Remarks: In general Bothynus mono LeConte is a smoother, 

 slightly longer, and darker species than gibbosus, which it otherwise 

 resembles. The smooth outer face of the anterior tibia (fig. 6/) is 

 a character shared with neglectus LeConte, but whereas inorio is more 

 finely punctate and of smoother appearance than gihbosus, neglectus 

 is much more coarsely punctate and rougher than gibbosus. The 

 male genitalia of morio LeConte appears to be nearly identical with. 

 that of gibbosus (DoGecr) and the subspecies obsoletus LeConte. 

 See figure 5. It is attracted to lights. 



Some specimens of morio from Miami, Fla., have punctures much 

 coarser than usual, but they still appear smootlier than gibbos^is 

 and the foretibiae are smooth as is usual in tlie species. Perhaps 

 these specimens provide an example of character displacement.
