from the above mentioned genus. The peculiar coloration is abnor- 

 mal in this family. It was this, besides the short woolly body and 

 short broadly pectinated antennae, that most probably led Hiibner to 

 place it near Clisiocampa in his ' Verzeichniss.' " 



Dr. Packard was apparently unacquainted with the ? , which difilers 

 so strikingly from the $> that it might readily be mistaken for another 

 genus. In appearance it resembles Phragmatohia, the body being 

 nearly smooth, and the wings inclined to transparency. The 5 diifers 

 widely from Phragmatohia. 



The only American representavies of the genus are found in Cali" 

 fornia, and are remarkable for the extreme variability of their coloring, 

 scarcely two specimens, especially of the males, being exactly alike. 

 In this respect the genus resembles its close ally Leptardia, and the 

 determination of the species becomes a task of great difficulty and 

 uncertainty.
