LIST OF THE ANOPHELINES OF THE MALAY ARCHIPELAGO.

3. Myzomyia rossii. 



Christophers (1916) states that M. rossii, Giles, is the common western form, 

 whilst M. vaga, Don. {indefinita, Liidl.) occurs throughout Malaya. To this should 

 be added that M. rossii does so likewise, as far as the Moluccas ; only in Sumatra 

 it has not been found, up till now. 



4. Myzomyia ludlowi and Myzorhynchus sinensis. 



We failed to find botli species east of Celebes. But we know that in districts 

 where M. ludlowi usually is of common occurrence, it may be absent for months 

 and even for a whole year (Citroen 1917). As suitable breeding places were present, 

 hkewise its common sateUite M. rossii, we are not sure that M. ludlowi is really 

 absent from the Austrahan regions of the Archipelago. 



5. Stethomyia aitkenii 



The form with the typical larvae — including all variations described by Stanton 

 (1915) and Stickland (1915) — was not found in the Austrahan region of the Archi- 

 pelago. The species was represented there by the varieties insulae-florum and 

 papiiae, which in their turn were absent from the western regions, except var. 

 insulae-flormn, which occurs on the south coast of Java (Island of Noesa Kembangan). 



The following table gives a summary of our present knowledge of the distribution 

 of the Anophehnes in the Malay Archipelago.
