210 THE CANADIAN ENTOMOLOGIST. 
I never met with any inconvenience from ants as Mr. Mead has, but I 
have met with a rather serious one (because it is almost ‘‘ morally” im- 
possible to remove it) in the various species of tree toads. Beautiful 
little fellows, with eyes like diamonds, that will mount your garden fences 
and snap up unwary Heterocera without compunction. Rather annoying 
but of course you cannot drive them away. 
Mr. Mead says nothing about a light. I advise a square tin lantern 
with a good reflection and some means of shutting off the light, which 
should be turned on suddenly. A Bulls-eye concentrates the light too. 
much. Strap the lantern around your waist. I like a little rum in the 
molasses for the moths, and a little for myself.
