yellow to white; it appears to be independent of the length of the 
period of larval and pupal development. The bands of males, and of 
females that are not already white, always fade to white over a 
period of approximately two weeks under natural conditions. Fad¬ 
ing appears to be related to light exposure; it can be induced in dead 
specimens exposed to sunlight (Taylor, 1973), but does not occur in 
museum specimens protected from light. 
A. fatima shows marked variation in the extent of red coloration 
on the hindwings, with an increasing expression of red on the hind 
margin of the hindwing, in the northwestern part of its range. Hoff¬ 
mann’s “colimensis” (Figure 5) represents the extreme expression of 
red in A. fatima. There is an intriguing resemblance between this 
variant of A. fatima, and the banded “roeselia” of A. amathea, at 
the northern and southern extremes of their respective ranges.
