There are two forms of this insect which seem always associated together in the same 
locality. In one, the marks of the secondaries beneath are narrow and the spot nearer 
the anal angle has a single light centre; on the upperside the red of the secondaries is 
less produced: this is the true C. pitheas of Latreille. In the other form the dark 
marks of the secondaries beneath are wider, the anal spot contains two light marks, and 
the red of the secondaries above extends further toward the outer margin. Both 
these forms occur in Central America. 
Though not yet met with in Costa Rica, C. pitheas is not uncommon in Nicaragua, 
where it was taken by both Belt and Janson. Salvin also captured some specimens in 
the month of April 1873, in the scrubby forest in the outskirts of the seaport of San 
Juan del Sur. 
In the State of Panama it is not uncommon; but in Northern Colombia it occurs 
in abundance, and thence southward to Peru.

Callizona, Doubleday, Gen. Diurn. Lep. p. 246 (1850). 
As Doubleday remarks, the single species composing this genus seems somewhat out 
of place in the position he has assigned to it, and where subsequent writers have been 
content to leave it. As will be noticed below, there are characters in the secondary 
male sexual organs which suggest an affinity between Callizona and Melitea. Godart 
placed C. acesta in the genus Argynnis, which allocation Doubleday admitted to be not 
without justification. Our observations, therefore, tend somewhat to confirm this view. 
On the other hand the pupa, according to Stoll, has appendages like those of Ageronia, 
a fact of undoubted weight. 
In Callizona the subcostal nervure of the primaries emits two branches before the
