We notice a much greater similarity of food habit in the southern 

 species than in the northern — oak, hickory, and persimmon being the 

 principal elements of the food of eight of the ten such species whose 

 food we know, the ninth being the peculiar fruit-tree species forbesi, 

 and the eleventh, veliemens, which we have taken only at lights. 

 Furthermore, jervida and hirticula, which are southern and central 

 species, are both oak-hickory May-beetles, fervida being especially 

 common on persimmon also. The four northern and central species, 

 on the other hand, ilicis, fusca, inversa, and drakii, are all of a differ- 

 ent food habit from the foregoing group, ilicis most abundant on oak 

 and elm, fusca and drakii rather general feeders, and inversa espe- 

 cially abundant on the willow, elm, and hickory.
