Maceotomin^. 



In the more normal forms of this subfamily, the great 

 size and length of the third joint of the antennae is the 

 most marked character. As limited by M. Lacordaire, 

 none of the Macrotominm are found in Australia, the 

 greater part belonging to Asia and Africa. There is only 

 one species in the collection.
