gross and unwieldy that it lies flat on its side when dug out 
of its retreat in the soil. 
In this state the grub lives three years. The series of 
changes the insect passes through in its whole existence is 
as follows : in the months of May or June the 
beetles pair, and the females lay from forty to 
fifty eggs in loose dirt below the surface. 
These eggs, according to Mr. Riley, hatch in 
the course of a month, and he adds that the 
grubs growing slowly, do not “attain full size 
till the early spring of the third year, when they 
construct an ovoid chamber lined with a gela¬ 
tinous fluid.” This fluid hardens, we may add, Pupa of May 
forming a glazed inner wall. The chrysalis, Beetle * 
or pupa (Fig. 19), may be found in these cells about six 
inches under the surface in May, and rarely in the autumn.
