58 COLEOPTERA. 



23. Stenus nigritulus, Gyll., Ins. Suec. iv. 502, 10 — 11 



{nee Erichson) ; Thomson ; G. R. Crotch, Cat. Brit. 

 Col. ; E. C. Rye, Ent. M. Mag. vol. i. p. 87. 

 unicolor (Kirby) Stephens; Wat. Cat. 

 campest?'L^, Erichson. 

 The only wonder connected with this change is that 

 Gyllenhal's admiiable description should for so long a time 

 have been misconstrued, and by such a nian as Erichson. 



24. Stenus crassus (Kirby), Stephen??, 111. Mand. v. 287, 



18 (1832), and coll.; E. C. Rye, Ent. M. Mag. 

 vol. i. p. 86. 

 C7'af<siventris, Thomson (1857), G. R. Crotch, Cat. Brit. 



Col. 

 nigritulus, Er., Wat. Cat. (7iec Gijll.) 

 As the mgritulus of Gyll. is now found to be distinct from 

 that of Erichson, a new name for the latter is required ; and 

 Stephens' crassus, being long anterior to Thotnson's crassi- 

 ventris, must stand. His description is good, and corrobo- 

 rated by type in his collection. 



25. Stenus littoralis, Thomson, Skand. Col. ii. 226, 



30 ; G. R. Crotch, Cat. Brit. Col. ; E. C. Rye, Ent. 

 M. Mag. vol. i. p. 86. 

 I see no reason to alter my opinion that this insect is not 

 specifically distinct from S. crassus (nigritulus, Er.) 



26. Stenus bifoveolatus, Gyll., Ins. Suec. iv. 500, 9 — 10 



{iiec Erichson) ; Thomson ; G. R. Crotch, Cat. Brit. 

 Col. ; E. C. Rye, Ent. M. Mag. vol. i. p. 89. 

 nitidus {Kirhy), Stephens; Wat. Cat. 

 jdancus, Erichson. 

 The same remarks apply to this as to No. 23.
