The female is similarly coloured to the male, but is usually 
more brilliant in colour, the abdomen being sometimes of a rich 
purple, owing to the beautiful iridescence of the short pubes- 
cence or pile which clothes it; the red margin of the abdominal 
segments of the male, as described by St. Fargeau, is attributable 
to the iridescence of the pile, and is most observable in sun- 
light.
