II (9 = cratcegella. l\f=z truncicolella. Ill g = resinea. Ill h = 
murana. Ill ^■ =gracilalis. IV ^ ^ alpina. Four groups yet remain 
to be separated : — 
'Eirs.tlj—duhitalis and ingrafella, the latter being separable from the 
former by its larger size, broader fore-wing, and by the almost 
entire absence of black markings. 
Secondly — 5 species, of which amhigualis is the type, namely, that 
species cembrcs, hasistrigalis, Zelleri, and atomalis. CemhrcB is 
pretty easily distinguished from amhigualis by its fuscous tints 
and indistinct markings ; hasistrigalis by the first line being pro- 
duced along the costa, towards the base of the wing ; Zelleri by its 
large size ; atomalis by its small size. 
Thirdly — 3 species, of which mercurella is the type. From the latter 
ulmella is at once separated by the form of its renal stigma, which 
is as in group I h (cut C) ; plicBoleuca by the whiteness of its 
ground colour and pretty rounded fore-wings. 
Fourthly — 2 species, lineola and angustea, the latter having very narrow 
fore-wings, and otherwise differing much from the former. 
For the rest the reader is referred to the plate,
