females — flying about and settling on the stems of plants and inserting 
their proboscides, apparently engaged in sucking. The two plants 
attacked were the periwinkle ( V. major) and young wallflowers." 
Dr. Hatchett Jackson adds: — "Most people at Weston are well 
acquainted with this species owing to its speckled wings, and it is 
usually to be met with in autumn in the woods on Worlebury Hill 
behind Weston on the north. Indeed it is sometimes spoken of as 
the ' Wood Gnat.' " In November, 1904, reports and specimens 
received from Leamington, Warwickshire, and Sleaford, Lincolnshire, 
showed that this species was again troublesome in different parts of the 
country. 
The geographical range of T. anmilata is very wide, for, besides 
being distributed throughout Europe, the insect also occurs in the 
Punjab, India, while in America it is found from Canada to Mexico.

In the British Islands this gnat is apparently less common than 
some other species, and the only British specimens at present 
contained in the Museum collection are from Merton Hall, Thetford, 
Norfolk, June 10th, 1900 {Lord WalsingJiani) ; Cambridge (F. V. 
Theobald) ; Ledbury, Herefordshire, June 2nd, 1895 (Lieut.-Colonel 
Yerbury); Ashford, Kent, August 12th, 1902 (W. R. Jeffreys) ; and 
Brockenhurst, New Forest, Hants, May 5th to 19th, 1904, and 6th to 
1 2th, 1905 (C. O. Waterhouse). Theobald writes (op. tit., Vol. III. 
O903), p. 179): — " C. cantans is a sylvan species, which Mr. W. R. 
Jeffreys, of Ashford, assures me is vicious in the woods in the Weald 
of Kent. It bites at dusk, especially choosing the ankles." 
This species occurs throughout Europe, and is also found in 
India and Canada.
