GASTRODES, Westw. 
A genus at once known by its very wide and very flat 
shape; the head is small; the eyes and ocelli almost touch 
the pronotum ; the rostrum reaches beyond the posterior 
coxée ; the pronotum is flat, with narrowly foliaceous sides, 
much widened posteriorly ; the scutellum is equilateral ; 
the elytra are much widened from the base to about their 
centre; the membrane is entire; the meso- and metasternum 
are very strongly furrowed ; the anterior femora very much 
incrassated, finely serrated beneath, with a strong subapical 
tooth followed by several small ones outwardly ; anterior 
tibiz much bent at the base; basal joint of the tarsi 
subequal to the other two taken together. 
We have both the European species in this country, 
They occur on Conifers.
