SUBFAMILY VII. — DER^OCORIN^E. 887 



II. Diplozona Van Duzee, 1915, 112. 



Short, oval, subglabrous, strongly punctate species having 

 the head nearly horizontal, slightly exserted ; vertex as in a 

 of generic key, without a basal carina; eyes large, prominent, 

 widely separated; beak reaching hind coxae; pronotum trape- 

 zoidal, sides feebly sinuate, narrowly margined, collar con- 

 spicuous, disk behind calli convex, strongly declivent, hind 

 angles obtusely rounded, basal margin broadly curved ; elytra 

 entire, cuneus feebly deflexed, membrane 2-celled, surpassing 

 abdomen by half its length. One species is known. 



982 (1055). Diplozona collaris Van Duzee, 1915, 114. 



Dull brownish-yellow, glabrous or nearly so; vertex with a vague 

 fuscous blotch enclosing a median pale spot; apical three-fourths of pro- 

 notum fuscous, with median line and a spot each side pale; collar and 

 basal fourth of pronotum dull yellow; scutellum blackish, its basal angles 

 and a short median apical stripe pale; clavus and apical half of corium 

 more or less clouded with fuscous ; embolium pale yellow, its outer edge 

 with minute fuscous punctures; cuneus hyaline, its tip and that of 

 embolium reddish-brown; membrane with apical third dusky, remainder 

 hyaline, veins darker; legs pale yellow, hind ones with apical third of 

 femora and two rings on tibia? and their tips, reddish-brown; under 

 surface dull yellow, a stripe on sides and genital plates darker. An- 

 tennae stout, half the length of body, joint 1 piceous-brown, as long as 

 width of body, 2 dull yellow, the clavate apex reddish; 3 and 4 fuscous- 

 brown, fusiform, their bases very narrow. Entire upper surface except 

 head and membrane, rather thickly, coarsely and evenly punctate. 

 Length, 4 — 5 mm. 



Dunedin, Fla., Oct. 25 — April 23; taken both on Hog Island 

 and mainland by beating foliage of buttonwood, Conocarpus 

 erecta L., and sweeping herbage along the bay front; also at 

 porch light. Described from Punta Gorda and Estero, Fla., and 

 not recorded elsewhere. Easily known from all other mem- 

 bers of the subfamily by the peculiar structure of the antennae. 



III. Eurychilopterella Reuter, 1909, 59. 



Oblong-oval, convex, punctate species having the head por- 

 rect, front feebly declivent, eyes not contiguous with pronotum, 

 vertex with base margined; antennae with joint 1 not reaching 

 tip of tylus, 2 as in key, 3 and 4 united much shorter than 2; 

 pronotum trapezoidal, calli rather large, covering the apical 

 third, disk behind them convex, declivent, sides straight ; scu- 

 tellum subequal in length to commissure, convex; elytra en- 

 tire, surpassing tip of abdomen, cuneus nearly horizontal ; legs 

 short. One species is known.
