cation that the tjrpe came exactly from La Morelia, which is surely not the only place where 

 this species occurs. If a species from an unknown place is divided into various geographical 

 forms, and no tjrpe-specimens exists to show which of these subspecies it is, the Gordian knot 

 must bo cut and we must restrict the first name to some locality or area, but otherwise the 

 arbitrary practice of proposing an exact " typical locality " cannot be accepted, unless there 

 is some indication that the type was obtained there. Thus the " make " of trade-skins can 

 decide that a species came from the province of Rio, from Guatemala, or Colombia (Bogota 

 collections !), but not that it came from a certain town or village). 



Type : Trade-skin (evidently adult) from a Bogota collection, purchased 

 from Mantou in Paris.
