PKOCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 223 



In Coorg I collected beetles from lemon and Citrus trees. They were Mr. Ranatlardia 

 resting on the leaves and, when disturbed, they fly about actively. Rao.

 This was sent in to us in 1918 from Bangalore by Mr. Anstead who Mr. Fletcher, 

 found the larva boring into orange branches. Mr. Anstead states that 

 the eggs are deposited in June in the axils of young Uving twigs and never 

 on dead wood or old branches. The eggs are covered with a sort of ydlow 

 transparent varnish. As soon as the eggs hatch the yotmg larva bores 

 into the twig and works upward for about half-an-inch to an-inch-and-a- 

 half and then makes two t'liy holes about the size of a pin's head. It 

 then turns back and bores down the twig, occasionally making small 

 openings. Finally it gets into the main branches where it makes tunnels 

 a quarter-of-an inch in diameter. The young twigs that are bored at 

 once die and turn black so that they are conspicuous and they can be 

 cut off with the larvae inside them. By doing this and by hand-collec- 

 tion of the adult beetles the attack can be controlled to a large extent. 

 The eggs appear to take about two weeks to hatch out.

We have this from North and South Coorg and the Nilgiris. It is 

 the well-known " Coffee-borer " of South India, which was discussed 

 fully at the last Meeting in 1917. Since then I have not visited the Coffee 

 Districts and have therefore no more to add. 



The length of the hfe-history is one year but it may vary. The jij_ gmijij gajman. 

 bushes may be infected with eggs laid by the April brood. The method 

 of egg-laying is very interesting. The egg is always laid in a crevice ; 

 if it is laid anywhere else, the grub fails to penetrate into the wood. 

 Scrubbing the plants is successful to prevent egg-laying and to destroy 

 the eggs when laid. The eggs are never laid loose on the tree. The 

 larvae take from two to two-and-a-half months to eat into the wood. 

 To check them in this stage Brunolineum has been used. The larval 

 excrement in the tunnels is not very compact so that the fumes enter the 

 gallery and kill the larva. This chemical might be tried on all sorts of 

 borers in fruit-trees. It is not known exactly what it is but it is perhaps 

 a tar distillate. 



What does it cost ? BIr. Fletcher.
