Type locality.—Jacksonville, Florida. Types. No. 24594, U.S.N.M. Redesoribed from one specimen of the type series in the United States National Museum.

There are three specimens in the type series but two of them, representing as many species, do not agree with the original description. Each of them has the second tergite distinctly less than twice as long as wide. They remain undesoribed, being in rather poor condition.
