' Credited to Parreyss in Utt. 



2 Specimens received from Mr. Bednall bearing the above name are undoubtedly a 

 form of D. australis. I do not know whether it has been described or not. 



•''The types are in the U. S. National Museum collection. Lea believes it to be the 

 same as the australis. I am inclined to think it distinct.
