The following reply was sent : “ The mosquitoes you send are the 
common European annulata, now the type of a new genus — Theobaldia 
(Neveu-Lemaire). It occurs in America, having recently been found 
there, aud also in India. 
“ Ficalbi is wrong in saying it does not bite. It is one of our 
most annoying and venomous species. It has been abnormally 
abundant this last year and I have had several enquiries concerning 
it. I have taken it all through the winter at home (Kent) in 
numbers.” 
Later Mr. Hatchett Jackson wrote that, “ When last at home at 
Pen Wartha, Weston-super-Mare, I gleaned some interesting facts as 
to the bite of this very venomous species.” Again he gives an 
interesting fact, namely, that c ‘ From September, 1902, to the 
beginning of this year we were terribly bothered by it. In early 
autumn it invaded us in myriads. In a summer-house with glass 
windows I counted 132 $ s on November 8tli, 1902. 
The following notes were drawn up by him regarding this pest 
and are reproduced in toto : — 
Notes on Theobaldia annulata. 
It usually occurs in the flat country round Weston-super-Mare 
in large numbers during September and October, but it only invades 
the town of Weston itself to any appreciable extent when the wind 
blows from the plains, that is to say between N.F. and S. It has 
been relatively rare round Weston and on the Glastonbury Plain the 
last few years owing to the ponds and the wet dividing ditches, 
known in Somerset as rhines, being dry or almost dry in summer. 
In the autumn of the past year (1902) there has been a veritable 
plague ; there was a sufficiency of water in the warm months and a 
prevalence of easterly winds in autumn. Hence few persons in 
Weston and its neighbourhood have escaped the attack of this gnat, 
The consequences of its puncture may take one of three distinct 
lines : — 
(1) It is followed by a simple, hard swelling, which, however, 
rises more slowly and disappears more slowly than the swelling 
caused by any other gnat known to me. It is also larger, and traces 
of it may exist for months, e.g.. in my own case I still have a
