a. Membrane not pilose above and beneath. 

 6. Antennae long and slender, much longer than body; head short, 

 vertical ; vertex with a deep longitudinal impression ; sides of 

 pronotum not margined. I. Cylapus, p. 877. 



66. Antennae not longer than the body; head declivent; vertex without 

 a median impression; sides of pronotum margined, at least on 

 basal half. 

 c. Form elongate ; costal margins subparallel ; sides of pronotum con- 

 cavely arcuate; tarsi, as in other Mirids, 3-jointed. 



II. Fulvius, p. 878. 



cc. Form broadly oval; costal margins strongly curved; sides of 



pronotum not concavely arcuate; tarsi abnormal, only 2-jointed. 



III. Peritropis, p. 880.

IV. BOTHYNOTUS, p. 881. 



I. Cylapus Say, 1832, 26; I, 347. 



In addition to characters above given, this genus has the 

 eyes very large, protuberant, oblique ; antennae inserted above 

 the base of tylus by a distance equal to length of tylus, their 

 basal joint thickened, fusiform, the others filiform ; pronotum 

 with collar very narrow, calli short, not reaching the middle 

 of disk ; basal joint of tarsi as long as the others united. One 

 species occurs in our territory. 



969 (1090). Cylapus tenuicornis Say, 1832, 26; I, 347. 



Elongate-oval. Dark brown, subopaque; lower front of head, a spot 

 behind apical angles and median carina on basal half of pronotum, a spot 

 each side of base and tip of scutellum, an oblique submarginal ray near 

 middle of corium, apex of embolium and narrow inner margin of cuneus, 

 pale yellow; membrane dusky translucent, a bar across middle and apex 

 of cells paler, base of cells and veins darker; legs pale brown, apical 

 half of tibia? with one, of femora with two pale rings; gula, prosternum 

 and osteolar duct pale yellow; remainder of under surface dark chestnut 

 brown, shining, the ventrals thinly clothed with yellowish hairs. Joint 

 1 of antennae dark brown, paler at base, visibly curved, as long as width 

 of head across eyes ; 2 very slender, pale brown, extreme tip yellow, three 

 times as long as 1 ; 3 and 4 more slender, pale to dark brown, 3 slightly 

 longer than 2, 4 one-half the length of 3. Pronotum with calli prominent, 

 minutely punctate, separated by a narrow deep groove; disk behind them 

 short, wide, subdepressed, densely punctate and with a low median carina. 

 Scutellum, clavus and corium finely and densely punctate. Length,
