no known genus. It seems to me to come nearest to Amphimenes 
Bates which I know only from the description. The new genus 
differs from Amphimenes by the hemispheric eyes, by the elytra 
being much broader than the prothorax and spinous on each 
edge of the apical truncation, and by the less elongate tarsi. 
Oxydontus Chaud. also seems related to it, but shows an ex- 
tremely long middle tooth on the mentum, thicker labial palpi, 
and unspined apical truncation of the elytra. 
The form of the ligula in Hoplomenes shows a great resem- 
blance to that in the Tetragonoderidz,’ but among these no one 
genus has similarly pectinate unguiculi.
