228 FAMILY VI. — COREID^E. 



of markings of pronotum, with numerous synonyms. Known in 

 this country only from Florida, Texas and California. Uhler 

 (1876, 299) says that, "In the fresh full-colored varieties, the 

 bright orange bands of the pronotum contrast richly with the 

 vivid steel-blue of the ground color." 



Tribe IV. MICTINI Stal, 1867, 535. 



Coreids of medium or large size and usually broadly oval 

 form having the head short, broad, subquadrate, not produced 

 forward between the bases of antennae; beak short, stout, not 

 reaching middle coxae; tylus more or less compressed and de- 

 flexed between the antenniferous tubercles, the latter borne on 

 or forming the upper front portion of the cheeks, the space 

 between them rarely but little wider than the tubercles them- 

 selves ; pronotum with front side margins usually distinctly 

 toothed; femora, at least the hind ones, spined beneath. 



The tribe is represented in tropical America by 20 or more 

 genera, and in the United States by seven. Of these members 

 of four are recorded from the eastern states. 



KEY TO EASTERN GENERA OF MICTINI. 



a. Antenniferous tubercles without a spine on the outer side, the space 

 between them filled by the convexity of tylus ; head not tuberculate 

 behind the eyes. 

 b. Truncate hind margin of pronotum not wider than base of scu- 



tellum; hind femora of males not strongly swollen. 



c. Abdomen subrhomboidal, widely dilated opposite middle of elytra, 



the connexivum very broadly exposed. I. Mozena, p. 228. 



cc. Abdomen elongate-oval, but slightly widened opposite middle of 



elytra, the connexivum narrowly exposed. Capaneus. 42 



bb. Truncate hind margin of pronotum distinctly wider than base of 



scutellum; hind femora of males strongly swollen. 



II. Archimerus, p. 230. 

 act. Antenniferous tubercles spined on the outer side, the space between 

 them vacant; head with a distinct tubercle behind each eye. 



III. EUTHOCHTHA, p. 233. 



I. Mozena Amyot & Serville, 1843, 192. 



Large, broadly oval depressed species having the head less 

 than half the length of pronotum, subquadrate ; tylus a little 



'-While this genus is included in the key, the only species recorded from the 

 eastern states is the Lygoeus incubitor Fabr. (1794, 136). It was described from 

 "Carolina," was unknown to Stal (1870, 227) and is not at present represented in 

 any collection in the United States. It is not, therefore, considered farther in this 

 work. Two other species of the genus, described by Stal from Mexico, occur in the 

 southwestern states.
