SUBFAMILY I. — ARADIN^E. 299 



slender, almost as long - as pronotum, antenniferous spines stout, rather 

 short, moderately divergent; impressions of vertex, large, oval, deep. 

 Pronotum as in fig. 26, the side margins broadly flattened, strongly re- 

 flexed, their edges coarsely crenately toothed; disk of front lobe strongly 

 convex, of hind one flattened; discal carinas six, the outer one each side 

 short, the others percurrent, the median pair ending in front in short 

 tubercles; hind margin trisinuate. Scutellum subpentagonal, its apex 

 obtuse. Elytra with basal expansions reaching apex of scutellum, 

 strongly reflexed ; behind them feebly but visibly narrowed to the round- 

 ed tips; clavus and corium with low transverse ridges. Genitals of 

 both sexes as in fig. 26, a and b. Length, 8.5 — 11.5 mm. (PI. II, fig. 26). 



North Bend, Brit. Col., July 6 (Cornell Univ. Coll.). Parshley 

 (1924) has recorded it from Albany, N. Y. A large and rare 

 species of northern distribution, ranging from New England to 

 the Pacific, but not recorded south of latitude 41°. Easily 

 known by its large size and long, slender, parti-colored an- 

 tennas. H. G. Hubbard (1892, 252) has written of it as found 

 on the fungus Cryptoporus volvatus Peck., as follows: 



"This extremely thin and flattened hemipteron, swarms in and about 

 the fungus, and evidently finds the cavity a favourable place of deposit 

 for its eggs. A multitude of its young heaved and tumbled the dust 

 within nearly every fungus. All ages were represented there, but the 

 adult bugs seemed to prefer the heat and warmth of the sun, and are 

 found on the bark of conifers infested with fungus. Their bodies, espe- 

 cially when immature, are particularly well adapted to transport the 

 spores of a fungus. Everything in the nature of dust clings to them, 

 and I have no doubt they constitute one of the most reliable propagators 

 of the plant."

Rather broadly oval. Blackish-brown, basal third and expanded 

 sides of pronotum dull yellow; apical half of scutellum in part or wholly 

 pale brown, tip black; corium, connexivum and ventrals mottled with 

 yellowish ; membrane grayish, vaguely spotted with fuscous ; legs dark 

 brown dotted with yellow, trochanters and tips of tibia? pale. Antenna? 

 slender, almost filiform (fig. 27c), joint 1 dark brown, reaching middle 

 of tylus; 2 dotted with yellow, longer than 3 and 4 united; 3 whitish- 

 yellow, basal third dark brown, shorter than 4. Beak reaching middle 

 of mesosternum. Head slightly longer than pronotum; tylus short, 

 sides parallel; impressions of vertex deep, widely separated; antennifer- 

 ous spines acute, conical, with distinct lateral tooth. Pronotum with side 

 margins broadly flattened, feebly reflexed, remotely bluntly toothed; disk 

 with a transverse elevation across apical third on which the inner lateral 

 carina? end in a tubercle, median carina? well elevated, percurrent; 

 outer lateral carina? short, not reaching middle of disk. Scutellum 

 slightly longer than pronotum, sides feebly elevated, sinuate at middle.
