Obs. This singular insect has an affinity to Sagra, but differs from that
genus in having setiform antennae, porrect mandibles, and securiform
palpi. Its habit is also totally different from that of a Sagra, and more
like that of some of those insects which belong to the heterogeneous
magazine called Prionus. It is, undoubtedly, the most singular and novel
form in Captain King's collection, and forms a new genus, of which the
characters are as follow.
