SUBFAMILY APHINAE 193 
Alate Vivipara. Head and thorax blackish; abdomen yellowish olive-green with dusky 
lateral areas and with white, blunt, heavy hairs, giving a slight frosted appearance, especially 
on VII and VIII; legs mostly pale; cornicle dusky. Body length 1.40; hind tibia .47-.60; 
antenna .75, secondary sensoria slightly convex to flat; rostrum slender, obtuse, attaining 
between 2d and 3d coxae. Hairs heavy and blunt, somewhat resembling capitate hairs in life, 
most conspicuous on posterior segments; on antenna very sparse and inconspicuous; on cauda 
pointed, curved, .03-.04 long. Cornicle conical, truncated, with large flange, faintly imbri- 
cated. Cauda broadly semicircular, resembling a body segment, bearing 3 pairs of lateral 
hairs. Lateral tubercles present. 
Ovipara. Color similar to apterous vivipara except that appendages are darker, hind 
tibia entirely dusky brown. Body length 1.62; hind tibia .50; cornicle .05; otherwise as in 
apterous vivipara except hind tibia blackish and moderately swollen for nearly entire length 
and bearing rather large flat sensoria scattered over most of length. 
Male. Alate. Head and thorax dark brown to black; abdomen pinkish to dark rusty 
brown; antenna dusky to black; tibiae sordid yellowish with tips and tarsi black. Body length 
1-1.40; hind tibia .55; antenna .80, Otherwise as in alate vivipara. 
Collections. On leaves and stems of Eriogonum sp. Colorado: Fort Collins. 
Apterous summer viviparae June 7 to Oct. 7, alate viviparae July 8 to Oct. 17, 
sexuales Oct. 6 to 17; rather rare. 
Type. U.S.N.M., No. 41468. Paratypes, Colo. Agr. Exp. Sta. Collection. 
Chief Distinguishing Characters. Character of hairs, especially in aptera 
(heavy, blunt, white, .01-.04 long), semilunar shape of cauda and its width (so 
broad as to resemble a body segment especially in aptera), truncate-conical but 
not mammiform shape of cornicle.

Apterous Fall Vivipara. ‘‘Gray-green; with slight frosty pulverulence partly due to hair.” 
(Mounted in balsam), body pale; appendages pale except tips of tibiae, cornicle, rostrum, 
antenna, cauda and anal and genital plates, which are dusky; tarsi and sometimes cornicle 
dusky. Body length ‘'.858’’-1.1-1.4; across eyes .29-.32; hind tibia .49-.55; hind tarsal II .07-1; 
antenna .55-.70, III .15-.19, IV .11-.14, V .13, VI .08-.09-++.07-.09, sensoria 1-2-4”? on III, 
0-‘‘2” on IV; cornicle .05-‘‘.08’; rostral IV+V .10-.12, attaining between 2d and 3d coxae; 
cauda broad and semicircular to triangular, .04-.06 on median line, .06-.08 on side, bearing 
3 hairs on a side. Hairs on body heavy-spinelike, sharp to blunt, .05-.07 long; on vertex fine, 
pointed, .05-.06; on antenna and hind tibia very short, fine and sparse, hardly visible. 
Alate Vivipara. Head and thorax ‘‘pale dusky to rather dark dusky brown; abdomen 
gray-green with slight frosty pulverulence not due to hairs’; appendages pale becoming dusky 
distally. Body length ‘‘.829”’ to 1; across eyes .30; hind tibia .60; hind tarsal II .09; antenna 
.90, III .25, IV .14, V .14, VI .09+.09; cornicle ‘‘.50”-.07; cauda .05; rostral IV+V .12, attain- 
ing between 2d and 3d coxae. Cornicle truncated-conical, with large flange and with faint 
cross imbrications. Cauda broad, triangular, resembling anal plate, bearing 2-3 pairs of lateral 
hairs. Hairs on body pointed, fine, .02-.03 long and sparse; on antenna and hind tibia minute 
and very sparse. Lateral tubercles present. 
Ovipara. Apterous. Color ‘‘as in apterous vivipara or bronze-green.’”’ Measurements 
same as in apterous vivipara. Hind tibia blackish, considerably swollen along nearly entire 
length and bearing numerous sensoria. 
Male. Alate. ‘‘Head and thorax dusky brown; abdomen light green.’’ Body length 1.25; 
antenna 1, III .25, IV .20, V .17, VI .10-+.10, sensoria about 24 on III, about 15 on IV, about 
ip'on) V, 0 to'27 on VI- 
Collections. On Eriogonum corymbosum. Colorado: Gateway. Apterous 
viviparae Oct. 1 to 19, alate viviparae Aug. 27, sexuales Oct. 19; rare. 
Type. U.S.N.M. Paratypes, Colo. Agr. Exp. Sta. and Hottes Collections. 
Chief Distinguishing Characters. Characters of body hairs (heavy-spinelike, 
varying from sharp to blunt, not uniformly blunt) and length of these hairs 
(longer than .05). 
This species is rather doubtfully distinct from B.’echinata. Not figured 
since, except for hairs, it would be almost a repetition of that for B. echinata.
