THE MOSQUITO

Whether other Anophelinse are efficient has not been determined. So far no other Culicidæ have been found to foster the malaria parasites of man, and experiments with Culex albopunctatus, C. penicillaris, C. vexans, C. pulchritarsis, C. pipiens, Tœniorhynchus richiardii, Theobaldinella annulata, and T. nemorosa have proved negative. Considering that Culex pipiens transmits several Hæmoprotozoa of birds, closely allied to those of men, it would be rash to assert positively that the Anophelinæ are the only mosquitoes which transmit the malaria parasite.
