the surface is coriaceous and only visibly punctured at the sides. 

 The scuteUum is without distinct punctui'es and the elytra are 

 ]ninctured in rather indistinct rows and rugose at the apical 

 luargnis. The pijgidium is transversely rugose, the sides of the 

 metasternwn coarsely punctured, and the abdomen almost smooth. 

 The sternal process is flattened, curved and blunt. 



(5 . There is a vestige of a lateral tooth to the front tibia and 

 the abdomen is lightly channelled beneath. 



2 . The pygidium is slightly setose.

This beetle sometimes appears in enormous luimbers. Mr. H. 

 L. Andrewes has usually found it in Blue Gum trees {Eucalyptus 

 fjlohulus) flying about the tops or feeding upon the sap which 

 exudes from tlie trunks, and he and ]Mr. Gray have seen the males 

 fiercely fighting together by butting each other with their horns. 

 Mr. Andrewes has more than once picked up detached heads 

 beneath the trees, possibly dropped by birds. 



Group 4. Cj:to\ii/)i:.s. 



This is the largest and most typical Group in the Subfamily. The 

 species are generally compactly built and most of them are covered 

 on the upper surface with a dull bloom and decorated with a white 

 or yellow powdery matter. The base of the pronotum has its 

 sides inclined, not in a transverse line as in the previous group, 

 and is excised in front of the scutellum, the posterior angles 

 of the prothorax becoming obtuse and sometimes completely 

 obliterated. The scutellum is generally blunt at its apex and 

 is never very acute, as in the remaining groups of Cktoniini and 

 the CiiEMASi'ociiiLiNA. The sexes are alike or distinguis'r.ed only 

 by slight external differences.
