femora behind and the intermediate and posterior ones, except 
their knees, black, the anterior tibia beneath and the inter- 
mediate ones with a litura at their apex beneath, and the posterior 
ones, excepting a ringe at their base, black; the tarsi yellow, 
with their apical joints rufo-piceous, the posterior ones with the 
basal joint, and the base of the second only, yellow, the rest 
piceous. 
The abdomen subclavate, subpubescent, black, and shining ; 
the apical segment flavo-testaceous . 
I am unacquainted with the 9.

Society of London. 
+; This insect, which is unique in the above collection, 
exactly resembles the Crab. elongatulus in the sculpture of 
the metathorax; but the difference of the colour of the 
legs and tubercles, and other minute distinctions, permit me 
I think to consider it more than a variety and specifically 
distinct, it being of the same sex as those I know of that 
species. It is very like the ¢ of Crossocerus varus of St. 
Fargeau, but wants the yellow on the prothorax and scu- 
tellum, and minor differences, which prevent my treating 
it as that insect.
