blackish, with some long black hairs. Eyes with rather thick 
short yellowish grey pubescence, which when viewed from certain 
directions appears quite white. Frons as in hirticincta, the dust 
on the eye margins less distinct. Face with the centrai knob 
somewhat large, conspicuous and rounded; aeneous black, shining, 
with very sparse and short, almost microscopic greyish pubescence, 
the central knob and the space immediately below it very 
shining black. Mouth border narrowly orange, moderately pro- 
duced, with a small bump on each side of it. Eye margins dull 
blackish, with sparse rather short greyish hairs. Occiput grey with 
short greyish hairs. Antennae dul! dirty brownish grey, arista 
bare, black. 
In the @ the frons not much narrowed on «vertex, and about 
one-third the width of the head just above the antennae is shining 
black with a little grey pubescence. 
Thorax and scutellum shining black, with rather thick 
brownish yellow pubescence, a few black bristly hairs intermixed 
in front of wings, and on hind margin of scutellum, where these 
black hairs are much longer than the general pubescence. Sides 
moderately dark shining greyish, with yellowish grey hair. 
Abdomen all shining black, with close, pale yellowish grey 
pubescence; belly similar. 
Legs blackish, with pale yellowish grey pubescence. Extreme 
tips of femora, base of tibiae rather narrowly in @# and to the

Q Simla. Long. 8 mm. 
Head.—Frons and face shining aeneous black, almost with a 
deep indigo tinge, the frons widening gradually from vertex to 
about one-third the width of the head above the antennae. Frons 
slightly prominent above the antennae from eye to eye, giving 
the appearance of an elongate transverse callus. Above this callus- 
like prominence is an oval, yellowish grey dust spot each side 
touching the eye margins. Frons, except the dust spots, wholly 
covered with thick black hairs. Face shining black, the central 
knob large and prominent, the mouth border but slightly produced, 
very narrowly orange; a little almost microscopic pubescence at 
the sides of the mouth but not extending just below the eyes. 
Eye margins distinct, grey, widened immediately below antennal 
prominence, and on this wider part on each side of the face 
are three elongate notches as though impressed with a knife.
