 (Busck). Also one from Porto Bello, March, 1911 (Busck). 



A fine series from Costa Rica has been identified by Mr. Schaus as 

 PiesmojJoda columnella Zeller, but we have another similar species 

 with different male antemise, so named by Sir G. F. Hampson and they 

 can not both be Zeller's species. Zeller described from a female 

 from Colombia and his species is unrecognizable except by further 

 collections from the same locality.
