beneath, and the front femora of Loew^s species were described as entirely 

 simple. In our British species the front femora have two or three tiny bristles 

 at the middle beneath, hardly distinguishable from the other pubescence except 

 for the fact that they stand out more at right angles to the femur. Prey has 

 proposed a genus (or subgenus) Sepsidimorpha for this species. 



* Sepsis orthocnemis, Frey. — We appear to possess this species, which is 

 closely allied to S. ruficornis, in Britain. I have seen specimens from variotis 

 localities ranging from the South of England (Lewes), to Scotland (Rannoch). 



*Sepsis biflexuosa, Strobl. — This dark-legged species has veiy distinct male 

 front tibiae, the dorsal sxxrface starts straight, but before the middle springs in 

 an arched line to the tip, the ventral surface after a short, slender knee portion, 

 forms a large swelling ending somewhat abruptly jvist beyond the middle of 

 the tibia, then extends in an almost straight line to the tip ; the swelling bears 

 short bristles about its middle. There is only one long bristle beneath the 

 front femora, very close to a large swelling bearing two moderately long bristles 

 and a number of very short ones. Three males were taken by Mr. Verrall in a 

 paddock behind his house (Newmarket, Suffolk) in August, 1894, and May, 1895. 



Sepsis duplicata, Hal., was probably described from an abnormal specimen 

 of S. violacea possessing an adventitious cross-vein to each wing. 



Sepsis maculipes, Wlk., and concinna, Wlk., are unrecognisable from the 

 descriptions, and had better disappear from the List. 



Ucnicita leachii, Mg. — I agree with Haliday (in Westwood's Generic 

 Synopsis, 1840, p. 148) that this species is better placed in Henicita tlian in 

 Themira ; in addition to the abdomen being subpetiolate, the great development 

 of the back of the head, the absence of the liumeral bristle, and the short 

 wings all point to its being congeneric with annulipes. Themira curvipes, v. d. 

 Widp, almost certainly belongs to the same genus. 



Themira nigricornis, Mg. — I have never seen a British specimen, and 

 Walker's description cannot refer to a species of Themira at all The name 

 has no right to remain in the List. 



Themira spinosa, Verr. — An examination of the type of Th. pusilla, Zett., 

 at Lrmd, convinced me that spinosa, Verr., is only a synonym of Zetterstodt's 

 species. 



Themira superha, Hal. — It should be noted that Th. pilosa, Wlk., (Ent. 

 Mag. i, 1833, p. 254) is a synonym of this species, but pilosa, Dsv., is a synonym 

 of putris, L. (v. Wlk. Ent. Mag. iii, 1836, p 182). Th. ciliata, Stseg., is also 

 a synonym of superha, Hal. 



Themira minor, Hal. — Th. dentimana,v. d. Widp (18G4), is a synonym of 

 this species in addition to lucida, Staeg., but minor, v. d. Wulp (1864) and 

 Schiner (1864) ^ consobrina, v. d. Widp (1871), v. Tijd. v. Ent., xiv, 191-192 

 (1871). 



Nemopoda tarsalis, Wlk., and J'umipennis, AVlk., are mere names in the List, 

 they shoidd share the fate of Sepsis ynacidipes and concinna. 



Snltella nigripes, Desv. — This may be only a variety of scutellaris, I have 

 not siiflicient material to decide. S. basalis, Hal., was quoted as a synonym of 

 nigripes by Walker.
