108 NOTES ON AUSTRALIAN COLEOPTERA, 



forming a group distinguished by the combination of 9-jointed 

 antennae, comparatively short hind coxae, and very strongly bifid 

 claws. This little group seems to be confined to Northern Aus- 

 tralia, and occupies in my tabulation (loc. cit.) lines 10-21 on 

 p. 1331. I propose now to substitute the following for the 

 contents of lines 13-21 in order to include the additional species, 

 but I regret that I must drop H. corpulentns, Macl., oat of this 

 revised table, as I have not an example of the insect before me ; 

 at the time of my drawing up the original table I had a type lent 

 me by Sir W. Macleay and since returned. From memory and 

 description, however, I think it is distinguishable from all the 

 species included in the following table by the character referred 

 to in its name — viz., its short broad form ; it is certainly not 

 identical with any of them. 

 G. Front outline of clypeus not evenly 

 rounded (i.e., more or less truncate or 

 sinuous). 

 H. Elytra evenly punctulate. 



I. Uppermost tooth on margin of front 



tibiae well defined protervus, Blackb. 



II. Uppermost tooth on front tibiae 



almost obsolete hreviceps, Blackb. 



HH. Elytral punctures subseriate and 

 with unpunctureJ spaces of various 

 area. 



I. Clypeus much more closely punc- 



tured than forehead ; size mode- 

 rate merus, Blackb. 



II. Head somewhat evenly punctured ; 



size very large piceo-niger, Macl. 



GG. Front outline of clypeus quite evenly 

 rounded. 

 H. Punctures of prothorax excessively 



coarse arcamis, Blackb, 



HH. Punctures of prothorax very much 



finer rugosipennis, Macl.
