grubs and the other against the adult beetles. 

 The larvae live in the ground and feed on roots 

 of plants and are full grown just before the 

 rains commence. If then the soil is thorough- 

 ly hoed up these grubs can be collected and 

 destroyed in large numbers. It often happens, 

 however, that the beetles breed outside the 

 garden area and the adults fly in from outside 

 to do damage by eating the leaves by night. 

 They may be caught then by searching on 

 the plants at night with a lamp and hand 

 picked and dropped into a bucket of water 

 with a film of oil on top ; or they may be some- 

 times attracted in large numbers to a light 

 placed over a tub of oil and water into which 

 they will fall. Spraying with a stomach 

 poison in May will protect the plants. Lead 

 Arsenate at the rate of half an ounce to four 

 gallons of water, or Lead Chromate at the 

 rate of one and a half ounces to four gallons of 

 water may be used; both these poisons can be 

 obtained from D. Waldie & Co., Calcutta. 



Long slender smooth caterpillars, with 

 longitudinal stripes of red and white, rest 

 upon the ribs of the leaves and feed upon the 

 green parts at night. Their presence can be 

 detected by their habit of glueing two or 

 more leaves together to form a shelter; these 

 leaves should be pressed together when dis- 

 covered. They pupate in small cocoons in 

 the folds of the leaves and develop into small 

 grey moths. They can be poisoned by spray- 

 ing with Lead Arsenate dissolving one ounce 

 in four gallons of water. 



Scale insects which look like tiny white 

 specks with a reddish centre on the stems 

 and tender sides of leaves, attack the plants to 

 a great extent. Spraying with Kerosene 

 Emulsion is a good remedy. 



Green fly or aphis which usually appear 

 when the flower buds are forming, are for-
