II e = cratcsgella. l\f= truncicolella. Ill g = resinea. Ill h = 

 murana. Ill i = gracilalis. IV k = alpina. Four groups yet remain 

 to be separated : — 



Firstly — duhitalis and ingratella, tlie 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 cevihrce, hasistrigalis, Zelleri, and atomalis. Cemhrcs 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) ; phcdoieuca 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 difi'ering much from the former. 

 For the rest the reader is referred to the plate.
