places in a drying-out teatree swamp a few yards from 
the river bank. Another biting species which attracted 
attention by its size rather than its numbers was the 
"Scotch Grey." Aides ( ,1/ ueJdus) alternans. 
In a steep-sided rocky gully where a smrll fresh water 
creek flows on to the northern end of Xoosa Beach, a 
variety of species was biting. In addition to these mention- 
ed above, Aides similis, Aedes ntbrithornx, Aides kochi, 
Tueniorhynchus uni) or mis, Culex situ us, Ciihx annuliro - 
stris and ('ulex sp. (near eylind virus) were collected. 
Larvae of Aedes kochi were found in water in tin* leaf-axils 
of Pitnduints growing along the sides i f this gully. These 
larvae are clothed with stiff many-branelied stellate hairs 
which enable them to crawl for considerable distances over 
a moist surface, thi s ensuring their survival when some of 
the axils dry out. The adult is orn: mealed with black and 
wnite bairns and spots on prob seis, legs and wings. It is 
a common pest species in New Guinea and New Britain, 
where it has been proved an efficient vector of filariasis. 
Though numerous Pimdonus plants were examined along 
the he. dlands and elsewhere, this was the only site where 
larvae of kochi were found. 
In the swamp at the northern end of Noosa Beach a 
single specimen of Aides lineatopennis was taken biting. 
This dark species is readily recognised by the bright, deep 
yellow bands on either side of the thorax which meet in a 
V on the head. Though rarely more than an occasional 
specimen is met with in South Queensland, this species has 
a wide distribution through the Philippines, Malaya. India 
and Africa, in cue or two puddles along the edge of the 
same swamp, larvae of Anopheles cnniilipes were found. 
These also occurred in a pool a little farther inland where 
they were associated with those of V ranotaenin pyg.maea 
and Cule.r sp. (near eylind ricus) . 
Larvae of Aedes multiplex were collected from pools 
in t lie teatree swamps on the banks of the Noosa River. 
Adults of this species are occasionally caught biting, but 
the lrrva, which is still undescribed, is very rarely found. 
Males reared from these larvae were of particular interest, 
as hitherto there were none available for study in collec- 
tions in Queensland.
