BEETLE GENUS ONTHOPHAGUS HOWDEN, CARTWRIGHT 37 



Type locality. — Crescent City, Fla. 

 Specimens examined. — 159. 

 Distribution. — (See fig. 5.) 



Florida: Crescent City, 4 mi. north of High Springs, Gainesville, Leesburg, 

 Lutz, Miami, Stemper. south Carolina: Tillman. 



Remarks. — This moderate-sized species is quite distinct from other 

 American Onthophagus. It can be separated by its uniformly shining, 

 dark brownish-black dorsal sm-face, the presence of small tubercles 

 with setigerous punctures at their bases on the head and near the an- 

 terior pronotal angles, tlie smooth shining disc of the pronotum, the 

 smooth margin of the fore tibia between the four teeth, and the lack 

 of pronounced sexual differences, the male majors having only a widely 

 rounded pronotal protuberance and the forelegs being the same length 

 as those of the female. Pronounced tubercles, setae, and punctures 

 on the head, pronotal angles, and elytra will separate typical poly- 

 phemi from the west Florida, Alabama, Mississippi subspecies sub- 

 sequently described. 



0. polyphemi polyphemi and its subspecies have been collected only 

 in the bmTOws of the gopher tortoise, Gopherus {Xerohates) polyphemus. 

 Adult specimens have been collected in March, June, July, and August, 

 appearing freshly emerged in March. Hubbard (1894, p. 305) stated, 

 "I did not find this beetle in the few galleries examined in the winter, 

 and it was probably in pupa at that season." In July it was not rare.
