196 [August, 1905. 



1. T. spinigerellus Zett. : I have numerous records from Hampshire 



to Cambs., but I have never met with it in abundance. 



2. T. ononacanilnis Lw. : one male at Wisbech on July 14th, 1881, 



and another at Lyndhurst on July 17th, 1887. Neither 

 specimen vi'as recognised until many years after its capture. 



3. T. pectinifer Kow. : so abundant about puddles on paths in 



a small vs^ood near Three Bridfjes in Sussex on July 2Sth, 

 1872, that thirty or forty specimens mifjht be swept up in 

 one stroke of a net. Tt again occurred there and in other 

 small woods in the neighbourhood ten years later. 



4. T. simplex Mik : not very uncommon in the middle glade-way 



of the 40-Acre Wood in Chippenham Fen ; first taken on 

 August 26th, 1894. 



33. SYMPYCNU8 Lw. 



1 (') Legs mainly black 1 . f ?>r j/?m Walk. 



2 (1) Legs mainly yellow. 



3 (4) Front coxre blaekish-grey, at the utmost only just tip yellow... 



2. annulipen Meig. 



4 (3) Front coxae all yellow, or only a small portion of base blackish-grey. 



5 (6) Third joint of hind tarsi with a depressed thorn-like bristle beneath at 



tip; hind femora with a brown streak on upper-side... 



3. spiculatnx Gerst. 



6 (5) Third joint of hind tarsi clothed behind with stiff bristly hairs, like the 



fourth joint; hind femora at most black at tip ...4. xneicoxa Meig. 



1. S. cirripes Walk. : not uncommon in the Lake District and 



at "Braemar. 



2. S. annulipes Meig. : exceedingly common everywhere from Padstow 



to Tongue. 



3. S. spiculntus Gerst. : Mr. E. Jenkinson has taken this new species 



to Britain in some numbers at Cambridge and Old Chesterton 

 from May 17th to August 2nd in 1901-2-3, 



4. N. ceneicoxa Meig. : common in the Lake District and in the 



Scotch Highlands, though I have taken it at Thetford in 

 Suffolk. I very reluctantly accept Meigen's name for this 

 species because he says " Hulfglieder alle schwarzlich " as 

 the name denotes, which would only refer to S. annulipes, 

 and consequently I should prefer to retain Zetterstedt's 

 name of nigritihialis.
