Above obscure greenish brass. Head and thorax sometimes a 

 little coppery ; base of the palpi and three joints at the base of 

 the antennae testaceous red, the remainder brownish black. 

 Thorax subcordate, rather short, moderately rounded at the sides 

 and narrowed behind, posterior angles right angles, the base 

 depressed, and together with the two deep basal fovese punctured, 

 the dorsal furrow strongly impressed. Elytra oblong, rather 

 narrowest in front, sides somewhat parallel, disk flatter than in 

 the preceding species, strongly punctate-striated, the three or 

 four strise nearest the suture as usual deeper than the rest, but 

 the exterior ones also distinct and all of them carried to the apex, 

 the third interstice with the usual evident impressions, two tes- 

 taceous spots on each elytron, the one at the shoulder extending 

 from the outer margin almost, if not quite, to the suture, the 

 posterior one round and always rather the palest and most con- 

 spicuous; legs reddish testaceous, with the femora sometimes 

 rather obscure. Length 2^ lines. 



There is a permanent variety of this species, which I have 

 found in profusion in the Isle of Wight and elsewhere in the 

 south of England, presenting very constant characters. It is 

 more depressed, never narrower in front, the sides therefore 

 more parallel, and the colour is always much paler and the spots 

 larger, that before the apex round and very conspicuous, and the 

 anterior one occasionally expanding over the surface very con- 

 siderably; and it is to be remarked that this paler variety is found 

 only in the south, while the darker examples are confined to the 

 more northern and eastern districts : abundant on the banks of 

 the Tyne and Derwent, &c., as well as in Ireland and Scotland, 

 and occasionally near London : the pale variety all along our 

 southern coasts. 



17. B. testaceum : capite thoraceque viridi-aneis ; thorace an- 

 gustiore, subcordato, angulis posticis rectis, aut paululum 

 acutis ; elytris oblongis, subparallelis, punctato-striatis, 

 rufo-testaceis, sutura distincte fasciaque sinuata postica 

 obsoletissime virescentibus; antennis basi pedibusque rufo- 

 testaceis.
