Wyeomyia Metallica. n. sp. 
Thorax light brown, clad with spatulate and spindle-shaped scales 
metallic-violet-blue. Prothoracic lobes white scaled. Head with dark 
metallic-purple spatulate scales. Abdomen metallic-purple with silvery 
lateral spots. A tuft of about sixteen hairs on the metanotum arranged in 
two superimposed transverse rows. 
Female Head .—Entirely covered with large broad spatulate scales rich 
metallic-purple or blue in colour; on the vertex is a very small patch of 
silvery scales and a few low down laterally border the orbital margin on 
either side. The extreme back of the head is concealed by the collar like 
prothorax and it cannot be determined whether there are any upright scales 
or not; orbital and vertical bristles dark-brown. Basal joint of antenna 
black, naked; second joint black, with pale yellow scales on its inner face, 
remaining joints black with white downy hairs and almost black verticils. 
Clypeus black and nude. Palpi about one-seventh the length of the 
proboscis, clad with dark brown scales, purple in certain lights. Proboscis 
with similar scales. 
Thorax .—Prothoracic lobes very large, meeting above and forming 
quite a conspicuous collar behind the head, completely covered with large 
racquet-shaped scales which are silvery in front, a few behind being dark 
brown but shewing interruption colours as the direction of the light \aries. 
Mesonotum brown, densely clad with spindle-shaped and large spatulate 
scales. These scales are metallic the predominant colour is dark peacock- 
blue or violet. When seen alive this violet-metallic thorax is quite a 
conspicuous feature. The scales are very large and those in the centre are 
chiefly spindle-shaped while those over the wing bases and in front of the 
scutellum are spatulate. The scutellum is light brown and entirely covered 
with spatulate scales which are much smaller than those on the mesonotum, 
the scales on the central lobe get progressively smaller from base to apex, 
the apical rows being as broad as long and racquet-shaped with rather 
square ends. In colour these scales resemble those on the mesothorax; 
scutellar bristles dark brown : four to the central lobe. Pleurae brown with 
a purple hue clad with patches of pearly-white scales some rounded and 
almost circular others longer and spatulate. \\ ings brown, with a purple 
hue, clad with dark purple-brown scales; median scales small, double on 
all veins to the fifth (excl.); lateral scales narrow with parallel edges and 
rounded ends; first fork cell longer and rather broader than second, its 
base nearer wing base; posterior cross vein twice its own length from 
median. Coxse light muddy-yellow; fore coxae with rather long silvery 
scales down the front, mid and hind coxae with broader scales, remainder 
of all legs clad with metallic-purple-bronze scales; ungues equal and simple. 
Metanotum brown, with a tuft of dark brown and golden-biown bristles 
near its junction with the abdomen. These bristles are arranged in two 
lines and there are about eight in each line. Abdomen with metallic- 
purple scales and large triangular basal silvery lateral spots. \ enter 
cannot be seen. 
Occurrence .—Described from a single female taken in the bungalow at 
Bukit Kutu.
