clad with metallic golden scales ; the upper and lateral surfaces 

 of the femora and the whole tibia and tarsals of fore leg covered 

 with brilliant metallic scales, varying from coppery-bronze to 

 rose-purple or bronze-purple; there are creamy scales at the 

 apices of all the femora ; mid legs as the fore, except for a band 

 of golden scales covering the penultimate tarsal segment ; tibia 

 and tarsals of hind legs the same as the fore. Ungues equal and 

 simple. Metanotum black. Halteres with pale yellow stems 

 and dark scaled knobs. 



Abdomen with the first segment scaled creamy-yellow laterally, 

 rose-purple centrally ; the other segments brilliant rose-purple, 

 with creamy-yellow banding expanding laterally into triangular 

 patches ; venter scaled with metallic golden scales, except segment 

 four, which has a patch of dark purple scales. 



Length. — 10 mm. 



$ . Head black, with a deep furrow in the centre ; there is 

 a large central patch of flat scales of a bronze-green or golden- 

 green colour ; the scales along the orbital margins are peacock- 

 blue, laterally there is a patch of scales peacock-blue or rose- 

 purple according to the light in which they are seen. 



Antennae with basal segment black, nude ; remaining 

 segments creamy growing darker towards the apex ; the second 

 segment scaled with spatulate and elongated scales of a dark 

 brown colour ; a few scales show metallic colouring. There are 

 numerous dark brown hairs on the segments ; the verticillate 

 hairs dark brown, almost black, neither very dense nor very long. 



Palpi three-jointed ; first segment shows a slight swelling at 

 the base, and there is a thinning of the chitin which looks like a 

 joint but is not ; there is also a second thinning, and the chitin 

 is folded in more basally ; the whole segment is very long. The 

 second segment is about half the length of the first ; the third is 

 long and pointed, almost as long as the first segment, which is 

 almost entirely golden-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 dorsally at the 

 apex ; the second segment golden-scaled beneath and also the 

 sides, except apically ; the upper surface is purple-scaled ; the 

 third segment is entirely purple-scaled. 



Proboscis scaled with purple scales to the angle, then green- 

 scaled. The markings of both proboscis and palpi vary. (In one 

 specimen the first segment of the palpus is entirely gold-scaled 

 except for a ring of purple scales on the middle and apex.)
