SUBFAMILY II. — COREIN^. 235 



KEY TO EASTERN GENERA OP MENENOTINI. 



a. Veins of membrane distinctly and irregularly anastomosing; prono- 

 tum with disk subdepressed, the humeri prominent and reflexed or 

 projected upward; abdomen very widely inflated, the body widest 

 behind the middle. I. Corecoris, p. 235. 



cm. Veins of membrane forked, not anastomosing; pronotum with disk 

 convex, the humeri not prominent or reflexed ; abdomen much less 

 inflated, the body elongate-oval. II. Sephina, p. 236. 



I. Corecoris Hahn, 1834, 14. 



Large, broadly oval depressed species, having the body 

 widest behind the middle; antennse less than half the length 

 of body, the basal joint curved, fourth not longer than third ; 

 bucculae very wide, their margins overlapping above basal joint 

 of beak; pronotum with disk uneven, humeri prominent, 

 rounded, prolonged outward and a little upward, front side 

 margins sinuate, their edge uneven but not dentate, posterior 

 side margins rounded into the subtruncate base; abdomen 

 widely dilated with sides broadly rounded and reflexed ; elytra 

 much narrower than abdomen ; membrane reaching the tip 

 of the latter ; metasternal pleura with hind margin broadly 

 rounded. Other characters as under tribal heading. 



About a dozen nominal species are known, all from tropical 

 America, two of which are recorded from the United States 

 and our territory. They have in the past been mostly recorded 

 under the generic name Spartocera Lap. 



KEY TO EASTERN SPECIES OP CORECORIS. 



a. Antenna? more slender, reaching behind base of pronotum, the first 

 joint distinctly longer than head; joints 2 — 4 subequal. 



169. FUSCUS. 



act. Antennse shorter, more swollen, scarcely reaching base of pronotum, 



the first joint but little longer than head; joints 2 and 3 subequal, 



4 one-third shorter. 170. diffusus. 



169 (277). Corecoris fuscus (Thunberg), 1783, 44. 



Broadly oval, depressed above, subconvex beneath, widest behind the 

 middle of abdomen. Above dull clay-yellow or brownish-yellow; antennae 

 black or fuscous; pronotum with apex and front side margins fuscous, 

 disk with two rather wide black lines converging and uniting in front; 

 base of scutellum often blackish ; connexivum alternated with black and 

 reddish yellow, in old specimens often vaguely so; under surface black 

 mottled with reddish-yellow; legs blackish, the coxae and knees reddish- 

 yellow. Structural characters as in key and under generic heading.
