38 Dr. Schaum on the British Geodephaga. 
belong to the preceding species, one to B. concinnum of Putzeys, and 
the fourth to B. rupestre, Dej.; B. tetraspilotus is wanting in Ste- 
phens’s collection. ‘I'wo specimens which Wollaston communicated 
to me under this name belonged-to B. rupestre, Dej.; P. littoralis 
is B. rupestre, Dej.; P. lunatus and ustus are B. lunatum, Duft., P. 
lunatus being established on immature and P. ustus on mature spe-— 
cimens of that insect; P. decorus and albipes correspond with P.. 
brunnipes, Dej., P. albipes being the young specimens; P. nitidulus, 
Marsh., is P. rufipes, Dej., and P. agilis the same as B. decorum, 
Dej. On the other species of the genus Peryphus I cannot venture 
to give any decided opinion. 
Notaphus undulatus is Bemb. undulatum, Dej., Er.; N. ustulatus, 
nebulosus, semipunctatus and obliquus=B. ustulatum, Dej., Er.; N. 
stictus may correspond with the lately described N. Dejeanii, Putz. ; 
N. fumigatus is Dejean’s Bembidium of the same name; N. ephip- 
pium= B. pallidipenne, Dej. (non Ill.) ; N. eastanopterus is a pale 
variety of B. assimile, Gyll., Dej., Er. | 
Lopha pecila= B. articulatum, Dej.; L. quadriguttata and quadri- 
maculata are Dejean’s species of the same names; L. pulchraisa 
bluish specimen of B. celere ; L. assimilis=B. Doris, Ill., Dej., Er. ; 
L. pusilla and hemorrhoidalis are also the same as B. Doris, ill. ; L. 
nigra=B,. Mannerheimii, Sablb., Dej.; L. pulicuria and minima=B. 
pusillum, Gyll., Dej.; L. nana is wanting in Stephens’s collection ; 
L. Doris and Spenciti=B. assimile, Gyll., Dej. 
Tachypus celer = Bemb. celere; T. acutus, Marsh., is an immature 
specimen of the same species; 7’. properans, chalceus and orichalcicus 
=B. velox, Er.; T. bipunctatus=B. bip., Dej., &c.; T. chlorophanus 
and striatus=B. erosum, Er. 
Bembidium impressum is quite distinct from B. impressum, Dej., 
being nothing but an ill-preserved specimen of B. flavipes. 
Notiophilus tibialis, Ste.=N. palustris, Er., whilst N. pe of 
the Stephensian collection belongs to N. biguttatus, Er. 
[As Dr. Schaum’s remarks on the British Water-beetles, ails 
form a part of his paper in the ‘ Entomologische Zeitung,’ have 
already appeared, in a more detailed form, in this country (see Zoo- 
logist, pp. 1887 and 1932), it has not been considered necessary to 
reproduce them here. } 
PsELAPHIDA AND SCYDMANIDA. 
Sceydmenus ruficornis, Denny, is nothing but the female of S. den- 
ticornis. I have compared two of the specimens mentioned by Denny 
himself. 
S. Wighami, Denny (also according to an original specimen which 
E. Doubleday communicated to me) is identical with S. angulatus, 
Kunze. The species could not be recognized from Denny’s imperfect 
figure. 
"5 punctipennis, Ste., is a true S, collaris. 
S. Dennii, Ste., as I had previously supposed, is the male of S. den- 
ticornis. Several species of this genus were incorrectly determined
