Fundatrix. Apterous. Dull sordid yellow to blackish, in older individuals with broken 
transverse bands of very dark olive-green over most or all of dorsum; head, appendages and 
genital plate dark. Antenna and dorsum of body denticulate. Body 1.25-1.5 by 1; shape stout 
pyriform; hind tibia .22-.26; hind tarsal II .07 long; antenna .30; cornicle about .09 in diam- 
eter at base of flat cone. Hairs on body simple, short and sparse. 
Alate Vivipara. Same as ovipara except longer legs, hind tibia about .60-.68 and lacking 
waxy secretion on posterior segments of abdomen. 
Ovipara. Alate. Color about as in fundatrix; sides of abdominal IV to VIII with heavy 
tuft of cottony secretion. Body length 1.50-1.70; antenna .65-.85; rostrum barely attaining 2d 
coxa. 
Male. Alate. Light yellow, head black on front and lateral margins, scutellum and 
mesothoracic lobes dark; appendages more or less dusky. Body length .80-1.; antenna .80. 
Gall. Pod-shaped gall formed by one-third of leaf folding lengthwise on remaining two- 
thirds, enclosing the lice and swelling so as to resemble a minute pea pod, either green or red, 
10-20 long. 
Collections. On Arctostaphylos uva-ursi, on leaves. Colorado: Foothills 
above Bellvue, Fort Collins, Big Thompson Canyon, Ward and Estes Park. 
Utah: Bryce Canyon. Fundatrices July 15 to Aug. 8, alate viviparae Aug. 5 to 
Oct., sexuales Aug. 5 and 22; rather rare. 
Type. U.S.N.M. 
Subtribe Panaphina n.n. 
Callipterina Baker, 1920a:25. 
Characters: Antenna generally bearing only minute hairs or bristles (except 
Panaphis). Cornicle truncate, never much longer than broad at base; not retic- 
ulated; sometimes a mere rim or pore (Monellia). Cauda usually knobbed, or 
rounded, rarely elongate; anal plate usually indented or bilobed in viviparae. 
Rostrum obtuse, V indistinct (fused with IV). Aptera usually with capitate 
hairs. Viviparae, including fundatrix, usually alate. Fore wing with media 
twice-branched, radial sector usually faint (except Euceraphis). Living on 
leaves or bark, usually solitary; active when disturbed. 
*Baker’s statement (op. cit.) that the media of fore wing is once-branched is evidently 
an error or based on an exceptional specimen. No such statement occurs in the de- 
scriptions by Cockerell (1905:391), Cowen (1895:125) or Gillette (1909d :41) for the 
Colorado examples nor by Davidson (1911a:559) or Essig (1915: 187) in their descrip- 
tions of the California specimens. The numerous alate examples in the collection of 
the Colo. Agr. Exp. Sta. all show media of fore wing twice-branched.
