of forceps) it would turn on its back and fight furiously. A 

 pentatomid bug which it once seized in its jaws caused the 

 beetle considerable inconvenience, inasmuch as for a long time 

 thereafter it attempted to rid itself of the evil odor of the bug, 

 and remained with its mandibles deeply inserted in the soil. 



A stone being placed on its domain it made a hole beneath 

 it and came to sally forth with some confidence when aroused. 



LOCATION OF LARVAL BURROWS OF A. CYLINDRIFORMIS Say. 



The larvae of this species greatly resemble in structure and 

 general habits other larval forms of the family Cicindelidae. 

 Their burrows were found widely distributed in western Kan- 

 sas, and were rather numerous in Wallace, Wichita and Mor- 

 ton Counties. 



They usually occurred in colonies of from two to eleven, the 

 individual burrows being close together, often not more than 

 one and one-half inches apart. Usually a colony can be cir- 

 cumscribed by a ten inch radius. 



We found .in general two sizes of burrows, one small and 

 containing larvae not over one-half inch long, and the other 

 containing larvae about two inches long. One small burrow 

 which we excavated was about four inches deep and had a 

 diameter of one-sixteenth of an inch. The larger ones were a 

 little less than one-half inch in diameter and about thirty inches 

 deep. The rim was slightly elevated above the surface or sur- 

 rounding level, and the entrance perfectly circular. The bur- 

 rows have quite a characteristic way of going nearly straight 

 down for about eighteen inches and then, turning to an angle 

 of forty-five degrees downward, proceed about eighteen inches 

 farther. This lower portion has a tendency to be feebly spiral. 

 (See PI. II, Fig. 16). The burrow for the last eight or ten 

 inches is quite noticeably enlarged, especially laterally, and the 

 extreme end is invariably tightly packed with the remains of 

 former repasts. (See PI. II, Fig. 14). 



The holes are generally located On the brow of a cliff, but 

 one colony, figured in PI. II, Fig. 12, was found in muddy silt 

 at the foot of a cliff-like bank, well below the recent flood level 

 of the stream. Still others occurred on the high plain some
