FURTHER NOTES ON ATHIDES 163 



Foodplant. Achillea millefolium, occurring on the flower-stalks. 



Locality. Beauly, Inverness-shire. 



Notes. I took a few apterous and alate viviparous females of 

 this species on milfoil on 17th August. Macrosiphum millefolii, 

 Fabr., was swarming on the plants, but Aphis achillece was not 

 nearly so common. 



Genus Alyzjts, Passerini. 



Myziis cratcegi, Walker. Apterous viviparous females and 

 young, together with a few nymphs and alatre, occurred on the 

 under-surface of the leaves and on the young shoots of hawthorn at 

 Dingwall on 13th July. Cecidomyid larva had cleared off many of 

 the colonies of this aphis leaving nothing but the shrivelled brown 

 skins of their victims. 



Myzus kiBtenbachii, Schon. I swept a number of apterous 

 viviparous females from grass in which clover was growing at 

 Swordale, Evanton, on the loth July. 



Myzus lactucce, Linn. I took a winged male on currant at 

 Swordale, Evanton, on 13th July. 



Myzus solani, Kalt. I found apterous viviparous females on 

 the under-surface of potato leaves at Swordale, Evanton, on 30th 

 September. 



Myzus whitei, Theobald. In the beginning of August I found 

 an alate female of this species on gooseberry. It had been killed 

 by a fungus which has been identified by Mr A. D. Cotton as 

 Empusa Fresenii, Nowakowski. Alate viviparous and apterous 

 oviparous females occurred on currant at Stirkoke, Wick, on the 

 9th September. 



Subfamily Callipterin^e. 



Genus Callipterus, Koch. 



Callipterus quercus, Kalt. Alate viviparous females, nymphce, 

 and larvae were present on the under-surface of oak leaves at 

 Stirkoke, Wick, on the nth September.^ 



Genus Eucallipterus, Schouteden. 



Eucallipterus tilice, Linn. Alate and apterous viviparous 

 females, nymph ae, and larvae occurred on the leaves of a lime-tree 

 at Stirkoke, Wick, on the loth September. 



' This species was erroneously recorded as Callipterus qtierceus, Kalt., in my 

 previous paper on " Notes on the Aphides of Ross-shire," The Scottish Naturalist, 

 April 1918, p. 87.
