92 MIMICRY, AND OTHER PROTECTIVE 
and armed with powerful jaws, as well as having some 
disagreeable secretion. Some species of Kumorphide 
and Hispide, small flat or hemispherical beetles which 
are exceedingly abundant, and have a disagreeable se- 
cretion, are imitated by others of the very distinct 
group of Longicornes (of which our common musk- 
beetle may be taken as an example). The extraordi- 
nary little Cyclopeplus batesii, belongs to the same 
sub-family of this group as the Onychocerus scorpio 
and O. concentricus, which have already been adduced 
as imitating with such wonderful accuracy the bark 
of the trees they habitually frequent ; but. it differs 
totally in outward appearance from every one of its 
allies, having taken upon itself the exact shape and 
colouring of a globular Corynomalus, a little stinking 
beetle with clubbed antenne. It is curious to see how 
these clubbed antennz are imitated by an insect be- 
longing to a group with long slender antenne. The 
sub-family Anisocerine, to which Cyclopeplus belongs, 
is characterised by all its members possessing a little 
knob or dilatation about the middle of the antennex. 
This knob is considerably enlarged in C. batesii, and 
the terminal portion of the antenne beyond it is so 
small and slender as to be scarcely visible, and thus an 
excellent substitute is obtained for-the short clubbed 
antenne of the Corynomalus. Erythroplatis corallifer 
is another curious broad flat beetle, that no one would 
take for a Longicorn, since it almost exactly resembles 
Cephalodonta spinipes, one of the commonest of the 
South American Hispide; and what is still more
