which laterally become very broad and blunt ended, and which in a cr 00 
hght appear of a brilliant metallic-green to the naked eye in a fresh specime 
while under a lens the colour varies from peacock-blue to bronze-purpl 
and metallic-green the colour appearing intermixed, now one colou 
predominating, now another, as the fly is shifted to different positions. O: 
t le anterior margin are some golden scales and numerous golden bristle* 
and laterally in front, immediately behind the prothoracic lobes there is 
band ot metallic rose-purple scales and beneath this is a triangular patch c 
creamy-yellow scales : the two patches meet on a straight line but thei 
external edges are convex hence with the prothoracic lobe they form a rou^i 
ellipse, composed of the three colours. The scutellum is clad with rathe 
long spatulate scales which are coppery, bronzy or purple-bronze as th 
direction of the hght varies. There is a tuft of bristles over the root of eacl 
wing. _ Scutellar bristles are brown in colour. Pleune are of a darl 
glistening chestnut-brown, naked in parts, scaled in other parts witl 
creamy-yellow or honey-yellow scales. The wings are quite typical 
I he costa and first longitudinal are scaled with metallic rose-purple 
scales. Coxae and femora light yellow, tibia and tarsi much darker 
e coxae, bases and under surface of femora clad with metallic 
golden scales, the upper and lateral surfaces of femora and the whole 
tibia_ and tarsus of fore leg covered with brilliant metallic scale* 
varying from coppery-bronze to rose-purple or bronze-purple, cream? 
scales at the apices of all the femora ; mid leg as the fore except for a band 
of golden scales at the base of the metatarsus and golden scales covering 
rue penultimate tarsal joint; tibia and tarsus of hind leg same as fore 
Ungues equal and simple. Metanotum black. 
Abdomen. First segment scaled honey-yellow laterally, rose-purple 
centrally the other segments brilliant rose-purple with creamy-yellow or 
honey-yellow banding, expanding laterally into triangular patches; venter 
sea ed with metallic-golden scales except segment four which has a patch of 
dark purple scales. 
Male Head. Black with a deep furrow in the centre. There is a 
arge central patch of flat scales of a bronze-green or golden-green 
co our while the _ scales along the orbital margin are peacock-blue, 
and laterally there is a patch of scales peacock-blue or rose-purple according 
to the light m which they are seen. Basal joint of antenna black and nude • 
remaining joints, creamy, growing darker towards the apex, second joint 
scaled with spatulate and elongated scales of a dark brown colour, few 
shewing metallic colouring. There are numerous dark brown hairs on the 
joint ; verticillate hairs, dark brown, almost black, neither very dense nor 
very long._ The antennae are not nearly so marked a feature as they are in 
f, i 1 er0myia ;’ . Pal Pb three-jointed, the first joint shews a slight swelling at 
e base and there is a thinning of the chitin which looks like a joint, but is 
not, there is also a second thinning more basally and the chitin is folded in: 
the whole joint isvory long, the second joint is about half the length of first, 
the third is long and pointed almost as long as first; first joint is almost 
en ire y go den scaled, except on its upper surface near its base where there 
is a patch of rose-purple scales and a band of the same about its middle and 
a few dark scales at the apex dorsally, second joint is golden scaled beneath 
and laterally except apically, and purple scaled above; the third joint is 
entirely purple scaled. Proboscis scaled with purple scales to the angle
