 Cornicle-about 0.6 mm.

Some wiuglesi3 viviparous females were observed on December 24 and 30, 

 1922. Hitherto unrecorded from Formosa. 



Capitophoriis fnrvwsartemisiae Takah. (Aphididae of Formosa-!, p. 25, 

 1921) is closely related to Capitophm-us pilosus v. d. Goot (Tijdschr. voor Entom. 

 1912, p. 68), but differs from it in the mucli shorter antenna, as well as in lacking 

 sensoria on the 3rd antennal joint of the wingless viviparous female. 



C. formosartemisiae Takali. and C. hrcu/gii Gillette were collected by Mr. M. 

 Kurisaki at Tadono in Wakayama-profecture, Japan, and C. Idppojilmes (Koce) by 

 the autJior on Galcopsis up. at Hakozaki in Fukuoka-pi'efecture, Japan, and on 

 Polygonum sp. at Kyoto and Tokyo, in June, 1923. 



It has never been determined that Phoi'odon galeopsidis Mats. (Trans. 

 Sapporo Nat. Hiat. Soc. vii, pt. 1, p. 15, 1918) is synonymous with Mijzii.fi galeopsidis 

 (Kalt.) or Capitopliorus Jiippophaes (Koch). 



Capitophorus species. 

 Wingless viviparous female 



Yellow. Body oval, provided with a few capitate hairs. Head furnished 

 with a pair of capitate hairs at the middle of the front, as well as on the dorsum 

 between the frontal tubercles. These hairs very stout, almost as long as the 2nd 

 antennal joint, each arising from a very small tubercle. Frontal tubercles distinct, 

 on the inner side somewhat convex and furnished with 2 similar capitate hairs one 

 of which is shorter. Eyes rather small, with small ocular tubercles. Antennae 

 long and slender, imbricated, lacking distinct hairs; the 1st joint much larger than 

 the 2nd, convex on tlie inner side; the 3rd sometimes very slightly curved, without 

 sensoria; the relative length of joints about as follows: in-60, IV-uO, V-45, VI- 

 118 (18 + 100). Rostrum reaching beyond the middle coxae. Sides of the pro-and 

 mesothorax each furnished with a capitate hair, which is almost as long as those on 

 the head. Basal abdominal segments without hairs, the 7th segment furnislied with 

 a pair of capitate hairs on the dorsum, the 8th with 6 similar dorsal hairs which are 

 a little longer than those on the head. Cornicles very long and slender, cylindical, 

 somewhat expanded at the base, almost as slender as, but shorter than, the hind
