Abdomen .—Clad with metallic-purple scales. On the venter there are 
basal silvery bands and laterally there are large triangular basal spots 
creamy with a silvery lustre. Male unknown. 
Occurrence .—Described from a series of females taken in the day time in 
jungle near Kuala Lumpur, in April and May. 
Remarks .—It is a very distinct species and the broad asymmetrical 
wing scales and the short proboscis with metanotal chaetae shew it to 
belong to this genus. There are other distinctions between it and 
Wyeomyia at least the Wyeomyias of this peninsular such as the presence 
of scales on the basal joint of antennae the greater size of the mesothoracic 
scales. 
Dendromyia Ach^tze. n. sp. 
Thorax blackish-brown, clothed thickly with metallic spatulate and 
spindle-shaped scales purple or bronze-green. Head with dark purple 
scales in the centre and silvery ones at the sides and on the vertex. Pro- 
thoracic lobes and pleurae with silvery scales. Abdomen purple-bronze 
above with pearly-white basal bands on the fifth, sixth, and seventh 
segments and lateral spots to all segments. Chaetae apparently absent from 
metanotum. 
Female Head. —Black, clad with flat scales which are for the most part 
racquet-shaped. There is a small patch of silvery scales on the vertex 
and fairly large lateral patches of silvery scales with a bluish tinge; the 
rest of the head is clad with dark purple-bronze scales, and behind with a 
few broad-topped upright scales with the free edge serrated, black or dark 
purple in colour; they are seen with some difficulty as they lie very far 
back; vertical and orbital bristle black. Basal joint of antenna black with 
a purple tinge with a few small scales on its inner face, second joint brown 
at the base, purple at the apex, a tuft of brown scales on its inner face, 
remaining joints dark purple with silvery downy hairs and black verticils. 
Palpi about one-sixth the length of the proboscis clad with purple-bronze 
scales. Proboscis rather long, almost as long as the abdomen, apex 
fusiform ; scaling similar to palpi. 
Thorax .—Prothoracic lobes entirely covered with brilliant silvery scales 
racquet-shaped, rather longer than broad ; the lobes are very large but do 
not quite meet above. Mesonotum purple-black (in some lights there is a 
brownish tinge) entirely covered with large flat scales fusiform and 
spatulate; in front numerous scales project forwards overhanging the 
prothorax abo ve; the dorsum of the mesothorax is somewhat denuded but 
there is no sign at either end of any ornamentation ; there are numerous 
purple-brown bristles overhanging the wing bases. Scutellum light 
yellowish-brown with large purple-brown spatulate scales on the lateral 
lobes and at the base of the central lobe, the apical two-thirds of the latter 
clad with racquet-shaped silvery scales. There are six bristles to the 
central lobe which are knocked off in the specimen but the pits for their 
insertion are perfectly plain. Pleurae pale brown at the insertion of the 
wings elsewhere dark purple-brown densely clad with brilliant silvery 
racquet-shaped scales. Wings smoky, heavily clad with dark brown 
scales metallic-purple where they are massed as on the costa; the median
