FIDONIA ATOMARIA Gn. 
The type of this species (Sp. Gén. X, 155) is at Paris and bears a 
label by Mr. Th. Mieg stating that the type locality New Holland 
as given by Guenée is incorrect and that the species is N. American 
and the same as fa.coni Minot, over which it has priority. As far as 
we could judge this is correct although we had no actual specimens 
for comparison, 
EUFIDONIA FIDONIATA WIk. 
The type is a ¢ with very heavy subterminal and terminal bands 
on primaries leaving a white wavy s. t. line; notataria Wlk. is a @, 
white, speckled heavily with light brown, with less distinct banding 
on primaries than the preceding, but heavier markings on secondaries ; 
this may be merely a sexual difference. Discospilata Wlk. seems to 
be a northern form; we have 3 2’s from Canada corresponding with 
the type; they are white with the brown markings much deeper black- 
brown than in notataria although the style of maculation is similar. 
In a variable species like this breeding is necessary to determine the 
specific standing of the forms. 
MELLILLA INEXTRICATA WIk, 
The synonymy of the genus Mellilla, as it stands in our lists, is 
much muddled. The type of inextricata Wilk. from Florida is worn 
but the secondaries are pale orange blotched with purple-brown form- 
ing two semi-parallel bands across wing; we have seen two specimens 
like it. The species commonly known under this name is ranthometata 
WIk. with chamaechrysaria Grt. as a synonym; both ¢ types are poor, 
but show distinctly the straight post median line followed over the 
remainder of the wing by a dark shade containing black blotches. 
From the description rilevaria Pack. would also be a synonym, merely 
differing from typical specimens in that the subterminal blotches are 
wanting. We have bred quite a series of this species from larvae on 
honey-locust ‘and find this feature variable. The name snoviaria Pack. 
applies we think to the summer form of the same species in which the 
heavy subterminal dark shading is almost absent and the black blotches 
show more clearly; the spring ¢’s, and to a lesser degree the 2’s,
