ferns but seeming to prefer damper and more weedy meadows." 

 Drake (1923, 69) says that about Cranberry Lake, N. Y., 

 roseipennis "inhabits the deep woods, lumbered tracts and 'burns' 

 but seems to prefer more or less open areas along trails and 

 tote-roads. It feeds almost entirely upon grass- and herb-in- 

 habiting insects." 



578 (831). Nabis rufusculus Reuter, 1873, 92. 



Elongate-oval. Pale reddish-brown, very finely pubescent, usually 

 with a roseate or pinkish tinge; vertex and front portion of pronotum 

 with the usual median stripe and other dark markings very faint or 

 wanting; a spot behind eyes, another on middle of scutellum, some small 

 dots on apical half of corium and a stripe along sides of pleura and ven- 

 trals fuscous; middle of mesosternum black; antenna? and legs pale red- 

 dish-brown, the femora with numerous small darker dots. Joint 1 of 

 antenna? shorter than head, but longer than anteocular portion, 2 — 4 

 very slender, gradually decreasing in length. Pronotum subconical, about 

 as long as head, sides slightly sinuate, feebly converging to apex, the 

 latter three-fifths the width of base. Elytra (brachypterous form) 

 reaching tip of abdomen, gradually widened from the base, their tips 

 narrowly rounded and membrane very small. Front and middle femora 

 subf usif orm, but moderately swollen ; hind ones longer, very slender. 

 Genital plate of male oblong, its apex bluntly rounded and with a median 

 slit or deeply impressed line reaching back to middle. Length, 6 — 7.5 mm.

Lake Co., Ind., June 7—29 (W. S.B.) ; Sept. 22 (Gerhard) ; 

 brachypterous examples only. Swannanoa, N. Car., June 22 — 

 Oct. 5 (Brimley). Ashland and Sherborn, Mass., May 2 — Oct. 

 15 (Frost). A species of northern distribution, ranging from 

 Ontario and New England west to British Columbia, North 

 Dakota and Colorado and southwest to North Carolina. The 

 macropterous form is usually very scarce. Drake (1923, 70) 

 records both long and short-winged forms as common about 

 Cranberry Lake, N. Y., where it occurs in the somewhat open 

 areas along the trails and tote-roads and on huckleberry bushes 

 in bogs. The eggs were found in the stems of asters which 

 were badly infested by aphids. He states that N. rufusculus, 

 limbatus, fcrus and roseipennis are in that vicinity "pre-eminently 

 wandering, grass- or herb- or very low shrub-inhabiting species 

 and prey upon the insects found on these plants. They are 

 rarely taken, and perhaps never breed, upon tall shrubs or 

 trees." 



579 (832). Nabis inscriptus (Kirby), 1837, 280. 



Elongate, widest at middle of elytra. Dull grayish-yellow, head and 

 front lobe of pronotum strongly tinged with fuscous ; spot behind eye,
