82) is almost certainly B. canescens, as he omitted that comparatively common 

 British species, and said "black hairs ... on each side of the epistoma." 

 The other records probably also refer to B. canescens or possibly to B. minor, 

 as I have noted in the synonyraical note on p. 505. 



33 S. snlphureus Mikan has only got into the British list through Loew's (Neue 



Beitrage, ii., 37) mistake in believing that Walker's B. ctenopterus was a true 

 Systoechus, and instead of being S. ctenojyterus was the allied species *S'. 

 sxdphureus. 



34 Anastoechns nitid^ihis Fabr. was included in Curtis' Guide (Ed. ii.), 244, but as he 



himself admitted (Brit. Ent., 613) under a mistake. 



35 Bomhylius pictus Panz. Recorded by Stephens and Curtis, and repeated by 



Duncan (Mag. Zool. Bot., ii. 208) in 1838 on the authority of Stephens. 



36 B. medius L. Naturally recorded by all old authors in mistake for B. discolor. 



It differs from B. discolor in having no black pubescence about the end of the 

 abdomen, and is a possible British species. 



37 B. venosus Mikan. Walker in his List of Diptera, i., 284 (1849) included this as 



a synonym of B. minor; it is however much more closely allied to B. 

 canescens and (as it is common in Germany) may occur in Britain. Stephens 

 recorded it doubtfully in his Catalogue (1829). 



38 B. cruciatns Fabr. Stephens and Curtis included as British B. jMsticus Fabr. 



which is a synonym of B. cruciatus Fabr., in mistake probably for B. posticus 

 Meig. which is a synonym of B. fugax Wied. B. crnciaUis is a very distinct 

 South European species, 



39 B. fugax Wied. Stephens and Curtis included B, posticns Fabr. as British as 



mentioned under the previous species, but undoubtedly in mistake for B. 

 jMsticus Meig. which is a synonym of B. fugax Wied. I myself reintroduced 

 it as British from a specimen in the late Dr P. B. Mason's collection, but I am 

 now inclined to believe that that specimen was only a very large B. canescens, 

 as at that time I had no knowledge to what size B. canescens could extend. 

 The specimen was acquired by Dr Mason from Mr Benjamin Cooke, and was 

 probably taken by him in Lancashire. B. ftigax is not an unlikely species 

 to occur in Britain. 



40 B. cinerascens Mikan. Stephens,' Curtis, and Duncan all gave this species as 



British, but probably in mistake for B. canescens. I have however called 

 attention to a possible British specimen in my synonymical note under 

 B. minor (p. 505). 



41 Ploas virescens Fabr. Licluded by Stephens, and Duncan said (Mag. Zool. Bot., 



ii., 212, 1838) " Specimens in the British Museum are said to have occurred in 

 " this country." 



42 Lamatia Belzehul Fabr. Included by Stephens and Curtis ; Walker (Ins. Brit. 



Dipt., i., 79) said "Very rare ; has been found near Bristol ? (E.)." 



43 L. lateralis Meig. Also included by Stephens and Curtis ; Walker (I.e.) said 



"Very rare in Britain; has been found near Bristol? In the British 

 " Museum," and a specimen exists in the British Museum which bears a label 

 " Swansea " {t. Colonel Yerbury). A specimen exists in C. W. Dale's collection 

 at Oxford which is noted " Millard, Bristol," and in Dale's note-book is added 

 "Devon? Dr "Leach? in Brit. Mus." These persistent references are
