242 FAMILY VI. — COREID;£. 



Tribe VIII. COREINI Stal, 1867, 547. 



Oblong-oval or elongate species of small or medium size 

 having the head subquadrate or subtriangular, porrect, less 

 than half the length of pronotum, narrowed and produced a 

 little forward in front of bases of antennae; tylus equalling or 

 slightly surpassing cheeks and with them more or less de- 

 clivent or deflexed between the antenniferous tubercles, the 

 latter well separated, not prominent; antennae slender, joints 

 2 and 3 cylindrical, 4 shortest; beak slender, not reaching hind 

 coxae, joints 1, 2 and 4 subequal, 3 shorter; pronotum sub- 

 hexagonal, its margins usually entire ; legs slender, the femora 

 usually unarmed ; tibiae simple, cylindrical ; spiracles usually 

 nearly equally distant from the apical and hind margins of 

 the ventral segments. 



Stal (1867, 547) included under his Coreida (Coreini) 20 

 American genera and one has since been founded by Uhler. Of 

 these Van Duzee recognized 11 from the United States, and 

 also wrongfully included with them Chelinidea Uhler, separated 

 above. Of the 11, five are represented in the eastern states. 



KEY TO EASTERN GENERA OF COREINI. 



a. Hind femora armed beneath with several spines; body elongate; legs 

 very short, the hind femora not surpassing the fourth ventral. 



I. Namacus, p. 243. 

 aa. Hind femora unarmed; 4 - body -oblong or oblong-oval; legs longer, 

 the hind femora passing the fourth ventral. 

 b. Veins of the membrane very fine and numerous, everywhere ir- 

 regularly anastomosing; tylus elevated and compressed above the 

 cheeks to form a keel between the bases of antennae; length, 9 — 

 11mm. II. Marcus, p. 243. 



66. Veins of the membrane fewer, much coarser, simple or a little 

 forked ; tylus not elevated and compressed above the cheeks. 

 c. Beak almost reaching or surpassing middle coxa?, its first joint 

 extending beyond hind border of eyes; front side margins of 

 pronotum entire or nearly so. 

 d. Head very broad, subdepressed, the eyes projecting outward dis- 

 tinctly beyond apical angle of pronotum; ocelli separated by 

 a space nearly twice that between them and the eyes ; spiracles 

 placed nearer the side margins of ventrals than from either 

 the front or hind margins; smaller, not over 12 mm. 



III. Catorhintha, p. 244. 



dd. Head narrower and more convex, the eyes not or but slightly 



projected outward beyond apical angle of pronotum; ocelli 



separated by a space about equal to that between them and 



^Except rnrely in Anafta.
