SPOLIA ZEYLANICA. 
of the Mahaweli-ganga (river.) This species does not have the body 
margined with red as in the preceding. The crested Deltonotus 
tectiformis (plate I., fig. 2) differs in its habits materially from 
those above described in that it lives on the ground among fallen 
leaves in the jungle under shade trees. The body of this insect 
is shaped somewhat like a beech nut, being compresso-cristate 
and gently arched above from before backward. One of the 
unique species is the interesting horned Gladonotus latiramus 
figured on plate I. fig. 1, the only specimen of which was 
discovered on a bungalow wall. Its body is provided with many 
spiniform tubercles, and the pronotum is elevated forward into a 
vertical ramus. The very rough-backed Lamellitettix acutus 
(plate II., fig. 6), with its lateral lobes of the pronotum outwardly 
projecting in the form of broad-based spines, is represented by 
one female specimen taken from the stem of a tree in a thick 
jungle. Contrasting with the foregoing is the graceful bodied 
Griotettix tricarinatus (plate III., fig. 15) with delicate spines 
arming the lateral lobes. It seems to be one of the commonest 
species locally, appearing in considerable numbers on the margin 
of a river, the side of a railroad bank and on grass lands. A 
nearly allied species, Griotettix spinilobus (plate III., fig. 12), 
was found on swampy ground. The rather large Acanthalobus 
miliarius (plate II., fig. 8) was found frequenting rice fields, the 
dry bed of a tank, and the banks of a stream. The long-wing 
somewhat slender-bodied Loxilobus acutus (plate I.. fig. 3) was 
caught at light. Another smaller species Loxilobus rugosus (plate 
III., fig. 16) inhabits swampy ground and grass lands. Of bizarre 
forms Systolederus greeni (plate II., fig. 9) is an excellent example. 
The large globose eyes drawn very close together present a most 
peculiar aspect, being compressed and elevated considerably 
above the somewhat flattened dorsum. It lives on hot dry rocks 
away from water arid is very active on the wing. The small¬ 
bodied Mazarredia insularis (plate II., fig. 7) is often coloured 
like the natural lichens and mosses among which it lives and is 
very inconspicuous. The small apterous species Apterotetiix 
obtusus (plate III., fig. 13) has a very short pronotum and angu- 
late head. It lives among fallen leaves under shade trees, having 
similar habits in this respect to Deltonotus tectiformis previously 
referred to. It is also found in grassy fields. The long-wing 
Tettix atypicalis (plate III., fig. 14) lives on grassy land. The 
short-wing form, Tettix a. ceylonus , lives in similar situations. 
Euparatettix personatus (plate II., fig. 10) abounds in the rice 
fields. The beautiful Hedotettix attenuatus (plate III., fig. 18) 
is remarkably variable in colour, often having a light longitudinal
