on the 7th and 8th of September, and were forgotten 

 until they were dead, excepting four or five, and these 

 were put in a bottle with a small root of dock. 



The egg of sylvinus is globular, having a small 

 depression on some part of it, and is jet black in colour, 

 having a slightly shining surface. 



The newly hatched larva is of a whitish flesh colour, 

 tinged with brownish on the thoracic segments, with 

 brown head and plate. When four days old the head 

 and plate behind it and the anal plate show light

 shows through the body. Minute brown dots and 

 hairs are seen on the skin by the aid of a lens.
