* I am indebted to Mr. E. A. Sehwarz for the following " Synonymical Note. 

 From Dr. LeConte's very lucid original description of Bryaxis conjwicta it is evi- 

 dent that this name should be retained for the species whicli in tbe % has strongly 

 clavate antennie, spinous anterior trochanters, etc. In his earlier studies on 

 Pselaphids. Dr. Brendel became aware that there were two species confounded 

 under B. conjiincta. but the new species characterized by him as B. clavata is pre- 

 cisely identical with B. conjimctu Lee, whereas what he sup])osed to be the true 

 B. conjuncta is characterized by him as having, in the % , less clavate antenn;e 

 and unarmed trochanters. For reasons unknown to me all subsequent writers on 

 Pselaphids, including Dr. LeConte himself, have adopted Brendel's nomenclature. 



The synonymy of the two species stands as follows : 



1. Bryaxis conjuncta LeConte, Bost. Journ. Nat. Hist., vol. vi, 85. 1850. 



conjuncta var. claratn Brendel, Proc. Ent. Soc. Phila., vol. v, 256, 1865.

 A new name has to be coined for the second species."— E. A. Schwakz.
