 near Bristol. " Common (near Swansea), principally in woods." — 

 L. W. Dillwyn, Esq.

Black : thorax glossy, immaculate : elytra dull-fuscous, linear, rather elongate, 

 immaculate at the apex : body beneath and femora black : tibiae and base of 

 the antennae dilute fuscous, or slightly pale. 



The concolorous apex of the elytra, black thorax, and dark legs, well characterize 

 this insect.

 " Frequent (near Swansea).'" — L. W. Dillwyn, Esq. 



b. With the thorax transverse, very short. 

 Sp. 19. brevicollis. Niger, elytris pedibusque fuscis. (Long. corp. § — 1^ lin.)
