Ik-ad in front with rather erect hairs, at the haek smooth. Antennic 

 shorter than the anterior wings, Ihe eije-cap of lite banal joint lnr(j(\ 

 Labial palpi short, drooping;. Anterior wings slightly pointed, not 

 caudulate, the posterior nnrrow, lanceolate. \\\ the anterior wings 

 there are only four simple longilndinal veins, thus no discoidal cell. In 

 the posterior wings the median vein divides into three branches. 



Little is yet known of the habits of the insects of this genns, 

 and the larvpe of none liave yet been discovered. We have only 

 three British species, which are readily distinguished.
