Fic. 3—Egg-mass of Jola Grasshopper in lump of black cotton 
soil removed from infested field near Malebennur. Above the 
eggs, as well as surrounding them, is to be seen the brown spongy 
cement material poured out as a froth by the female during egg- 
laying. 
Fig. 4.—Nymph of Jola Grasshopper in the act of hatching. The egg- 
shell still surrounds the posterior end of the body and the insect 
is still inclosed in the amnion. 
Fic. 5.— Empty egg-shells with amnia in them. In the centre one, 
can be seen the two holes in the amnion from which the front 
pair of legs have been withdrawn. 
Fic. 6.—Blister beetle larva with head buried in an egg-mass of the 
Jola Grasshopper. The larva is feeding on the eggs. 
Fic. 7.—Larva of blister beetle removed from egg-mass. 
Fic. 8.—Syrphus fly found preying on nymphs of the Jola Grass- 
hopper. 
Fig. 9.—Mass consisting almost entirely of fragments of the skeleton 
of the Jola Grasshopper cast out by the common pariah kite 
(Milvus govinda, Sykes). 
PAPE WELL. 
Fic. 1.—Thorax of nymph of C. sphenarioides in first instar; (a) pro- 
thorax, (b) mesothorax, (c) metathorax here and in following 
figures. 
Fia. 2.-~ -Thorax of nymph in second instar. 
Fic. 3.—Thorax of nymph in third instar. The first signs of develop- 
ment of the wing-bud are to be seen on the mesothorax. 
Fic. 4.—Thorax of nymph in fourth instar. Development of wing-buds 
is now apparent on both meso- and metathorax. 
Fic. 5.—Thorax of nymph in fifth instar. The wing-buds have both 
become turned up. 
Fic. 6.—Thorax of nymph in the sixth instar. Anterior wing-bud (that 
of elytron or wing-cover) has grown backward almost to posterior 
edge of metathorax. 
Fic. 7.—Thorax of adult male of C. sphenarioides showing the elytron 
in its permanent condition. 
Fig. 8.—Antenna of nymph of first instar. 
Fic. 9.—Antenna of nymph of second instar. 
Fic. 10.—Antenna of nymph of fourth instar. 
Fig. 11.—Antenna of nymph of sixth instar.
