terminella would have required. At some future period the dis- 
covery of other species perfectly agreeing with them in structure 
would render the construction of independent genera necessary. 
In @ratella the palpi are short, thick, and drooping, the antenne 
short and thick, and in the anterior wings the discoidal cell is not 
closed. In ¢erminelia the palpi are acute, filiform, ascending, the 
antenne are rather thick, and the anterior wings are not unico- 
lorous, but adorned with metallic spots. 
None of the larvee of these species are known, and, excepting 
modestella, all the species are extremely rare.
