pinpointed the major focus of these mosquitoes to have been in the Ilonouliuli 
area on the Ewa side of Fearl Harbor. The closest point to Hawaii where this 
mosquito is known to occur is some 2,000 miles away. Therefore it is believed 
that dispersion from its point of origin was by human means (probably by 
aircraft’) and not by natural means. The most likely points of origin, in 
order, are as follows: Guam, Fiji, or Samoa. 
On April 5> 1962 one female specimen was taken in a light trap at Kapaa, 
Kami. Larval breeding was found to be principally confined to the Coco Palms 
area. The dispersion from Oahu to Kauai (a distance of 70 miles between 
closest points) is believed to have been by natural means. 
The following table shows the mosquitoes present on each of the eight 
islands which constitute the Hawaiian chain:
