Vol. \'I] van DUZEE— SPECIES OF ORTHOTYLUS 105 



Group II (Subgenus Orthotylus ?) 

 14. Orthotylus ovatus, new species. 



Form nearly of Lygus apicalis. Ovate, broader than the 

 typical forms of this genus ; green, nearly uniform, clothed with 

 sparse black deciduous hairs and minute white pubescence; 

 membrane infuscated. Length 4^mm. to tip of membrane. 



Head broad, convex; vertex flattened, transversely de- 

 pressed before the prominent basal carina. Front unusually 

 convex, polished ; clypeus small and but little prominent. Eyes 

 large, about one-half the width of the vertex; viewed from the 

 side ovate, a little oblique, reaching below the middle of the 

 sides of the head. Antennae normal, the first joint shorter 

 than the head. Pronotum transverse, more convex than usual 

 in this genus; anterior angles well rounded; callosities large, 

 moderately elevated. Elytra short and broad, the costa regu- 

 larly but not greatly arcuated, the apex of the abdomen pass- 

 ing the middle of the cuneus in the male, attaining its apex in 

 the female. Rostrum long, reaching about to the base of the 

 venter. 



Dextral hook of the male genitalia long, widened to the 

 truncated apex, long triangular, with a very sharp spur at the 

 superior apical angle, this spur but little shorter than the width 

 of the piece at that place; sinistral hook broad, ligulate, its 

 rounded apex attaining the sinistral margin. 



Color pale green, becoming more or less yellowish. Upper 

 surface clothed with short black hairs and a minute white 

 pubescence, easily denuded. Antennae a little infuscated. Mem- 

 brane quite strongly infuscated, usually pale at base, the nerv- 

 ures pale. Tibial bristles pale. Tip of the last tarsal joint 

 black. In faded specimens the thickened costal nervure is the 

 last to lose its green color. 



Described from numerous individuals beaten from juniper 

 trees along Glen Alpine Creek near Fallen Leaf Lake, Calif., 

 during July. 



This species is very close to Oncotylus ptiberus Uhler, but 

 after a careful examination of the types I am unable to con- 

 sider them the same.
