TROPISTETHUS, [ieb. 
A genus with only one European representative, which 
is a very small species, in fact, the smallest of our Ly- 
geide. It may be known by the almost ecarimate pro- 
notal margins, and by having two longer spines on the 
anterior femora, followed by numerous small ones between 
them and the apex of the femora. Head with the antenni- 
ferous tubercles largely developed, blunt, eyes not touch- 
ing the anterior margin of the pronotum, rostrum reach- 
ing to the intermediate cox; pronotum subtrapeziform, 
anterior margin and base rather deeply sinuate, sides 
slightly so behind the middle, with a very obtuse carina 
only visible when examined laterally ; scutellum raised at 
the base ; elytra with the membrane often not reaching to 
the apex of the abdomen; anterior femora incrassated, 
bearing beneath two rather longer fine spines and numer- 
ous shorter ones ; tibiz without bristles.
