Capur nigrum, sub lente punctatum, Labrum Palpique flavo-ferruginea. Antenne 
flavo-ferruginez, medio saturatiores, subclavate, thoracis longitudine, seu illo 
pauló longiores ; articulis 4—6 obconico-cylindricis, reliquis sensim crassioribus 
turbinatis ; 8vo contiguis dimidio minori, extimo ovato. 
Truncus, Thorax transverso-sub-quadratus longitudine vix latior, lateribus rotun- 
datis (haud ad angulos posticos subrectis), posticé rectus sine ullä excisione. 
Coleoptra thorace vix latiora, sed plus dupló longiora, interdum apud apicem 
. Obsoletissimé striata, apice obtusiuscula. Pedes flavo-ferruginei femoribus anticis 
in utroque sexu similibus, apice vix attenuatis, 
Var. B. Picea tota, antennis pedibusque ferrugineis. 
Of this insect I have seen but two specimens, which chanced 
to be the sexes—the female in the cabinet of my kind friend 
Thomas Marsham, Esq. V.P.L.S., after whom I have named the 
species; the male in my own. The fore thighs of the latter are 
not incrassated at the apex, as in the males of the preceding spe- 
cies, and it is a shade or two lighter in colour than the female. 
This difference and the usual sexual distinctions in the tarsi 
 excepted, the sexes are precisely similar. |
