In common with all species of Tripteroides 
in our collections, T. hrevipalpis? was limited 
entirely to small collections of water in con- 
tainers. It was found primarily (88 per cent) 
in mixed collections. Percentages of associ- 
ates were: A. scute liar is, 27; A. albolineatus, 
27; C. Puniformis, 20; U.papua, 14. 
Harpagomyia genurostris (Leicester) 
Malaya genurostris Leicester, 1908, Cul. Mala- 
ya: 258. 
DISTRIBUTION: Northeast New Guinea: 
Saidor (Author); Alexishafen (T. K. Rue- 
bush). Papua: Dobodura, Cape Sudest (King, 
1944) . Aside from the mimeographed records 
of King (1944), these are the first New Guinea 
records of this Oriental species. 
HABITAT: Brug (1932) recorded larvae from 
the leaf axils of Colocasia spp., Crinum sp., 
Susum malayanum aquatica, and from the in- 
florescence of Cyrtandra glabra. King (1944) 
reported it from the leaf axil of taro {Colo- 
casia sp.). 
All of my eight collections were taken from 
leaf axils (taro, 63 per cent; banana, 37 per 
cent), in clear, shaded water. This species and 
Aedes kochi were the only larvae with an abso- 
lute affinity for any one habitat. Harpagomyia 
genurostris was found associated with A. 
kochi once; otherwise it occurred in pure 
collections. 
Uranotaenia (Uranotaenia) albescens 
Taylor 
Uranotaenia albescens Taylor, 1914, Ent. Soc. 
London, Trans. 1913 (Part IV): 705. 
DISTRIBUTION: Papua: Milne Bay (Lee, 
1944^; Author). 
HABITAT: All New Guinea records are from 
surface water. Taylor {1914c) recorded it from 
clear, shallow, grassy pools, and Lee (1944^) 
added wheel ruts. My single collection was 
taken from a clear, sluggish, exposed running 
creek with abundant emergent vegetation, at 
a pH of 5, and associated with Anopheles 
farauti. 
Uranotaenia (Uranotaenia) argyrotarsis 
Leicester 
Uranotaenia argyrotarsis Leicester, 1908, Cul. 
Malaya: 214. 
Uranotaenia argyrotarsis var. King and Hoog- 
straal (1946/: 148). 
DISTRIBUTION: Dutch New Guinea: Hol- 
landia (King and Hoogstraal, 1946/). North- 
east New Guinea: Finschhafen, Saidor (Au- 
thor). Papua: Milne Bay (Author).
