The three forms described in this paper are very much 
alike in the form of fore tarsi, color of wings and form of 
the long outer hypopygial appendages. Metallicus has the 
abdomen wholly metallic above, tips of hind femora con- 
spicuously black above at tip and third antennal joint a 
little larger; flavicoxa differs from both the others in hav- 
ing the tibiae and femora wholly yellow, and the posterior 
margin of pleurae yellow, it differs from varicoxa in having 
all coxae yellow, middle tibiae wholly yellow. They all differ 
from each other in the form of the palpi, bristles on pos- 
terior surface of hypopygium and the inner hypopygial 
appendages.
