Remarks. — -The nominate form of this subspecies has the apical 

 streak of the forewing continued to the upper of the tornal streaks and 

 connected to it. The specimens without this connection received the 

 name potamites Walsingham. They have the terminal streaks of the 

 forewing narrow, and some rotundate spots located internad of streaks. 

 The name geminipucta Walsingham was given to an undoubtedly 

 aberrative, narrow-wmged female specimen representing an extreme 

 of the form potamites. All these forms intergrade with each other, 

 and thus hardly deserve separate names. Even Walsingham him- 

 self, the author of potamites, was probably not quite certain of the 

 characters distmguishmg it, and identified some paratypes of this 

 "species" in the collection of the U.S. National Museum (nos. 5962, 

 5964, and 66229) as being rivularis. The photographs in the present 

 paper give an idea of the variation of the subspecies in Central 

 America and, besides the intergrading specimens, also include some 

 forms slightly deviating from the average limits of this variation.

Plate 28 



Female. — Antenna black with scattered, whitish scales on scapus. 

 Labial palpus black with cream-white color starting at base laterally 



* One other female specimen in the British Museum (Natural History), labeled 

 "Panama Crowley," belongs to the subspecies volcanica and probably originates 

 from South America.
