Rancocas, N. J. They were commonly taken at the golf com^se and 

 along old sandy roadways which were not too well shaded. This 

 was the same type of habitat where Sim also found Bolboceras and 

 Eucanthus. Between Aug. 21 and Oct. 3, 1927, in this locality, Sim 

 was able to collect 75 specimens of tumefactum. 



In North Carolina, South Carolina, and Georgia, tumefactum appears 

 to be limited to the mountains and upper piedmont regions, while in 

 more northern states it can be found on the sandy coastal plain. 



Nothing is known of the larval food or habits. 



Ritcher (1947, pp. 11, 12) described a single larva of Bolbocerosoma 

 tumefactum collected near Dover, Del. I have already expressed 

 doubt over the speciiSc value of the vague differences between this 

 larva and that of jarctum. However, the broadly rounded labrum 

 may be a consistent difference. Additional larvae are needed to 

 decide the limitations of intraspecific variation.
