90 BUTTERFLIES OF MAINE. 
The form violacea has dark points on the disk of the under 
side of the hind wings, and pale dusky spots and crescents 
along the outer margin, but not run together as in lucia. 
The form marginata has the terminal band on the under 
side of the hind wing as in ducta, but has the disk as in 
violacea. 
The form neglecta has the upper side of the hind wings 
paler than the fore wings; and the under side paler, and the 
the markings less distinct than in viéolacea. 
From the studies of Mr. W. H. Edwards on this species, 
it seems probable that there are two generations in Maine, at 
least in the southern part, that the spring brood has three 
forms, lucia, marginata and violacea —while the summer 
brood consists only of the form neglecta. It is quite possible 
that there is only one generation in northern Maine and that 
neglecta does not occur there. 
Mr. Edwards states that eggs laid by violacea on the 
flowers of dogwood (Cornus), in West Virginia, in April or 
early in May produce neglecta in June, but most of the pupe 
hibernate. 
The egg stage was five days, the larva twenty-four, and 
the pupa stage twenty-four. Mr. Edwards has strong reasons 
for believing that the. hibernating pup produce violacea 
again in the spring. He also states that the form pseudargio- 
lus, in West Virginia, lays eggs which produce the same 
form, but sometimes of a smaller size —the true neglecta ; 
but most of the larve hibernate and produce pseudargiolus 
again the next spring, as he believes. The fall brood of 
pseudargiolus lays eggs which after hatching and passing to 
the pupa stage, hibernate and yield vzolacea the next spring. 
Lucia has been observed laying its eggs on Cornus, in the 
spring, but its transformations are unknown, as are those of 
marginata also. 
The following food plants have been reported for the 
different forms : 
Actinomeris squarrosa, Actinomerts helianthoides, Apios 
tuberosa, Erythrina herbacea, Spirea salicifolia, Ceanothus 
americanus, Cornus and Ilex.
