e sufficient to give the
numbers of those which we were able to collect during the short period
of our stay:--these were, _Elater_, 37; _Lampyris_, 17; _Ateuchus_, 14
(including the _Deltachilum_ and _Eurysternus_); _Passalus_, 13;
_Anoplognathidae_, 14; _Helops_, (including _Stenochia_ and _Statira_)
17; _Curculionidae_, 108; _Cerambycidae_, 101; _Cassida_, 24; _Haltica_,
26; _Doryphora_, 12; _Colaspis_, 15; and _Erotylus_, 12. The _Phanaeus_,
according to MacLeay, distinguished by the total absence of claws from
the feet, is peculiar to the warmer parts of America: _Onthophagus_ is
not met with along the shore, but is found in the interior. Such large
_Copris_ as are seen in the old world, (_Isidis_, _Hamadrias_,
_Bucephalus_,) have not been discovered here: their place is supplied by
the large _Phanaei_, _Faunus_, _bellicosus_, _lancifer_, &c. A
golden-green _Copris_ is a great rarity. _Onitis_ seems to be quite
wanting in America: all the specimens, in this part of the world, that
have been placed in that class, belong partly to the _Phanaeus_, and
partly to the _Eurysternus_ Dalm. a remarkable species of the genus
Ateuchus.

The _Ateuchi_ are not less numerous in South America than in Africa;
and here is found what may be looked upon as the intermediate link
between _Copris_ and _Onitis_. No part of the world is so rich in
_Rutelides_ as trophical America; and according to the narrow limits
within which Mac Leay confines this family, it would seem to be
exclusively restricted to this continent. The greater part have not the
head divided from the head-shield by a line, and the breast is
lengthened in front into a spine: this extensive division is peculiar to
America. In the second division, the head-shield of which is bounded by
a strongly marked line, those which are provided with a breast-bone are
American. South America possesses also the intermediate genus between
the _Rutelides_ and _Scarabaei_, in the genus _Cyclocephala_,
_Anoplognathidae_ were hitherto known to us from New Holland, Asia, South
Africa, and South America, and are characterised by the drooping form of
the upper-lip, falling lowest in the middle, and by the inequality of
their claws; the under-lip, at the same time, has either a projection in
the centre, or consists of two parts lapping over one another. In the
same way that the _Anoplognathidae_ of New Holland have the appearance of
_Rutelides_ proper, are the South American _Anoplognathidae_
