King, 1947; Forbes and Horsfall, 1947); Biak 
(Forbes and Horsfall, 1947) ; Padaido Islands, 
Amsterdam Island (Penn, 1947^; Author). 
Northeast New Guinea: Seleo, Berlinhafen, 
Astrolabe Bay, Bogadjim, Muina (Theobald, 
1905); Lakekamu Gold Field (Taylor, 1914^; 
Breinl, 1915); Madang (Hill, 1925); Wau,

Saidor (Farner and Bohart, 1945; Penn, 
1947 ^; Author); Draeger Harbor (Penn,

fall, 1947 ); Moresby (Hill, 1925; Mackerras,

Taylor (1914^) and Breinl (1915) recorded 
Stegomyia pseudoscutellaris Theobald from 
Samarai Island, Papua. This record probably 
refers to A. scutellaris^ since this locality would 
extend the range of pseudoscutellaris— 2 iS de- 
fined by Farner and Bohart (1945) — several 
thousand miles westward.

Along with A. albolineatus, scutellaris was 
present in my collections in every area studied, 
and ranked second only to C.pullus in number 
of collections. 
Brief mention of habitats utilized has been 
given by Hill (1925), Bonne-Wepster and 
Brug (1932, 1937, 1939), Taylor (1934), Lee 
( 1944 ^), Farner and Bohart (1945), and King 
and Hoogstraal (1946c). Tree holes, coconut 
shells, and artificial containers are the habitats 
most commonly recorded, but fallen leaves, 
forest pools, and rock holes have also been 
mentioned. 
After its role as a dengue vector was estab- 
lished (Daggy, 1945 ; Mackerras, 1946) rather
