PICROMERUS, Am. 8S. 
A genus easily distinguished by the spine-like posterior 
angles of the pronotum, together with the dentate anterior 
femora ; the anterior tibize also have a small spine behind, 
just beyond the middle. There are several European 
species, but we have only one in this country. 
P. bidens, Zinn.—Bronzy-brown, deeply punctured with 
black, some of the interstices reddish; antenne and legs 
red, pronotal spines black. Head bronzy-brown, central 
lobe reaching the front margin ; pronotum with its lateral 
margins narrowly red and rugose, diverging in nearly 
straight lines to near the middle, when they diverge more 
rapidly and form two large spine-like angles; base pro- 
duced, its scutellar angles acute, disc strongly punctured ; 
scutellum and elytra strongly punctured, the apex of the 
former and two small callosities at its basal angles red ;

There is only one European species of this genus, which 
is easily characterized by the lobately produced posterior 
angles of the pronotum and the spinose process of the
