SAMOUELLE'S 



motion and suction cause so many small swellings 

 or abscesses, beneath the skin, which growing 

 gradually larger, become externally visible, exhibit- 

 ing so many tubercles an inch or more in diameter, 

 with an opening at the top of each, through which 

 may be observed the larva, imbedded in a purulent 

 fluid : its appearance is that of an oval maggot, of a 

 yellowish white colour while young, but growing 

 gradually darker as it advances in age, till at the 

 time of its full growth it is entirely brown. It is 

 chiefly in the months of August and September that 

 the eggs are laid, and the larvae remain through the 

 ensuing winter and till the latter part of the next 

 June before they are ready to undergo their change 

 into chrysalis. At this period they force themselves 

 out from their respective cells, and falling to the 

 ground, each creeps beneath the first convenient 

 shelter, and lying in an inert state becomes con- 

 tracted in an oval form, but without casting the 

 larva skin, which dries and hardens round it. When 

 the included insect is ready for exclusion, it forces 

 open the top of pupa or chrysalis coat, and emerges 

 in its perfect form, having remained within the 

 chrysalis somewhat more than a month." Shaw.
