enemy of the Colorado potato beetle which appeared in western 

 France after the World War. 



A long paper has just been ])uljlishcd l)y Doctor Marchal giving a 

 full account of the history of the Aphclinus uiali introductions and 

 giving an accovmt of the insect's biology in France and its status as 

 an enemy of the woolly root-louse. It seems now to be a permanent 

 resident in France. 



GREECE 



Novius cardinalis was introduced into Greece to prey upon Iccrya 

 piirchasi, and in March of 1928 A. Ayoutantis reported that it was 

 then established in two centers near Athens. 



GUAM 



Numerous attempts have been made to bring in parasites of 

 injurious insects into Guam by S. R. Vandenberg. Three of these 

 introductions were very successful, namely Novius cardinalis for the 

 cottony cushion scale, Cryptolaemns inontrousieri for mealy-bugs, 

 and the Tachinid, Ceromasia sphenophori, for the sugar cane beetle 

 borer. An attempt was made to establish the Coccinellid, Lindorus 

 lopanthae, but without success ; and attempts made to establish 

 Compericlla bifasciafa from California on the red scale were also 

 unsuccessful. 



HAWAII 



Some of the most extraordinarily successful work that has been 

 done in the introduction of parasites and natural enemies has been 

 carried on in the Hawaiian Islands. There is a list of these introduc- 

 tions down to 1923 in an article by O. H. Swezey on pages 299 to 304 

 of the Proceedings of the Hawaiian Entomological Society, Volume 5. 

 Supplementary to this list, Mr. Swezey published in the Journal of 

 Economic Entomology, Volume 19, October, 1926, a paper entitled 

 " Recent Introductions of Beneficial Insects into Hawaii," pp. 715- 

 720. The number of these parasite introductions proving successful 

 is astonishingly large. It has been pointed out repeatedly that the 

 equable climate of the Hawaiian Archipelago and the fact that it is 

 composed of islands makes success reasonably sure in experiments of 

 this kind, or at all events these conditions offer much better chances 

 for success than a continental region in a more northern or southern 

 location. However, not all of these importations have been striking 

 successes. The Hawaiian work has been written up a number of times 

 by other investigators, but it has never been better done than by
