present. This sub-genus has been left in disorder by Gory and Dejean, because it is very 

 difficult to be sub-divided. I offer the following rough approximation to the truth : —

82. Of the trichioid section of Cetonia, I believe no species comes from Asia or New 

 Holland. It represents the genus TricTiinus, and therefore all the typical species of it have 

 the elytra, or at least the lower surface of the body, covered with hair. Fabricius placed one 

 species of this groupe in his genus TricJiinus. The TRiCHioiDEiE, for the present, may be 

 sub-divided as follows : — 



A.— Body rather depressed. 



B. — Body rather convex.
