Antennae with an abrupt, obconic, slightly compressed club ; 

 palpi short, the basal joint long, recurved, cylindrical ; second 

 about half the length of the first, the terminal one slender, 

 short, linear, as long as the second. Wings thinly clothed 

 with scales, especially in the female, which is almost sub- 

 diaphanous ; cells broad, of about equal length on the fore- 

 and hind-wings ; sub-costal nervure four-branched, the third and 

 fourth branches forming a rather wide fork ; upper discoidal 

 nervure emitted about half-way between the cell and the base 

 of this fork ; fringes almost absent ; larvae gregarious, feeding 

 under a web when young. 



I consider that there is but one species of this genus, for the 

 Asiatic species which have been associated with it by various 

 authors are much more densely scaled, and have well-developed 

 fringes, and appear to me to be much more closely allied to 

 the genus Metaporia,
