the third dorsal a little oblique forwards ; the third dorsal and the fourth 
costal are in the ciliæ. There is a silvery white apical spot. The dorso- 
apical portion suffused with brown : costal and dorsal ciliæ brown : apical 
ciliæ silvery white, with a dark brown oblique streak (hook). Hinder 
marginal line at the base of the ciliz brown. Under surface and legs 
silvery or opalescent, stteaked and banded with golden brown. Adar ex. 
scarcely 74 inch. 
It belongs to Zeller’s section A, having nine veinlets given off from the 
discal cell ; has the “ hook” in the apical ciliz ; the scales of the vertex 
are not appressed, and, like those on the under surface of the second 
joint of the labial palpi, they are long and loose. 
It is a very handsome insect, and the ornamentation seems to be 
intermediate between G. onovizdis and G. pavoniella, as figured in Stainton’s 
Nat. Hist. Tin., v. 8, plate 5. The wings are rather more golden than in 
ononidis, and not so much suffused with brown along the centre, and it 
lacks the drown basal and first dorsal white streak represented in that 
species. The wings are not so much golden as in pavoniella, but it has 
the basal streak exactly as in that species, and the apical hook ; but it 
lacks the last small dorsal streak or spot of that species, and has the apical 
spot as in oronidis, whilst pavoniella has none. 
The larva is yellowish, and does not change colour previous to pupa- 
tion. It mines the leaves of the Virginia Plantain (Plantago Virginica) 
in September, October and November. ‘The mine is at first narrow, 
winding and linear, filled with frass, ending in a large bladder-like mine, 
the upper and lower cuticles being puffed out. The linear portion is only 
visible under the lens. It remains in the mine until it is ready to become 
a pupa, which it does in a small #zdus on the ground, and the imago 
emerges in less than a week. Kentucky. Common. 
Gracilaria 12 lineella. NN. sp. 
Palpi and legs white, flecked and spotted with blackish on their outer 
surfaces. Antenne pale greyish, annulate with pale fuscous. Head and 
thorax greyish-white mixed with fuscous. Anterior wings, to the naked 
eye, pale greyish (which the lens shows to be the intermixture of whitish 
and fuscous scales), with fuscous spots and blotches on the disc. The 
posterior margin with twelve alternate white and fuscous streaks small and 
not distinct, except the tenth, which is situated beyond the apical third, 
and extends obliquely backwards to the costal margin,where it is confluent 
with the eleventh dorsal streak, which curves forwards from its base on the
