148 FAMILY V. — PENTATOMID,£. 



XIII. Neottiglossa Kirby, 1837, 276. 



Small, oblong-oval convex species having the head strongly 

 deflexed ; cheeks longer than tylus and usually meeting in 

 front of it ; antennae slender, scarcely reaching base of pro- 

 notum, the third joint shorter than second, the fourth and fifth 

 thicker and longer; beak usually reaching middle of hind coxae, 

 its second joint as long as third and fourth united; pronotum 

 with a more or less evident transverse median groove, the front 

 portion but slightly lower than the hind one, side margins 

 straight, humeri rounded, not prominent ; scutellum broad, 

 but little narrowed behind, its apex wider than and surpassing 

 that of corium ; membrane reaching tip of abdomen, hyaline, 

 its veins simple ; connexivum very narrowly or not at all ex- 

 posed ; osteole not or slightly prolonged as a wrinkle beyond 

 the opening, but without auricle or canal ; tibiae not or very 

 faintly sulcate above. Genital plate of male semi-circular, 

 almost perpendicular, its hind margin truncate. 



About 15 species are known, most of them palaearctic in dis- 

 tribution. Four of them occur in the United States, all in our 

 territory. They are found mostly on grasses and clover in open 

 fields and meadows.
