The legs are reddish, with the tips of the thighs, tibiae, and tarsi 

 dusky. The hind legs of the males are greatly elongated, but 

 their thighs are not very abruptly clubbed. 



Santarem and Obydos; generally on severed and hanging 

 sipos, or woody climbers, near the borders of clearings. It ap- 

 pears to be not uncommon in Cayenne, examples from which 

 country have been sent to me from Paris as A. sparsus of Dej can's 

 catalogue. 



5. Anisopodus pusillus, n, sp. 



A. obloiigus, griseus, fusco maculatus : thoracis spinis laterallbus 

 antice a lateribus vix distinctis, retrorsum spectantibus : elytris 

 apice breviter sinuato-truncatis ; angulis internis acutis, externis 

 productis ; carinis lateralibus obtusis : femoribus modice clavatis. 

 Long. 3 lin. 



Head brown. Antennse reddish, tips of joints dusky. Thorax 

 thinly clothed with grey pile, sides with rufous-brown patches, 

 and disk with two large rounded blackish spots ; lateral spines 

 large and acute, scarcely distinct anteriorly from the sides of 

 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-griseus, cano fuscoque punctatus : tho- 

 racis spinis lateralibus acutissimis, retrorsum curvatis, basi tumidis: 

 elytris apice utrinque bimucronatis : pedibus posticis femoribus 

 modice clavatis. Long. 5 j lin. § . 



Head clothed with shining tawny pile. Antennse 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
