the apices of the antepenultimate and preceding joints mauve, 
the latter with silvery white apical scales as well, the last three 
joints nearly equal ; proboscis deep black. 
Mesothorax deep rich brown, with narrow curved paler dull- 
brown scales in the middle, bronzy-brown in some lights ; 
the scales become broader at the sides, where they form a 
blue and mauve line, which at the front of the mesothorax 
becomes white ; beneath the blue line and the silvery pleurae 
the thorax is dark brown; over the roots of the wings are 
numerous long brown bristles and tlat green and metallic scales, 
posterior part with flat green, mauve, and coppery scales, also 
the scutellum ; posterior border-bristles of the scutellum rich 
brown, longer on the lateral lobes than on the median; meta- 
notum deep brown ; pleurae dark brown, with two large confluent 
snowy white patches. 
Abdomen with the basal segment pale green centrally, white 
laterally ; the next two segments bright blue, the following violet 
and purple, the apical one with some brilliant coppery scales and 
the penultimate more brilliant violet than the rest ; there is an 
apical lateral white tuft of hairs on the antepenultimate, a black 
tuft along each side of the penultimate and orange hairs on the 
apical one, forming a distinct caudal tuft, like T. immisericors | 
(Walker) ; there are also white lateral patches most prominent 
on the basal segments. 
Legs damaged, the hind pair alone being perfect; to the 
naked eye they are black, with a prominent white band on the 
base of the first tarsal joint ; under the lens they show metallic 
violet reflections, and the under side of the base of the hind 
metatarsi is also white; hind ungues equal and simple; femora 
and tibiae of fore legs deep brown, with metallic reflections ; 
remainder of the legs absent. 
Wings with testaceous brown veins and slightly tinged with 
brown along the costal borders ; scales brown ; supernumerary 
cross-vein nearly four times its own length nearer the apex of the 
wing than the mid cross-vein ; the mid rather more than its own 
length nearer the apex than the posterior cross-vein ; the latter 
long, sloping towards the base of the wing, about four times the 
length of the mid ; first sub-marginal cell very small, about half 
the length of the second posterior cell ; halteres small, brown. 
Length.—9 mm.
