Readers will have noted that, beginning with the January number, a better grade of paper has been adopted for the Canadian Entomologist. This step was taken in order to meet the demand for a better reproduction of photographic illustrations, in which a good deal of important detail was lost with the paper formerly used. It will we think be generally agreed that the new paper is a great improvement.

However, we should like to take this opportunity of making some general observations on the illustration of entomological papers.
