PACIFIC SCIENCE, Vol. V, October, 1951 
palpis? to the list for Milne Bay. 
3. Four species of Anopheles {farauti, punc- 
tulatus, bancrofti pseudoharhirostris, longirostris) 
are recorded. Bancrofti and longirostris were 
rare; the former was found only at Saidor and 
the latter only at Milne Bay. Farauti and 
punctulatus were common to extremely abun- 
dant in nearly every area. Because of their 
abundance and widespread distribution it 
seems that only these could be significant 
malaria vectors in New Guinea. 
4. Aedes scutellaris was the only species com- 
mon in every locality. Because of its abun- 
dance and widespread distribution, and con- 
sidering the results of transmission experi- 
ments, this species is of considerably greater 
significance as a dengue vector than all other 
culicines. 
5. Aedes albopictus, so frequently reported as 
common, was not recorded. Culex fatigans 
was found only in a single collection from 
the Padaido Islands. Aedes aegypti was repre- 
sented by a single adult collection from 
Samarai Island. 
6. Based on distribution and numerical 
abundance, C. pullus, C. halifaxi, A. albo- 
lineatus, and A. notoscriptus are potentially im- 
portant pest species along the north coast. 
However, practically nothing on their biting 
habits has been recorded. In particular areas 
other species may assume local importance, 
as Armigeres milnensis, which was exception- 
ally abundant at Milne Bay, and Culex sitiens 
at Amsterdam Island.
