ADDITIONS TO THE LIST OF KENT APHIDID^. 

 By Fred. V. Theobald, M.A. 



The following aphides were found in Kent in 1914-1915, 

 and are additions to the lists I have already published in this 

 Journal. Besides those mentioned here, I have a handsome 

 new species of Macrosiphum found swarming on red valerian 

 {Centhranthus ruber) on the chalk cliffs at Margate and at Wye ; 

 a new Macrosiplmm on red lamium {Lamium 'purpureum), and a 

 new Rhizohius on the roots of spruce {Picea sitchensis). 



Macrosiplmm fragarice, Koch. — This very fine green mealy 

 species with black head, legs, and long thin outwardly curved 

 cornicles, was found at Wye, June 30th, 1914, on leaves and 

 stalks of the strawberry, and on the valerian {Centhrantlmn 

 ruber) ; alate females were just appearing. They occurred in 

 company with Macrosiphum centhranthus, nov. sp. 



Macronphoniella chrysanthemi, Del Guercio. — Alate and 

 apterous females in the end of September, and on to December 

 both out of doors and under glass on cultivated chrysanthemums 

 at Wye and Maidstone, doing a considerable amount of damage. 



Aphis urticaria, Kaltenbach. — Abundant on nettles, Wye, 

 June 7th, 1914, and June 21st, 1915, and swarming on wall 

 pellitory {Parietaria officinalis) May to October, both apterous 

 and alate females, somewhat smaller than those on the nettles 

 in June and July, 1912-1914. 



Aphis adjecta, Walker. — Littlestone and on Eomney Marsh, 

 June 14th, 1914, on the flower heads of the hound's-tongue 

 {Cynoglossum officinale) ; many apterous females. This marked, 

 very small yellow species does not seem to have been recorded 

 since it was described. 



Apliis infuscata, Koch.— Eomney Marsh, June 14th, 1914, 

 on Prnnus spinosus — alate and apterous females, curling up the 

 small leaves, some of which were pale yellow and pink. 



Aphis helichrysi, Kaltenbach.— Bearsted, June 13th, 1914, 

 alatae and apterae swarming in the flower heads of the yarrow 

 {Achillea millefolium). 



Aphis anthrisci, Kaltenbach. — On flower stalks and blossoms 

 of Anthrisciis, sp,. Wye, July 8th, 1914. This species was much 

 attended by ants, which swarmed over the two colonies I found, 

 and yet they did not appear to be producing much " honey 

 dew." 



Aphis sedi, Kaltenbach.— On the yellow sedum or wall pepper 

 {Seduni acre) at Littlestone, June 14th, 1914, and Wye, July 

 17th, 1914 ; two alate females, and two apterae. Apparently 

 very rare in this district of England, as I have frequently 

 searched for it and only managed to get three specimens at 

 Littlestone and one at Wye la'^t year. 



Aphis chrysanthemi, Walker. — Clustering on the flower stalks
