which is not united with the others : there is a 
small spot of black in the yellow margin before the 
middle. The scutellum is black, with an oblong 
patch of yellow. The elytra are deep chestnut-red, 
approaching to black at the apex, with two curved 
lines of yellow down the middle of each, which are 
attenuated behind, and generally united to a cross 
stripe of the same colour, from the suture : there is 
also a stripe of yellow' round the hinder margin of 
each w ing-case, which terminates before the middle, 
where it is dilated into a triangular spot with the 
apex directed inwards. The under side is black, 
curiously variegated with yellow. The legs are 
chestnut-red, the hinder thighs striped with yellow. 
GYMNETIS NERVOSA. 
PLATE XVII. Fig. 5. 
This genus is easily distinguished from Cetonia, 
by having the thorax produced in the middle behind 
into an angle which occupies the place of the scu- 
tellum. About fifty different kinds are known, by 
far the greater part of which belong to tropical 
America. The species named nervosa is entirely of 
a reddish-brown colour, having the upper surface 
variegated with linear and angular patches of black. 
The under side and legs are black.
