ANTHOCHARIS II. 



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.
