THE ANT-LION.

with rank vegetation as to be quite dark, access is 
with some difficulty obtained to the basal floor of 
the mill, which is covered with a layer of impalpable 
sand, the residuum, no doubt, of the water that shot 
upon it when the wheel was in operation. The 
flooring planks of the upper level have been removed, 
leaving only the rafters ; and the walls of the mill con-

that sufficient light descends to the lower level not- 
withstanding its depth. Here I found many little 
conical pits in the fine sand, which upon examina-

a species of Ant-lion [Myrmeleon), and inhabited by 
them. The appearance of the crafty insect, its mo-

tubular jaws expanded to their utmost stretch, and the 
broad body concealed in the sand ; the alertness dis- 
played when an unfortunate ant slipped over the edge, 
the struggles of the prey to escape, the reiterated 
showers of sand vigorously cast up from the head of the 
expectant Giant Grim, and falling on the miserable 
victim, and the slow but sure sliding down of the 
latter, until the formidable jaws closed upon it; — 
I observed with intense pleasure, not only for the 
interest attached to so curious an example of insect 
cunning, but also for that of repeating observations 
long ago made in a distant part of the world, and, no 
doubt, on another species. The manners of these 
Jamaican Ant-lions agreed minutely with those of 
the Myrmeleon formicarius of the South of France, 
as recorded by the accurate Reaumur. 
The singularity of the spot chosen in this case for
