 than a cherry. 



All, however, have the same shape and the 

 same appearance, so much so that, with the 

 exception of the small cocoons of the Fu- 

 neral-pall Cetonia, I cannot distinguish one 

 from the other. Here the work tells me 

 nothing of the worker; I must wait until the 

 adults come out to name my discoveries cor- 

 rectly. However, as a general rule, subject 

 to many exceptions, the cocoons of the Gol- 

 den Cetonia have an outside facing of the 

 insect's droppings, set close together with- 

 out any definite arrangement. Those of the 

 Metallic Cetonia and the Dark-brown Ceto- 

 nia are covered with remnants of decayed 

 leaves. 



We must regard these differences as re- 

 sulting merely from the materials that sur- 

 round the grub at the moment when it is 

 building its cocoon and not from a special 

 method of construction. It seems to me 

 that the Golden Cetonia likes building in 

 the midst of its old dejecta, now hard gran- 

 ules, while the other two prefer cleaner 

 spots. Hence, no doubt, the diversity of 

 the outer layer. 



In the case of the three larger Cetoniae,
