SUBFAMILY III. — ORTHOTYLIN^E. 845 



e. Form oblong-oval; membrane of nearly the same texture as 

 corium and with only one cell; base of vertex carinate. 



IV. Hyalochloria, p. 848. 

 ee. Form elongate, subparallel ; membrane differing in texture from 

 corium and with two cells; base of vertex not carinate, male, 

 very obtusely so, female. V. Diaphnidia, p. 849. 



dd. Eyes placed near hind margin of head, close to pronotal angles; 

 elytra rarely in great part hyaline. 

 /. First antennal with a black line on each side, these connected 

 beneath near apex; eyes, viewed from above, elongate, their 

 inner margins parallel ; color white or greenish, clothed with 

 rather long white pubescence. VI. Reuteria, p. 851. 



//. First antennal without black lines; eyes not so elongate, their 

 inner margins diverging. 

 g. Joints 1 and 2 of antennae strongly swollen, 2 fusiform; mem- 

 brane finely rugose; third and fourth antennals united only 

 half the length of second. VII. Heterotoma, p. 851. 



gg. Joint 2 of antennae linear; membrane not rugose; third and 

 fourth antennals united distinctly more than half as long as 

 second. 

 h. Head vertical, viewed from above not prolonged in front of 

 eyes; pronotum of male campanulate, sinuate at base, the 

 humeral angles prominent; female usually brachypterous, the 

 abdomen very broad. VIII. Mecomma, p. 852. 



hh. Head declivent, viewed from above prolonged before the front 

 margin of eyes; pronotum trapezoidal, humeral angles not 

 abruptly prominent; sexes similar. 

 i. Head strongly compressed apically; vertex declivent behind, 

 not margined at base, usually with a small pale spot each 

 side ; basal width of pronotum very little greater than width 

 of head. IX. Cyrtorhinus, p. 853. 



ii. Head not distinctly compressed apically; vertex usually mar- 

 gined at base, when black never with a pale spot each side; 

 base of pronotum distinctly wider than head. 

 j. Base of vertex carinate, sometimes obtusely so, the carina 

 never beset with bristly hairs; beak usually reaching hind 

 coxae; xyphus moderately sulcate, its sides V-shaped. 



X. Orthotylus, p. 854. 

 jj. Base of vertex not carinate, the basal margin beset with 

 bristly hairs and with an alutaceous glabrous spot adjoin- 

 ing the eye each side; beak not passing hind margin of 

 mesosternum; xyphus deeply excavated, its sides U-shaped. 



XL Noctuocoris. p. 865. 



I. Globiceps LePeletier & Serville, 1825, 326. 



Elongate, narrow, subparallel species (male) or suboval 

 (female), having the head wider across eyes than long, its 

 front vertical; beak reaching middle coxae; antenna? shorter
