496 J. C. BRANNER — GEOLOGIC WORK OF ANTS 



Grosso where it joins Bolivia, tells me that he has seen at night many of the 

 nests of white ants that have been abandoned by the ants themselves entirely 

 covered by fireflies that come from the small openings over the whole surface 

 of the ant-hill. Is it possible that the fireflies select these abandoned ant- 

 hills as places in which to grow their larvae? . . . Unfortunately I have 

 never observed anything of the kind hereabout, though I have been interested 

 in the subject in order to furnish you information."
