Genus BIRONELLA Theobald 
Since only two species of this genus have 
been completely described in the pupal stage 
it is impossible at the present time to formulate 
a diagnosis of the genus which will successfully 
separate it from Anopheles. Bironella ( Bru - 
gella) hollandi Taylor is of doubtful occurrence 
in New Guinea; its pupa was completely fig- 
ured and described by Belkin, Knight, and 
Rozeboom (1945: 244). 
Bironella (Bironella) soesiloi sensu Swellen- 
grebel and Rodenwaldt 1932, as designated 
by Leeand Woodhill (1944: 65)
