gold or copper: others are ornamented with a tinge 
of golden green, which far exceeds the appearance 
of all artificial painting or varnifh. The prefent 
fpecies, though lefs rich in colour than feveral others, 
is the largeft of the whole genus; and as its larva has 
been obferved and well figured by Madam Merian, I 
have thought it not improper, as an elucida¬ 
tion of the genus, to add the larva as repre- 
fented by that lady, to the figure of the compleat 
infedl. This larva grows to the fize reprefented, 
and refides near the roots of plants : when fully 
grown, it lies dormant for fome time in a fmall 
cavity beneath the furface of the ground, and, cart¬ 
ing its exterior fkin, becomes a pupa or chryfalis, 
out of which, after a certain fpace, proceeds the 
perfedt infedt. Its general colour is that of highly- 
polifhed copper; the edges of the thorax and wing- 
cafes tinged more or lefs with green. The wing- 
cafes are of a roughifh or wrinkled furface, and 
flightly ribbed longitudinally. It is to be alfo ob¬ 
ferved that the antenna;, which in moft of the genus 
are fimply fetaceous, are in the prefent fpecies of a 
fomewhat lamellated or pedtinated appearance. This 
beautiful infect is a native of South America.
