bulk of the wing scales; these are broadish and comparatively 
short, being about twice as long as the width; they are all 
decidedly curved, the highest part of the curve being in the 
centre, they are shovel-shaped, deeply ribbed, with the apices 
cut off quite square. There are no “ blasenschuppen”’ in 
this species, nor in any of these metallic species that I am 
yet acquainted with. Another equally lustrous metallic 
green insect is Arhopala eumolphus, but the green is more 
delicate though quite as refulgent. Here again the costal 
cable is composed of long brown narrow scales with serrated 
apices, whilst the veins are also clothed with brown scales 
of moderate length, rather broad, with very deeply serrated 
apices, leaving exceedingly fine sharp points between; the 
metallic scales are all of one pattern, being a long oval, much 
longer than in R. duma, decidedly broader in the centre, and 
abruptly and evenly truncate at the apex; they are deeply 
ribbed and curved, but the curve is not quite so marked as 
in the previous species. Heliophorus brahma is of a wonderful 
metallic lustrous reddish-golden colour, probably the most 
brilliant insect in the world; it is allied to the genus Heodes, 
though all the other species in the genus are bluish in the 
males. The brown scales in this butterfly call for no special 
comment, but the metallic golden ones are of two sizes; 
those in the cell are long, broad, slightly wider in the centre, 
with the apices very slightly arched, not abruptly cut short 
as in A. eumolphus, those on the fold are shorter and 
broader, tapering somewhat wider to near the apex which 
is moderately rounded off, both are deeply ribbed. In the 
secondaries the metallic scales are shortish and broad, tapering 
more widely to the apex which is scalloped, the ribbing and 
the colour are precisely as in the primaries. There are no 
“blasenschuppen ” in this genus. To return to the genus 
Arhopala in which nearly all the species are blue, perhaps 
one of the most beautiful and brilliant is helius, which is 
brilliantly deep blue in its costal and terminal area, and equally 
brilliantly almost Cambridge blue in the median area and on 
the fold; the scale in each of these cases appears to be of the 
same structure; the pattern is quite similar, a long broadish 
scale, evenly rounded at the apex and rather narrow at the
