SUBFAMILY I. — ARADINiE. 295 



margins broadly rounded, but slightly reflexed, their edges finely irreg- 

 ularly dentate; disk with median carinae entire, lateral ones shortened 

 and curving inward. Seutellum, subpentagonal, its sides parallel to 

 middle, then converging to apex; disk feebly transversely elevated at 

 base. Basal expansion of corium long, narrow, dentate. Connexivum 

 broadly exposed, its margin crenate. Male with fifth ventral slightly 

 shorter than sixth, genital segment short, strongly convex, elytra reach- 

 ing nearly to tip of abdomen ; female, elytra reaching to base of dorsal 

 genital, the hind margin of latter slightly emarginate. Length, 5.5 — 7 

 mm. (Fig. 64; PI. I, fig. 11). 



Frequent throughout Indiana, Feb. 15 — July 10. Staten and 

 Long Islands, N. Y., May — June (Davis) . Lives and hibernates 

 beneath bark of red and black oaks. Ranges from Quebec and 

 New England west to Nebraska and North Dakota, and south 

 and southwest to Florida, Oklahoma and Texas. Parshley 

 (1921, 41) mentions it from Jacksonville, Fla., this being the 

 only record for that State. He also describes a color variety, 

 insignis, from Texas, North Carolina, Michigan, etc. It has the 

 "narrow postero-lateral margins of pronotum, apex of seu- 

 tellum and most of corium yellowish ; abdomen reddish-brown 

 above."

Oblong-oval; head, pronotum and seutellum thinly granulated. Dark 

 brown, variegated with dull yellow; first antennal joint and beak pale; 

 apex of seutellum, veins, inner part of basal expansion and more or 

 less of disk of corium dull yellow; hind margins of connexival segments 

 and wide inner margin of genital segments yellowish; legs pale, the 

 tibiae and tarsi often with a broad dusky ring. Head as wide as long; 

 tylus narrow, compressed, tapering but obtuse; antenniferous spines 

 stout, divergent; impressions of vertex deep, oblong; antennae stout, 

 cylindrical, as long as head and pronotum united, second joint one- 

 third longer than third, the latter twice as long as fourth; beak reach- 

 ing front coxae. Pronotum with side margins thickened, broadly re- 

 flexed, their edges granulate; disk with median carinae entire, the others 

 confined to basal half. Seutellum elongate-triangular, longer than pro- 

 notum, sides straight, converging from the base, moderately elevated. 

 Basal expansion of corium prominent, semicircular. Connexivum 

 broadly exposed, its margins almost entire. Male with fifth ventral 

 shorter than sixth, genital segment short, very convex, its lobes long, 

 elytra reaching their middle; female with abdomen broader, hind margin 

 of dorsal genital straight, elytra reaching base or middle of genital lobes. 

 Length, 6—6.7 mm. (PL I, fig. 13).
