38 Dr. Schaum on the British Geodephaga. 



belong to the preceding species, one to B. conc'mnum of Putzeys, and 

 the fourth to B. rupestre, Dej. ; B. tetraspilotus is wanting in Ste- 

 phens's collection. Two 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 111.) ; A^. castanopterus is a pale 

 variety of B. assimile, Gyll., Dej., Er. 



Lopha poecila=B. articulatum, Dej.; L. quadriguttata and quadri- 

 maculata are Dejean's species of the same names ; L. pulchra is a 

 bluish specimen of 5. celere ; L. assimilis=B. Doris, 111., Dej., Er. ; 

 L. pusilla and hcemorrhoidalis are also the same as B. Doris, 111. ; L. 

 tiigra~B. Mannerheimii, Sahib., Dej. ; L. pulicaria and mimma=B. 

 pusillum, Gyll., Dej. ; L. nana is wanting in Stephens's collection; 

 L. Doris and Spencii=B. assimile, Gyll., Dej. 



Tachypus celer = Bemb. celere; T. acutus. Marsh., is an immature 

 specimen of the same species ; T. properans, chalceus and orichalcicus 

 = B. velox, Er. ; T. bipunctaius=B. bip., Dej., &c. ; T. chlorophanus 

 and striatus=:B. cerosum, Er. 



Bembidium impressum is quite distinct from B. impressum, Dej., 

 being nothing but an ill-preserved specimen of B. flavipes. 



Notiophilus tibialis, Ste.=iV. palustris, Er., whilst N. palustris of 

 the Stephensian collection belongs to N. biguttatus, Er. 



[As Dr. Schaum's remarks on the British Water-beetles, which 

 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.] 



PSELAPHIDJE AND ScYDM^NID^. 



Scydmcenus 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. 



S . 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
