IQI5.] E. BRuNETTI: Notes on Oriental Syrphidae. 241 
Abdomen.—Shining black, with almost microscopic greyish 
pubescence except towards the sides where it is quite distinct. 
The 2nd segment with two oval yellowish, diagonally placed good 
sized spots. The 3rd and 4th segments each with two narrow 
greyish, barely curved lunules, diagonally placed, beginning in the 
middle of the segment, well separated from one another, and 
lying towards the posterior corners of the segments. Belly 
yellowish with a median black stripe. 
Legs.—Coxae and anterior femora black, the latter narrowly 
but very distinctly brownish yellow at tip; anterior tibiae mainly 
brownish yellow with a more or less distinct wide blackish band 
beyond the middle; anterior tarsi brownish yellow with whitish 
reflections. Hind femora much larger than anterior pairs but not 
incrassated, with a row of about twelve small spines on apical 
half of underside; and a second row towards the outerside of a 
less number; hind tibiae mainly black, narrowly brownish yellow 
at base and tip; hind tarsi brownish yellow with whitish reflec- 
tions, basal half of upper and underside of hind metatarsi black. 
Anterior femora with grey hair below; anterior tibiae with similar 
hair but more extensive; hind femora and tibiae covered with 
moderately short greyish hairs; all tarsi moderately grey pubes- 
cent. 
Wings.—Very pale grey; stigma yellowish brown, a very 
slight suffusion over upper part of the upturned section of the 4th 
longitudinal vein; there is also the suspicion of an appendix in 
the middle of the outer side of the anterior cross vein. Halteres 
very pale lemon yellow. 
Described from a single perfect 2 from Sibu, Sarawak, 2-vii-10 
[Beebe], in the Indian Museum. 
Eumerus flavipes, mihi, sp. nov. 
2 Borneo. Long. 5 mm. 
A single example, taken by Mr. Beebe Io miles south of 
Kuching, Sarawak, 24-vi-10, appears to be a closely allied species 
to the above. The principal difference is in the anterior legs 
which are all wholly bright orange yellow. ‘The other differences 
are as follows: the 2nd pair of abdominal spots are yellow, not 
white; the 3rd antennal joint is wholly bright yellow, without 
trace of darkening on the upper edge; the greyish stripes on the 
thorax are absent; the wing tips are distinctly, though not deeply 
darkened as far inwards as to encroach on the Ist posterior cell, 
and there is no sign of an appendix to the anterior cross-vein.

Head.—In @ eyes quite bare, touching for a short distance 
only, the front facets a little larger than the others. Frons 
shining black with greyish dust except for a space bearing the
