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.
