34 Dr. Schaum on the British Geodephaga. 



D. obscuroguttatus, Duft., spilotus, Dej. D. angustatus and maurus 

 are not distinct, and both=Z). maurus, St. 



Lamprias (Lebia) nigritarsis does not appear to me to differ from 

 L. cyanocephala, nor L. rufipes from L. chlorocephala. 



Tarus humeralis is Dejean's Cymindis of the same name. T. macu- 

 laris and axillaris are mutually identical, and perhaps only a variety 

 of C humeralis with a dark red prothorax ; at all events quite distinct 

 both from C. macularis, Dej., and C. axillaris, Dej. T. coadunatus, 

 IcBvigatus, homagricus and angularis again form one species, w^hich is 

 identical with C. homagrica, Dej . T. basalts is the Gyllenhalian spe- 

 cies of the same name. It appears consequently that there are three 

 species of Cymindis indigenous to England — C humeralis, homagrica 

 and basalis. 



Brachinus crepitans. — To this species, the specimens named in 

 Stephens's collection B. immaculicornis, explodens and glabratus ap- 

 peared to me to belong. 



Almost the whole of the English species of the genus Dyschirius 

 are known on the continent under other names ; only B, nitidus, 

 politus, ceneus and gibbus of Stephens are, the first probably, and the 

 three others certainly, the like-named species of Dejean and Putzeys. 

 Of the others, D. minimus is the same as B. gibbus ; B. pusillus, ova- 

 tus and thoracicus are not distinct from B. aeneus ; B. tristis is a spe- 

 cimen of the same species inclining, in colour, to blue ; B. rufipes 

 and punctatus are the same as B. salinus, Schaum, Putz. ; B. areno- 

 sus is an immature specimen of the true B. thoracicus, Fab., Er., 

 Putz.*; B. cylindricus the same as B. politus, and B. inermis, digi- 

 tatus andfulvipes form one species, and are identical with B. areno- 

 sus, Putz. (non Steph.). Putzeys has been misled, by an incorrectly 

 determined specimen in Hope's collection, into describing this marked 

 species (which I found in plenty on the sea-shore near Swinemiinde - 

 in the summer of 1845) as B. arenosus, Ste. The name B. inermis, 

 under which Curtis has so beautifully figured it, will be retained 

 for this species. 



The English specimens of Nebria livida all belong to A^. lateralis, 

 Fab. : the true N. livida is not indigenous in England. 



Helobia (Nebria) lata, Newm., is, according to the original spe- 

 cimens, only a rather large variety of H. brevicollis, and H. vari- 

 cornis, Newm., is described from immature specimens of the same 

 species. H. cethiops, Ste., is a large specimen of Gyllenhalii, Schonh., 

 of which H. Marshallana, Ste. (arctica, Dej.) is an alpine form. 



Leistus nigricans, Newm. — The original is an old, dark specimen 

 of L. spinibarbis. L. Janus, Newm., is described from immature 

 specimens of L.fulvibarbis, Dej. Leistus montanus, Ste., is a very 

 marked species of this genus, apparently unknown on the continent. 

 L. indentatus, Newm., is unknown to me, as I have not seen the ori- 

 ginal specimen ; it is most probably not a distinct species, and the 

 depression described merely accidental. 



* This was the only specimen of this species (Z). thoracicus, Fab.) in 

 Stephens's collection ; it is not rare in England however, and has been taken 

 by Wollaston in great plenty.
