half the length of the cell; posterior cross-vein distant about 
twice its own length from the mid cross-vein; supernumerary 
and mid not quite united; sub costal joins the costal about the 
base of the first sub-marginal cell; fringe brown. 
Halteres with grey stem and fuscous knob. 
Length .—5 mm. 
Habitat. —Hong Kong. 
Time of capture. —October. 
Observations. —Described from a single $ in Dr. Rees’ collec¬ 
tion from Hong Kong. It bears some resemblance to both 
G. pipiens and C. J Reesii, the latter from the same locality. 
The thoracic ornamentation should at once separate it, however, 
and the head is peculiarly marked, the occiput being dusky, 
a broad pale grey band surrounding the head in front. The 
legs are rather long and thin, more so than in either of the two 
other mentioned species.
