“ An erroneous opinion has prevailed pretty generally among naturalists respecting 
the colour of this insect, which when living they conceived to be similar to that of a 
dried or withered leaf. This, it may be observed, is commonly the appearance of the 
insect after death : such was no doubt the colour of the specimens delineated by Roesel; 
nor can we for a moment hesitate in believing that the insects described by the accu- 
rate Linnaeus and Dr. Shaw exhibited the like appearance. The specimen of the 
winged insect in our cabinet, has been preserved, however, with more than usual care. 
Immediately after the death of the creature, as we have reason to suspect, the abdomen 
had been opened, and so nicely excavated that no portion of the entrails, or oily fluids, 
which would have inevitably destroyed the true colour, was allowed to remain. The 
natural colour is therefore preserved, which is not of a pale brown, as is commonly 
imagined, but of a delicate, lovely green ; a colour dependant, it appears, upon a thin 
internal coating immediately beneath the outer skin, the latter of which is perfectly 
transparent, and destitute of any colour. 
“ The pupa of this curious species is represented, together with the perfect insect, 
on the Yinca rosea. 
“ There is also a much smaller pupa depicted in the upper part of the plate, that 
was discovered in one of the islands of the Indian seas, and belonged to the celebrated
