Published online by Cambridge University Press: 31 May 2012
Extract
The W. S. Blatchley collection of Coleoptera, now at Purdue University, Lafayette, Indiana, contains thirteen primary types of Hydradephaga described by Blatchley. Some of the species represented have not been recognized by subsequent workers, while others have been synonymized without the original types having been seen. The following notes and comments therefore seem pertinent, and may prove of value to others engaged in the study of this group of insects.
