both gave images in no way dififering from the usual form. Duration of 

 the chrysaHs stage in July and August 8 days. 



Nicippe is a very common species in this part of West Va. Its food 

 plant is Wild Senna, Cassia Marilandica, which grows abundantly, and the 

 butterfly is present in several successive generations and in overlapping 

 broods from early in May to winter. I have seen it on the wing 29th 

 April, and also in December, and am of the opinion that a few individuals 

 successfully hybernate. At almost any time eggs and larvae can be found 

 on the Senna leaves, many eggs perhaps dotted over the surface of a 

 single leaf and mostly the under surface. On one occasion I noticed a 

 butterfly just from chrysalis standing by its empty shell, on a stem 

 of Senna, and near by were fresh-laid eggs and newly hatched larvse up to 

 mature larvae. I recorded at the time that there were about forty larvae 

 on one stem. The larvae are very nearly the color of the leaves, and 

 usually may be found, when at rest, lying full length along the mid-rib on 

 upper side. 



The butterflies differ much in size and color. The normal color is 

 deep orange, but I have taken males of all grades up to clear sulphur 

 yellow, with no trace of orange. The females also are often nearly yel- 

 low, but I have seen none which had not a little orange in the disks. 



Nicippe is found over all the Southern and Western States, on the 

 Pacific coast, and so to the tropics, avoiding the highlands. It is common 

 about Pittsburgh, Pa., and is occasional as far to the eastward as Massa- 

 chusetts. In 1877 I saw a single one flying near the coast, below Boston.

 hind margin. Secondaries rounded, not prolonged at the anal angle as in 

 E. Pylades, nor excavated opposite the cell as in most of the Nisoniades.
