central portion obsolete; pronotum punctate; elytral intervals bi- 

 seriately tuberculate and dorsal surface largely alutaceous. Males of 

 this species can be differentiated from the females by the emargination 

 of the last abdominal segment, the pronotum and legs being similar in 

 both sexes. 



0. tuberculifrons is found most commonly in sandy localities from 

 Connecticut to Florida and west to Texas, Oklahoma, and Kansas. 

 Specimens are readily collected by the use of sunken cans baited with 

 fermenting malt and propionic acid. Adults are attracted to human, 

 cow, and other types of animal dung as well as fermenting fungi or 

 other vegetable material. Depth of the adult burrows ranges from 

 2 to 3 inches in moist localities such as the Chilhowee Mountains of 

 Tennessee and from 6 to 7 inches in more xeric habitats such as South- 

 ern Pines, N.C. 



Brown (1926) stated that ''tuberculifrons is an eastern species 

 occuring in pine woods along the Atlantic coast from New Jersey to 

 Florida." However, he also found it in a small wood of blackjack oak 

 near Ripley, Olda.
