Hedotettix gracilis , De Hann. Brunner (1893, p. 111). 
Bolivar (1887, p. 284) gives the following measurements of 
H. gracilis: Length of body ?, 9 mm.; pronot. 10-11*5 mm,; 
post. fern. 6 mm. For festivus , length of body 6, 8 mm.; pronot. 
9*5 mm.; post. fern. 6*5 mm. His figure 24-24& of festivus agrees 
with the specimens which form the basis of my descriptions. 
24.— Hedotettix gracilis abortus , form. nov. 
A short-wing form of Hedotettix which appears to be a variety 
of gracilis is represented by three specimens. This form differs 
from gracilis in having the frontal costa more widely sulcate ; in 
the median carina of pronotum sloping backward instead of being 
arcuate; the pronotal process posteriorly abbreviate acute, extend¬ 
ing backward only to the posterior femoral apex or little beyond ; 
the wings extending very little beyond the pronotal apex; and 
differing as shown in the following measurements :—

The above two females, Kesbewa (Colombo), April, 1903, “ from 
dry rice fields.” One male from Pundalu-oya, March 3, 1903, 
“swept from grass fields.” I have a female example similar to 
this variety from Java, Pengalengan, 4,000ft. elevation. Bolivar 
mentions that the species is found in Southern India, Ceylon, 
and Java. It is also mentioned by Brunner (1893) as occurring 
in Teinzo, Rangoon, in lower British India. 
25.— Hedotettix attenuatus , sp. nov. 
Plate III., figs. 18-18A 
Nearly related to gracilis , but having the body very slender, the 
vertex narrower than one of the eyes, the front margin subtrun¬ 
cate ; the crown of head in profile not at all or barely elevated 
above the eyes ; the frontal costa moderately or narrowly sulcate, 
the rami not appreciably widened between the eyes ; the median 
carina of pronotum anteriorly not at all or slightly compressed 
between the sulci, the antero-dorsal margin strictly truncate, the 
dorsum between the shoulders narrow. The male very slender, 
having the eyes subexserted.
