IV (which are yellow-brown) and entire tibiae black; femora, except tips, brownish yellow. 
Body 2.5-3 by 2, robust and spiderlike or ticklike in appearance; hind tibia 1.5-1.7; hind tarsal 
II .27; antenna 1.3-1.5; rostrum attaining cornicles. Hairs on hind tibia heavy, spinelike, 
rather numerous, length about equalling diameter of tibia; hairs on ventral side of tibia finer 
and shorter, on body .02-.05 long; on cornicle some spinelike, sparse, others very fine and 
numerous. Ocular tubercle small or absent. Young Nymph. Brownish yellow on abdomen, 
paler on thorax, dusky brown on head; bases of hairs dusky; legs colorless, with tips of seg- 
ments and entire tarsi blackish. 
Alate Vivipara. Same as aptera except hairs on hind tibia with length 1.5-2 times the 
diameter of tibia. Fore wing with media twice-forked. 
Ovipara. Same as apterous vivipara except hind tibia, as figured. 
Collections. On Pinus ponderosa var. scopulorum, on bark of tender tips 
standing head downward at bases of needles, solitary, ticklike in appearance 
and action. Colorado: Foothills near Fort Collins, Bellvue and Estes Park. 
Utah: Bryce Canyen and South Long Valley. Fundatrices Apr. 10 to June 12, 
apterous summer viviparae June 16 to Aug. 21, alate viviparae June 20, ovi- 
parae Oct. 1 and 2; rather common but seldom noticed on account of solitary 
habit and head down position among the needles. 
Type. .U.S.N.M., No. 41957. Paratypes, Colo. Agr. Exp. Sta. Collection. 
Metatypes, Hille Ris Lambers Collection. 
Chief Distinguishing Characters. Ticklike general appearance, hardly

length 2.2-2.6; hind tibia 1.25-1.65; hind tarsal II .27; antenna .9-1.1; cornicle with base hardly 
raised, .07 in diameter, sometimes only rim .05 in diameter evident; rostrum attaining ab- 
dominal III. Hairs on tibia rather stout, nearly sparse, length hardly equal to diameter of 
tibia. 
Alate Vivipara. Head and thorax yellowish to rusty brown; abdomen pale rusty yellow, 
paler on median anterior and posterior segments; powdery on head and thorax and interseg- 
mental lines of abdomen; legs pale with only tarsi and extreme tips of tibiae blackish. Meas-

of tibia. Fore wing with media twice-branched. Otherwise as in aptera.
