but not in Hower, and the beetles were plentiful. On 

 May 80th, 1903, two beetles were found at Reigate in my 

 garden, from larvje turned out last autumn, and one or 

 two a day have appeared since. Tiicse are all soft and 

 immature. 



The 07-inct taken at Pino April 27th, paired on May 7th 

 and May 8th, but not for long periods. They were placed 

 again in the same jar May 24th, and remained paired for 

 forty-eight hours on May 25th, 26th and 27th. The 

 female again paired with one of the Eeigate beetles May 

 30th and 31st. On June 4th she laid two eggs ready 

 to hatch, and two more on the 5th. Of these one failed 

 to hatch, the others hatched on 5th and 6th, and larvse are 

 now feedinof. 



These are probably the result of the pairing of May 7th 

 and 8th, but this is by no means certain. The beetles do 

 not seem happy or to feed freely, when kept solitarily.
