Remarks. This mosquito is quite unique as far as my experience goes 
and cannot be mistaken for any other species. The extraordinary length 
and slenderness of the abdomen separates it from all the other species of 
this genus. It is possible it is the male of T. Rubithorax but at present I 
prefer to treat it as separate species of which I have no female. It is very 
difficult to see on the wing. Several species of tipulida; closely resemble it 
on the wing. 
Genus 14.— Hsemagogus —Theobald. 
Unrepresented in Malaya. 
Genus 15.— Skeiromyia. — nov. gen. 
Proboscis very long. Antennae plumose in the male pilose in the 
female. Clypeus heavily scaled. Head clad with large broad spatulate 
scales. Prothoracic lobes densely scaled with quadrilateral scales. 
Mesonotum densely clad with spindle-shaped and clavate scales. 
Scutellum with spatulate scales. Wings with long fork cells and linear 
lateral scales. 
. Fern arks. One species of this genus is at present known though it 
varies somewhat in colour in different localities. In some lights the colours 
are metallic generally in very soft shades of bronze and purple. The 
scaling of the thorax is quite unique and together with the scaled clypeus 
form good generic characters. 1 he larva closely resembles that of 
Coionemyia both having a peculiar chitinous process on the thorax. 
Skeiromyia Fusca. n. sp. 
Head clad with large dark bronze spatulate scales and a narrow 
margin of bluish-grey scales along the eyes. 1 horax clad with spindle- 
shaped and spatulate scales bronze under a hand lens fawn-brown under a 
2/3. Proboscis longer than the abdomen. Abdomen and legs with dark 
brown scales, venter pale. 
Female Head. W ith a very narrow bluish-grey margin to the eyes, 
the rest of the head clad with large dark-bronze spatulate scales and a few 
dark brown narrow curved ones behind. Basal joint of antenna light 
yellowish-brown, clad with pale, small scales on the inner face, second joint 
with scales, remaining joints light brown with brown verticillate hairs. 
Clypeus light brown thickly chid with rather long white scales with 
rounded ends. Palpi slender, about one-sixth the length of the proboscis and 
apparently one-jointed, even when denuded. Proboscis very long, longer 
than the abdomen. Palpi and proboscis clad with scales which appear 
olive-brown or coppery-bronze with different lights. 
Thorax. Prothoracic lobes brown, clad with small racquet-shaped 
scales silvery-brown in colour. Mesonotum dark purple-brown clad with 
fusiform and large spatulate scales over the roots of the wings and at the 
base of scutellum which are of a light bronze under a hand lens, while 
under a 2/3 the colour varies, but is always some shade of brown 
either. olive or fawn or bronze-brown ; on the shoulder above the pro¬ 
thoracic lobe, is a large patch of bluish-grey fiat scales best seen in the male.
