286 Mr. H. W. Bates on the Longicorn Coleoptera 



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. elongatuSj planus, griseus, fusco punctatus : elytris dimidio api- 

 cali nigro, cano notato, apicibus utrinque bispinosis : pedibus pos- 

 ticis maris maxima elongatis, tenuibus, femoribus abrupte clavatis. 

 Long. 4^ lin. 



Head dusky. Antennae 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 

 a dull pinkish-grey hue, spotted with dark brown, whilst the 

 apical half is dull black, with a few greyish marks. Body be- 

 neath clothed with silvery ashy pile. Legs slender ; all thighs 

 abruptly clubbed, the fore and middle pair having on their 

 under side near the base a small tooth ; they are of a dusky hue, 

 with the base of the femora pallid. The hind legs in the male 

 (the only sex known) are extremely long and slender. 



Of this elegant species I found only a single example at S. 

 Paulo, Upper Amazons. 



8. Anisopodus gracillimus, n. sp. 



A. oblongus, gracilis, olivaceus, nigro punctatus-: thoracis spinis late- 

 ralibus retrorsum curvatis, basi tumidis : elytris apice utrinque 

 bidentatis, pone medium nigro undulato-fasciatis : pedibus pos- 

 ticis ( c? ) fortiter elongatis, femoribus abrupte incrassatis. Long. 

 2f-4 lin. 



Head olive-green. Antennse blackish, base of joints reddish. 

 Thorax with the sides dilated and tumid before the spines, which 

 latter consequently appear curved, and are placed close to the 

 hind angles; the pile of the surface has an olive-green hue, 

 leaving three blackish streaks in the middle — two touching the 

 front margin, and one, lying between the anterior two, the hind 

 margin. Elytra with both angles of the truncation produced, 

 but not to a notable length, the external one longest; lateral 

 keels obtuse ; surface olive-green, spotted with blackish, an un- 

 dulated fascia of the same colour crossing the middle, and two 

 small patches lyiug on the sides, namely, one near the base, and
