The posterior legs are long, robust, and hollow, furnished with two pair of spurs, a longitudinal suture, and a tuft of long silky hair arising at the base, and concealed in the tibia when at rest. Many Lepidoptera have their legs, especially the posterior, furnished with brushes of hair, but in no instance are they more curiously disposed than in Alcis. It is conjectured that they are designed to assist in balancing the body when in flight.

A. scolopacea is a native of Jamaica; measuring nearly three inches and a half between the tips of
