Group MONOHAMMINI. 
This group in a natural arrangement would comprise at least two of Lacordaire’s 
“groupes,” viz. Monohammides and Batocérides, the degree of completeness of the 
cicatrice of the antennal scape, on which the author of the ‘Genera’ relied for the 
separation of the two, proving to be much more irregular than he believed it to be. 
The group contains a large number of genera, consisting nearly all of large and 
beautiful species ; but they are chiefly confined to the tropical and warmer regions of 
the Old World, being especially abundant in the Indian and Malayan regions. Out of 
fifty known genera, only six occur in Tropical America; and of these three are almost 
restricted to Central America and the neighbouring countries north and south.
