The Malayan Aphidide recorded in this paper are represented 
by specimens sent to me by Mr. S. Kiyatake, who collected them 
in the vicinity of Johore. I here express my sincere thanks to 
Mr. Kiyatake for this material. Only about ten species of aphids 
have been recorded from the Federated Malay States, and most 
of them were described from Singapore by P. van der Goot.'
