one near the apex. Body beneath of an olive-ashy tinge. Legs 

 dusky^ base of thighs pale. Hind legs of the male greatly 

 elongated ; the thighs much more thickly clubbed in the male 

 than in the female. 



Taken once abundantly on dried twigs in the forest at Ega. 



9. Anisopodus ligneus, n. sp. 



A. oblongo-ovatus, fulvus, strigosus : thoracis spinis lateralibus co- 

 nicis, prope angulum posticum sitis : elytris postice valde attenu- 

 atis, apice peroblique truncatis, angulis externis mucronatis ; fe- 

 moribus abrupte clavatis. Long. 4^-5 lin. 



Head tawny brown, vertex spotted with dark brown. An- 

 tennae reddish, tips of joints dusky. Thorax rather short, 

 coarsely punctured, the lateral spines conical, and placed very 

 close to the hind angles ; colour tawny brown. Elytra rather 

 oval in shape, rapidly attenuated from three-fourths their length 

 to the tip ; the tip is consequently pointed, and the truncation 

 so short that each elytron may be said to end in a spine notched 

 on the inner side, instead of being obliquely sinuate-truncate ; 

 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 punctui'ed, 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. Rare. 



10. Anisopodus lignicola, n. sp. 



A. oblongo-ovatus, cinereo-ochraceus, humeris fulvescentibus : tho- 

 racis spinis lateralibus magois, acutis, obliquis : elytris postice valde 

 atteimatis, apice peroblique sinuato-truncatis, subplanis, punctatis. 

 Long. 3 lin. 



Head reddish. Antennae 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 punctui-ed, 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
