stained blue as though by fungoid mycelia, and was inclined to think that the 

 chief damage was due to the fungus. Subsequent investigation has not, 

 however, upheld this surmise. 



In February 1905 I visited this plantation at Maymyo, which now forms 

 part of the grounds of The Lodge, the summer residence of the Lieutenant- 

 Governor of Burma. As a result of the investigations made the following 

 points were established : 



(1) That the insect is to be found in the trees in all stages of grub, 



pupa, and beetle in the middle of February. 



(2) That it will apparently attack poles as well as saplings, since 



recently killed poles were ten years old, their outer bark quite 

 thick and rough ; and that trees seriously infested will be killed. 



(3) That it will attack trees on any aspect not only on a southern 



one. The attack investigated in 1905 was situated at some 

 distance from the infested trees discovered by Mr. Long. 



(4) That the insect was a difficult one to deal with in this locality, since 



in spite of the efforts made to stamp it out in 1902 it was 

 abundant in 1905, and appeared to be spreading throughout the 

 station owing to the large amount of planting which was accom- 

 panying the increased building operations. 



In Shillong in April 1906 I found the weevil abundant. Numbers of 

 beetles were cut out from the bark and sapwood of recently felled unbarked 

 logs in the forest. Others were found on the under-surface of the log, 

 sheltered from the sun in interstices of the bark. 



Other evidence of the abundance of this insect in the forest round the 

 station was to be found in the dead poles used to fence in the jumping 

 schools near the polo ground, and in fact for fences of all kinds throughout 

 the place. Large round holes were visible in the bark, and if the latter was 

 removed the elliptical chambers filled with masses of wood- and bark-fibre 

 were to be seen; or, if the bark had fallen off, the semi-elliptical depressions in 

 the sapwood formed sufficient evidence of the former presence of the beetle. 

 And such were very numerous. 



Protection and remedial measures against this weevil, although a some- 

 what difficult matter, are quite feasible when the

Measures P s e dealt Wltn in plantations. 1 he first 



step to be taken is to determine accurately the dates 



during the year at which the trees in any particular locality contain larvae, 

 pupae, and immature beetles. Having decided upon these periods, the whole 

 of the infested trees should be cut out and burnt. Badly infested trees can 

 easily be recognized owing to the fact that tlicir needles commence to turn 

 yellow and the tree begins to fade. In the case of young plantations a little 

 careful observation on the part of Forest Guards should make it possible lor 

 them to be able to mark down attacked trees upon which the needles have not 

 yet turned yellow, since the bark of the trees is invariably coated with a mass.
