Genus i.— Megarhinus. — Robinean-Desvoidy. 
Note. —This genus is unrepresented in Malaya. 
Genus 2.—Teromyia. —xov. gen. 
Head with large broad spatulate scales and a few upright scales 
ehind. Proboscis very long and curved. Palpi five-jointed (the two last 
)ints are very small), about one-third the length of the proboscis. W ings 
/ith an extra cross vein near the base joining the sub-costa and first 
)ng vein and with very short fork cells, the first much smaller than the 
3 Cond ; median cross-vein considerably nearer the base of the wing than the 
upernumerary, posterior cross-vein sometimes placed to the apical side 
fthe median. Lateral tufts of erect hairs generally present on the last 
no abdominal segments. Colouring metallic. 
Remarks .—In Theobald’s monograph it is stated that in members of 
• his genus there are no upright scales on the head. There are always 
pright scales on the nape, but in a dried specimen these may be concealed 
y the thorax if the head is drawn up against it by retraction of the neck, 
mother point that appears to have escaped notice is the presence of an 
xtra cross-vein which is present in all my species ; it runs from about the 
fiddle of the sub-costa to the first long vein ; there is also a false vein 
nscaled running between the fifth and sixth. This is a real vein and not 
mere fold in the wing. Five species are here described, and they are all 
pparently new species, though it may be T. Quasiferox may prove to be 
nerely a variety of M. Ferox or Immisericor.

The following description is from a fresh specimen. The colours were 
ir more brilliant then than in the dry specimen. Mesonotum dark bronze- 
reen, almost black to the naked eye with margin scaled pale golden and 
pple-green, in some lights azure-blue, shoulders silvery. Prothoracic lobes 
fith silvery, azure-blue, and apple-green scales. Scutellum apple-green. 
Legs rose-purple, with two white bands on the mid legs and one at the base 
f the first tarsal joint on each hind leg. First segment of abdomen deep 
'lue in the centre, golden-yellow at the sides, remaining segments royal- 
'urple on the dorsum with creamy-yellow (silvery in some lights) lateral 
pots. The venter scaled creamy-yellow with a band of purple running down 
he whole length in the centre. 
Female Head. —Black, clad behind the eyes with scales which are blue 
nd green, at one time appearing blue, again with a slight change of posi- 
ion apple-green while the scales behind are dark coppery-purple, but turn 
he head against the light and the scales on the orbital margin become 
>eacock-blue with an edging of rose-red, while the rest of the scales are dark 
li >ronze-green ; there are dark brown upright scales behind ; vertical and 
-rbital bristles dark purple. Basal joint of antenna black, thickly clad 
vith small silvery scales above and to the inner side, and with a downy
