70 Mr. E. Moyrick on the classification of 



18. Calocalpe, Tib. 



Face with cone of scales. Palpi moderate, porrccted, rough- 

 scaled. Antennae in S ciliated. Thorax glabrous beneath. Pos- 

 terior tibite in <? sometimes densely rough-scaled above, with all 

 spurs present, but in <? very short. Fore wings with areole 

 double. Hind wings in <? with deep fold along inner margin 

 beneath, containing large lateral hair-tuft posteriorly ; 8 anastom- 

 osing with cell from near base to beyond middle. 



A development of Hydriomena. Although a small 

 grouj), it ranges throughout Europe, Northern Asia, and 

 North America.

A development of Hydriomena, with some collateral 

 relationship to both the preceding and following genera. 

 Besides the two following Asiatic species, the Japanese 

 lucicolans, Butl., belongs to it. Staudinger has described
