Amphorophora, species Takahashi, Aphididae of Formosa, pt. 2, Report 

 No. 4, Dept. of Agr., Government Research Institute, Formosa, Japan, 

 1923, p. 32. 



Takahashi discusses this form without giving it a name, simply 

 calling it Amphorophora, species. While I have not seen it, I do not 

 recognize it from his description as belonging to any of the named 

 species in this genus. It is evidently a border line species between 

 Amphorophora and Macrosiphum. I take pleasure in naming it 

 after Takahashi and quote his description. 



Wingless viviparous female. — White, somewhat pale yellowish. Eyes black. 

 Antennae white, apices of the third, fourth, and fifth joints, and the sixth black. 

 Cornicles white with black apices. Legs white, apical halves of femora, apices 

 of tibiae, and tarsi black; tibiae somewhat pale brownish on the basal half. 

 Cauda white. Body oval, with some short bristles. Frontal tubercles large, some- 

 what convex on the inner side. Antennae very long and slender, provided with 

 a few short hairs; the third joint provided with one or two small circular sensoria 

 near the base; the fourth very slightly imbricated, lacking sensoria; the relative 

 length of joints as follows: III-75, IV-53, V-48, VI-115 (18 + 97). Rostrum 

 reaching beyond the hind coxae. Cornicles long, a little longer than the fourth 

 antennal joint, about 1.8 times as long as the cauda, cylindrical, very slightly 

 dilated about the middle and on the base, with a little imbrication at the tip. 

 Cauda large, ensiform, with a few lateral bristles. Legs very long and slender; 

 tibiae provided with many short bristles; tarsi rather short.
