Passalus rhodocanthopoides (Kuwert).

 Xeleuopt rho<loc(inthopol(les. Kuwert, 1898. pp. 142- 11 3. 

 Several specimens from Peru (Cumbasa and the Amazon region). Length 24-25 mm. 

 A somewhat flatter insect than the preceding, with the inner tubercles situateil 

 almost vertically behind the outer tubercles but separated from them by a well marked 

 concavity. The posterior intermediate areas of the metasternum are coarsely punctured, 



> One of the .Mexican specimens has numerous small spines on these tibiae, and the Columbian specimen has them 

 numerous and very strong. The latter spwimen has the elytra more coarsely puncturetl than any other that I have 

 seen and may i>rovc to belong to a different species*.
