22-4 PIIOCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



Mr. Kunhi Kannan. One Rupee per gallon. Even when used at full strength, one gallon 

 will treat 200 trees. But now the price has gone up, so we are using an 

 emulsion with soap. 



It might be worth trying an emulsion of soap and creosote. 



There is some description of this Brunolineum in a Bulletin lately 

 issued by the Ceylon Agricultural Department. Just before I left Ceylon, 

 about 25th January, the beetles emerged in large numbers. I have 

 found a predaceous Carabid grub which follows up the track of the boring 

 larva and kills it. Another interesting fact is that the attack depends 

 on the weather conditions. Probably these influence emergence and 

 oviposition, rainfall records and the number of trees taken out bearing 

 a close relation to one another. There are two or three species of para- 

 sites. 



Mr. Fletcher. 



Chrysomelid^. 



Sagra nigrita, Ohv. 



Jacoby, F. I. Chrysom., p. 5; Proc. Second Entl. Meeting, p. 56. 



This species was reared by Mr. E. Ernest Green at Peradeniya, 

 where the larva was found boring in stems of Dolichos lablab, causing 

 large gall-hke sweUings in the stems. It occurred abundantly and did 

 considerable damage. We have not noted it in India as a pest as yet, 

 but it is quite likely to occur. 



Sagra femorata. 



This was found in some numbers by Y. Ramachandra Rao " on bean 

 creeper " at Sidapur, South Coorg. I do not know how far it was 

 damaging any cultivated crop, but, in view of the record of S. nigrita on 

 Dolichos lablab, it seems better to include it for the present. 



Leitia downesi, Baly. 



Jacoby, F. I. Chrysom., p. 43. 



At Pusa the eggs have been found laid singly or in rows, usually on 

 the upper surface of leaves of Panicum sp., the larva eating one epidermis 

 and the mesophyll substance of the leaf, and leaving the other epidermis 

 intact. Pupation takes place in soil in a shght cocoon. The hfe-cycle 

 from egg to adult is about 17 days at the end of August. One female 

 laid 227 eggs between 19th and 30th August and was then lost. We 

 have it also from Chapra. 



This species is not known as a pest, but might easily be one.
