 The type of N. aquaticus J Kirby, examined by Dr. LeConte in the British

 Fauvel. Pr., 1853, 322.

 ern and central Europe, eastern Siberia (Mt. Morikan, Ajansk on the 

 east coast) ; Vega Exi>ed., 47. Heyden, 14. Not in European catalogues. 



20. Dyschirius seneus Dej., frigidus Mann., integer, dentiger Lee. — This syn- 



onymy is cited by Mr. Fauvel from his Faune Gall. Ehen. iii, 145, 1868. 

 It appears to have been either unobserved, or disregarded by Dr. 

 LeConte. Integer and dentiger are species in Dr. LeConte's first syn- 

 opsis of the genus (Pr. 1857, 75 pp.), but in his second (Bull. Brook. 

 1879, ii, 17 and 31), integer, is retained as a species, while dentiger is 

 united with pumilus Dej., as are also falciger and rufiventris I^ec. These 

 determinations he permitted to stand in Mr. S. Henshaw's index to the 

 species described by Dr. LeConte (T. ix, 207, 1881). In view of the fore- 

 going, further observation seems requisite. Aeneus occurs in Europe, 

 Siberia, Dauria, Japan. Heyden, 16; Fauv, Rev. 96; frigidus, in Kenai,
