 sort of protection. Next comes the Twelve- 

 spotted Crioceris, who is established in the as- 

 paragus-berry from her early infancy. The 

 most favoured is the Lily-beetle, who, while 

 a grub, makes an ulster of her excretions. 



For the second time, we are here con-

 not different and the sizes dissimilar, we 

 should not know how to tell one from an- 

 other. And this pronounced resemblance in 

 figure is accompanied by a no less pro- 

 nounced lack of resemblance in instinct. 



The evacuator that soils its back cannot 

 have inspired the hermit living in cleanly re- 

 tirement inside its globe; the occupant of 

 the asparagus-berry did not advise the third 

 to live in the open and wander like an acro-
