streak or spot, followed by an ashy club-shaped streak near the 

 suture, which reaches to the apex ; the faint dorsal carinse are 

 speckled with grey and black, and the antennse and feet are 

 spotted with brown and grey. The males are known by the 

 enlarged basal joint of the fore tarsi. It varies much in the 

 markings of the elytra, the subapical black spot and the apical 

 ashy streak being both subject to become either enlarged in size 

 or diminished so as to be scarcely visible. 



The species has a wide range, and the varieties do not appear 

 to be restricted to localities, specimens before me from Panama 

 not differing from others taken on the banks of the Tapajos and 

 the Upper Amazons. It is a common insect on felled trees in 

 new clearings throughout the Amazons region.

Head tawny, vertex with two black spots close to the inner 

 margin of the eyes, Antennse reddish brown, second to fifth 

 joints each with two whitish rings, the remaining joints (except 

 the second) each with one pale ring. Thorax uneven, tawny 

 varied with dusky, and marked with four short and crooked 

 black vittse. Elytra elongate-oblong, very long compared with 

 the thorax, apex of each briefly sinuate-truncate ; surface punc- 

 tured, some of the punctures in rows, and these latter each covered 

 by a black spot, and emitting a short bristle ; the colour is tawny 

 brown ; beyond the middle is an undulated blackish fascia, 

 and before the middle, on the suture, is a round white spot ; 

 besides which there are a few white specks on the sites of the 

 faint dorsal carinse, and an irregular thin white fascia near the 

 apex. Body beneath clothed with fine silky iron-grey pile, the 

 sides of the abdomen spotted with tawny ashy. Legs reddish ; 

 thighs prettily variegated with grey ; tibise and tarsi ringed with 

 grey. Ovipositor of the female short. 



One example only, taken on a fallen bough in the forest at 

 Ega. It seems to be closely allied to the South- Brazilian Try- 

 panidius litigiosus of collections, which is also an (Edopeza^,
