Gravelly banks of rivers and streams ; also damp sandy places near the coast ; local 

 but widely distributed ; rare in the London district; Tonbridb^e ; New Forest; banks 

 of Trent and Dove, Repton, Burton-on-Trent ; Hewdley ; Church Stretton ; Llan- 

 gollen ; Bridlino;ton, Yorkshire; Northuuiberhmd and Durbani ; and many other 

 localides. Scotland, abundant throughout tlie country; Ireland, near Dablin. 



A large variet}' 7 mm. in length occurs in Charnwood Forest, Leices- 

 tershire, which may perhaps be referred to the type form fa^riolatuin, 

 but in a large series so many gradations of form both of thorax and elytra 

 are to be observed that it is almost impossible to separate the varieties 

 satisfactorily ; it is very probable that D. atrocceruleum and B. tibiale 

 ought both to be considered varieties of the type, as they have been by 

 many authors, and not separate species. 



S. atrocaeruleum, Stcph. {fasciolatum var. B., Duv,). Very like 

 B. tibial:, but smaller and narrower and usually of a brighter blue colour ; 

 the thorax is more contracted behind, so that the anterior margin is con- 

 siderably broader than the posterior, and the hind angles are slightly 

 more projecting ; the elytra also are longer in proportion, and the striw 

 are usually more slender and less strongly punctured. L. 3|-4 mm. 



Widely distributed both in Euyjlaud and Scotland, and found under the same 

 circumstances and in the same localities as the preceding, of whiidi it is probably only 

 a variety; Ireland, near Belfast, and probably to be found in many other districts; 

 in its general appearance it is certainly very distinct. 



B. decorum, Panz. ]Morc elongate and flatter than any of the 

 following species of the group, and with more parallel-sided elytra ; blue 

 or bluish green, unicolorous ; antennae dark with the first joint and base 

 of the three following reddish yellow ; thorax cordiform, nearly as long 

 as broad, posterior angles right angles, somewhat prominent, dorsal furrow 

 strong, basal foveoi wide, rugosely punctured, base with no trace of a 

 loiigiuidinal fold near the posterior angles (which is evident in the suc- 

 ceeding species); elytra elongate, depressed, almost parallel-sided, with 

 strong punctured stria;, evanescent towards sides and apex ; legs red. 

 L. 5-13 mm. 



Gravelly places on the banks of rivers and streams; rare in the south of England, 

 and in the London district (G. C. (.hampion); very conunon in the Midlands and the 

 north (banks of Trent, Ouse, &c.); Scollaud, abundant; Ireland, near Belliist and 

 Dublin, and probably widely distributed. 



B. nitidulum, Marsh {hrunnipes, Sturm). Shining metallic gi-cen, 

 sometimes bluish ; antennae dark with the first joint and base of tho 

 three following (sometimes the first three entirely) red ; head rather 

 short, eyes somewhat prominent; thorax .short, transverse, cordiform, 

 posterior angles sharp riglit angles, dorsal furrow distinct, Tjasal foveic 

 deep and large, base coarsely punctured ; elytra oval, rather convex, with 

 very strong coarsely punctured slrite on disc, which become much feebler 

 lowards sides and apex; legs testaceous, femora more or less pitchy. 

 L. 4-5 mm. 



Damp sandy places in woods or open places and on the coast, common and widely
