4 Second Report on Economic Zoology. 
Numerous correspondents have written for information concerning 
these pests ; some of their letters and the reports sent to them are 
here reproduced. 
One personal visit has been made privately to Higham Hall, 
the seat of Lady Henry Somerset, on the borders of Epping Forest, 
and others by Mr. Lowe, who has been employed by her ladyship to 
superintend the treatment of the pools, tanks, etc., in which the 
mosquitoes were found to be breeding. 
As a rule, Anopheles maculipennis and A. bifurcatus are in grea.t 
abundance in the valley of the Stour, in Kent, but this year they 
have been comparatively scarce ; Culex pipiens and Theobaldia 
annulata , on the other hand, have been present in great numbers, and 
have bred much more rapidly than usual. Although the latter 
species has been the cause of much annoyance elsewhere (vide letters 
re mosquitoes at Weston-super-Mare), it has not been found to bite 
in the Stour Valley, neither is any annoyance caused by Culex 
pipiens in that region. 
Undoubtedly the most vicious biters have been Thxobaldia 
annulata, Culex nemorosus, Culex diversus, Culex morsitans , and 
Grabhamia dorsalis. 
In woodland districts of East Kent, Culex cantans, Meigen, bites 
very ravenously at dusk, especially on the ankles. 
I. Mosquito annoyance at Woodford and Epping 
Forest. 
Towards the end of May, Lady Henry Somerset wrote from 
Higham Hall, Woodford Green, Essex, asking how to deal with the 
enormous increase of mosquitoes in that neighbourhood. 
In a subsequent communication she stated that : — 
“ The cold weather seems to have driven them in, and I have not 
seen a single one to-day, but if I possibly can I will endeavour to 
procure one or two. They are large and extremely poisonous — so much 
so, that almost everybody who is stung here have their limbs swollen, and 
it is exceedingly painful and disfiguring. At the bottom of the meadow, 
probably a quarter of a mile away, there is a large lake. Of course they 
may breed there ; I do not know.” 
On the following day a large mosquito was sent, which proved to 
be Culex diversus, Theobald. 
On the 12th of June I paid a private visit to Higham Hall and 
the surrounding area, including part of Epping Forest, which sur- 
rounds part of the estate, and in consequence sent the following 
report to Lady Henry Somerset : —
