Entirely black: head pubescent, deeply punctured, more

tudinally striated, and enclosed by a smooth and shiny limbus, 
not defined on its posterior margin, the sides and posterior por- 
tion of the metathorax punctured, the punctures decreasing 
gradually upwards towards the limbus, at the centre of the pos- 
terior margin whereof there is a deep fossulet extending towards 
the apex of the metathorax, on the sides of which and on the 
collar are long griseous hairs ; the wings slightly coloured, the 
nervures piceous, and sometimes a coloured cloud on the disk; 
the anterior tarsi very slightly ciliated, and a very few slight
