An autumn dressing of gas-lime would be adesirable aiDplication to neglected borders where there are in-fested wall-fruit trees. If by means of experiment it should be found that there isany fluid capable of dissolving the Eed Spiders webs withoutat the same time injuring the leafage, we could thus, byclearing off its breeding-grounds, probably get rid almostentirely of the pest. Hop and Lime-tree Red tiliarum, Miill.; T. tdarius, Claparede. This attack is just mentioned, as an outburst of a specialpest of this land in special states of weather is of I Eed Spider of Lime-trees: web with eggs in dried state, and after beingmoistened, all greatly magnified. Opinions differ as to whether the Eed Spider of theLime-tree is the common Eed Spider, T. tdarius, or a dis-tinct species, T. tilianim (so named, from infesting the Lime),but which is also at times injurious to French Beans andsome other garden-crops. These Acari or mites, which are figured above wereexceedingly injurious in the autumn of 1880, to some Lime-trees at Walthamstow, from which specimens were sent me. HOP AND LIME-TREE RED SPIDER. 141 From their extreme minuteness and transparency, thevarious parts show very indistinctly when magnitied, nnd thenipping-jaws and sucker were not clearly visible. I havetherefore only been able to give the general figure of the mite,with the peculiar long s
