STYGNUS, Feb. 
Closely allied to Acompus, but easily recognizable by the 
more finely punctured and the finely pubescent upper 
surface, and by the dull surface of the elytra, whose clavus 
has four series of punctures instead of only three as in 
Acompus ; anterior femora beneath with a series of fine 
hairs, or spine-like bristles. One species, viz. rusticus, is 
dimorphous, the undeveloped form being the common one ; 
the developed form is the Stethotropis incana, Fieb. We 
possess three out of the five recorded Huropean species ; 
pygmeus, Sablberg, which is closely allied to arenartus, 
but has a longer terminal joint to the antenne, and is 
smaller in size, may yet be added to our list.

S. rusticus, Fall. (incanus, Fieb. (macr.).—Black or 
brown, clothed with short adpressed pale hairs, dull, closely 
punctured, legs and antenn ferruginous, except the apical 
joint of the latter, which is black or brown. Head short, 
triangular ; eyes prominent, projecting beyond the pro- 
notum at its anterior angles; pronotum trapeziform, sides 
rounded in front and slightly sinuate behind the middle ; 
base rather deeply sinuate ; scutellum punctured like the 
‘pronotum ; elytra with the corium and clavus rather more
