Two spcfimens (c?) from Green Island are in the Simsou Coll. num oerert 

 2482; these have altogether the facies of .9. convexus Chaud., but have the basal 

 angles of the prothorax more marked. It seems conspecific with S. convexus, but 

 I am not prepared to determine it. 



SiMODONTUS TRANSFUGA Chaudoir. 



I identify as S. transfuga, specimens in the Simson Coll. ("No. 3479") ; it 

 differs from A', amtralis Dej. by shape more elongate, more parallel; prothorax 

 less transverse, more narrowed to base, more shortly narrowed to apex (in S. aub- 

 tralis the prothorax is widest about middle, in S. transfuga a little before middle') ; 

 el>i;ra with humeral denticule more prominent, more opacjue in 9- S. murraiianus 

 Blaekb., very closely resembles S. transfuga. but has the humeral denticule of the 

 elytra less developed.

. SiMODONTUS AENEiPEXNis Chaudoir. 



Hab. — Brighton. Devonport (Simson): Stanley, King Is. (Lea). Also lound 

 in Victoria (Portland). 



Genus Prosopogmus. 



My idea of the genus Prosopogmus includes Chaudoir's subgenera Ceneus, 

 Uiirnwchihis, and Ophrijosternus.
