mer became a teacher for a time, and in 191 8 became Director of the 

 Botanical Garden in Buitenzorg. In 191 1 Doctor Roepke took charge 

 of the experiment station in Salatiga. In 1914 Dr. P. van der Goot 

 became his assistant and served until 191 7. Doctor Roepke resigned 

 his position in 1918, on account of his health, but worked in Buiten- 

 zorg until 1919 at the Phytopathological Institute. Later he accepted 

 a position as Professor of Tropical Agriculture in Wageningen, and 

 still later became Professor of Entomology there. 



The Tobacco Planters' Experiment Station at Deli did perhaps 

 more entomological work than the other stations. L. P. de Bussy was 

 the first" Entomologist and served from 1907 to 19 17. Later he 

 entered the service of the Colonial Institute in Amsterdam and also 

 became professor in Utrecht where he gives lectures on tropical 

 agriculture. J. den Doop, C. J. van der Meer Mohr and Doctor 

 Fulmek also did some entomological work at Deli. 



Dr. J. D. Corporaal for a few years worked as Entomologist to the 

 Rubber Experiment Station in Medan and is at present Curator in the 

 Zoological Museum at Amsterdam. 



The Tea Experiment Station at Buitenzorg did much entomologi- 

 cal work. Dr. R. Menzel, a Swiss, worked as Entomologist from 

 1918 to 1928. He returned to Switzerland and is at present Director 

 of the Experiment Station for Fruit and V'me Culture in Wadenswyl. 



H. Jensen, a Dane, also worked on toljacco insects in Java until 

 about 191 7, and the botanists Wurth and P. Arens did some work on 

 entomology while at the Coffee Experiment Station in ]\Ialang. Dr. 

 11. Begcman, of Utrecht, was appointed Entomologist at this Sta- 

 tion and worked from 1925 to 1929 exclusively on coffee insects. He 

 was succeeded l)y Dr. J. G. Betrem, of Wageningen, an assistant to 

 Doctor Roepke. 



During the war, Stcphanodercs hampci became a great coffee pest. 

 It had been noticed in West Java as early as 1909, but did not become 

 prominent until a number of years later. In 1922 the coffee planters 

 established a fund and sent J. den Doop to Uganda to search for para- 

 sites. He introduced two — the one a Braconid (Hcicrospilus coffei- 

 cola Schmiedeknecht) and the other a Chalcidid (Prorops nasuta 

 Waterston). The latter species met with some slight success, but so 

 far has not checked the pest. In 1922 Dr. K. Friederichs, the German 

 entomologist, who had worked in Samoa, took charge of the coffee- 

 beetle work and remained in Malang until 1924 when he returned to 

 Germany [where he has done the excellent work at Rostock mem- 

 tioned elsewhere].
