Para, on felled trees in broad roads tbrongb the forest. The 
terminal ventral segment in both sexes is broadly truncated, 
with a distinct spine at each angle. M. Guerin-Meneville (Icon. 
Regne Animal, p. 243) believes this species to be the same as 
the T. subocellatus of Olivier (Ent. no. 67. pp. 69, 89, pi. 2. 
f. 12 a, h)j and that the latter is founded on a worn or immature 
individual.

T. nigro-velutinus, capite fascia utrinque infra oculos, vitta laterali, 
alteraque coronali per thoracem et scutellum continuata, vittaque 
elytrorum utrinque medio interrupta et maculiformi laete flavis ;

This species, originally discovered in the wooded plains of 
Bolivia by M. D^Orbigny, was common on the Upper Amazons 
at Ega. The yellow (partially macular) stripe of the elytra 
varies a little in the degree in which it is broken up into spots ; 
but it never forms a double row of distinct round spots from 
base to apex, as shown in T. decoratus, and can scarcely be con- 
sidered a local form of the same stock.

T. niger, capite linea curvata frontali, vitta utrinque laterali, altera 
coronali per thoracem scutellum et elytros continuata (hie dentata) 
pallide flavis ; thorace utrinque linea tenuissima grisea ; elytris

bus anticis valde elongatis, tibiis curvatis, tarsis baud pilosis.

A common insect in the forest at Ega, on the Upper Amazons. 
It is probably a local form of T. scalaris, Fabr., but differs much 
from the description given by that author. The terminal ventral 
plate is formed as in T, decoratus.

T, niger, griseo vestitus ; capite thoraceque lineis tenuibus tribus, 
elytris maculis numerosis parvis, flavo-griseis, his apice acutis ; 
corpore subtus flavo maculato : maris pedibus anticis valde elon-

This species was a rare one in the Amazons region, and found 
only in the dry forests of the Tapajos. The spines of the ter- 
minal ventral segment are more elongated than in the other 
species.
