Ettrynotus is distinguished from Pedinus Latr., to which it is 

 nearly allied, in having a much larger and more conspicuous la- 

 hrum, and a clypeus though emarginate not cleft. The four ante- 

 rior tarsi of the males, and not the first pair only, are dilated. The 

 thorax also is widest behind, whereas in Pedinus it is widest in the 

 middle.
