Dec, 1908.] Aradidae of Ohio. 39 



Color brown. First joint, except at the base, tip of scntelluni, marj^in of 

 abdominal segments and legs, 3ello\v. Terguni and disk of venter suffused 

 with rufous. 



Tliis species has been collected at Westerville by Mr. Jas. G. 

 Sanders, and at Cincinnati by Mr. Clias. Dur}-. It is recorded 

 also for Canada and Pennsylvania by Bergroth, and this attthor 

 stiggests that this species has been mistaken for oniatus and so 

 recorded in some earlier papers. 



It is a little more slender than that species, the general color 

 more distinctly brown, base of elytra less dilated, and the depres- 

 sions on the pronotum not polished. 



Aradus duryi n. sp. 



Broad, sides stibparallel. Brown with ochery markings. An- 

 tennae, joints 2 and 3 nearly equal. Length, female, g mm. 

 Width of abdomen, 4 mm. 



Head with anterior process much swollen, rounded at apex. Antennae 

 cylindric, joints of nearly equal diameter, first joint short, barely passing 

 lateral spine and much short of anterior process ; two and three almost 

 equal, one side two is slightly longer than three, on the other the reverse. 

 Beak extends to hind border of prosternum. Prothoi-ax broad, lateral angles 

 rounded, anteriorly narrowed; margin reflected, disk with four elevated 

 ridges, the inner ones approximate on anterior half, the outer ones broken 

 before the middle but continued to anterior margin. The carinaeare coarsely 

 granulate, the intercarinal spaces smooth but not polished. 



Scutellnm elongate triangular, margins raised and a median carina on 

 basal half, the margin at base and central carina granulate. Elytra with 

 basal fourth strongly dilated, membrane broad, widening to broadly round- 

 ing apex, which reaches nearly half wa}- upon the genital lobes. Abdomen 

 oval, broadly rounded behind, the sides subparallel ; genital lobes long, sep- 

 arate, divergent, obliquely subtruncate, the inner angles rounded. Fifth 

 ventral segment as long at margin as on median line, excavated, truncate on 

 median section, sixth segment at middle about one and one-half times longer 

 than fifth, slightly convex and medially notched. Seventh segment half as 

 long as sixth, notched on middle, terminal segment short, subangulate. 



Color, ashy brown, with lighter areas on base of wings and veins of 

 corium, and darker fuscous marks and veins on membrane. Antennae yel- 

 lowish brown, lightest at base, and terminal joint nearly black. The con- 

 nexiva are brown with posterior border yellowish, and the inner margin of 

 genital lobes of the same color. Beneath rather deeply infuscated, with 

 reddish yellow diffuse spots on the abdomen. The legs yellow with wide 

 fuscous annulations on femur and tibiae, and black tarsal claws. 



Described from one specimen, female, from Mr. Chas. Diir}-, 

 collected at Cincinnati, May 2, 1902.
