flies, that it has been taken in the Mississippi Valley, outside of West Virginia, 
though it certainly must inhabit Ohio and the adjoining States. Mr. Butler 
credits the example in the British Museum to Illinois. Dr. Boisduval erroneously 
gives the habitat as Boston and vicinity. At Dallas, Texas, Genutia has.been 
taken by Mr. Boll in low and open-timbered land along the larger creek and 
river bottoms, in the months of February and March. It is found in certain 
spots in New Jersey, near Philadelphia, and in Maryland, near Baltimore, and I 
have taken it myself at Newburgh, N. Y., which is the most northern limit of 
its flight recorded. Here, at Coalburgh, I used formerly to see it, in April, flying 
about my garden, but of late years it seems to have disappeared. It flies low, 
swiftly, with a peculiar, tremulous motion, and is readily distinguished from other 
Pierids by this flight, as well as by the conspicuous coloring of the male.
