the abdomen with white hairs, caudal tuft dense, brilliant golden- 
yellow, almost orange. 
Legs most brilliant, golden, and deep clear green and purple ; 
fore legs with the femora and tibiae rich golden-green, pale golden 
beneath the femora ; metatarsus and first tarsal white, second 
tarsal deep green; mid legs much the same but with more 
brilliant golden reflections and the basal part only of the 
metatarsus white beneath (rest missing); hind legs with brilliant 
golden femora and tibiae, deep metallic green at their apices ; 
hind metatarsi golden at the base, then deep green (tarsi missing). 
Wings brownish, with deep golden-brown veins; super¬ 
numerary cross-vein about four times its own length nearer the 
apex of the wing than the mid cross-vein, which is close to the 
long sloping posterior cross-vein. Halteres ochraceous, fuscous 
at the knob. 
Length. —10 ‘5 mm. 
Habitat.— Java, Sumatra, Batavia (Wiedemann, Schiner, 
Van der Wulp) ; Singapore (Wallace). 
Observations. —Described from a specimen so named in Bigot's 
collection. It is one of the most beautiful Megarhina ; I have 
seen ; unfortunately the legs are not perfect. I think there can 
be no doubt as to its identity. All three previous descriptions 
differ in some details, so that the minor differences I detect can 
be of no account when we consider the diverse shades of colours 
exhibited by each specimen of this genus when examined in 
different lights. 
Wiedemann’s original description is based on a d specimen; it is as 
follows : “ Antennae deep fuscous; palpi steely, made up of four nearly 
equal joints, the fifth subulate and destitute of hairs ; head with metallic 
green and golden scales; pleurae whitish, shaggy ; abdomen steely; bases 
of the segments violescent; venter golden on either side ; laterally with 
whitish cilia; anal end with golden cilia; wings slightly yellow, with 
dusky-yellow veins ; halteres yellowish ; feet steely ; bases of the femora 
yellowish and hairy. No white on the tarsi of the lore legs; the fiist and 
second joints of the mid and the second of the hind legs whitish.” Schiner * 
and Van der Wulpf both nole this species, but we cannot judge from 
the descriptions as to the identity. 
The fact that there is white on the fore tarsi in Bigot’s 
specimen need not be taken into account, as the tarsal markings 
are one side only, and can be easily overlooked.
