A SECOND LIST OF THE APHIDID^ FOUND IN KENT. 

 By Fred V. Theobald, M.A., F.E.S., &c. 



(Continued from p. 356.) 



A2)his solani, Kaltenbach. — Wye, June 26th, 28th, July 7th, 1911, 

 a few apterous females beneath potato leaves, and a single winged 

 female on June 28th. 



A. tragopogonis, Kaltenbach. — On Tragopogon pratensis, Wye, 

 August 12th, 1911, and Heme Bay, July 18th, 1911, and on Schor- 

 zonera at Wye and Heme Bay, July 15th and 20th, 1911. 



A. cratcegiella, nov. nom. for. 



A. cratcegi, Buckton (non Kaltenbach). — Common on the top 

 shoots of hawthorn in hedgerows, Wye, and Godmersham, forming 

 large dense colonies, May 22nd and 29th, June 7th and 10th, July 

 1st and 18th, September 20th, 1911. One apterous female had black 

 cornicles. Kaltenbach's A. cratcegi is black, Buckton describes and 

 figures a green species which is quite distinct. The two species I 

 have twice found together. 



A. malvcs, Koch. — A few apterous females on the leaves of the 

 dwarf mallow {Malva rotundifolia) in Wye churchyard, August 22nd 

 to 27th, 1911. Apparently rare. 



A. lappcB, Koch. — ^On cultivated celery, sometimes freely on the 

 leaves, at others in masses hidden between leaf stalks. Wye, Septem- 

 ber to November, 1907 ; also sent me from Ely in September, 1909. 



A. cratagi, Kaltenbach (non Koch, non Buckton). — Wye, on 

 hawthorn. May 29th, September 12th, 1911 ; also from Haddenham, 

 Cambridgeshire. 



A. ochropus, Koch. — On Bumex, Wye Downs, July 30th, 1911, 

 a single dense colony of winged and wingless females and nymphs. 



A. ilicis, Kaltenbach. — On holly leaves, Wye, a few scattered 

 wingless females ; also found at Hastings, May 3rd, 1911, a single 

 colony on a leaf. 



A. cracccB, Linn. — A few wingless females on Lotus corniculatus, 

 along Olantigh Eoad, Wye. This appears to be the A. vicica of 

 Fabricius. 



A. opima, Buckton. — Wye, on begonias, March 27th, 1903, under 

 glass. 



A. atriplicis, Buckton (non Linn.). — The only black aphis I have 

 found on mangolds, and which has swarmed and done enormous 

 damage this year, answers to Buckton's description of his A. atriplicis. 

 It is, however, apparently only A. papaveris, Fabricius. This 

 black Aphis curls the leaves and twists them up into crinkled masses ; 

 abundant all over Kent on mangolds, most so in Thanet. 



A. lactuccB, Kaltenbach. — Wye and neighbourhood. This is a 

 true Aphis, found in great alDundance on sowthistles {Sonchus 

 arvensis and S. pahistris), also on garden lettuces run to seed. The 

 pale bright green wingless females and larvae collect in numbers on 

 the flower stalks and fall on being shaken, especially the adult 

 females. First noticed on June 27th and continued on through Sep- 

 tember. No winged females have been found. The shiny brown
