Tribe II. HALYINI Stal, 1854, 233. 



This tribe is represented in the Old World by numerous 

 genera, but only one is found in North America. This is the 

 Brochymena of Amyot and Serville, a typical American genus 

 containing a dozen or more closely related species, nine of 

 which occur in the eastern states. They are commonly known 

 as "tree bugs."

Large, broadly oval, subdepressed species having the head 

 porrect, its sides straight ; cheeks flattened or slightly concave, 

 equalling or surpassing tylus, the side margin of each usually

 a projecting tooth or spine ; antennae slender, longer than head 

 and thorax, inserted beneath cheeks some distance in front of 

 eyes; beak reaching or surpassing base of second ventral, its 

 second and third joints subequal, the fourth one-third shorter. 

 Pronotum subhexagonal, its front half narrower and on a lower 

 plane than hind one, its surface very uneven and side margins
