At the end of July, the nymph appears, 

 first amber-yellow all over, next currant-red 

 on the head, horn, corselet, breast and legs, 

 while the wing-cases have the pale hue of 

 gum arable. A month later, by the end of 

 August, the perfect insect releases itself from 

 its mummy wrappers. Its costume, now

 Sacred Beetle. Head, corselet, breast and 

 legs are chestnut-red. The horn, the epis- 

 toma and the denticulations of the fore-legs 

 are shaded with brown. The wing-cases are 

 a rather yellowish white. The abdomen is 

 white, excepting only the anal segment, which 

 is an even brighter red than the thorax. I 

 perceive this early colouring of the anal 

 segment, while the rest of the abdomen is 

 still quite pale, in the Sacred Beetles, the 

 Gymnopleuri, the Onthophagi, the Geo- 

 trupes, the Cetoniae ^ and many others.
