Habits of Some Burrowing Scarabaeidae (Col.). 



By REV. J. C. WARREN, Sylvia, Kansas. 



Here within a radius of two miles there are salt marshes, 

 alkali beds, black loam and sand hills, and on the latter the 

 species under consideration were found and observations made. 



Phanaeus difformis LeC. is found in sand hills only, always 

 choosing this sandy region to bore a straight hole almost paral- 

 lel with the surface, close to a fresh manure dropping. The 

 horn is used in lifting the sun-baked crust from these, also in 

 connection with the thoracic shield to press the sand in making 

 the pit; it is constantly used in boring and lifting, and is not 

 altogether an ornament as has been supposed. When coming 

 to the clay region the beetles will always turn back to the 

 sand. 



PJwnacns carnifcx Linn, is found in black soil only, always 

 choosing hard clay or sandy loam for its burrow, nearly at 

 right angles with the surface, and usually the pit is close to the 

 roots of a bunch of grass. An examination of the ground 

 where the sand and black loam come together failed to show
