Notes on Life-history and habits. 



Recent observations have shown that this large mosquito is 

 a very vicious biter in this country. One correspondent, Mr. W. 

 Hatchett Jackson, D.Sc, stated that " the consequence of its bite 

 may be so severe indeed that the patient has to go to bed." This 

 gentleman informed me that " it usually occurs in the flat country 

 round Weston-super-Mare in large numbers in September and 

 October, but only invades Weston itself to any appreciable extent 

 when the wind blows from the plains, that is to say, between N.E. 

 and S. It has been relatively rare round Weston and on the 

 Glastonbury Plain the last few years owing to the ponds and 

 wet dividing ditches, known in Somerset as rhines, being dry or

 it has been a veritable plague. Hence few persons in Weston 

 and its neighbourhood have escaped the attack of this gnat. The 

 consequence of its puncture may take one of three distinct lines :
