34 Dr. Schaum on the British Geodephaga. 
D. obscuroguitatus, Duft., spilotus, De}. D. angustatus and maurus 
are not distinct, and both=D. 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 agvilliaris 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. avillaris, Dej. T. coadunatus, 
levigatus, homagricus and angularis again form one species, which is 
identical with C. homagrica, Dej. T. basalis is the Gyllenhalian spe- 
cies of the same name. It appears consequently that there are three 
species of Cymindis indigenous to England—C. humeralis, wenn ae 
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 D. nitidus, 
politus, eneus 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 D. gibbus ; D. pusillus, ova- 
tus and thoracicus are not distinct from D. eneus ; D. tristis is a spe- 
cimen of the same species inclining, in colour, to blue; D. rufipes 
and punctatus are the same as D. salinus, Schaum, Putz.; D. areno- 
sus is an immature specimen of the true D. thoracicus, Fab., Er., 
Putz.* ; D. cylindricus the same as D. politus, and D. inermis, digi- 
tatus and fulvipes form one species, and are identical with D. 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 Swinemunde 
in the summer of 1845) as D. arenosus, Ste. The name D. inermis, 
under which Curtis has so beautifully figured it, will be retained 
for this species. 
The English specimens of Nebria livida all belong to N. 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. HH. aethiops, Ste., is a large specimen of Gyllenhalii, Schonh., 
of which HZ. 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. 
Di 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 (D. thoracicus, Fab.) in 
Stephens's collection ; it is not rare in England however, and has been taken 
by Wollaston in great plenty.
