the parasite had passed through i6 generations and had muItipHed in 

 the open. During the same year a report was pubHshed by W. Roepke 

 stating that the first attempts to get parasitized eggs from America 

 in good condition failed, but that an intermediate breeding station 

 was estabHshed in Holland. Moreover, the first lot from America 

 gave out only male parasites ; later ones, however, produced females 

 that were sent on to Sumatra. 



For some years I noticed no reports on the later results of this 

 introduction. In 1918, however, J. E. A. den Doop published an 

 article in the records of the Experiment Station at Deli, Sumatra, in 

 which he stated that he had been investigating the subject under field 

 conditions since 19 16. He found the parasites existing in numbers 

 and attacking the eggs of a large number of injurious moths. He 

 concluded that T. minutmn could be used against Hcliothis ohsoleta 

 and also perhaps against Plusia, but not against Prodenia, Phthori- 

 maea, and Botys. 



In 1924, S. Leefmans reported the importation of parasites of the 

 coffee berry borer from Uganda into the Dutch East Indies. One of 

 these parasites was believed to be a Bethylid, Prorops nasuta. 



The question of native parasites had been studied years before by 

 L. Zehntner. 



EGYPT 



Noviiis cardinalis was introduced into Egypt from the United 

 'States in 1892. It was sent to Alexandria tO' feed on Icerya 

 aegyptiacum. 



Of recent years, Microhracon kirkpatricki was introduced from 

 Kenya, where it is an efficient parasite of the pink boll worm, into 

 Egypt, according to A. Alfieri writing in 1929. 



FIJI 



In 1913, F. P. Jepson, then Government Entomologist of Fiji, 

 transported 5,000 Histerid beetles {Placsius javanus) to Fiji from 

 Java, as it was an important enemy of the banana weevil (Cosinopo- 

 liiies sorditus) . Twelve hundred perished on the way, and 3,500 were 

 distributed in lots of 500 on seven different plantations. I have not 

 learned the subsequent history of this introduction. 



In 1913, the Tachinid fly, Ceromasia sphcnophori, that had done 

 excellent work against the sugar cane borer in Hawaii, was intro- 

 duced into Fiji by J. F. Illingworth. A thousand parasitized grubs 

 were carried over. It was found that only a strong colony could with- 

 stand the losses caused in the field by predatory enemies, notably ants 

 and spiders.
