SUBFAMILY II. — COREIIsLE. 215 



thirds the length of second, fourth nearly as long as first. Pronotum as 

 in key, the basal portion across the humeri three times or more as wide 

 as apex; front portion nearly perpendicular, sides from humeri to apex 

 nearly straight, armed with eight or ten blunt teeth; disk with two 

 small rounded glabrous nodules at middle of apical third and a few 

 widely scattered smaller ones on basal half; humeri obtusely rounded, 

 their hind margin with a few teeth. Connexivum narrowly exposed. 

 Femora long, slender, the hind ones not greatly thickened, all armed 

 beneath on apical half with 4 to 8 teeth. Hind tibia? with outer dilation 

 widest on basal third, then abruptly angularly narrowed and of equal 

 width almost to apex ; inner dilation very narrow basally, male, slightly 

 wider, female, obsolete beyond the angulation of outer one, the inner 

 margin finely toothed from there to apex. Other structural characters as 

 in generic description. Length, 28 — 34 mm.; width, 11 — 12 mm. 



Utopia, Lake Okeechobee and Dunedin, Fla., scarce, Dec. 21 

 —March 4 (W.S.B). Raleigh, N. Car., May 2 (Brimley) . Re- 

 corded also from Chokoloskee, Fla., by Barber, and "Florida" 

 by Uhler (1876, 297). Say's types were from Georgia and 

 Louisiana and its known range extends from North Carolina 

 and Florida, across these states to Texas, Arizona and Central 

 America. My specimens were taken while beating the foliage 

 of red bay, Persea borbonia L., along the margins of wet ham- 

 mocks. Individuals of this and the next species are the largest 

 of our Coreids and among the largest of our eastern terrestrial 

 Heteroptera.

Elongate-oval, very robust, large for the genus. Dark chestnut or 

 fuscous-brown, thickly clothed above and beneath with fine appressed 

 yellowish hairs; membrane blackish-brown; tip of scutellum and in- 

 cisures of connexivum greenish-yellow; legs fuscous-brown, the front 

 and middle tibiae and all the tarsi paler. Head oblong, narrow, convex; 

 antenna? with basal joint stout, curved, nearly twice as long as head; 

 second about one-fourth longer than third, fourth slender, a little shorter 

 than first. Pronotum subhexagonal, with basal portion two and one-half 

 times as wide as apex; humeri obtuse, sides thence to apex straight, 

 armed with very small blunt teeth; disk with basal two-thirds convex 

 and bearing numerous small rounded, widely scattered tubercles. Con- 

 nexivum broadly exposed. Femora all rather stout, hind ones of male 

 extremely so, curved, armed beneath with two rows of short tubercles or 

 teeth, the median one of outer row long, curved, acute; hind femora of 

 female more slender, the teeth on apical half of outer row regu'ar and 

 longer than those of male; the sides and upper surface of these femora 

 in both sexes each with two rows of small tubercles. Hind tibia? with 

 outer dilation widest at base, in male gradually and evenly narrowed to 

 apex; in female abruptly narrowed at basal two-fifths and again at
