I think it very probable that the X. marginella of St. 

 Fargeau is a variety of the female of tenuiscapa, having a 

 little ferruginous pubescence at the base of the posterior 

 tarsi. A", latipes and A", tenuiscapa are two of the largest 

 species of the genus, and the sexes of each resemble each 

 other ; they are black, and the males of each have their 

 anterior tarsi dilated, yellow, flattened, and fi'inged with a 

 mixture of long yellow and black pubescence ; the male of 

 X. latipes sometimes has the clypeus and a spot at the 

 base of the mandibles yellow ; other examples have the 

 clypeus only partly yellow ; in others it is entirely black. 

 Both species have the eyes of the males large and approxi- 

 mating ; X. latipes is known by its antennre having the 

 scape dilated at the apex into a battledore shape, its base 

 being very much attenuated. The antenna of X. tenuis- 

 capa, male, has not a dilated scape, it is simply slightly 

 thickened from the base to the apex. The females are not 

 so readily separated : both have the abdomen somewhat 

 flattened and rather finely punctured, and fringed at the 

 sides with curled, black pubescence ; the colour of the 

 wings a^ppears to be a good specific character. The wings 

 of A^ tenuiscapa are brown-black, with very vivid irides- 

 cence ; at their base they are purple, in the middle with 

 bright tints of green and gold ; these occasionally extend 

 to their base ; towards their apex is a mixture of purple 

 and golden lustre. The wings of X. latipes are less vividly 

 adorned ; they are equally dark, have a purple or violet 

 iridescence, and are more or less tinged with green towards 

 their apex. The third submarginal cell and third discoidal 

 cell are longer ia X. latipes than in A", tenuiscapa.
