Kakimia alpina (Gillette and Palmer) 
Myzus alpinus Gillette and Palmer, 1928:18. 
Kakimia alpina, Gillette and Palmer, 1934:160. 
Apterous Fall Vivipara. Light green; appendages pale to brownish with tarsi, tips of 
antennal III and IV and entire VI blackish. Body length 1.90-2.20; across eyes .44-.47; hind 
tibia 1.10-1.60; hind tarsal II .11-.13; antenna 2-2.60, III .47-.60, IV .29-.42, V .30-.39, VI .11- 
-13+-.65-.90, sensoria 5-13 on III; cornicle .25-.40; cauda .19 on median line, .24-.28 on side. 
Hairs slightly but distinctly capitate; on vertex .03-.04; on antennal III .02, on hind tibia and 
body .03-.04; in the two latter cases shorter than diameter of segment bearing them. Cornicle 
cylindrical to subvasiform, imbricated. Cauda rather spoon-shaped and Aphislike and bearing 
2 pairs of lateral hairs and a single dorsal preapical one. Rostral IV+V .18, attaining 
3d coxa. 
Alate Vivipara. Head and thorax black; abdomen light to medium green with broken 
dorsal bands and lateral areas; antenna, cornicle and cauda black; legs dusky. Body length 
1.50-2.25; across eyes .44; hind tibia 1.45-1.75; antenna 2.50, III .60-.62, IV .36-.43, V .35-.39, 
VI .11-.13-+.75-.90, sensoria tuberculate, 30-45 on III, 9-15 on IV, 0-6 on V. Hairs blunt or 
slightly capitate; .02-.03 on vertex and antenna; on tibia and body .03-.04. Otherwise measure- 
ments as in apterous vivipara. Lateral tubercles present on prothorax and abdominal I to VI. 
Collections. On leaves and stems of Castilleia sp., Orthocarpus luteus and 
Pedicularis paysoniana. Colorado: Pingree Park (alt. 9000 ft.) and Cameron 
Pass. Apterous summer viviparae Aug. 18 to 24, alate viviparae Aug. 18 to 26 
(after this date all became alate), alate males Aug. 26; plentiful but difficult to 
find on account of position in leaf axils. 
Type. U.S.N.M., No. 41469. Paratypes, Colo. Agr. Exp. Sta. Collection. 
This form seems to differ from Colorado specimens determined as K. cy- 
nosbati only in host plants and habits. On the Orthocarpus, at least, only alate 
viviparae and alate males are found at the end of summer, suggesting the 
possibility of migrating to another host, possibly Ribes. However, attempts to 
transfer fall alatae to Ribes have not yet been successful. The Ribes leaves 
appeared to possess no attraction whatever. It accordingly seems best to leave 
the two forms stand as separate species for the present. 
Kakimia cerei Gillette and Palmer 
Kakimia cerei Gillette and Palmer, 1933:354 and 1934:161. 
Alate Vivipara. Head and thorax brown; abdomen pale yellow or greenish without 
markings; cauda and cornicle pale to slightly dusky; antenna pale on I, II and base of III, 
dusky distally; tibiae dusky; tarsi and tips of tibiae black. Body length 1.80; across eyes 
.42; hind tibia 1.25-1.7; antenna 2.2, secondary sensoria somewhat tuberculate, scattered along 
entire III; rostrum attaining 3d.coxa. Other characters as in apterous vivipara. 
Apterous Summer Vivipara. Color same as in alate vivipara except that tibiae are pale. 
Body length 1.70-2; hind tibia 1.20-1.60; antenna 1.80-2.23. Hairs blunt to slightly capitate; on 
vertex, antenna, hind tibia and side of abdomen .03-.04 long and nearly erect. Cornicle cylin- 
drical to subvasiform, imbricated, imbrications more or less denticulate. Cauda parallel-sided, 
with slight neck, bearing two pairs of lateral hairs and a single dorsal preapical one, distal 
hairs slightly capitate. 
Ovipara. Apterous. Pale yellowish green; appendages pale except tarsi, tips of tibiae 
and antenna which are blackish. Body length 1.75-1.80; antenna 1.20-1.25; hind tibia with 
proximal half slightly swollen and covered with scattered sensoria. Otherwise as in apterous 
vivipara except that cauda is shorter and stouter. 
Male. Alate. Same as alate vivipara except entire appendages black and antenna as 
figured.
