32 CETOXIIX-E. 



The Cetoniin.e consist of three well-defined Divisions, them- 

 selves sometimes regarded as forming Subfamilies. They are all 

 represented within our region and may be tabulated as follows : — 



Mesostenial epimera dilated above and usually 

 reaching the dorsal surface : base of the 



pronotum not meeting ridges upon scutellum [p. 32. 



and elytra (except in Dicranocephalus) .... l)iv. I. Cetoniini, 



Mesosternal epimera not dilated nor reaching the 

 dorsal surface : base of the pronotum meet- 

 ing ridges upon scutellum and elytra. [p. 222. 



Ilind coxfe widely separated Div. II. Valgini, 



Hind coxpe contiguous Div. III. Trichiini, 



[p. 249. 



The first Division consists of two Sections distinguished as 

 follows : — 



Mandibles thin and not sharp-pointed nor adapted 

 for biting, furnished with a free membranous 

 inner lobe Cetoniina, p. 32. 



Mandibles strong and sharp, without a free mem- 

 branous inner lobe Chemastochilixa, 



[p. 198. 



Division 1. CETONIINI. 



Section 1. CETONIINA. 



This section comprises the great majority of the known species 

 of Cetoniix.^, including all the largest and most handsome forms 

 and those in A\hicli are found united all the characteristic features 

 of the Subfamily, viz. the feebly chitinised mandibles, brush-like 

 maxilla), ascending mesosternal epimera, and pronotum (except in 

 DicranGceplicdus) sliding closely over the base of the hind body 

 without meeting any arresting ridge upon the scutellum or elytra. 

 In each of the three remaining Sections one or more of these 

 features is absent. 



The Cetoxiina are exceedingly homogeneous in all essential 

 points of structure, forming a series so nearly unbroken that a 

 satisfactory subdivision has never been attained. The frequently 

 great differences between the two sexes and the absence of marked 

 structural features in the females make it almost impossible to 

 define minor groups so as to include both sexes. I have divided 

 the genera belonging to the Indian fauna into the following groups, 

 but it should be understood that the characters used iu the tables 

 which follow are not to be regarded as fundamental or applicable 

 to forms from other regions. They are selected only as those most 

 easily available for the discrimination of the insects dealt with iu 

 the present work.
