COLEOPTEROUS INSECTS. 221 



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 aP cross 

 stripe of the same colour, from the suture : there is 

 also a stripe of yellow round the hinder margin of 

 each wing-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.
