Chief Distinguishing Characters. Pale body, shape of hairs (blunt and 
minute on I and I, slightly stalked, nearly sessile, funnel-shaped on vertex, 
the same on body but sessile and minute), Macrosiphumlike frontal tubercles, 
moderately long cornicle (about same length as V and longer than distance 
across eyes), rather broad, short cauda (length on median line shorter than 
third length of cornicle) bearing 2 pairs of lateral hairs and short rostral IV-+V 
with needlelike tip. 
Genus Kakimia Hottes and Frison 
Myzus (Kakimia) Hottes and Frison, 1931a:344. 
Kakimia, Gillette and Palmer, 1934:159. 
Characters. Vertex prenouncedly convex; frontal tubercles moderately de- 
veloped, but hardly exceeding vertex, rather Aphislike. Antenna six-segmented, 
as long or longer than body; secondary sensoria subcircular, numerous and 
more or less tuberculate on III and often also on IV and V in alate vivipara. 
Hairs slightly but not conspicuously capitate; on antenna and hind tibia length 
coequal with diameter of segment bearing them, rather numerous. Cornicle 
cylindrical or subvasiform. Cauda medium in size usually with slight con- 
striction but sometimes tapering, rather Myzuslike. Lateral tubercles incon- 
spicuous. Ocular tubercle present. Fore wing with media twice-branched; hind 
wing with both media and cubitus present. 
Genotype (monotypical), Myzus (Kakimia) thomasi Hottes and Frison.
