This insect is of an obscure bronze colour and rather smaller 

 than biguttatum. Head narrower and more convex, the frontal 

 furrows less deeply impressed and the longitudinal space between 

 them broader, smooth and shining, palpi and antennae obscurely 

 black, the basal joint of the latter sometimes pitchy, all the joints 

 more robust than in biguttatum. Thorax decidedly shorter and 

 more transverse, the lateral margins more reflexed and elevated 

 at the posterior angles, which are consequently more evident, the 

 base being emarginate below them, the dorsal furrow fine and 

 met in front by a distinct depression, the disk being also faintly 

 wrinkled, but not rugose at the base, which has on each side a 

 narrow deep oblique fovea. Elytra oblong-ovate, not wide in 

 front, as in the allied species, but somewhat narrowed at the 

 angles which are more rounded off, the sides being likewise more 

 rounded, the disk more finely punctate-striated and the punctured 

 striae less effaced towards the apex ; the underside of the body 

 and legs bronzed black. In some examples which I possess, 

 possibly offering less degrees of maturity, the elytra are brownish 

 black and there are indistinct traces of a pale spot behind, with 

 the apex also slightly rusty, as well as the legs and basal joint of 

 the antennas, but these examples have still the same short thorax 

 and finely punctate striae of the elytra which distinguish the 

 species. 



This insect is found upon the coast ; very abundantly in the 

 north of England ; on the shores of the H umber ; and near Brid- 

 port, Dorset, &c. Also in Ireland. 



9. B. guttula : nigro-subcmeum ; thorace brevi transverso, angulis 



posticis obtusis; elytris oblongo-ovatis, punctato-striatis, 

 macula apicali antennarum basi pedibusque rufo-testaceis.
