Vagus in refpe&t to fize, and is of a deep black 
prune refembling velvet. The antenne are of a 
right yellow, and nearly aslong’as the body. ‘ihe 
elytra are adorned with high flame coloured croifs 
bars, which are formed by a down of a moft refulgent 
golden yellow. Viewed through the microfcope, it 
appears like velvet inlaid with topazes; and, when 
aliifted with the folar rays, nothing can excel its in- 
gaity of {fplendor. This moft wonderful infect for 
eauty is the poor tenant of a decayed tree, on which 
it may be frequently found, efpecially on an alder.

gated beauties. Many are found upon the wild ele- 
campane, growing on the fide of pends.
