Mosquito Annoyance at Blacklieath. 57 



I know of no records of mosquitoes from either Greenwich Park or 

 Blackheath. Two species occur in abundance in some of the docks 

 (London and Albert), namely, Culexjnpiens, L., and Cuhx (lorsaUs,M.Q\gQn, 

 and from the latter dock I have received Culex pukritarsis, of Rondani, 

 Cidex dorsaUs is a vicious biter, and I believe occurs all down the river. 

 Cidex pipiens also bites severely at times, the bites being followed by large 

 red oedematous patches. I am afraid without investigation on the spot I 

 cannot possibly help you further.
