$ 14 9 fairly uniform in marking’s and shcnving no markeil departure from 
the parents. Figs. 56 to t)i. I’l. II show the range of variation in the series. 
A wifier variation than this occurs among these moths as shown by a 
selected series of captured specimens sent me by Mr. Dodge in which several 
s|)ecimens are immaculate white ( t'lir fuh'icosta ) and others intergrading be- 
tween fuhicosta and reversa. 
In this species and in Iccoutci both of which have immaculate forms, the 
examples I have examined indicate that the immaculate specimens are more 
common than those that can be really classed as intergrades, d his suggests 
the theory that the immaculate forms are really "mutations'' in the sense in 
which De \’ries uses the word. This is further supported by the following 
case. 
H. lecontei var. vestalis 
A ca])tured 9 vestaUs (tig. I’l. II ) sent me by Mr. Dodge iri 1904 laid 
fertile eggs from which were reared 16 and 10 9 . Of these to S and 8 9 
were like the mother, immaculate. (See tig. 70, I’l. III. GS and 2 9 were 
marked with brown, showing patterns referable to var. niiUttiris (fig. 74) var. 
confinis (fig. 75) and var. harrisii (fig. 72). 
H. lecontei var. harrisii Dyar 
A captured 9 harrisii (I’l. 1, fig. (12) sent me in 1904 by Mr. H. D. Merrick 
from New Hrighton, I’a., laid eggs from which were bred 3 <? and 3 9 (see 
PI. II, figs. 63-68). These showed ipiite a range for so small a series, contain- 
ing forms referable to vars. harrisii, coufinis and militaris. 
Typical lecontei Boisd 
It seems unfortunate that the ty])e of a species having so many varieties 
should have been based upon one of tbe least common of its forms. (See ac- 
companying figure which is a reproduction of Boisduval's illustration of his 
type. ) This form is very rare among collections I have examined. ( )nly two 
or three moths of those obtained in tins locality come very close to it. Figs. 
3 and 4 PI. II bred from larvae taken near Claremont are nearest to the type 
of any in my collection.
