The head of this insect is comparatively short and the 
posterior lobes are broad, very prominent, and appear rather 
flattened externally owing to the projection of the vee in 
front. ‘The antenna are rather short and thick. Thw thorax 
and elytra are similar to those of R. malaicus.

Several specimens of this, collected by Mr. Doherty, have 
been presented to the British Museum ie Mr. George Lewis. 
It more nearly approaches &. batechianus than any other 
species I know; but its squarely-built form, with almost 
straight sides to the thorax making a nearly continuous 
outline with the sides of the elytra, distinguish it from all 
others.
