ultimo excepto. Prothorax in utroque sexu cylindricus, 



capite baud latior. Elytra sub-elongata, parallela, apicibus 



acuminatis vel rotundatis. Pedes graciles, elongati, prae-

An elegant genus, only known before Mr. Wallace's researches 



by a single species, and at once distinguished from any of the 



preceding, except Olene cam plus, by the non-existence of a cicatrix 



on the scape, and from that it is well separated by the great length 



of the posterior legs, which, except in one species, are longer than 



the anterior, an unusual character in the sub-family. The species 



vary greatly in colour, but are all finely pubescent.
