variable species, /S. JJavipes, and it is very probable that this is the true 



solution of the difficulty. S. nitidus of Meigen is (according to the 

 supposed type at Paris) only a small specimen of <S. iridatus. In August, 

 1908, I closely studied the Scandinavian type collections and saw 

 iS. nif/ripf-s and S. minimus of Zetterstedt, and found that I had misinter- 

 preted those species, N. mqripes being a member of the S.flavipes group 

 and in my opinion identical with my S. nitidus (nee Meigen), while S. 

 minimns may represent a composite species of which the Smol female and 

 the Wadstena male may be immature specimens of S. nuheculosns while 

 the Wadstena female may belong to another species, none of the speci- 

 mens appearing to be identical with ray S. minimus. The Scandinavian 

 representatives of S. rufipes mainly agreed exactly with the females as 

 understood by me and I still think that Wahlberg did not know the 

 male of his species ; other female specimens of (S. riifipes occurred under 

 labels of S. flavipes, or at least under " vars " of that species. iS. nitidus 

 Zett. belonged to a form near my interpretation, but is nearer the male 

 of S. flavlpi-s than that of S. ni</ripes. Fallen recognised the true male 

 of S. flavipes but probably mixed up S. rufipes with it. My S. minimus 

 (nee Zett.) still remains an unsatisfactory species. 



192. Microchrysa poUta was taken by Colonel Yerbury at Margam in Glamorgan 



on August 24, 1908. 



202. Beris vallata occurred at Ringwood as early as Maj' 28. 



247. 25. Omit the first "was." 



258, 48. The fourth figure should be 8, 



266. Leptis scolopncea. Colonel Yerbury caught this species at Port Talbot in 



Glamorgan on August 4, 1908. 



286. Fig. 189 should have been a reproduction of fig. I7l on page 242. 



316. Ptiolina atra. Mr James J. F. X. King has informed me that he and Mr 



Malloch took several specimens of this species on May 30, 1908, at 

 Bonhill. 



331, "I Hwmatopota crassicornis occurs on the East coast, a female having been 



340. J taken near Butley in Suffolk on June 28, 1908, at which time ii. italica 



could not be found. 



347. H. Bigoti. Two females were caught by Mr J. E. Collin amongst reeds in 



the Butley River near Chillesford Decoy in Suffolk 



on July 12, 1908, at a time when H. pluvialis was 



not uncommon, while I believe a female taken 



by Colonel Yerbury at Walton on-Naze on June 



11, 1908, and a female at Dartford in Kent on 



July 19, 1908, belong to this species. The eyes 



appear to have the bands different from the 



other species ; I give a figure (fig. 407) from one 



Fio. 407. of the females taken on July 12, 1908, and the 



following description has been drawn up from the other female taken 



on that day : 



Eyes with any pubescence hardly visible ; in life with four narrow 

 yellowish green bands (the uppermost one greenest, while the others are 

 nearly yellow) and five blackish purple bands which are broader than the 

 yellowish green bands ; the middle band broad and continuous though 

 narrowed to a rather narrow neck at the middle, but ending very broad 

 against both front and hind margins of the eye. All the bands (both 

 light and dark) run out entire to the hindmargin (but the upper and 

 lower green ones barely so), but the second and fourth dark bands widen
