Fical bia (Mymomyia) metallica Leicester IgoS
FEMALE, after LEICESTER. Head deep purple, clad with broad scales, elongated, spatu-
late wI th concave ends. These scales vary in colour according to the direction of the light
from pale golden to peacock- or azure blue or peacock-green; in a fresh specimen they
may appear deep gold or rose-purple. There are a few black, upright scales on the nape,
f pyramidal in shape, blackish-brown and with a few scales on the inner face. Antennae
unusually long, fs I as long as any two succeeding joints. Remaining joints deep purple
with &ark brown, verticillate hairs. Palpi clad with golden scales at the base and black
at the apex. Proboscis clad with dark purple scales above, golden below. Thorax. A@
blackish brown in some specimens, light brown in others, clad with long bristles only,
Mesonotum deep purple brown in some specimens, in others light brown with deep
purple lines and patches; clad with black narrow, curved scales and bright golden
scales and bristles on either lateral margin. Scutellum deep brown with black narron-
curT7ed scales. Pleura bright ochraceous or light yellowish brown. M’ings with dark
purple scales; fork cells very short, of about equal length, nf narrower than pf, its base
nearer the wing apex, its stem nearly twice as long as the cell. Coxae and bases of femora
ochraceous; front and mid-femora ochraceous at the base and beneath; purple above;
tibiae clad with purple scales, the hind tibiae with a broad pale golden band at the apex;
k--t3 on front and mid-legs purple scaled with a narrow, apical band of pale golden
scales on each; h--t4 of hind legs with narrow golden band, last joint entirely clad
with golden scales, much brighter in the fresh specimen than in the dry, Abdomen-
First segment dark purple in the centre and ochraceous at the sides. A central, longi-
tudinal golden line runs the length of the abdomen from the second segment; the rest
of the dorsum being clad with bright purple scales. The venter is golden, but when dr>-
becomes golden-brown.
MALE. In a typical specimen the antennae are densely plumose, the hairs being
bright flaxen, but in others they appear more of a steel-grey. The proboscis is very long
and clad with golden scales with a black band at the apex. The palpi are as long as
the proboscis and apparently consist of only two joints, the ultimate joint being clavate
with black scales at its apex, golden-brown at its base, the penultimate joint bright
golden with a black band at its base, in its centre and at its apex.
