21. Dexiopsis rubricorriis, Zett. This little known species was 

 found by Col. Yerbuiy at Portlicawl in June, 1903, and July, 1906. 

 The face, frons, antennae, and abdomen are more extensively pale 

 coloured than in the most extreme form of litoralis, and the male 

 genii alia very different. Herr Stein, who has seen some of the 

 specimens, confirms the identification. 



22. Pegomyia ulmaria, Rdi. This species has yellow palpi, the 

 thoracal squamae somewhat larger than the alar, the scutellum grey like 

 the thorax and bare about the middle. I caught several in the shady 

 part of the garden here in July, 1911, but it has also occurred in May 

 and August. 



23. Pegomyia nigrisquama, Stein, is one of the darkest species of the 

 genus, having black palpi, darkened squamae, and very dark legs, only 

 the middle and hind tibiae being slightly reddish. I have seen a single 

 male taken by Mr. Harwood near Colchester in 1911.

24. Limosiria ceenosa, Rond. When I was at the South Kensington 

 Museum on February 7th, 1912, Mr. F. W. Edwards called my 

 attention to a species of Limosina received from Mr. G. Lees of 

 Oldham, Lancashire, who stated that they were " swarming in closets, 

 causing great inconvenience to inhabitants" early in November, 1911. 

 A critical examination revealed the fact that they represented, as 

 Mr. Edwards suspected, a species distmct from. fo7itinaI is, and could be 

 separated from that latter (which they resembled in having eight 

 bristles round the scutellum and no incurved bristles on the thorax) by 

 the much longer pubescence to the arista, the lurid red basal joints of 

 the antennae, and the difference in length between the penultimate and 

 last costal segments being as 11 : 8 compared with 13 : 7 of fontinalis . 

 in addition, the hypopygium of the male is more densely clothed with 

 longer hairs than in fontinalis. I find that the late Mr. Verrall took 

 a female in his brother's garden at Denmark Hill on February 28th, 

 1868, and a male at Plasliett, near Lewes, on March 24th, 1868, and I 

 caught a male in the garden here (Suffolk) on August loth, 1897. 



25. Limosina pullula, Zett. This small species has a reddish- 

 yellow face and legs, the cubital vein slightly curved and ending long 

 before wing tip, and the penultimate costal segment practically equal 

 in length to the last ; also the middle bristle of those incurved on 

 front of frons is much more developed than the others near it. I find 

 it at Chippenham Fen (Cambs.) in March and April.
