PACIFIC SCIENCE, VoL VII, July, 1953 
to the same ecological niche as Culex sitiens 
Wiedemann, 1828, another species with short 
hair 1-C and stubby anal gills, characters ap- 
parently associated with a brackish-water habi- 
tat. The only other species found associated 
with U. atra on Guadalcanal was Anopheles 
farauti Laveran, 1902. 
Living larvae are paler than those of other 
species inhabiting ground pools and can be 
immediately recognized in the field by the 
extremely short anal gills. The pupae are easi- 
ly recognized in the field by the entirely dark, 
very elongate slender trumpets. 
This species has been reported breeding in 
crab holes and stagnant pools or swamps with 
nipa palms in Malaya (Leicester, 1908: 
217), in brackish water on a coral islet in 
Java (Brug, 1924; 442), and in forest streams 
in the Philippines (Baisas, 1935: 65). 
The adults of this species were not collected 
on Guadalcanal and there is no published 
account of their habits.
