 The Australian species diflfers from the ordinary European forms 

 of the genus, and perhaps when more are known may be entirely 

 separated from it ; I have, however, for the present, made it into 

 a subgenus, of which I have given the following characters: — 



Subgenus Micromela. 

 Antennae subincrassatae, thorace vix longiorcs, articulo tertio 

 elongato, 3-10 brevibus, fere a>qualibus, graduatim incras- 

 satis, ultimo ovato, subacuminato. Palpi clavati, truncati, 

 articulis tertio et ultimo brevibus aequalibus. Corpus rotun- 

 dato-ovat\iin, convcxum ; thorax lateribus non incrassatus.
