Dr. T. A. Chapman's 



of survival amongst the beetles taken. Comparing these 

 with the numbers that died, and eliminating those that 

 escaped, that were given away, or were otherwise disposed 

 of, these two represent the survivors rather of from eight 

 to ten beetles living in August 1902. 



About this date (March 4th, 1908) I examined the pot 

 io which a number of larvoe had gone down in September 

 and October, and was vexed to find that the earth was 

 apparently quite dry, and two larvee that I unearthed from 

 near the surface were apparently quite dead and dried up, 

 with the ventral and dorsal surfaces almost in contact. 

 Placing these in warm water, after twenty-four hours both 

 were alive and active. Though still looking somewhat 

 starved and contracted, they obviously had a good deal 

 of tissue within their skins. 



I was, therefore, encouraged to damp the pot of earth 

 and put it in a warm place. Unfortunately again, I 

 overdid this. 



On March 23rd I found a perfect beetle had emerged, 

 and forthwith examined the pot and contents. I found 

 it contained several beetles ready to emerge, one living and 

 one dead pnpa, a number of dead larva3, distended almost 

 to bursting by excess of imbibition but really close on 

 pupation, and others that had died at an earlier stage. 



Disappointing as this result was, disappointing also 

 because so much due to my own want of intelligent care, 

 still, it enables me to say that I have reared the beetle 

 from the egg, and also to describe and figure the papa. 



The hibernating chamber of the larva, in which it 

 pupates in the spring, remaining probably as a pupa 

 from two to four weeks, according to temperature, is 

 nearly spherical, and about f inch in diameter, with the 

 interior wall pressed smooth. 



The following data, giving dates of hatching of batches 

 of eggs laid at the same time, give some indication of the 

 various degrees of maturity of the eggs at the date of 

 laying.
