useless as applications for destroying the pest, but washes made of 

 dilute kerosine emulsion or of phenyle are found to be efficacious; the projDor- 

 fcions recommended are one part of kerosine emulsion to eig-hty parts 

 of water, or one part of phenyle to two hundred and forty of water. The 

 wash should be applied in the evening- or on a cloudy day, as hot sunshine, 

 following" its application, is apt to scorch the leaves. In the case of 

 phenyle the application of the wash should be followed the next morning 

 by a copious drenching with ordinary water. 



The specimens were submitted to Mr. G. B. Buckton, who kindly 

 examined them and reports that the insect belongs to a new genus and 

 species of Aphidse which be names Ceylonia theacola. 



The following is his note on the subject : — 



** The Cej'lon Tea Aphis appears to be anomalous and uuclescri'oed, and the form has 

 no representative in Europe, as far as I know. In the general appearance of the body, 

 the antenn£e, and the cornicles, it follows the genus ApMs, but the single furcation of 

 the cubital vein sharply separates it from that genus, and in this particular it more 

 nearly follows Schiznneura. I presume, however, that the Tea Aphis neither rolls 

 leaves nor forms galls, neither has it a flocculent covering. The lower wing also shows 

 some modification in the disposition of the oblique veins. 1 think it will be desirable 

 to place this Aphis under a new genus, and for the present I suggest for its name Ceylo' 

 nia thececola, which is trivial and not therefore binding to any particular character. 



" Genus Cetlonia. 



" Antennge long and seven-jointed, third and fourth joints nearly eqnal. Cornicles 

 cylindrical and rather long. Upper wings with the cubitus once forked. Stigma 

 large ; oblique veins two. Lower wing with two oblique veins running nearly parallel 

 to each other ; tarsus with one joint." 



" Ceylonia thececola, nov. sp. 

 " Colour dark brown or black. Apterous insect, globose, shining, finely punctured. 

 TTead square. Antennae long, seven-jointed, ochrous yellow, with black wings. 

 Abdomen with a row, on each side, of small pores. Whole insect punctured. Legs 

 dirty ochrous, with dark femora. Cauda black and hirsute, cornicles cylindrical. Size 

 of body 0'055 inch. Winged female coloured much like the above. Wing voluminous, 

 with a brownish membrane much punctured. Underside all brown. Rostrum reach- 

 ing just beyond the third pair of coxae. Expanse of wings 0'19 inch. Body 0'04 inch. 

 These insects stain weak alcohol a fine port wine red colour." 



Specimens of the rice sapper [Leptocorisa acuta, Thumb.) have been 

 received from Mr. J. Cripps, of Chumparan, where the insect is said to 



have been very destructive to the ears of 

 The Bice Sapper in Chumpa- Bliuddai paddy, which is harvested about 



October. The insects work chiefly on 

 cloudy daj's and at night, and retire to the foot of the plants in hot 

 sunshine. The cultivators are said to strew the fields with fresh buffalo 

 dung, covered with buffalo buttermilk, in which an insect is said to breed
