ANALOGIES OF SCARABvEID^ AND CETONIAD^. 237 



precede all in genera, as well as species, and overwhelm 

 them with its numbers. In genera, the Geotrupince follow 

 them. The Dynastince and Aphodiince are about equal ; 

 and the Trogince are the lowest in the scale. In species, 

 their relative proportions are, Scarabceina, as 29 ; the 

 Aphodiince, as 7 ; the Geotrupince, as 3 ; and the Trogince 

 and Dynastince, as 2 each. [W. E. Sh.] 



(211.) Having now detailed the chief peculiarities 

 of the five great divisions in each of the typical circles 

 of this tribe, we may proceed to verify their accuracy ; 

 first tracing the mutual analogies they present to each 

 other, and then illustrating the subject further by com- 

 paring them with other and more dissimilar groups. 

 The annexed diagram will exhibit, in one view, the dis- 

 position we have now made of the whole. 



Aphodiina I \ Glaphyrina 



Irogince./ \Melolonthince 



This diagram at once exhibits both the affinities and 

 the analogies of the two typical divisions of the Lamel- 

 licornes. The first, or the Scarabceidce, are the Sa- 

 prophaga of MacLeay ; the second, or the Cetoniida, 

 are his Thakrophaga. Furthermore, the entomologist 

 will perceive that we have taken for granted eight out 

 of the ten relations of affinity exhibited in this diagram, 

 on the authority of the same author ; so that the ex- 

 tent of our alteration consists in separating the Dynas- 

 tince into two sub-families. The Megasomince thus
