38 Dr. Schaum on the British Geodephaga. 



belong to the preceding si:)ecies, 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. rvpestre, Dej. ; P. littoralis 

 is B. rupestre, Dej. ; P. lunalus and iistus 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. 7iitidulus, 

 Marsh., is P. rujipes, 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. ; A''. 

 stictus may correspond with the lately described N. Dejeanii, Putz. ; 

 N.fumigatvs is Dejean's Bembidium of the same name; N. ephip- 

 jnui}i=^B. pallidipenne, Dej. (non 111.) ; A'^. castanopterus is a pale 

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



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

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

 bluish specimen oi B. celere ; L. assimilis^B. Doris, 111., Dej., Er. ; 

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

 nigru=rB. Mamm-heimii, Sahib., Dej. ; L. pulicaria and 7ninima=:B. 

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

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



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

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

 = B. velox, Er. ; T. bipunctatus:=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. = N. 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.] 



PsELAPHIDyE AND ScYDM^NID^. 



Scydmanus ?-uJicorms, 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, coUaris. 



S.Dennii, Ste., as I had previously supposed, is the male of S. den- 

 ticornis. Several species of this genus were incorrectly determined
