ABSTRACT. Observations on blood-feeding in nature, and precipitin tests on engorged females, have been made on mosquitoes, Cedes inzpiger and A. nigApes, occurring near Lake Hazen, S.K.T. 161”49’5., il”ls’n’.:l. Terrestrial vertebrates recorded from the area are listed. Both species of mosquitoes obtain blood in nature from musk oxen and birds (also humans); several specimens contained blood of tEo kinds (precipitin test determinations). Host reaction to harassment by mosquitoes is evidently a major factor determining n-hich potential hosts are fed on successfully. On the basis of their behaviour and situation, musk oxen, and birds nesting in xva.ter-logged sites are deemed the most likely animals to provide blood. I\lethocls for determining host preferences in the Arctic are briefly discussed. Rl%L~3IIT,. Les HBfes ~2ntzrrel.5 des ii2o2@2tes dons le nerd de We cl’Ellesmere. P&s du lac Hazert, T. du S.-O.
