143 
arcuate, posteriorly subconcave; elvtral sinus shallow; the in¬ 
ferior sinus deeply angularly excavate ; the posterior angle of 
lateral lobes with the apex moderately wide rounded-truncate. 
Elytra oval apex rounded ; wings caudate, extended strongly 
beyond the apical process. Femora slightly compressed ; anterior 
and middle femoral margins entire or indistinctly undulate, finely 
crenulate or serrulate ; posterior femoral margins serrulate; 
posterior tibiae undulato-curvate, lateral margins subserrulate 
spinose; first and third articles of posterior tarsi subequal in 
length, the third pulvillus as long as the first and second together, 
the apices spiculate. Margins of legs, the mouth parts and under 
parts of body hirsute. Ovipositor short, the superior blade being 
unusually wide as compared to the length. Colour grayish or 
ferrugineous with fuscous macula on each side of the dorsum 
behind the shoulders, legs annulated with fuscous.

Three females. One bearing the locality (Kandy) measures the 
longest in the series and was taken “from grass land in November, 
1903.” The second example from Peradeniya was “caught at light” 
in July, 1903, being also a long-wing form. The third specimen 
from Dikoya was taken in February, 1903, “ from grass land.” The 
last mentioned specimen is a variety having the pronotum 
anteriorly more strongly compresso-elevated between and before 
the shoulders, the median carina of pronotum more elevated 
cristate. These peculiarities are correlated with shortened wings 
and abbreviated pronotal process ; the latter not being extended 
quite so far backwards beyond the posterior femoral knees. This 
species being dimorphic passes into the next form, some examples 
of which are very much reduced in size. 
19 .—Tettix atypicalis ceylonus , form. nov. 
Related to the preceding T . atypicalis , but having the vertex 
slightly more advanced as viewed from above ; the pronotum and 
wings more or less abbreviated; the antero-dorsal margin of 
pronotum obtuse angulate ; the body often very diminutive in 
stature; the middle femora in the male distinctly expanded.
