The above is a very fine foreign example of a genus 
containing a good many British moths, which, ac-

posterior legs are long, robust, and hollow, furnished 
with two pair of spurs, a longitudinal suture, and a

more curiously disposed than in Alcis. It is con-

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