92 ERASMIA PULCHELLA. 
oblong, suboval, entire, the hinder nerve a little 
curved, the discoidal cell closed; posterior wings 
subrotund, the hinder nerves curved ; body slender, 
subcylindric ; head and palpi small ; tongue long 
and spiral ; legs slender. 
The only species hitherto described measures 
about three inches two lines between the tips of 
the wings : prevailing colour silvery green ; ante- 
rior wings black, ornamented with green-blue sil- 
very spots, an irregular red bar before the middle, 
and large white spots behind the middle ; posterior 
wings straw-coloured, black at the base and apex, 
the nervures green-blue. 
" The above insect," says Mr. Hope, " is one of 
tlie most lovely in colouring of all the Lepidoptera. 
When viewed by individuals standing in different 
lights, the blue appears to one person to be a vivid 
green, to another of a lazulite blue. I have had 
drawings made by different persons ; the first con- 
tends that the colour is green, the second that it is 
blue ; in short, both are right ; all depends on the 
situation in which the individual views the speci- 
mens." 
This insect is likewise from Assam.
