NEW BRITISH SPECIES, ETC., IN 1866. 107 



of imaginary species, and the insect was also again described 

 by him under another name. 



Bradycellus rufulus, Dej. 

 Mr. Crotch (loc. cit.) proposes to follow Dejean, who first 

 clearly separated this insect and its allies, in preference to 

 using Duftschmidt's ver'hascif as brought forward by Dr. 

 Schaum, since Duftschmidt probahli/ mixed more than one 

 species. Marsham's fulvus is not to stand, his description 

 being (certainly) valueless, and the name pre-occupied. Mr. 

 Crotch is inclined to link B. collaris with B. harpalinus ; 

 and, probably, with this insect also. 



Bembidium RiPARiUM, Payk., 1790; Oliv.; Schaum, Ins. 



Deutschl. i, 737, 63, B ; G. R. Crotch, Cat. Brit. 



Col. ed. 2. 

 Mr. Crotch (loc. cit.) gives this insect as a " sub-species " 

 of B. higuttatu7n, Fab. : it appears to be the largest form 

 of that insect, 2^ lin. long, and has the seventh stria of the 

 elytra indistinct. Bifjuttatum is retained for the smaller 

 form, like B. guttula, with distinct seventh stria. These se- 

 parations have long been made by Duval and Schaum. 

 B. ce7ieum, Germ., Mr. Crotch unites with those as a mere 

 coast form; and, following the "sub-species" scheme, con- 

 nects B, Mannerheimii with B. guttula, B. assimile with 

 B. Clarkiij B. pusillum with B. normannunij B, lampros 

 with B. velox, Er. (which he states to be rare in this country, 

 and distinguished by the presence of the seventh stria on 

 the elytra), B. tihiale with B. atro-cceruleum and B. adus- 

 tum with B. varium, 01. {udulatum, Dej.). As, however, 

 all these insects are numbered as species in Mr. Crotch's 

 Catalogue, it becomes rather difficult to know what exact 

 value he proposes to give to them.
