scales, chiefly the former, which almost completely cover the 
wings ; veins pale ; cilia brownish-grey ; purpureous and azure 
reflections. Auxiliary vein joining the costa almost opposite but 
somewhat before the base of the first sub-marginal cell ; sub-costal 
cross-vein situated not far before the origin of the second lon- 
gitudinal vein ; middle cross- vein same length as the posterior 
cross-vein, situated considerably beyond the lattei', and about 
opposite the middle of the posterior branch of the fifth longitu- 
dinal vein ; anterior branch of the fifth longitudinal vein issuing 
at a point somewhat nearer opposite to the oi'igin of the second 
longitudinal than to the tip of the sixth longitudinal ; the latter 
situated opposite the posterior cross-vein ; second posterior cell 
about same width as, but scarcely shorter than, the first sub- 
marginal cell, its base lying befoi’e that of the latter.
