A LIST OF THE APHIDTDAE OF JAPAN, WITH DESCRIPTION 
Hab. — Hokkaido (Sapporo). 
F. P. — Petasites japanica. 
Nom. Jap. — Fuki-higenaga-abura. 
I got also one of this species from Mr. Jiro Adachi, collected on Cosmos 
bipennata at Osaka. Somewhat allied to M. yomogicola, from which may 
easily be distinguishable by the much longer cornicles and shorter cauda. 
35. Macrosiphum gobonis n. sp. 
Winged viviparous female — Body oblong; dark brown, with a greenish 
tinge ; antennae much longer than the body, fuscous, basal part of the 3rd 
and the 6th entirely paler, frontal tubercles broad, subequal to the first joint, 
the 3rd joint on the outerside with numerous sensoria and on the innerside 
with a few rigid hairs, at the base paler, scarcely shorter than the 4th and 
5th taken together, anterhinarial nearly 8 times as long as the postrhinarial ; 
cornicles very long, cylindrical, slightly curved; cauda greenish yellow, long, 
conical ; wings hyaline, with a yellowish tinge, veins and stigma pale fulvous, 
2nd furcal near the apex of the wing ; legs black, femora at the bases and 
tibiae, except both ends, yellowish. 
Length of body 2-2.3 mm .; ex P- tegm. 8.5 mm.; antennae 3.7 mm.; 
cornicles 1 mm. 
Apterous viviparous female — Nearly allied to the winged viviparous 
female, but the body distinctly larger and broader, frontal tubercles somewhat 
longer than the first joint, the 3rd joint with much less sensoria, and much 
shorter than the 4th and 5th taken together, anterhinarial nearly 6 times as 
long as the postrhinarial. 
Length of body 2.8-3 mm -'> antennae 3.7 mm.; cornicles 1 mm. 
Pupa — Differs from the apterous viviparous female as follows: — 
Body smaller; antennae dark fulvous, frontal tubercles and the first 2 
joint fuscous, the 3rd joint wanting sensoria; wing-sheath reaching nearly 
to the middle of the abdomen ; cornicles at the bases broader, cauda smaller ; 
legs robuster, only the femora at the apices infuscated.
