SUBFAMILY APHINAE 25 
Apterous Summer Vivipara. Nymph. Body pale yellow to brownish with two longitudinal 
rows of pale greenish spots; lightly covered with pulverulence. Cornicle, tarsi and genital 
plate black. Adult. Body yellow-brown to dark brown; dorsum mostly covered with heavy 
powder leaving a naked dark band on abdominal V and only spots and dashes on other seg- 
ments; venter lightly pulverulent; legs pale except mere tips of tibiae and of antenna. Ros- 
trum, entire tarsi, cauda, cornicle, anal and genital plates black. 
Body length 3-4; hind tibia 1.3-1.7; antenna 1.10-1.17; cornicle in life covered with pow- 
der to diameter of .14; rostrum attaining 3d coxa to abdominal II. Hairs rather fine; on hind 
tibia 1.5 times as long as diameter of tibia. 
Alate Vivipara. Same as aptera in color and measurements. Hairs on hind tibia 2-3 times 
as long as diameter of tibia. 
Ovipara. Apterous. Head and thorax dark; abdomen pale yellow with dark band on ab- 
dominal V and dashes and spots on other segments; covered except on dark areas with pulveru- 
lence as in vivipara and also with entire body posterior to cornicles heavily pulverulent; 
cornicle black; entire hind tibia dusky. Measurements same as apterous vivipara. Hind tibia 
considerably swollen on distal half and thickly covered with sensoria along entire length. 
Male. Alate. Body blackish brown; more or less powdery. Body length 2.20; antenna 
1.34; hind tibia 1.46. Otherwise as in alate vivipara. 
Egg. Black; naked. Size 1.25 by .55. 
Collections. On Picea pungens, on bark of twigs and small branches; in 
colonies. Colorado: Boulder, Denver and Fort Collins. Utah: Nephi, Salt Lake 
City, River Heights and Logan. Fundatrices Apr. 13 to 21, apterous summer 
viviparae Apr. 22 to July 26, alate viviparae May 11 to June 22, sexuales Oct. 
23 to Nov. 13; rather common in parks. 
Type. U.S.N.M., No. 41940. Paratypes, Colo. Agr. Exp. Sta. Collection. 
Chief Distinguishing Characters. Pale body, of nymphs especially, and 
pale appendages, heavy pulverulent covering, long hairs on tibiae, length of III 
(not less than .40), length of rostral IV (.19-.24) and considerably swollen hind 
tibia in ovipara (about twice normal diameter). 
The fact that infestations of this species have been found mostly in parks 
and cities instead of in nature may indicate that it is introduced. Indeed, the 
resemblance to C. piceicola is very close, but Cholodkovsky states “little pul- 
verulence” while C. braggii is heavily pulverulent, III of alate vivipara of 
braggii shows fewer sensoria (1-4 not 4-7), and hind tarsal II is shorter than 
that of C. piceicola (.25-.32, not .38-.49). 
This species is very close to C. glehna (Essig) and was formerly considered 
identical by the author but further study throws doubt on this synonymy. 
The only differences appear to be as follows: The longer III (.40-.56 not .31), 
longer rostral IV (.19-.24 not .17) and paler appendages (not mostly dusky).
