attacked, but healthy palms usually recover. This moth also feeds, 

 on the leaves of palmyra palms [Borassiis] found on uncultivated lands. 

 Remedial measures include the use of light traps. These consist 

 of an oil lamp placed in the middle of a flat shallow pan at least 24 in. 

 across and raised about 5 ft. off the ground, and should contain water 

 and some kerosene or coconut oil. At least three should be used to 

 the acre at the beginning of an outbreak, except on wet nights and 

 in bright moonlight. Bright fires are only useful if made of infested 

 coconut leaves. They are not recommended for general use at night 

 unless the infested leaves cut during the day are burnt. Smoky 

 fires of tar and sulphur are of no real value. Spraying is not recom- 

 mended at present. All infested leaves or parts of leaves should be 

 cut off and burnt within 12 hours of removal. Palms should be kept 

 healthy by cultivation and manuring, and remedial measures should 

 be adopted directly the pest is observed. 



[Jepson (F. p.).] Investigations into Shot-hole Borer of Tea. — Trop. 

 Agric, Peradeniya, lix, no. 1, July 1922, pp. 24-27. 



From manurial experiments it has been found that sulphate of 

 ammonia and nitrate of soda and, to a less extent, lime have had 

 some beneficial effect in reducing attacks of the shot-hole borer of tea 

 [Xyleborus fornicahis]. A second series of experiments was begun 

 to ascertain the effects of a good general manure mixture at varying 

 rates per acre and whether liberal manuring in any way promoted 

 the progress of the healing of gallery-entrances. These are described 

 and are still in progress. It is suggested that further experiments 

 with individual manures should be commenced as soon as possible 

 to confirm the results obtained.

This issue is larger than that of the preceding year [R.A.E., A, ix, 

 445] owing to the increased number of foreign periodicals available. 

 The German periodicals numbered about 180, practically all the 

 German literature of importance, especially on the agricultural side, 

 being noticed.

Attention is called to the fact that the correct name of the ro.se 

 weevil known as Pantomorus fulleri, Horn, is P. godmani, Crotch.
