SUBFAMILY IX. — PHYLINyE. 955 



front subvertical, tylus narrow, compressed, vertex feebly con- 

 vex, not carinate at base ; eyes large, coarsely facetted, con- 

 tiguous to pronotum, larger in male than female ; antennae 

 shorter than body, joint 2 as long as or longer than width of 

 base of pronotum ; beak reaching or surpassing middle coxae ; 

 pronotum trapezoidal, sides straight or nearly so, disk feebly 

 convex, declivent forward, hind margin truncate ; mesoscutum 

 narrowly exposed ; elytra entire, surpassing abdomen ; cuneus 

 feebly deflexed, its fracture weak. Twelve species have been 

 recorded from the eastern states. The genus, as treated, in- 

 cludes the two eastern species of Apocremnus Fieb., listed by 

 Van Duzee.
