 middle of pronotum; head, viewed from the side, distinctly sur- 

 passing front line of eyes; pseudarolia prominent (pi. X, figs. 18 

 —20). 

 b. Pronotal disk distinctly transversely sulcate just behind calli; eyes 

 large, vertical; head narrowed to form a distinct neck behind 

 eyes. II. Dicyphus, p. 907. 



hl>. Pronotal disk not transversely sulcate behind the calli. 



c. Eyes large and vertical, the head space behind them short, not 



equal to half the width of an eye. III. Cyrtopeltis, p. 911. 



re. Eyes small, oblique placed at midde of head, the space behind them

Elongate-oval, shining species having the head strongly nar- 

 rowed behind eyes to form a distinct neck, its front vertical, 

 vertex wider than the lateral width of an eye ; pronotum sub- 

 campanulate, sides strongly converging from base to apex, 

 hind portion convex with basal angles subnodulose ; elytra nar- 

 rowly oval, surpassing abdomen by half the length of mem- 

 brane ; corium, embolium and cuneus of nearly the same texture 

 as membrane ; cuneus but slightly deflexed, membrane one- 

 celled. One of the two known species occurs in our territory.
