A single male example only has been obtained. It is closely allied to L. centralis, 
but is larger, with a more dense pubescence, much more largely developed club to the 
antenne, and a more elongate head; the sexual characters are also different, the hind 
legs being longer and thicker and with their tibie dilated externally below the middle, 
the middle femora without a patch of pubescence, and the denticle near the extremity 
of the middle tibize scarcely to be detected. 
I have named this elegant species of Pselaphide in honour of Herr Reitter, of Vienna, 
who has contributed more than any other entomologist to our knowledge of this family 
of minute but extremely curious Coleoptera.

LISTRIOPHORUS. 
Listriophorus, Schaufuss, Nunq. Otios. ii. p. 245; Reitter, Verh. Ver. Briinn, xx. p. 189 (1882). 
This genus has not been characterized; it was merely tabulated by Schaufuss. 
Listriophorus comprises only one species, which probably may not belong to our 
region.
