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.
