behind the centre of the vertex, an impressed longitudinal lire 
extending from the anterior one to the face; the forehead, 
temples, and cheeks covered with a long pubescence ; the face 
canaliculated, smooth, and shining; the antenne black, fimbri- 
ated beneath, with a stripe at the sides of the scape yellow; the 
inner orbits of the eyes, and the clypeus (which is produced in 
front), covered with a dense silvery pubescence; the mandibles 
black. 
The thorax black, shining, delicately punctured; the collar 
and dorsolum covered with a long black pubescence ; the meta- 
thorax with a subcordiferm smooth and shining space at its base, 
which is divided from the posterior portion of the metathorax 
by a short consute transverse incisure, and it has down its centre 
a longitudinal deep incisure which beyond the transverse one 
dilates into a fossulet, at the sides of which it is smooth and 
shining ; the tegule piceous; the wings darkish, their nervures 
piceous; the legs black, the anterior tibize fulvous within, the 
intermediate femora with a fuscous stripe in front and behind, 
the tarsi piceous ; the anterior tibize and tarsi densely fimbriated 
on the exterior. 
The abdomen elongato-ovate, black, subpubescent, and shin-

of the metathorax it in some degrees resembles the C. leu-

but in that insect the subcordiform space is not so distinctly 
defined as in this. It would be a Crossocerus of St. Far-
