550 Mr. T. Vernon Wollaston on the 
that there is a second spine, from the inner angle of the 
tibia, of ahnost equal length, besides an additional smaller 
one betAveen the elongated central one and the outer 
angle, — an anomalous structure (amongst the Cossonids), 
which causes the whole apex to be essentially spinulose. 
Yet there is a little indication of an irregularity of (at all 
events) partially the same character, in the (likewise 
African) genus Aoriis and the South-American Lipan- 
cylus, — which I have conseqviently placed in juxta-position 
with Amor])hocerus, and in which at any rate the terminal 
uncus appears (as it seems to me) to be obsolete. 
In other respects Anw7-phocerus is remarkable for its 
rather depressed, broadish, parallel- oblong, posteriorly- 
obtuse body, dark hue, and very deeply (though not very 
densely) sculptured surface ; for its rostrum being parallel 
and somewhat robust, though not very long ; for its pro- 
thorax being largely developed, though not wider (at its 
broadest part) than the elytra, and but very little con- 
stricted in front ; and for its antennre, which are implanted 
considerably behind the middle of the rostrum) being 
short and thick, — with the funiculus (the first joint of 
which is much enlarged) exceedingly solid and compact, 
and the club small and not at all abrupt. Its scutellum is 
very conspicuous, and the third articulation of its feet is 
considerably expanded and bilobed. 
58. LiPANCYLUS {?iov. gen.). — I am indebted to 
Mr. Jan son for the loan of the very extraordinary insect 
for which the present genus is established, and Avhich is 
South- American, — it having been taken, I presume by 
Mr. Bates, in the region of the Amazon. I have not the 
slightest doubt that its true affinities are with Aorus from 
western Africa, — with which it agrees in the most ano- 
malous character (for the CossonidcE) of its tibial hook 
being obsolete, as well as in its elongated, extremely 
slender and cylindrical (though less curved) rostrum, its 
narrow, parallel body (which, as in that genus, will be 
seen, when viewed beneath a high magnifying power, to 
be not altogether bald), in its unconstricted prothorax, its 
wide and greatly developed feet (the third joint of which 
is much expanded and bilobed), its minute claws, and 
in the fact of its long and thickened legs being more 
approximated at their base than is usual in the members 
of this family. Nevertheless, although approaching Aorus 
in so many important respects, Lipancylus has an abun-
