This singular and aberrant genus seems to be allied to Idio- 

 stolus. Berg, from Basket Island (Cape Horn), but I think they 

 cannot be identical. In bis description of Idiostoliis Professor 

 Berg says that there is no hamiis to the wings. But if in this 

 genus the hamus has the same unusual place as in Trisecus, 

 Professor Berg has possibly overlooked it.
