Coleopt. x, 1874, p. 175. 
Type, M. intermedius, Suffr., from Borneo. 
Range. India ; Siam ; Borneo ; Sumatra. 
Short and ovate. Antennae short, not extending to hind margin 
of thorax, basal joint slender, club-shaped, second ovate, following

Monachus and Cryptocephalus ; distinguished from both by the 
shape of the prosternum and the dilated terminal joints of the 
antennae.
