Signatus is closely related to melanostictus and most of the distinguishing characters mentioned [in Fall (1915)] are really of little weight. It is exactly intermediate between melanostictus and livens, and appears to be quite as close to the latter, with which it nearly agrees in the slightly prominent eyes and general form and sculpture.
