A few Corrections to Henshaw's Check List. 

 Jiv E. A. Schwarz. 



Calosoma tepidum Lee. , is not a variety of calidum but a distinct 



species. 



Tachys nigriceps Dej. , is to be stricken oft", = Perigona nigri- 

 ieps, Dej. 



Agabus parallelus Lee, is considered by Dr. Sharp as syno- 

 nymous with A. seriatus and, I think, quite correctly so. 



Agabus congener Payk. and A. ambiguus Say (ovoideus 

 Lee). This nomenclature adopted by Mr. Henshaw leads to confusion 

 and is neither in accordance with that given by Dr. Sharp, nor with Dr. 

 Horn's subsequent remarks (Trans. Amer. Ent. Soc. , X, p. 278). The 

 two species should stand as follows : 



A. congener Payk. 

 ambiguus Say. 

 A. confinis Gyllh. 



ovoideus, Crotch. 



Moreover, A. confinis should be inserted immediately before infus- 

 catus Aub., with which it forms a well-defined group, characterized by 

 the acute ridge on the prosternal process (cf. Sharp, On Aquat. Carniv. 

 Col, p. 520). 



Scydmaenus cautus Lee. This name appears first in Dr. Le- 

 conte's List (Smithsn. Misc. Coll., 140), but has never been backed by a 

 description, and is therefore to be stricken oft". 



Gymnusa variegata Kiesenw., is to be added after G. brevicollis. 



Ptilium fungi Lee., appears twice in the List, once as Nanosella 

 and a second time as Ptilium. The latter reference should be stricken oft'. 



Ptenidium Ulkei Matth. This is the species formerly known to 

 us as aiomaroides Mots. With the literature at my command I fail to 

 find a description of Motschulsky's species, but if it is described the name 

 has preference over Matthew's name. If it is only a MS. species, it 

 should be dropped from the List. 



Ptenidium ? lineatum Lee. I think it was for this species that 

 the genus Micr'idium was introduced in the 2nd edition of the "Classifi- 

 catii >n. v 



Cybocephalus unicolor Mots. If this name is to be retained at 

 all it should at least be transferred to the genus Cercyon in accordance 

 with the author's own opinion, regarding the lost type ofhis species (cl 

 Mannerheim, 3ter Beitrag zur Kaferfauna etc., p. 110). 



Cis bicarinatus Mann., read C. biarmalus. This is one of tl 

 typographical errors which are likely to be perpetuated in future editions 

 of the List.
