tenuissima griseo-sericea vestitis, lateribus fasciaque pone medium 
nigerrimis, pedibus piceo-rufis. Long. 43 lin. 
I met with two examples of this insect, namely on a slender 
branch of a tree in the forest at S. Paulo, Upper Amazons. 
Genus Scopapus, Pascoe, 
Pascoe, Trans. Ent. Soe. n. s. vol. iv. p. 100. 
This genus resembles Omosaroées in its elongate shape and 
Cerambycideous aspect; but its antenne are much elongated, 
filiform to their apex, and nearly naked. The groove of the an- 
terior tibiz, which is the invariable character of the Lamiaires, is 
scarcely perceptible, so that, were it not for the vertical face, 
square muzzle, and pointed palpi, it might be doubted whether 
the genus would not have its true place amongst the Ceramby- 
cide ; the groove, however, on careful examination, is seen to be 
present. The legs are elongated ; the thighs very abruptly club- 
bed, the tibize slender and linear, and the tarsi short, with the 
basal joint triangular. The anterior and middle coxe are glo- 
bular, the sterna very narrow, and the anterior sockets angulated 
on their outer side. As in Omosarotes, the elytra have raised 
centro-basal ridges surmounted by a pencil of hairs; on the 
outer side of each ridge lies an oblique linear depression, ex- 
tending from the inner side of the prominent shoulder to the 
middle of the suture.

On stem of dead tree, Ega; three examples. 
Genus Esmra, Pascoe. 
Pascoe, Trans. Ent. Soe. n. s. vol. 1. p. 44. 
Like the three preceding genera, the present has an elongate 
form of body. The antennz are a little longer than the body, 
and have the basal joint and the third and basal half of the fourth 
joints thickened and densely clothed with hairs ; the fifth joint 
has also a dense patch of hairs on its upper surface; the third 
and fourth joints are greatly elongated ; the rest of the antenne, 
body, and legs are clothed less densely with shorter hairs. The 
front of the head is vertical, and the muzzle quadrate. The 
thorax is short, subquadrate, and armed on each side with a tu-
