(yellow tea mite) was reported near Buitenzorg. Owing to the wet 

 east monsoon, Brevipalpus ohovatus (orange tea mite), Eriophyes 

 {Phyloplus) carinatus (purple tea mite) and other mites did but little 

 damage.

Circular no. 28 of 4th December 1916, issued by the Deli Experiment 

 Station, draws attention to the fact that coriander {Coriandrum 

 sativum) and caraway {Carum carui) are very attractive to Lasioderma 

 serricorne and should be inspected as well as tobacco.

Circular no. 30 of 18th February 1917, issued by the Deli Experiment 

 Station, emphasises the necessity of removing and burning wild tobacco, 

 as Phthorimaea opercnleUa {Lifa solamlla) has never been found in 

 Deli except on tobacco and therefore evidently lives on wild tobacco 

 when the cultivated plants are not available.

As a large portion of the 1916 Sumatran tobacco crop will have to 

 be stored some months before shipment, precautions must be taken 

 against Lasioderma serricorne and the tobacco moth [?]. 

 Great vigilance is needed in watching that these pests are absent from 

 the fermenting sheds or other parts of the factory. The bales must 

 be well covered up and turned once a month, when a couple out of 

 every hundred must be most carefully examined, special attention 

 being paid to the tobacco at places which have been in contact with 

 seams in the covering. Wide-mouthed bottles containing tobacco 

 leaves or cigars should be placed in various parts of the sheds 

 as traps and must be inspected once monthly. A couple of drums of 

 carbon bisulphide should always be kept in stock for immediate use if 

 necessary.
