seems so close to Buckton' s Amphorojihora that it should probably be 

 sunk as a synonym of it. 



Genus Phorodon, Passerini. 



Phorodon galeopsidis, Kaltenbach. — A few wingless females on 

 Pohjgonum aviculare ; Wye, June and July, 1911, and a winged female 

 on October 14th. 



Genus Rhopalosiphum, Koch. 



Bhopalosiphuvi caltha, Koch. — This marked species I found in 

 abundance in June and July on the king-cup [Galtha palustris). On 

 June 7th I first noticed a few large apterous females on the under 

 sides of the largest leaves in a wood near the Stour at Wye. On 

 visiting them in the following week, each female was surrounded by 

 brownish young, as many as forty around each mother, of various 

 sizes. These patches were always round and the insects remained 

 close together and could not easily be removed, as they held tenaciously 

 to the tissue. Winged females occurred on July 20th, and went on 

 appearing until the plants under observation died. The very marked 

 cornicles might be a sufficient character to separate this insect from 

 the genus in which Koch placed it. In alcohol they gave a deep 

 brown solution. 



Rhopalosipkum herheridis, Kaltenbach." — I found this species 

 in profusion in June on a Berberis in my garden. They had all 

 disappeared by August 20th. Winged and wingless females were 

 always found together. 



B. xylostei, Schrank.f — Found between Wye and Boughton on 

 wild honeysuckle, June 6th, 1911. Evidently this species, but the 

 cornicles are green. 



Genus Sipha, Passerini. 



Siplia (jlycerice, Kaltenbach. — Two colonies of apterous females on 

 Poa aquatica leaves along old river. Wye, July 20th, 1911, with another 

 unidentified species. 



Genus Aphis, Linnaeus. 



Ajjhis myosotidis, Koch. — On wild forget-me-nots, Wye, June 7th, 

 1911. A fev/ winged females and larvae fixed close in young apical 

 growth, often hidden between young leaves and blossom buds. 



A. lychnidis, Linn. — On red robin [Lychnis diurna) at Wye, 

 Crundale, Heme Bay, and Faversham, in June (7th to 30th). Wing- 

 less females and larvae on top of shoots and around flowers ; no 

 trace left on August 1st ; a few in July, also at Ventnor and Hastings 

 in May. Schouteden places this in the genus Myzus. 



A. lantance, Koch. I — Wye, June; curling leaves on apices of 

 shoots of Viburnum lantana, dense masses of wingless females and 

 larvae. Another species found with it, but not yet identified. 



A. umbcllatarum, Koch. — At Wye, Kennington, and Crundale, 



■•'■ Walker placed this in the genus LiosomapJiis, Wlk., but if the genus 

 lihopalosiplium is to stand, I see no reason to change its name. 



■j- Kirkaldy, 1904, places xylostei, ydirank, under the genus Hyadaphis, 

 which Schouteden has adopted. 



\ Mordwilko (1908) places this in his genus Chaitophoroides. It appears 

 to me to be a typical Aphis.
