 2 plates. 



The Chrysomelid, Phytorus dilatatus, Jac, which has been recorded 

 from tea in Sumatra in the past, but not as of economic importance, 

 did sufficient damage to tea in 1921 to warrant close attention being 

 paid to it. In one instance the infestation began on cabbage and 

 spread to yams and then to tea, when the yam leaves had reached 

 full growth. P. dilatatus has also been seen on a Composite and on 

 Mallotus philippinensis, a wild plant. The young leaves of infested 

 tea plants were eaten, and many plants had the broom-like appearance 

 characteristic of red rust. The base of the young twigs was also 

 eaten. P. dilatatus has not yet been found on tea in Java, but 

 according to Corporaal it has been observed in Western Java on 

 various plants near a tea estate.

This is a record of an accidental infestation of tea by a Pierid 

 butterfly, Delias belisania. Cram. It is not a normal pest of tea, and 

 is, indeed, usually beneficial, as it lives on a parasitic mistletoe, 

 Loranthus sp. «

 Snoei ? [Is there a Connection between Helopeltis and Pruning ?] 

 — De Thee, Buitenzorg, ii, no. 4, December 1921, p. 121. 



The attention of tea planters is drawn to the necessity for recording 

 observations regarding pruning and the occurrence of Helopeltis, both 

 as regards the different methods adopted and the date at which this 

 work is done.

 considerable damage to apple trees and hawthorn. A description of 

 it is given.
