and eggs and dead females were found in June in the soil round the- 

 trunks within a radius of six feet ; in the case of dry soil they occurred 

 to a depth of three inches. Experiments arc in progress on the 

 survival of the eggs under various conditions. 



The following pests were noted as occurring in destructive numbers : 

 Epilachna dodecastigma on seedling egg-plants, Diacrisia obliqua 

 on jute, soy beans, Dolichos lablab, and cowpeas, Eitphalerus citri on 

 orange and lemon, Bagrada picta on radish, and Helhda imdalis and 

 Chrotogonus sp. on cauliflower and seedling egg-plants. 



Brief notes are given on the following insects : Laphygma exigua, 

 found on various new food-plants, including Colocasia antiqnoriim, 

 Ranunculus sderatus, Polygonum glabriim and Runicx maritimus ; 

 Prodenia litura, found on Polygonum glabrum ; Agrom3/zid larvae 

 mining the leaves of Imda vestita, Cnicus arvensis, Nepta rudinalis, 

 Pisum arvense, and Brassica campestris ; and larvae of Stromatium 

 barbatum boring in dead wood, which were hatched in June 1917 and 

 were still living two years later. Exelastis pumilio, Z. [liophanes, Meyr.) , 

 was reared from a larva found on a wild vetch. An Anthomyiid 

 fly was found boring in the larval stage in Imperata arundinacea, 

 causing dead-heart ; the adults emerged in November. Olenecamptus 

 bilobus was reared in November from larvae found boring under the 

 bark of a fallen tree {Ficus glomeraia). This beetle is at times a pest 

 of cultivated figs. Acrocercops syngramma, Mej^r., was reared from 

 larvae mining leaves of mango.

This paper deals with certain pests enumerated in a list of Indian 

 pests already noticed [R.A.E., A, ix, 68]. The weevil, Pempheres 

 affinis seems to be widely distributed in cotton areas, and is being 

 studied. It breeds freely in Corchorus olitorius, in two species of 

 A butilon and in Hibiscus rosasinensis, H.esculentus andii/. cannabinus 

 (Deccan hemp), and, after cotton was off the ground, was found in Ficus 

 religiosa. Attempts are being made to find a resistant strain of 

 cotton. A parasitic grub has been found in the larva, and both 

 larvae and adults are attacked by a fungus. The continual pulling 

 up of cotton plants seems to have no appreciable effect on the numbers 

 of this pest. Generally only seedlings and young plants are attacked. 



Another beetle, Hispa armigera, is a serious pest of all three crops 

 of paddy in South Kanara. Crude oil emulsion acted as a deterrent 

 and was successful where seed beds were taken in time. Bagging 

 and clipping were equally efficacious. Great success was obtained 

 in one field where it was possible to flood by running in water with 

 crude oil emulsion floating on it. This might be a useful method 

 to use with the first crop, but the insect needs further study before 

 the best remedy can be determined. The damage done by Platyedra 

 gossypiella, Saund., has been much reduced by the enforcement of the
