(the genuine Canibus obscurus, Fab.) ; O. punclatulus and nitidulus 

 are mutually identical, and the same as H. punctatulus, Dej. ; O. 

 punctatissimus may perhaps be subcordatus, Dej.; . foraminulosus 

 appeared to me to belong to puncticollis, Payk., Dej., and O. pu7ic- 

 ticeps to be a small variety of the same species, whilst O. puncticollis, 

 subpunctatus and cribellum might answer for the H. brevicollis, Dej. 

 I will not however give out these statements as absolutely certain. 



Stenolophus Skrimshiranus might perhaps correspond with the S. 

 melanocephalus, Findel, which is described by Dejean as a variety of 

 S. vaporariorum, but I am not convinced that it is so. 



Most of the specimens of Trechus dorsalis in the Stephensian col- 

 lection belonged to Stenol. elegans, Dej. ; Ti echus parvulus is an im- 

 mature St. dorsalis, Dej. ; T. Jlavicollis is Acup. luridus, Dej., but not 

 T. flavicollis, Sturm ; T. nitidus is identical with the preceding ; T. 

 ruficollis is Brady cellus similis, Er., and T. placidus the Brady cellus 

 placidus, Er. ; T. suturalis is Acup. cognatus, Gyll., Dej. The spe- 

 cimens with a reddish thorax which are mentioned in Stephens's 

 descriptions belong to placidus, Gyll. ; I cannot distinguish T. fulvus 

 from Acup. Harpalinus, Dej.; T. pallidus is founded on immature 

 specimens of the same species. 



T. brunnipes is a species of Bradycellus not otherwise known to 

 me, nearly allied to B. Harpalinus, and distinct from Stenol. brun- 

 nipes, Sturm, Er. ; T. consputus and meridianus are the species so 

 called by Erichson ; T. cognatus is nothing but a specimen of T. me- 

 ridianus; T. aquaticus, with its varieties T. fuscipennis and tristis, is 

 identical with T. minutus, Er., and T. ItEvis is a large specimen of the 

 same species. 



Blernus paludosus is Dejean's Trechus of the same name; B. pal- 

 lidus answers exactly to the description of Trechus fulvus, Dej., but 

 does not agree with T. pallidus, Sturm. Of the true B. longicornis, 

 Sturm, I have seen no English specimen. 



Lymnceum nigropiceum is a very marked sjjecies, which was pre- 

 viously quite unknown to me. 



Tachys scutellaris is the same as Bemb. scutellare, Dej. ; T. hino- 

 tatus and vittatus the same as B. guttula, Dej., Er. ; T. inermis, pu- 

 sillus, obtusus and gracilis belong to B. obtusum, Sturm, Dej. ; T. mi- 

 nutissimus and perhaps also T. minimus, Curt., which I have not seen, 

 are identical with B. bistriatum, Dej. ; T. maritimus is not in Ste- 

 phens's collection. 



Philochthus aneus is Bemb. aneum. Germ. ; P. Doris, subfenestratus 

 and biguttatus appeared to me to belong to B. vulneratum, Dej. ; and 

 P. guttula to B. biguttatum. The typical specimen of 5. hcemorrhoum, 

 Kirby, is a B. guttula, Dej. Specimens of D. obtusum have been con- 

 founded with it by Stephens. 



Ocys currens is Bemb. pumilio, Dej.; O. melanocephalus and tem- 

 pestivus are the same as B. rvfescens, Dej. 



Peryphus femoratus and concinnus appeared to me to belong to 

 Bemb. Bruxellense, Putz., and the second is certainly different from 

 B. concinnum of Putzeys. Under P. maritimus several species are 

 confounded ; of the four specimens in the Stephensian cabinet, two
