(exci; ) 
green, the wing scales are deeply ribbed, and instead of 
being roughly flat are curved; when examined under 
transmitted light the colour becomes a delicate 
pinkish heliotrope. 
Arhopala eumolphus is also lustrous metallic green but 
inclining to bluish-green ; the scales are deeply ribbed 
and curved; under transmitted light they become 
pinkish mauve, different in hue from R. duma. 
Heliophorus brahma is fiery metallic reddish golden colour, 
and becomes under transmitted light uniformly 
green, with no tinge of yellow but rather of the 
bluish hue if anything. 
Callophrys rubi, with the well-known green colour of its 
underside, is quite different from the metallic greens 
obtaining in the exotic species. To the naked eye 
the colour looks uniform but the scales are really 
brilliantly mottled, the mottling under a good direct 
white light being very conspicuous and very brilliant. 
Under transmitted light the scale is found to be 
packed with reddish globules which lie in the sack 
quite regardless of the ribbing; they are very 
irregular in size and shape, and whilst not entirely 
confined to the apical portion are much less plentiful 
proximally, with the result that that portion is pale 
greyish, but rapidly becomes reddish distally. 
Pithecops dionysius is very white on its underside, but under 
transmitted light there is a faint brownish reflection ; 
with the upper ribbed wall removed it is densely 
but finely granulated with granules of a greyish 
tinge. 
Larinopoda lagyra is quite white to the naked eye and 
remains rather transparent whitish with transmitted 
hight. When the ribbed upper wall had been re- 
moved the scale was not found to be empty but was 
heavily granulated with grey; the granules however 
were quite invisible as an opaque object. 
Larinopoda soyauxi is slightly creamy white but becomes 
yellowish under transmitted light; the upper chitine 
being removed discloses a coarsely granulated surface,
