experienced naturalist has long since got utterly tired of. 

 But has your rash objector ever lighted upon that rare larva 

 which lives among the periwinkles, and exactly imitates a 

 periwinkle petal ? Has he ever discovered those deceptive 

 creatures which pretend for all the world to be leaves of 

 lady's-bedstraw, or dress themselves up as flowers of 

 buttonweed ? Has he ever hit upon those immoral cater-

 so as to resemble flower buds, and thus deceive the insects 

 upon which they prey.' There is something hideously 

 wicked and cruel in this lowest depth of imitative infamy, 

 A flower-bud is something so innocent and childlike ; and 

 to disguise oneself as such for purposes of murder and
