SUBFAMILY I. — ARADIN^E. 311 



both Continents, its known range in America extending from 

 Labrador, Quebec and New England west and north to Illinois, 

 Montana, Washington and Alaska. It is not recognized by 

 Parshley as occurring west of the Alleghenies from the region 

 south of Michigan and northern Illinois, but occurs in Ne- 

 braska, New Mexico and California. However, Say's A. rectus 

 (I, 352) which Bergroth (1892, 336) places as a synonym of 

 lugubris, was described from "Missouri and Florida." Parshley 

 makes no mention whatever of Say's species. Other synonyms 

 of lugubris are affinis Kirby (1837, 279) and fenestrate Walker 

 (1873, 36). A form with antennae wholly black is known as 

 var. nigricornis Reut. Of the habits of lugubris about Colden, 

 Ont, in July Van Duzee (1894, 182) states: 



"Several individuals appeared on the trunk of a small maple tree 

 about five o'clock every afternoon. They were very active, leaping and 

 sporting about in the rays of the declining sun, as flies of the Tachinida? 

 frequently do. The reflection of the sunlight from their white glassy 

 wings made these little black bugs look like drops of silver as they darted 

 from point to point, and their activity made it next to impossible to cap- 

 ture them or even to trace them with the eye." 



240 ( — ). Aradus brunnicornis sp. nov. 



Elongate-oblong, sides subparallel. Black; antenna?, veins of elytra, 

 tibia?, tarsi and ventrals in great part, dark reddish-brown ; membrane 

 wholly white; apical fourth or less of connexivals above and beneath 

 dull yellow. Head slightly longer than broad; eyes prominent, protrud- 

 ing beyond apical angles of pronotum; tylus stout, subcylindrical, apex 

 obtuse; impressions of vertex deep, elongate, subparallel; antenniferous 

 spines stout, conical, moderately divergent. Joint 1 of antennae not 

 reaching middle of tylus, 2 subclavate, as long as width of vertex plus 

 one eye, 3 and 4 subequal in length, as stout as apex of 2, united equal 

 in length to 2. Pronotum trapezoidal, widest at basal third, side margins 

 moderately reflexed, finely granulate; hind one broadly concave in front 

 of scutellum; four inner carina? of equal length, subparallel, terminating 

 in front on an obtuse transverse preapical ridge, the usual outer carina? 

 subobsolete; disk evenly granulated, finely transversely strigose between 

 the carina?. Scutellum longer than pronotum, sides feebly elevated, 

 evenly converging almost from the base to the subacute apex. Elytra 

 reaching middle of last dorsal, basal expansion of corium scarcely evi- 

 dent; cross-veins of corium very few, cells largely hyaline. Connexi- 

 vum broadly exposed. Abdomen broader than elytra in both sexes. 

 Length, 4 — 4.5 mm.
