species^ collected in the areas of study. When 
the same locality is repeated by several 
authors, each reference is included. All type 
localities in New Guinea are given, but addi- 
tional references to this locality are not re- 
peated. Latitude and longitude for nearly 
every locality may be found in the U. S. Army 
Map Service Gazetteer to Maps of New Guinea 
(1943). 
A great variety of spellings of the various 
place names was encountered. Moreover, 
many of the German names employed in 
Northeast New Guinea were changed after 
the area became an Australian mandate. To 
2 In the thesis on which this paper is based (de- 
posited in the library of Cornell University) I have 
listed all distribution records of the 179 species ever 
recorded from New Guinea as well as my own distri- 
bution records for the 47 species discussed in this 
paper. In addition, all literature on the ecology of the 
larvae of each of the 179 species was summarized and 
compared with my own numerical data. However, for 
the sake of brevity, this paper deals primarily with 
distribution and ecological data for the 47 species I 
personally encountered.

Collecting Technique 'i 
Each collection was a sample from a par- , 
ticular microhabitat at a particular time. Each 
microhabitat usually presented at least one l! 
distinguishing characteristic, even when sev- 
eral of them were located in temporary water | 
in close proximity. A single macrohabitat :i 
often included a large number of micro- | 
habitats in a very limited horizontal range, j’ 
For example, in certain cases the superficial || 
picture may have been of a definite marsh, | 
yet separate collections could be made from ii 
puddles, artificial containers, coconut shells, I 
etc., through a great range of microhabitats. !| 
As a result of sanitary control operations, re- I 
peat collections from the same microhabitat | 
were seldom possible. i 
All ecological data were recorded in the : 
field, using for each collection a 3X5 index J 
card whereon space was provided in the cen- | 
ter for recording the locality, date, time, and -
