the lateral keel is sharply marked, the surface is marked with 
several (seven or eight) slightly raised lines extending from the 
base to near the apex, but most of them bent near the base, and 
with as many corresponding depressed lines between them, the 
latter of which are thickly punctured, whilst the raised lines are 
impunctate ; the colour is of a tawny-brownish hue, the base 
being dusky, and the apical third of a deeper tawny hue — the 
whole giving to the insect a striking resemblance to a chip of 
wood. Body beneath and legs reddish. Thighs abruptly clubbed; 
hind legs of the male greatly elongated. 
Taken in the forests of the Tapajos and at Ega. Bare. 
10. Anisopodus lignicola, n. sp. 
A. oblongo-ovatus, cinereo-ochraceus, humeris fulvescentibus : tho- 
racis spinis lateralihus raagnis, acutis, obliquis : elytris postice valde 
attenuatis, apice peroblique sinuato-truncatis, subplanis, punctatis. 
Long. 3 lin. 
Head reddish. Antennse reddish, tips of joints dusky. 
Thorax ochraceous or yellowish ashy, with two obscure dusky 
lines on the disk ; the lateral spines large, thick, directed obliquely 
rearwards, the thorax behind the spines being much narrowed. 
Elytra narrowed to the tips, which are obliquely sinuate-trun- 
cate, the inner angles pointed, the outer spiniform ; the lateral 
keels are obtuse, but distinct; the surface is plane, but not 
notably depressed, minutely punctured, ashy-ochraceous in hue, 
with obscure spots and oblique fasciae (on the sides) of a darker 
colour, a triangular spot on each shoulder, extending over the 
scutellum, being of a ruddier ochreous tinge. Body beneath 
and legs of a tawny colour ; thighs moderately clavate. 
Para and the banks of the Tapajos. 
11. Anisopodus humeralis, n. sp. 
A. oblongo-ovatus, niger : thoracis lateribus humerisque fulvescen- 
tibus ; spinis lateralibus magnis, acutis, obliquis. Long. 3 lin. 
Head dusky, with the sides bright tawny. Antennse pitchy 
red, tips of joints dusky. Thorax with the sides shining tawny, 
the middle portion dusky, with two more distinct black dorsal 
stripes ; the spines as 'm A. lignicola — namely, large, acute, 
obliquely directed rearwards, and followed by a narrowing of the 
thorax to the base. Elytra oval, narrowed to the tips, which 
are obliquely sinuate-truncate, the inner angles pointed, and the 
outer spiniform ; the lateral keels are indistinct ; the surface is 
closely punctured, the colour sooty black, varied with a few 
ashy marks, the shoulders having each a triangular tawny spot, 
which does not cover the scutellum. Body beneath and legs
