360 PERCY SLADEN TRUST EXPEDITION 
¢ The frons is somewhat wider and has a few more, but rather smaller, scattered 
bristles ; the lunular area has dark orange pubescence. 
Abdomen. Concolorous with thorax, covered with fine bristles except on basal 
part of second segment, and about the basal third of the next two which are smooth. 
The legs are altogether stouter than in the male, the bristles less conspicuous, and the 
first tarsal joint of hind legs is swollen. 
Note. It is just possible that this is the ¢ of another species, though the two 
occurred in the same locality.

the world.

57. Milichiella tristis, n. sp. (Fig. 41 and Plate 21, fig. 53). 
This species has no silvery sheen in the male, but is in both sexes entirely slightly 
shining brown-black, none of the abdominal segments being in any way shining or even 
brassy. 
Head, black. Top view :—dull black, the ocellar area and upper eye-margins rather 
shining, narrow lower ones pollinated. On these lower ones are two inwardly bent f. o. 
with 5 or 6 smaller bristles; two upper f. o., the first outwardly bent, the other back- 
ward, a small bristle between, another behind. Conv. i. v., div. o. v. on the shining 
triangular ends of upper eye-margins. Two nearly parallel backward bent p. v. inserted 
just behind hind ocelli. Stout oc. inserted between the ocelli: tiny bristles on ocellar 
area, and a small div. pair just on vertex between ocelli. From front of ocellar triangle 
to near the frons are two rows of about 4 pairs of converging bristles, and there are 
scattered bristles just over the forehead. Front view :—antennz separated at base by 
projection of shining lunule. Two long oval black foveze with moderate separating ridge. 
Mouth edge arched, upper lip but little projecting and orange in tone. Side view 
(Plate 21, fig. 53) :—in this aspect the frons is seen to be greyish in colour. Antenne 
black with one stout spine and smaller bristles on 2nd joint: 3rd orbicular with black 
arista suddenly thinning to flagellum which is slightly though evidently pubescent. 
Vibrissee 4 or 5 each side, the first much the longest; a following row of small mouth 
marginal bristles. Palpi stout, black and bristly. Tongue orange at the tip. The eye 
nick is subtriangular with apex nearer top than bottom. 
In the female the shining parts of frons are more evident, and the small bristles 
rather smaller than in the male.
