Face with cone of scales or almost smooth. Palpi moderate or 

 rather long, porrected, rough-scaled. Antennae in ^ ciliated, 

 sometimes serrate-dentate. Thorax glabrous beneath. Posterior 

 tibiae with all spurs present. Fore wings in ^ with strong hair- 

 prncil lying near inner margin from base beneath, sometimes 

 partially clothing 1 b ; areole double. Hind wings with 8 anastom- 

 osing with cell from near base to beyond, middle. 



Also an offshoot from Hydriomena, characteristic of 

 the European region and North America.

22. Plemyria, Hh. 



Face with slight cone of scales. Palpi moderate, porrected, 

 rough-scaled. Antenns in $ ciliated. Thorax glabrous beneath. 

 Posterior tibiae with all spurs present. Fore wings with areole 

 simple. Hind wings with 8 anastomosing with cell from near 

 base to beyond middle. 



A genus of some extent and very wide range, most 

 numerous in South America, elsewhere subordinate to 

 Hydriomena, of which it is a development. The con- 

 nection is very close, and the terminal European species 

 must be extremely near the ancestral form ; hence the 

 genus probably originated in Europe.
