 type in Riksmuseum at Stockholm. 



Sir Gr. F. Hampson has overlooked the fact that Karsch, in his key 

 to the genera of (Hollaiidiidae) Arbelidae, especially states that the 

 fore wing has an areola (''Auhangszelle "). This being the case, 

 Arbelodes, Hamps., is not the same genus as Arbelodes, Karsch, and 

 must take the name of Ortharbela, Auriv. 



Arbelodes collaris is undoubtedly nearly allied to meridionalis, 

 Karsch, but can hardly be the same species, unless the description 

 was made from a very badly-worn specimen.
