Sapromyza quadrivittata, Lw., was recorded by Mr. Malloch from Bonhill 

 (Dumbarton) in this Magazine for 1908, p. 138. 



-*Saprovxyza nitidifrons, Becker, is allied to decipiens, Lw., but the frons is 

 shining- and the pubescence of the arista is longer ; it was taken by Col. Yerbury 

 at Porthcawl (Glamorgan) in May, 1906. 



Sapromyza pallida, Fln.-I have never seen a British specimen of this 

 species as interpreted by Becker (v. Sapromyza illota, p. 170). 



Sopror>^yza tarseUa, Zett., was phxced in the "List" in mistake for ohsoleta. 

 Fin. I have never seen a British specimen. 



Sapromyza apicalis, Lw.-Eecorded by Eev. Thornley in his List of 

 Lincolnshire Diptera (1899), and by Eev. W. J. Wingate in his List of Durham 

 Diptera 1906. I have never seen a British specimen. 



Sa'prcvyza placida, Mg.-This species has very slight claims to remain in 

 the List, it was recorded by Curtis in 1837, though it was unknown to him, and 

 no one appears to have recognised it since it was described. 



Paralan.ania albiceps, Fln.-Mr. Malloch has confirmed the occurrence of 

 this species in Britain in this Magazine for 1909, p. 41. I have seen specimens 

 taken in Herefordshire by Dr. Wood, and in the New Forest by Mr. C. O. Lamb. 

 Cnemacantha muscaria, Fln.-Mr. Malloch has also recorded this species on 

 p. 234 of this Magazine for 1909. Mr. Verrall possesses a specimen taken by 

 Mr. Coryndon Matthews at Stoweford Cleave (Devonshire) on August 19th, 1888. 

 Peplomyza wiedemanni, Lw., is now considered a synonym of UUira, Mg., 

 under which name it should appear in the List. P. banmhaueri, Lw.^c^^sco^c^ea, 

 Mg., is a distinct species of which I have not seen a British specimen. 



" 'lanxania atrwtana, Mg., is an unrecognised species recorded by Stephens 

 (1829) in his Catalogue as having been taken by himself within 2.5 miles ot 

 St. Paul's Cathedral. 



Lauxania geniculata, Mg., has been recognised as a good species by Becker 

 (1902) Specimens taken by Mr. Verrall at Upware (Cambs.) on July 11th, 

 1875 and near Aberdeen on Jiuie 3rd, 1884, also by Col. Yerbxuy at Nairn m 

 Jtxne' 1900, may be at once separated from L. ^nea by having a much more 

 shining thorax (owing to the absence of pollen) and darker legs, but I am not 

 sure that they do not answer better to the description of L. nitens, Lw. 



Lauxania hyalinata, Mg.-L. frontalis, Lw., is a synonym of this species 

 (t Becker Zeitschr. Hym. Dipt., 1902, 232), and I feel sui-e that Haliday's L. a,mca 

 is'another synonym. It has been found by Dr. Wood in Herefordshire m June, 

 and I have seen it from the New Forest. Becker placed it in the genus 

 Sapromyza, but I consider that Loew was correct in considering it a true 

 Lauxania. 



LONCH.fflID.ffi. 



Lonchwa pusilla, Mg.-This is a synonym of Lauxania hyalinata, Mg., 

 according to Becker. 



Lonchsea lati/rons, Mg., is considered a synonym of lasiopUlialnia, Mg. I 

 have not seen a British specimen.
