BRITISH BEETLES. 
often found at the bottom of the burrow. It flies -but 
seldom, and produces a considerable noise by rubbing 
the abdomen against the hinder margin of elytra. It 
occurs near Greenwich Park, at Bath, &c. 
The species of Ontliophagus have nine-jointed an- 
tennas, some of the joints of the club being concave ; 
the last joint of the labial palpi scarcely visible ; and 
slender tarsi. They are mostly small and flattened ; 
with the thorax greenish-black, and the elytra lurid- 
brown chequered with black ; and are found gregari- 
ously in dung, especially in sandy places and near the 
coast, but they never dig burrows deep below the 
surface. At times certain of them have been observed 
in dead animals. 
The back of the head in the male is often armed 
with a broad thin horn, bent backwards ; of which 
there are, as usual, modifications in size. 
The Ajjhodiina are all small, oblong, and cylin- 
drical ; with the organs of the mouth (except the 
apex of the palpi) hidden by the clypeus ; the antennae 
nine- jointed ; the abdomen with six free ventral seg- 
ments ; the scutellum visible ; the metasternum of 
ordinary size; the intermediate coxae oblique, and 
approximated behiud ; two spurs to the apex of the 
tibiae ; and the club of the antennae flat. Their eyes 
are only slightly divided by the side of the head, and 
their elytra almost always entirely cover the apex of 
the body. 
The males differ from the females in the greater 
development of certain tubercles on the clypeus; in 
the greater bulk and lesser amount of punctuation of 
the thorax ; in the longer spine at the apex of the
