Specimens examined. — The pupal exuviae 
of seven males and four females from Hilimoi, 
Milne Bay, Papua. 
Subgenus GEOSKUSEA Edwards 
None of the four species assigned to Geo- 
skusea has been described in the pupal stage. 
Only one species has been recorded from New^ 
Guinea. 
Subgenus STEGOMYIA Theobald 
Diagnosis. — Although many of the species 
of this subgenus have been described in the pu- 
pal stage, Stegomyia is rather hard to separate 
definitely from all other subgenera in the New 
Guinea area. Edwards (1941: 387) used the 
position of the dorsal seta (8) of the cephalo- 
thorax as diagnostic, but this is a relative char- 
acter which is encroached upon by certain spe- 
cies of other subgenera. For the most part, how- 
ever, species of Stegomyia may be distinguished 
by having the dorsal seta placed well behind the 
bases of the trumpets, i.e., at least halfway be- 
tween the trumpets and the anterior margin of 
the metanotum, instead of between them or
