Unfortunately during my visit to the Florence Museum, the Di-
rector, Signor Giglioli, was absent from the city and I was not able to
find the type of this species, but the specimen above described, obtained
at the same place as the type, is a co-type, and therefore is an accept-
able representative of the species.
