Tlie 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 eyes in 

 front. The antennae are rather short and thick. Tho thorax 

 and elytra are similar to those of /?. malatcus.

I/ah. Malay Archij)elago, Tenimber. 



Several specimens of this, collected by Mr. Dohcrty, have 

 been presented to the British Museum by Mr. George Lewis. 

 It more nearly a|)proaches li. batchianus than any other 

 species I know; but its squarely-built form, with almost 

 straight sides to the tliorax making a nearly continuous 

 outline with the sides of the elytra, distinguish it from all 

 others.
