The type of Tychreus {T. camelus) has two large median 

 tubercles on the elytra, and is of an indefinitely varied 

 greyisli colour ; it has, therefore, a look quite distinct from 

 the above, with which, however, it appears to be fairly 

 congeneric. The last joint of the funicle, as in the last genus, 

 appears to form part of the club, but the line of separation is 

 sufficiently clear.
