black, the palpi very short, the clypeus showing a dull grey sheen. 
Thorax shiny black clothed with irregularly arranged small bronzy 
spindle-shaped scales and large flat violet, blue and green scales, a line 
of the silvery scales in front of the root of each wing at the side and in 
some lights there appears an apple-green line behind: the large flat 
scales are most dense just behind the root of the wings where they are 
very large and project outwards and also just before the scutellum ; pro- 
thoracic lobes with flat various shaded scales and there are numerous 
short stout bristles projecting forward from the mesonotum, over the 
head ; scutellum testaceous with flat black scales : border-bristles black, 
four large and some small ones on the mid lobe ; metanotum brown

spots, apex swollen and very bristly; claspers very small and delicate, 
pale grey. 
Legs bronzy brown, deep ochreous at their base, the coxæ having 
a patch of silvery scales ; venter of femora paler than remainder of 
the legs. 
Wings (Plate II) with dense brown scales, the first submarginal cell 
longer but very slightly narrower than the second posterior cell, its base 
slightly nearer the base of the wing than that of the second posterior cell, 
its stem about half the length of the cell, stem of the second posterior 
nearly as long as the cell ; posterior cross-vein about the same size as 
the mid cross-vein and about one and a half times its own length 
distant from it ; scales as shown in the figure plate III. Halteres rather 
stout, stem pale, knob fuscous. 
Length : 4 mm. 
Habitat : Singapore (Biró, 1902). 
Observations : Described from a perfect male. It most nearly 
approaches P. iongir ostris Theob., but can at once be told by the shorter 
proboscis and unadorned legs. The male claspers very small and pallid.
