Female Head. —Black, entirely covered with racquet-shaped scales 
purple in colour. On the vertex extending forwards between the eyes is a 
patch of silvery scales and a similar patch on either side low down adjoin¬ 
ing the orbital margin ; behind on the nape are a few upright scales dark 
purple in colour ; orbital and vertical bristles purple-brown. Basal joint of 
antenna black, with small light brown spatulate scales on the inner surface, 
second joint yellowish-brown at the base with small scales some of which 
are dark brown others golden-brown ; apical half purple, remaining joints 
purple-black with numerous pale downy hairs and purple verticils. Clypeus 
purple, nude. Palpi about one-fourth the length of the proboscis, apparently 
three-jointed, clad with purple-brown scales. Proboscis about two-thirds 
the length of abdomen clad with purple-brown scales. 
Thorax .—Prothoracic lobes large hollowed anteriorly to allow room for 
the head the back of which rests against the prothorax; the external face is 
clad with large flat silvery scales while the surface next to the shoulder is 
clad with metallic-purple scales. Mesonotum black, densely clad with 
metallic flat scales which are spindle-shaped and spatulate the predominant 
colour of which is dark bronze-green or purple. There is no band of silvery 
scales on the shoulder behind the prothoracic lobe as in WyeomyiaMetallicus. 
Scutellum entirely covered with large purple and bronzy spatulate scales, 
some of w’hich have notched ends ; the bristles are purple. Pleurae dark 
purple with numerous flat racquet-shaped silvery scales. Wings brown 
with dark scales large broad and oblique ended. Fork cells very long, the 
first longer but no narrower than the second; its base nearer wing base, its 
stem about three-fourths the length of the cell; posterior cross vein about 
one and half times its own length from the median. Coxae light yellowish- 
brown with flat silvery scales. The whole of the basal third and the venter 
of the remainder of hind femora clad with creamy (or pale golden in some 
lights) scales, the remainder of the hind legs and the whole of the other legs 
clad with metallic-purple or rose-purple scales ; ungues equal and simple. 
Abdomen .—With metallic-purple scales and silvery lateral spots which 
are very large on the apical segments. In the dry specimens the abdominal 
pleurae contract and cause the tergite to bend down on either side the 
lateral spots thus approach each other which gives a false appearance of 
ventral banding: this is seen in nearly all dried specimens. 
Abdomen very slender, with greatly enlarged terminal segments. 
Antennae pilose ; ungues equal and simple. Ornamentation resembles that 
of the female. 
Occurrence .—Described from a series of females and one male taken at 
“ The Gap,” Selangor. 
Remarks .—This species resembles Dendromyia Aureochaetae but is 
easily distinguished by the following differences ; the white scales on the 
prothoracic lobes the absence of the pale brown shoulder patches, the 
colour of the chaetae on the metanotum and the greater breadth of the 
wing scales. 
Dendromyia Aureoch;eta. 
Thorax black with a brownish tinge clad with large scales which are 
metallic and shew bronze and purple tints. Head purple scaled with a
