Differing from the other species of the genus Metacanthus Costa 
(= Megalomerium Fieb.) hitherto described, by the three subbasai tubercles 
of the pronotum. It approaches the most M. pusillus Hory. from Java, 
but differs from it by the black throat, the more prominent tylus and 
the black annulation of the antennae being confined only to the basal 
half of the first joint ; these black rings as well as those of the legs are 
narrower and more distant from each other than in M. pusillus. 
Our type-specimen of M. pusillus being picked just before the 
basal margin of the pronotum, I am unable to decide whether its pronotum 
is provided or not with a median subbasai tubercle. I think, however, 
that the above mentioned differences will prove sufficient to distinguish 
the two species.
