•of the scales in the adult of this mosquito. One form, A. amictus, 

 Edw., has recently been given specific rank. 



A. barbirostris , Wulp, var. bancrofti, Giles, is apparently confined 

 to the coastal districts of Queensland and of the Northern Territory. 

 The larvae are found practically wherever there are fresh-water 

 swamps or sluggish streams with more or less luxuriant vegetation, 

 and they are frequently associated with A. annulipes. It is rare in 

 houses, except in the vicinity of jungle or swamp. Horses, cattle, 

 buffalos, kangaroos and birds are probably the normal hosts. 



Aedes {Stegomyia) albopictus, Skuse, has not been recorded in 

 Australia since its discovery in 1913, though individuals have been 

 received from Moa Island (Torres Straits). A. argenteus, Poir. 

 {Stegomyia fasciata, F.) is the most abundant and troublesome species 

 in Townsville. It is found throughout the year and is often present 

 in dwellings, biting generally by day. Culex fatigans, Wied., is also 

 abundant and annoying in houses, feeding always by night. Larvae 

 are numerous in fresh-water tanks, yard drains and any collections 

 of water in domestic receptacles about houses. Ae.les [Ochlerotatus) 

 vigilax, Skuse, is widely distributed along the coastal districts 

 and probably to a large extent inland. It is most abundant in 

 mangrove swamps, tidal creeks and the neighbouring scrub. It is 

 believed that the adults fly as far as four miles or more from their 

 breeding-places to the towns. A. (0.) notoscriptus, Skuse, is widely- 

 distributed and is found in numbers locally, breeding in rot-holes, 

 pools in fallen tree-trunks, etc. It is abundant through the greater 

 part of the year. Aeies {Skusea) funeveus, Theo., is often found in 

 habitats similar to those of A. notoscriptus, and is frequently in 

 association with it and also with A. (0.) qnasinibrithorax, Theo.

 In order to determine the importance of certain variable factors 

 in individuals, regarded as hosts of the mosquito, Aeies [Stegomyia) 

 argenteus (calopus), feeding experiments were undertaken and records 

 made of the results under the headings of length of residence in Brazil, 

 sweating and hairiness of skin surface, coloration, age and nationality. 

 The number of individuals tested (88) and the number of bites (619) 

 were too small to admit of definite conclusions, but the figures suggest 

 that none of these factors has any marked influence on the number of 

 bites received. There is probably, however, a greater local reaction 

 immunity displayed by the native, and to a less extent, by the old 

 resident, than by the newcomer.
