A few notes as to the habits and whereabouts of this inhabitant of the rapids of Niagara may perhaps be of interest to such collectors as may visit this locality the coming season. This interesting beetle being but rarely represented in collections, I felt induced to make extra exertions during a few hours sojourn there last August, to find it, and was finally rewarded by finding it in numbers. Although my time did not allow me to reap the benefit of my discovery, still if others are enabled to Profit by these notes, the result will be the same.

By turning over the small rocks which lie in the small rapids close by the Goat and Sister Islands, the flat, crustacean-like larvæ will be found in great numbers adhering tightly to the under surface in all stages of development, and it is here one would naturally look for the perfect insect, but only to be disappointed.
