The degree of interruption of the transverse apical blue on abdominal segment 8 of the males varies greatly, as 
in those from Los Amates, from a fine mid-dorsal black line to a mid-dorsal black band three-fourths as 
wide as the segment, or, in one example, the blue is broken by black into three spots. 
Variation at one locality, Los Amates, is shown in the following table :—
