A few Corrections to Henshaw's Check List. 

 By E. a. Schwarz. 

 Calosoma tepidum Lee, is not a variety of 6yv//1'////;/ but a distinct 

 species. 



Tachys nigriceps Dej. , is to be stridden off, = Perigona ni'gri- 

 ceps, Dej. 



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

 n\mous witli A. scriatus and, I tliink, quite correctly so. 



Agabus congener Payk. and A. ambiguus Say (ovoideus 

 Lee). Tliis nomenclature adopied 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. 

 ainbigims Say. 

 A. confinis Gyllli. 



oToich'iis, Crotch. 

 Moreover, A. conjinis should be inserted immediately before in/tis- 

 ca/i/s 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. ^lisc. Coll., 140), but has never. been backed by a 

 description, and is therefore to be stricken ofi". 



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

 Ptilium fungi Lee, appears twice in the List, once ^s Natio'sella 

 and a second time as Piiliiim. 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 IMatthew'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 Micridhim was introduced in the 2nd edition of the "Classifi- 

 cation.'" 



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 of his species (cf 

 ]\Iannerheim, 3ter Beitrag zur Kaferfauna etc., p. no). 



Cis bicarinatus INIann., read C. hiarmaius. This is one of those 

 typographical errors which are likely to be perpetuated in future editions 

 of the List.
