than eyes subtransverse. Facial frontal costa viewed in profile 
distinctly advanced before the eyes substraight, united with the 
vertex angulate, viewed in front moderately sulcate. Eyes of 
moderate size globose, not appreciably prominent. Antennas 
moderately long, very slender filiform articles elongate, inserted 
between the lower fourth of the eyes. Posterior ocelli in profile 
visible just before the middle of the eyes. Pronotum subflattened 
above, transversely between the shoulders subtectiform, in front
