The Tropical agriculturist and magazine of the Ceylon Agricultural Society . ig and Apricot trees. Against all such bark and leaf-eating insects, spraying with Paris Green will be found effective. Whenapplied to foliage, it should be mixed with about six times its bulk of lime. A small outbreak of a caterpillar pest (Narosa conspersa, Wlk.), on tea, has been reported from the Uda Pussellawa district. Though belonging to thefamily Limacodidae (which includes the notorious nettle-grubs) this particularinsect has not previously attracted attention as a pest. It does not figure inWatt & Manns Pests and Blights of the Tea Plant. Another insect that has been sent in as a tea pest is the grub of abeetle (apparently a species of Helops). My correspondent reports that •theseinsects are killing out the tea in Teldeniya. Similar grubs were received fromTalawakele, a few years ago. I believe these grubs to be merely feeding indecayed wood of stems that have died from other causes. Specimens of thestems received with the grubs have evidently been dead for many mouths.. Plant Sanitation. 68 In the number of this journal for June, 1905, I gaA*e a list of plantsaffected by the red borer (Zeuzera coffeae). I have now to add to this listtwo species of Citraceae, —the Orange (Citrus aurantium) and the China Lime(Triphasia trifoUata). The outbreak of the Arakkoddian worm (Spodoptera Mauvitia), noted inthe December number of this journal, is reported to have abated. A somewhat similar invasion of the Army-worm (Leucania unipuncta), on cultivated grass in Nuwara Eliya, has been effectively checked by theapplication of Paris Green. The Superintendent of the Government Stock Garden reports thatGuizotia Abyssinica (the source of Rantil Oil) proves to be very attractive tobees. Should this plant come into general cultivation—as it gives promise ofdoing in India—the association of flower and insect should be of benefit to bothapiculturists and growers of Guizotia.
