AMPHITHERID^. 



I constitute this new family for the genera Amphithera Meyr. 

 (=Zonoj)S Turn.), A(/riofhera Meyr., and the new genus described 

 below. These have the following characters in common : — 



Head densely rough-haired on crown, face smooth ; tongue 

 developed. Antennae much over 1, basal joint with pecten. Labial 

 palpi long, curved, ascending, somewhat roughened anteriorly, 

 pointed. Maxillary palpi- obsolete. Posterior tibi;e thinly clothed 

 with long hairs above, densely rough-haired between spurs beneath. 

 Forewings with 1 b furcate, 2 from angle, 7 and 8 stalked or 

 coincident, 7 to costa. Hindwings over 1, trapezoidal, ai)ex pointed, 

 termen strongly sinuate, tornus prominent ; 5-7 nearly parallel. 



Specially characterised by the peculiar form of hindwings ; two 

 of the three genera also possess a unique eye-structure. The group 

 is a development of the Plutellida' ; it is distinct and remarkable.
