the thorax, and pointing obliquely towards the humeral angles 
of the elytra. Elytra oblong, the lateral keels not sharp, and 
hence the surface apparently less flattened than in the preceding 
species ; apex moderately mucronated ; surface greyish, with a 
moderate number of rather large round brownish spots more or 
less confluent, one on the site of the centro-basal tubercles 
(which are quite absent), and another, lateral, near the middle 
of the elytra, being larger than the others. Body beneath and 
legs reddish. The legs are rather slender, and the thighs not 
abruptly, although distinctly clubbed. 
This small and delicate species was found only at Para. 
6. Anisopodus elongatus^ n. sp. 
A, elongatus, ellipticus, fulvo-griseiis, cano fuscoque punctatus : tho- 
racis spinis lateralibus acutissimis, retrorsum curvatis, basi tumidis: 
elytris apice utrinque bimucronatis : pedibus posticis femoribus 
modice clavatis. Long. 5| lin. $ . 
Head clothed with shining tawny pile. Antennae reddish, 
tips of joints dusky. Thorax with the sides rather dilated and 
tumid at the base (on the fore side) of the lateral spines, which 
appear curved posteriorly, and have very acute points ; disk 
punctured, tawny brown, with a short polished dorsal line and 
two discal black spots edged with light grey. Elytra narrow 
and greatly elongated, both angles of the truncation produced 
into spines; lateral carinse rather obtuse, surface punctured, 
except near the apex, and of a tawny-brown hue, with three 
rows of alternate whitish and brownish spots, besides a sutural 
row of brown and grey specks. Body beneath and legs pale 
brown; hind thighs moderately clubbed in the female. 
Found only at Ega, Upper Amazons. 
7. Anisopodus macropus ^ n. sp. 
A. elongatus, planus, griseus, fusco punctatus : elytris dimidio api- 
cal! nigro, cano notato, apicibus utrinque bispinosis : pedibus pos- 
ticis maris maxime elongatis, tenuibus, femoribus abrupte clavatis.

Head dusky. Antennse rust-coloured. Thorax rather long, 
narrow in front, sinuated on each side, and then abruptly di- 
lated, the dilatation terminating at the apex of the spine, which 
is obtuse, and points towards the hind angle; the surface is 
punctured, and has an impressed dorsal line, the colour being 
obscure greyish, with four indistinct oblong sooty spots not 
reaching the hind margin. Elytra elongate, narrow, flattened, 
although having the lateral keels obtuse ; the apex transversely 
sinuate-truncate, with both angles spiniform ; their surface is 
covered with equidistant punctures, and is, on the basal half, of
