has been called conterminous : it exhibits to us affinities ex- 

 isting in nature by which we are enabled to approach nearer 

 to a natural arrangement. It differs from Tipula in having 

 only 12 joints in the antennae, and a few scattered bristles 

 upon them, instead of 1 3 joints ornamented with whorls of 

 hairs ; from Limnobia it differs in the length of the terminal 

 joint of the palpus, and the long cylindric joints of the an- 

 tennae; but the most decided and remarkable characters which 

 at once distinguish it from both these genera are the absence 

 of the 3rd discoidal cell, which in them is never wanting, 

 various as the wings of these genera are, and the extraordinary 

 length of the basal joints of the tarsi, which are all very much 

 longer than the tibia? : — to this circumstance the generic name 

 that I have adopted refers. 



In my ramble through the New Forest the beginning of 

 last June, in a part that lies rather low and was at that time 

 swampy from springs that appeared to rise there, upon the 

 mossy trunk of one of the magnificent beech-trees that orna- 

 ment the neighbourhood of Lyndhurst I saw many of both 

 sexes of this elegant insect ; they rested as represented in the 

 plate with their wings spread, and although it was a fine calm 

 morning, their hinder legs, which did not touch the tree, waved 

 backward and forward, as if the least touch would disjoint 

 them : the trunk was so much overshadowl^d that had it not 

 been for the white feet of the insects, which rendered them 

 conspicuous, they would have escaped my observation; and it 

 is a little singular that although this was on my first arrival, 

 and I stayed some time in that neighbourhood, I never saw 

 any more of them. Upon looking over Mr. Stephens's cabinet 

 I found one female which he had always considered as being 

 different to other described genera, neither does it appear, as 

 a species, to have been before noticed. 



Polygala vulgaris (Milkwort), which was in flower at the 

 time netu' the spot, is figured with the insect.
