anteniiK, li.i,^hter palpi, broader and flatter elytra, slightly broader and 

 ilatter thorax, and generally entirely pale legs, the femora being some- 

 times a little pitchy in the middle, instead of always entirely pitchy. 



Local ; banks of rivers aud streams near Dumfries ; also in the Tweed, Forth, 

 and Moray districts ; Dr. Sharp considers that in all probability this is the insect 

 described by Stephens as Peryphus marifimus, |takea by Mr. Rudd ou the banks of 

 the Tees; near Lanercost, Cumberland (Bold). 



B. littorale, 01. {Andrece, Er., listulatum, L. (H. E. W.) ). Head 



and thorax bronze green, elytra obscure bronze with two orange testaceous 

 })atches on each, separated by a broad dark space ; antemue brownish 

 with the three hrst joints and base of the two following reddish testa- 

 ceous ; thorax distinctly transverse, with the sides strongly rounded in 

 front and contracted behind, posterior angles sharp riglit angles, base 

 ]ilainly punctured in the middle, with a large deep punctured fovea ou 

 each side, dorsal furrow distinct ; elytra long o\'al, rather convex, rounded 

 at sides, with deeply impressed punctured striae, becoming evanescent 

 towards sides and apex ; legs entirely pale testaceous. L. 5-5| mm. 

 Very common aud widely distributed throughout the kingdom. 



B. fluviatile, Dej. More elongate and convex than the preceding, and 

 with the orange markings on elytra brighter, especially when the insect 

 is alive ; head narrower, antenna3 longer ; thorax much narrower and 

 longer (at least as long as broad), with the sides less rounded in front, 

 dorsal furrow finer, basal fovetB smaller ; elytra narrower aud longer, 

 more convex, the inner stria' not quite so strong, but the outer ones 

 almost as strong as the inner, seventh stria usuall}' distinct ; legs testa- 

 ceous : easily distinguisheil from the preceding, which is the only 

 species it is likely to be mistaken for, by its long narrow thorax. L. 

 5|-6 mm. 



Very local ; apparently only found in the midland and mid-western districts of 

 England ; banks of Wye near Ross ; Bewdley ; Draycolt, near Derby ; banks of 

 Trent and Dove near Reptou aud Burton-ou-Trent ; banks of Trent near Newark : 

 it burrows in sandy places, and conceals itself in crevices in the clayey banks of 

 streams ; I have ol)taiiied it and many othei- Bemhidia by dashing the water up 

 ag;iiiist the hanks, when tlie beetles rusli out apparently under the ideu that w, 

 lliiod is rising; it apjiears to be a local aud somewhat rare species ou the Cou- 

 tiuent.
