Observations made in the field would indicate that 
this probably does not exceed the average length of time 
required there, the time recorded above for the case observ- 
ed in black cotton soil being rather below the average. 
The eggs are laid somewhat irregularly, there being 
little of that comparatively orderly arrangement noted in 
the masses of the Rice Grasshopper. The masses them- 
selves are rather easily broken and the eggs are not at all 
firmly cemented together. However, the hole in the 
black cotton soil is a very solid one and under normal 
conditions there is little ee of the egg-masses coming 
to any harm. Plate II, Fig. 1 shows part of an egg-mass 
exposed in black cotton soil; above can be seen remains of 
the frothy or spongy mass which is deposited in the hole 
above the eggs. At times this spongy mass attains a 
length up to an inch, in some cases being longer than 
the egg-mass itself. Plate Vii ie..3 shows such a frothy 
plug in position above an egg-mass. Plate VII, Fig. 2 
shows an intact egg-mass, from which the frothy covering 
has been removed on one side to reveal the eges in their 
natural position. 
The egg-masses vary considerably in size and in the 
number of eggs contained in them. They are much 
narrower than those of the Rice Grasshopper while at 
the same time they tend to be somewhat longer. Measure- 
ments of twenty-one masses gave dimensions varying from 
23 mm. X 5°5 mm. to 13mm. X 6mm. Others have 
been found as short as 9 mm. and counts of eggs made on 
21 masses gave the following results:—72, 61, 56, 00, Ol, 
49, 47, 43, 49 41, 36, 36, 35, 35,32, 30, 2, 2 23, 21, 9, 8. 
The average is 38 ego's per mass. Records indicate that a 
female Jola Grasshopper lays on an average two ege- 
masses so that we have about 75 eges as the ‘approximate 
number laid per female. Consistent with the position 
occupied by the female in egg-laying, the ege-masses are
