fallen boughs, on which, after copulation, the females deposit 
their eggs. 
In the collection of Mr. Bakewell there is a specimen of this 
species from Cayenne, differing from Upper- Amazons examples 
only in the dark-brown points of the elytra being a little more 
distinct and encircled with grey. 
2. Anisopodus arachnoides, Serv. 
Anisopus arachnoides, Serville, Ann. Soc. Ent. Fr. iv. p. 31. 
A. oblongus, griseus, sericeus, fusco punctatus : thoracis spinis late- 
ralibus distinctis porrectis : elytris apice modice spinosis ; tuberculis 
centrobasalibus hirsutis ; lateribus atro-fuscis, maculis tribus adja- 
centibus, una pone medium, irregular!, majore ; pedibus posticis 
vix elongatis. Long. 4|-6 lin. 
Head brown. Antennse pitchy red, tips of joints (from the 
third) dusky. Thorax greyish, with two black spots on the fore 
part of the disk ; sparsely punctate ; the lateral spines standing 
out at right angles from the sides. Elytra transversely sinuate- 
truncate at the apex, the inner angle of the truncation pointed, 
the outer moderately prolonged as a spine ; the surface is grey, 
with scattered black points and a black pencil of hairs over the 
centro-basal tubercles : the deflexed sides are dark brown and 
silky, and, above, this colour extends in three irregular spots — 
one near the base, one after the middle reaching to the disk of 
the elytron, and one smaller near the apex. The underside of 
the body is silky ashy. The legs are dusky, ringed with grey. 
The hind legs of the male are only slightly elongated. 
The above description applies to a species which I have seen 
in collections at Paris under the name of A. arachnoides of 
Serville, and to which the description of Serville applies, as far 
as it goes. I found it on the same trees with A. phalangodes 
at Ega, and also met with it at Para. 
3. Anisopodus cognatus, n. sp. 
A. subellipticus, carneo-griseus, sericeus, nigro punctatus : thoracis 
spinis lateralibus unciformibus : elytris absque tuberculis centro- 
basalibus, apice breviter mucronatis, pone medium macula lateral! 
nigra obliqua notatis : pedibus posticis maris elongatis, fortiter 
clavatis. Long. 4 lin. 
Head brownish. Antennse pitchy red, tips of the joints dusky. 
Thorax greyish, fore part of the disk with two black spots, 
punctured ; the lateral spines pointing to the hind angles, their 
anterior sides (nearest the head) being continuous with the lateral 
outline of the thorax, and therefore giving them a hooked shape. 
Elytra sinuate- truncate at the apex, both angles of the trunca- 
tion pointed, but neither prolonged into a spine ; the surface is
