240 Plantce Lindheimeriance. 



mention is several times made of " deserted ant-hills." Further 

 investigation has shown that these hills are formed by loose 

 earth brought by these ants out of their subterranean exca- 

 vations. These consist of oblique tubes, some eight or nine 

 inches wide, others only half an inch in diameter ; they 

 sometimes reach a depth of thirty or forty feet. In the 

 greatest depth are their granaries, containing often many 

 bushels, and it is said, even wagon-loads, of corn and other 

 grain. These ants are also common about New Braunfels, 

 and this or another species has occasionally been found to 

 be quite destructive to Mr. Lindheimer's collections."
