8. Lepturges venustus, n. sp. 



L. subelongatus, griseus : thorace supra nigro trivittato : elytris 

 maciilis vittisque nigris. Long. 2|-3| lin. S $ • 

 Head greyish. Antennae black. Thorax grey or light brown, 

 the upper surface having three broad and regular black stripes, 

 and the sides each having a similar stripe above the insertion of 

 the coxse; the lateral spines placed close to the hind angles, 

 short, obtuse. Elytra oblong, rounded, and somewhat widened 

 behind the middle in the ? , shorter and more tapering in the cJ, 

 broadly sinuate-truncate at the apex, outer angle of the trunca- 

 ture produced into a tooth in the $ , both angles produced and 

 acute in the d ; upper surface with punctures scarcely apparent 

 through the tomentum, grey or light brown, with a black vitta 

 over the suture, dilated about the middle and narrowed towards 

 the apex, a similar vitta, of more equal breadth, on each side, 

 beginning at the shoulder, detached from the margin of the 

 elytron at one-third its length, and ending in a curve before the 

 apex, and two elongate black spots in the middle of each elytron 

 — one near the base and one behind the middle. Body beneath 

 and legs blackish, with grey pile. 



Ega and Para, on dried twigs and branches. The lateral 

 vitta of the elytra is sometimes interrupted near its termination, 

 leaving a detached spot on the disk near the apex. 



9. Lepturges dilectus, n. sp. 



L. oblongus, depressus : thoracis spinis lateralibus magnis, acutis, 

 subporrectis : elytris profunda sinuato-truncatis, fuscis, plaga 

 communi irregulari ante medium maculisque posticis griseis. 

 Long. 3^ lin. S • 



Head brown. Thorax brown, with grey pile, punctured on 

 the disk and hind margin ; lateral spines placed near to the 

 hind angles, large, prominent, and acute, standing out somewhat 

 from the sides of the thorax. Elytra deeply sinuate-truncate, 

 both angles of the truncature produced and acute, the outer 

 ones most so ; surface closely punctured, brown, with a large 

 common grey patch about the middle, which emits short lines 

 towards the base and apex ; at the base, on each side the scutel- 

 lum, there is a small round grey spot, and behind the large grey 

 patch there are, on each elytron, two short grey lines, followed 

 by a transverse grey streak connected with the suture near the 

 apex. Body beneath and legs reddish, with grey pile. 



Ega, on dead branches. There is a Cayenne species* resem-
