Hyhlaea puera, Cram. It is certain that the yearly destruction of 

 the young leaves by the latter moth must be detrimental to the 

 production of timber, nor can the injury done by C. tectonae be 

 unimportant. Infestation by the locust, Gyrtacanthacris nigricornis, 

 was not observed, the outbreak having ended with the wet weather 

 in 1915 and 1916. In gambir [Uncaria] plantations on the Sumatran 

 east coast, the Capsid, Helopeltis sumatranus, Roepke, was noticed, 

 and experiments showed that this insect attacks tea in preference 

 to gambir [see this Review, Ser. A, vi, p. 38]. Hevea was practically 

 free from insect attack ; one case of infestation with Coptotermes gestroi 

 was reported, while Oecophylla [smaragdina] was often troublesome 

 to workers in rubber plantations. Kapok [Eriodendron anfractuosumi 

 in nurseries was infested by the scale, Pseudococcus (Dactylopius) 

 adonidum. Glycine soya was injured by Agromyza. Cinchona 

 was attacked by Helopeltis antonii and by the mites, Tetranychus 

 telarius (himaculatus) (cassava mite), Tarsonemus translncens and 

 Brevipalpus obovatus ; T. telarius was tbe most injurious of these. 



Coconut pests included a Hispid, the Dynastid, Oryctes [rhinoceros], 

 the Curculionid, Rhynchophorus [ferrugineus], the Pyrahd, Melisso- 

 blapies [rufovenalis], and Brachartona catoxaniha. The last-named 

 moth occurred in a great many districts ; a fairly successful remedy 

 was the removal and burning of infested leaves. 



Cof?ee pests included Plagiolepis longipes ; Coccus (Lecanium) 

 viridis ; Oecophylla [smaragdina] ; the Nematode, Tylenchus cojfeae ; 

 Pseudococcus sp. ; and the coffee beetle, Araecerus sp. Nipa palms 

 on the east coast of Sumatra were attacked by B. catoxantha. Kice 

 was infested by a Cecidonlyid midge ; leaf-eating caterpillars ; the 

 larvae of beetles, apparently Holotrichia helleri and Anomala atro- 

 virens ; the bug, Leptocorisa acuta ; and Hesperid caterpillars. 

 Tobacco was infested by Thrips, Prodenia, Agrotis and Heliothis. 

 Tea pests included Helopeltis, Eriophyes {Phytoptus) carinatus (purple 

 mite), Tarsonemus translucens (yellow mite), Tetranychus telarius and 

 Brevipalpus obovatus. Tephrosia Candida, which is becoming popular 

 as a green manure crop, suffered severely from the Tephrosia beetle 

 {Araecerus fasciculatus). 



The following are some of the timber pests observed : — Zeuzera cojfeae 

 in Toona sinensis and Sivietenia ynahagoni, the latter tree being 

 attacked also by a borer of the genus Heterobostrichus or closely 

 alhed to it. The seeds of various Leguminosae were infested by 

 seed-borers. Those of Acacia leucophloea, A. tomentosa, Albizzia 

 procera and A. lebbekoides were attacked by a small beetle, thought 

 to be a Bruchid, while a larger species, apparently Pachymerus 

 (Caryoborus) gonagra, F., was fovmd in the seeds of Bauhinia malabarica 

 and Acacia tomentosa. Timber was also attacked by a Hepialid 

 root-borer apparently identical with Phassus dumor, Moore.
