to lugubris. Differs in its smaller size and by characters given 

 in key. 



241 (387). Aradus abbas Bergroth, 1889, clxxx. 



Elongate-oblong. Head, pronotum and scutellum black or dark 

 brown ; elytra and under surface grayish or fuscous-brown ; membrane 

 hyaline, mottled with quadrate fuscous spots; antenna? fuscous, the tip 

 of second segment and apical half of third white, fourth black. Head 

 as long as broad; tylus short, stout, cylindrical; antenniferous spines 

 slender, acute, feebly divergent; antenna? very slender, as long as head 

 and pronotum united, second joint more than twice the length of third, 

 the latter one-half longer than fourth ; beak reaching middle third of 

 mesosternum. Pronotum much narrowed from middle to apex, side 

 margins not flattened, slightly reflexed, feebly sinuate, finely and irreg- 

 ularly granulate, hind angles rounded; disk with four nearly entire 

 moderately elevated carina?, the basal one each side evident. Scutellum 

 narrow, elongate-triangular, apex subacute, sides rather strongly ele- 

 vated ; disk with median elevation and fine transverse ruga?. Elytra in 

 both sexes reaching apex of abdomen. Male with fifth ventral much 

 shorter at middle than sixth, genital segment large, strongly convex; 

 hind margin of dorsal genital of female with small notch at middle. 

 Length, 4.6—5.5 mm. (PI. Ill, fig. 47). 



Lake Waccamaw and Terra Ceia, N. Car., April 16 — Septem- 

 ber (Brimley) . Iditarod, Alaska, July 27 (Gerhard) . A small, well 

 marked species of wide distribution, its known range extending 

 from Newfoundland, Quebec and New England west and north- 

 west to Washington, British Columbia, and Alaska and south 

 and southwest to Florida and California. Known from both 

 Michigan and Illinois but not as yet from Indiana. The only 

 Florida station recorded is Atlantic Beach by Mrs. A. T. Slos- 

 son. Superficially this species resembles lugubris very closely. 

 It is best distinguished by the more slender antennae, the sec- 

 ond joint of which is much less clavate, being only slightly en- 

 larged near apex. 



242 (388). Aradus breviatus Bergroth, 1887, 245. 



Female — "Color and structure as in abbas; posterior lateral mar- 

 gins of pronotum distinctly oblique; elytra extending well beyond apex 

 of abdomen. Dorsal genital segment apparently much abbreviated ; sec- 

 ond dorsal genital visible from above (through the wings) ; ventral gen- 

 ital segments as in abbas except that the genital lobes are truncate, 

 scarcely extending beyond apex of first genital segment. Length, 5 mm." 

 (Parshley). (PI. II, fig. 48). 



Known from a single Florida female in Bergroth's collection. 

 Of it Parshley (1921, 86), who examined the type, says: "It
