We have already seen that the first egg-cases laid 
by N os 16, 17 and 2 5 were from 10 to 20 mm. long; 
the first of N° 125 was from 10-20 mm.; that of N° 88 
was lost. Thus in four out of five cases the first egg-case 
laid by a fertilized female was either small or medium 
and of the fifth we know nothing. Seven of the un¬ 
fertilized cases were not labelled and three were lost. 
In table VII, I give the distribution of the remaining 
twenty-five; owing to the inclusion of N° 119, there 
is one more large egg-case ( 25 - 3 o) than in table IV C c\

Comment on this table is hardily necessary, con¬ 
sidered in conjunction with preceding ones and with 
the observations just referred to, it shows clearly that 
while the female delays oviposition owing to the ab¬ 
sence of a partner, she accumulates material for the 
building of egg-cases. Thus, if any are made, the 
first is not only larger, but in many cases is more 
thickly covered than normally, so that the width is 
also increased. The conclusions we arrived at in dis¬ 
cussing the size of the egg-cases, and more especially 
of those made by fertilized females and not labelled, 
were based on observation of the material; this ana¬ 
lysis confirms them.
