Among these are some of the well known pests, such as Siphonophora roses on roses, Phorodon hiimuH on the hop, Myzus cerast on cherry, M. ribis on currant, etc. But there are others of more interest. The/axes betiiUna, a species of a very small genus, has, I believe, only been recorded from Guestling. The fine aphis Lachmis longipes is not so remarkable for its long legs as for its very long wings, which exceed those of any other British aphis ; it has been sent from Ewhurst. Dry- obius roboris, from Guestling and Ore, has conspicuously mottled wings. Some of the aphides cause galls ; thus Pemphigus spirotheca forms spiral galls on the petioles of the leaves of poplar, "tetraneura ulmi lives in erect, often pedunculated galls on the upper surface of elm leaves. Schizoneura ulmi, also on elm, causes the leaves to become distorted, pale and bladdery. Chermes abietis inhabits conelike galls on the spruce fir, while Phylloxera punctata, which is common, causes yellow spots on the leaves of the oak and is nearly allied to P. vastatrix, the dreaded pest of the vine. 237
