The colour of this species is smooth shining rust-red, some- 

 times deepening into reddish-black. There is a pit on either 

 side of the head, the elytra are tliickly punctured and striated, 

 and beneath it is rust-red- This Beetle has been chosen 

 because it is the largest of the genus, sometimes exceeding 

 one-sixth of an imli in leiigtli. The rather peculiar antenna 

 of this genus is shown at Fig. a of the same woodcut.
