Type. U.S.N.M., No. 41467. Paratypes, Colo. Agr. Exp. Sta. Collection. 
Chief Distinguishing Characters. This species belongs to the coweni-fili- 
foliae complex which is very peculiar on account of the weak Aphislike frontal 
tubercles combined with the large Macrosiphumlike cauda, cornicle and an- 
tenna. The hairs are slightly capitate and unusually long for Macrosiphum thus 
resembling Kakimia. 
From the other species of this complex this form is distinguished as follows: 
Length of cornicle comparatively short (.36-.50 and shorter than antennal IV), 
long unguis (about twice length of cornicle), moderately numerous sensoria on 
III (8-10 in apterous and 18-20 in alate vivipara).

Macrosiphum katonkae, Gillette and Palmer, 1934:184; Hottes, 1948a:30. 
Apterous Summer Vivipara. Green; cornicle dusky brown except base; cauda dusky yel- 
low; antenna dusky beyond proximal half of III; tibiae dark brown. Body length 2.74-2.85; 
across eyes .53; hind tibia 2.45; antenna 3.5-4.2; rostrum attaining 2d coxa. Hairs slightly 
capitate; on side of abdomen .04. Cauda tapering and slender, bearing 3-4 pairs of lateral 
hairs and a single dorsal] one some distance before tip; hairs near tip straight and sometimes 
capitate. 
Alate Vivipara. Head and thorax green to dusky; otherwise same as apterous vivipara 
except as figured. 
Ovipara. Apterous. Same as apterous vivipara except as follows: Cauda .40 on median 
line, .50 on side and hind tibia with nearly the proximal half slightly swollen and bearing 
numerous sensoria.
