d with a lurid tinge along the costa, whence a
short oblique blackish streak proceeds by the praebrachial transverse
vein; discal transverse vein clouded with brown, hardly curved, parted
by less than one-third of its length from the border, and by much more
than its length from the praebrachial transverse, which is very oblique;
halteres testaceous, with black tips. _Male._ Head with the fore black
band interrupted; eyes with very long petioles, the latter about
three-fourths of the length of the body; scutellum green; femora tawny
towards the base. _Female._ Eyes with short petioles, extending a little
beyond the sides of the thorax; scutellum blackish purple. Length of the
body 5-6 lines; of the wings 12-13 lines.
