Having read in the Report of the Entomological Society of Ontario for 1877 an article by Prof. J. T. Bell, of London, Ont., entitled “How to Destroy Cabinet Pests,” I thought it might not be unprofitable to record my own observations on Dermestes.

Early in the summer of 1876 I captured four beetles, three males and one female, and placed them in a glass jar with a piece of the meat on which I found them feeding. I observed the female deposit a number of eggs on the meat, but before any were hatched I left home, and was absent about five weeks. On my return I found a large and flourishing colony of larvæ, most of them full grown.
