SUBFAMILY I. — ARADIN^E. 315 



broader than long, distinctly longer than pronotum; tylus thick, sub- 

 depressed, apex rounded; antenniferous spines stout, strongly divergent; 

 impressions of vertex, shallow, ill defined; antenna? short, stout, but 

 slightly longer than head, second joint one-half longer than third, the 

 latter subequal to fourth ; beak reaching mesosternum. Pronotum feebly 

 convex, side margins moderately flattened, not reflexed, their edges very 

 finely dentate; carina? evident but faint, confined to basal half. Scu- 

 tellum triangular, sides scarcely elevated, apex subacute. Abdomen 

 broadly oval, its margins almost entire. Male macropterous, elytra 

 strongly narrowed at middle, enlarged at apex, reaching base of genital 

 lobes, fifth ventral half the length of sixth, gen- 

 ital segment large, strongly convex. Female di- 

 morphic, in macropterous form, the elytra broad, 

 covering most of disk of abdomen and reaching 

 base of dorsal genital, in brachypterous form 

 but slightly longer than scutellum, membrane 

 absent, costal margin broadly rounded. Length. 

 3—5 mm. (Fig. 65; PI. Ill, fig. 55). 



Dunedin, Fla., Dec. 17— Jan. 31 {W.S. 

 B.). Wilmington and Long Island, N. Y. ; 

 Lakehurst, N. J. ; Southport, N. Car. ; Ra- 

 bun Co., Ga., April — July {Davis). Ranges 

 from Massachusetts west to Nebraska and 

 southwest to Florida, Texas and Cali- 

 fornia. Also occurs generally in the Palsearctic Region. The 

 Dunedin record is the first one for Florida, two brachypterous 

 females having been beaten from pine on the dates mentioned. 

 Parshley (1921, 96) states that it is usually taken by beating 

 pine branches rather than by searching under sheets of dead 

 bark. He quotes Kiritshenko 4s who says that : "In the district of 

 Lomja the damage done by A. cinnamomeus is appreciable, con- 

 sisting in the drying up of the tree-tops of pines which are 

 overrun by quantities of these insects which keep mostly under 

 the loose pieces of bark on the upper part of the stem." 



Group VII. — Aradus. 



To this group belong the species of the subgenus Quilnus Stal 

 (1873, 137). They are of medium or small size and dark color 

 and have the beak short, not passing base of head, pronotum 

 small, without expanded margins. Our single eastern species 

 is less than 7 mm. in length, the antennae very stout, shorter 

 than head and pronotum together. It is dimorphic in wing 

 length.
