The Lizards of Kansas 19 
moved from the sides of large boulders, which they 
scaled with ease. A few of these swifts were taken from 
prairie grass near a rock ledge in Ellsworth County, and 
several persons have found the chalk beds of Trego and 
Gove counties to shelter many specimens. The sand 
dunes of Stafford County, though probably less favor- 
able to this subspecies than to Holbrookia maculata ma- 
culata, have their quota of both species. All yellow- 
banded swifts taken there were removed from the sur- 
face of the ground, with the exception of five, which were 
captured upon the sides of a farm shed which was coy- 
ered with sanded tar paper. 
The yellow-banded swift feeds upon a large variety of 
small insects, particularly beetles, ants and grasshop- 
ers. 
Little attention has been given to the study of the life 
history of this lizard. Shufeldt (1885) found seven eggs 
in the uterus of one female. Strecker (1910) reported 
two females with eggs, one having six, the other eight. 
Taylor (unpublished) stated that ‘‘Females taken in 
July had not yet deposited their eggs. One very large 
specimen was found to contain fifteen.’? The writer has 
found seven Kansas females to contain lots of seven, 
seven, seven, eight, nine, nine, and eleven eggs, respec- 
tively, giving an average of eight eggs per female. On 
June 12, 1926, a specimen laid six white eggs which 
measured six by ten millimeters in size. 
Distribution in Kansas—S. undulatus thayerii is gen- 
erally distributed over central and western Kansas. 
Further collecting in the counties in that area will very 
probably add to the county distribution list indicated by 
the following map.
