the sixth and seventh segments with narrow apical yellow 
bands, no basal pale band or mark to the last; laterally are 
median white spots; venter ochraceous. Legs with coxae

beneath ; tibiae deep brown, paler ventrally ; metatarsi and

basal bands, last two deep brown, unbanded ; in the hind legs

second posterior cell broad where it joins the border of the wing, 
its stem longer than the cell; posterior cross-vein rather small, 
nearly twice its own length distant from the mid-cross vein ; 
halteres with a pale stem and fuscous knob. 
Length.—4 to 4°5 mm. 
Habitat.—¥ yi (Dr. Hall). 
Time of appearance.—April, May and June. 
Observations.— Described from several ?’s taken by Dr. Hall 
at Ba in Fiji. It is found in houses and is active at night. 
The abdominal ornamentation is very characteristic ; the species 
cannot well be mistaken for any other. The proboscis is really 
very broadly pale banded.
