It is |i(>>>>>tlili' thut this furni, whiih Kuwcrt rcgartlt>(l as an aliiTration of P. duplicatus 

 (Har.) may be no more than a variety «if /'. fninisttclus. It differs from the hitter only in 

 being without punrture.s in the po.sterior angle.s of the pronotiim, in having the ]iuncture<i 

 area on the central area of the metasternum less .strongly marked, in having the puncture.>i 

 of the >eventh aiul eighth grooves of the elytra weaker an<l le.sj* distim-tly tran.sver»e, and 

 in having the posterior angles of the elytra polished instead of matt. The.se are much 

 the .same characters a.s those hy which Kuwert di.stinguishes this form from the form 

 which he regards as the typical dupAcatus, a species which I have not .seen.

This species superficially re.sembles Prntalnhuji fiarba'us. The antennae have, however, 

 only four lamellae ; the anterior margin of the hea<l is nppro.ximatelv .straight in the midtlle ; 

 the puncturing of the sides of the prothorax is somewhat !e.ss exten.sive ; the lateral areas 

 of the meta-sternuni are hair)' : and the punctures of the lateral groove-n of the elytra, 

 though very strong, are not transverse.
