that the two species encroached on each other's territory more 

 than a few yards. 



Canthon Iccontei Horn is an interesting little species which 

 makes a well in the sand one-quarter inch in diameter and three 

 inches deep, close to or under a fresh rabbit pellet, drops the 

 latter to the bottom of the pit and there bores to its center and 

 lays the egg. This small shiny black species when disturbed 

 will fold its legs and have the appearance of seeds of the sur- 

 rounding weeds and is apt to be overlooked. 



Bradycinctus fossator Hald. The first impression at sight 

 of the burrow of this species is as though a carpenter had used 

 a half -inch auger and left the chips around the hole. The 

 great burrowing crickets of this section, having similar holes, 

 caused considerable extra work until experience enabled me 

 to separate each at sight. The use of a spade a number of 

 times failing in results, a dry weed stalk was pushed down the 

 pit and the sand dug away on one side within two inches of 

 the stem or hole and the rest carefully removed with the fin- 

 gers, when the beetle would be found at the bottom, some- 

 times both sexes being present, at other times either sex singly. 

 The well would be perfectly straight and about fourteen inches 

 deep. The species is not scattered bnt usually restricted to small 

 areas in apparent colonies. A strong light placed on the sand 

 near the burrows yielded from three to five specimens per 

 evening. 



Strategus mormon Burm. is a true sand hill species, some- 

 what restricted as to area, occurring in but a few acres, but 

 there in abundance. It bores a well one inch in diameter and 

 eighteen inches deep, then fills in with layers of old dry horse 

 manure, which is about a year old and in which the eggs are 

 laid. Judging by the different stages in which I found speci- 

 mens I suspect it takes three years in the larval state for devel- 

 opment. 



Strategus mormon and Phanacu.v diffonnis both seem to 

 miss the old buffalo chips and do not seem to thrive as well on 

 the manure of domestic animals. 



All the species were taken from the middle of May through- 

 out the month of June.
