HARPOCERA, Curt. 
This curious genus, our British species of which is as 
large as a Calocoris, may be at once known by the form of 
its antenne; these in the ¢ have the second joint about 
as long as the first, bent and angularly produced at the 
apex on the under side, and the third joint bent, and much 
longer than the second; in the ? the second joint is more 
than twice as long as the first and simple, the third is bent 
and much longer than the second; rostrum only reaching to 
the anterior coxe; the male is narrower than the female, 
and its front tibie are very long and curved, the inter- 
mediate and posterior pairs slightly so, in the 9 the posterior 
pair, only, show a slight curvature ; all the pairs with black 
spots and spines.

the ? more than four times, as long as the anterior margin, 
sides sinuate ¢, rounded 2, base sinuate in both sexes,
