apically banded ; the tarsi are black without any coloured scales; 
metatarsi of front legs are basally banded ; other tarsal segments 
black • in the mid legs the metatarsi and the first tarsal segments 
are basally banded • in the hind legs the metatarsi are basally 
banded with yellowish scales and apically with white scales • all 
the remaining segments are basally and apically banded with 
white scales. 
Wings spotted. The black spots on the costa extend to the 
auxiliary veins. They are seven in number, and are situated as 
follows :—two small basal ones, the second a little larger than 
the first, the third having a white dot in its middle, the fourth 
and fifth united on the auxiliary vein by black scales, the sixth 
placed obliquely, the seventh near the apex; the other veins are 
irregularly spotted with white scales, the fringe is spotted black 
and white on its basal half. The underside of the body presents 
the following markings :—the pleura densely covered with im¬ 
bricated, flat, whitish scales ; the trochantae, coxae, and the base 
of the femora are covered with white scales ; the ventral segments 
of the abdomen are spotted basally with white scales and apically 
with a well-defined, narrow, white line. 
9 . Proboscis black with a few scattered white scales and a 
white band just below the first anterior third. Palpi longer than 
the half of the proboscis, with a few scattered white scales and 
white bands; the apical segment bears two moderately long 
hairs. The fore part of the occiput is covered with long, narrow- 
curved white scales, the hind portion with yellow upright forked 
scales ; the anterior lateral portions with black, upright forked 
scales. 
Scutellum with a median and two lateral tufts of long black 
hairs and a few long, curved, flat white scales. Thorax and 
pleurae as in the $. Halteres yellowish, with small, white

Habitat. —Yacoas, Mauritius. 
Observations .—The larvae of this species were found by 
Professor Ronald Ross in the holes of trees at Yacoas. No adults 
were seen in houses, although larvae were near houses. It is 
recorded as being very scarce. D’Emmerez de Charmoy referred 
to it as being near Gulex mimeticus, Noe. He figures the wing on 
Plate X. of the “ Annals of Tropical Medicine and Parasitology,” 
vol. ii., No. 3 (1908), and entirely misses out the third long vein 
and all the cross-veins, and the shape of the wing does not at all 
resemble the specimen in the Liverpool University Museum. It
