The last genus ( Ozineus) seems to form the connecting link 
between the groups allied to Alcidion and the present genus, 
some of the species of Ozineus (e. g. O. mysticus and O. rotundi- 
collis) having very much the general appearance of Anisopodi. 
The absence of the centro-basal ridges of the elytra, and the 
elongation of the hind legs, however, amply distinguish Aniso- 
podus from the four preceding genera. 
1. Anisopodus phalangodeSj Erichs. 
Leptoscelis pJialangodes, Erichson, Consp. Ins. Col. Peruana, p. 145. 
A. “ oblongus, planus, badius, dense cinereo pubescens, infra lateri- 
bus nigro vittatis : elytris seriatim fusco punctatis, apice mucro- 
natis : pedibus posticis fortiter elongatis, femoribus abrupte cla- 
vatis. Long. lin.” (Erichs. 1. c.) Eastern Peru. 
This species is distinguished from its congeners, to some of 
which {A, arachnoides, A. cognatus) it is very closely allied, by 
the sides of the breast and the abdomen being marked each with 
a streak of a sooty-brown hue (extending to the deflexed margin 
of the elytra), which, from the silky nature of the pile that 
clothes the under surface of the body, is fainter in some lights 
than in others, and in small examples is scarcely perceptible. The 
site of the centro-basal ridges of the elytra is marked by a small 
rounded tubercle coloured black. The male is much larger than 
the female, reaching 5 J lines in length, the female being seldom 
longer than lines. The hind legs in the male are sometimes 
10 lines long. Besides the black spot on the elytra over the 
centro-basal tubercle, there is, in the males, a larger and irre- 
gular spot on the disk of each towards the apex, and in most 
specimens a small lateral streak on the edge of the lateral carina 
a little behind the middle; this latter, however, never extends 
towards the disk of the elytra, as does the similarly placed spot 
in A. arachnoides, A. cognatus, and^. sparsus, A. phalangodes also 
differs from its relatives in the shape and direction of the lateral 
thoracic spine, this being large, robust, and prominent, directed 
obliquely towards the edge of the humeral angle of the elytra, 
and not standing at right angles to the side of the thorax, as in 
A. arachnoides, or having its point directed in continuation 
of the thoracic outline, as in A. cognatus. Both angles of the 
truncation of the elytra are mucronate. 
The species occurred, sometimes abundantly, on the boughs 
of fallen trees, in moist hollows of the forest at Ega, Upper 
Amazons. I could not ascertain the special use of the elongated 
hind legs of the male. Like all the species of this and the allied 
genera, the insects pass their lives on the bark, their larvse feed- 
ing and undergoing their transformations between the bark and 
the wood, and the perfect insects rambling on the outside of the
