clearly defined, properly known, British species of this genus. As 

 the works in which they are described are none of them English, and 

 some of them difBcult of access, it may be worth while giving a table 

 and short description of them here. They may bo arranged as 

 follows : — 



Spenies with yellow femora and tibiae vulfinus, Fin. 



Species with black legs (tibiae sometimes brownish) A. 



A. Species with bright reddish middle streak on irons... comptus (Fall.), Rdi. 

 Species with black middle streak on frons B. 



B. Species with 7 bristles on 3rd longitudinal vein near base ; with bristly 

 genae ; and with reddish genitalia in male. . .hfenwrrJioidali.s (Fall.), Rdi. 



Species with 13 bristles on 3rd longitudinal vein near base ; with fine hairs 

 only on genae; and with black genitalia in male pudicun, Rdi. 



Vulpiniis is the commonest of these species. I have seen it in 

 thousands in Wyre Forest, Worcestershire ; Col. Yerbury found it 

 commonly in the north of Scotland last year, and I have taken it or 

 seen it from Cornwall, Norfolk, and various intermediate localities, 

 and believe it to be generally distributed. It is unmistakeable, its 

 yellow legs and the general yellow effect of the insect proclaiming 

 it at once. 



Gomptus I do not know. I believe it to be very rare. Mr. Austen 

 records two specimens only in the British Museum collection from 

 localities as far apart as Cromarty and Surrey (Ent. Mo. Mag., 1898, 

 p. 38). Meade and F. Walker both say rare, without giving localities, 

 and I have never come across it myself. It should be readily dis- 

 tinguished by its bright red or yellow central streak to the frons, in 

 this respect resembling vulpimis, from which, however, its black legs and 

 much darker appearance would at once separate it. Brauer and von 

 Bergenstamm say that it has orbital bristles in the male sex (Die 

 Zweifliigler des Kaiserl. Museums zu Wien, iv, p. 65) ; Meade (Ent. 

 Mo. Mag., 1891, p. 91) says it has not even hairs on the genae, which 

 would be a good character, if true, as vulpinus sxud pudicus have abund- 

 ance of fine long hairs, and hfsmorrlwidalis has bristles. This species 

 was known asfulffens, Mg., by Schiner, Walker, and Meade, and was 

 so called in Verrall's first list ; it seems now, however, to be considered 

 identical with compfus, Fall., and is certainly the same that Eondani 

 recognised as that species. Fallen spelt it covita by the bye, so that 

 some choice of names is open to us. 



Pudicus is apparently not uncommon in the south, as I have it 

 from Colchester, Bexley, Farniiigham, and Lamorbey, and Austen
