18a. B. spissirosfrls, Zett. : must at present be removed from 

 our Lists. The true B. sjylssirostris is a little known species of which 

 I have seen the types ; our species, which is common over brackish 

 water on the Eastern Coast, and which may extend inland (even up to 

 my own <.^arden), is probal>ly B. (Ussimilis, Zett., but I believe it has 

 two or three other synonyms such as perhaps parachjxa, Wahlgren, or 

 erberi, Mik. 



19. Pachymeria erberi, Now. : This well marked species was 

 described by Nowicki in 1864 (?) from Gralicia, Austria, and subse- 

 quently was found by Bezzi in Italy. It occurred in numbers in 

 Butley Decoy Wood in Suffolk on July 11th, 1908, where the males 

 were swinging to and fro in a sort of slow dance, and each one was 

 holding a large Muscid as its prey. Unfortunately its distinctness 

 from P. femorata was not noticed, and I only took three specimens, 

 one of which held Hijdrotma irritans, and the other two Polletiin ves- 

 pillo, all larger species than itself. I believe I possess specimens from 

 other British localities. 



20. Hilar a arronetha, Mik : I caught a number of this line 

 species near Leith Hill as long ago as June 25th, 1868, and suspected 

 then that they belonged to an undescribed species. I also took one 

 male at Tunbridge Wells on June 6th, 1886. It has since been 

 described from Styria and Hungary. I have paid close attention to 

 the British species of this genus during the last three or four years, 

 but I find them exceedingly difficult to name ; I can, however, intro- 

 duce a few with confidence, of which this is one. 



21. H. Iwjubris, Zett. : Col. Yerbury caught a male of this fine 

 species near Stanford, in Norfolk, on May 21st, 1909. 



22. H. diver sipes, Strobl : I am obliged to refer the Braemar 

 specimens, upon which I introduced K. nitidula to the British Lists, 

 to this species, but the true H. nitidula (according to Strobl), was 

 taken in numbers by Col. Yerbury at Nairn at the end of May, 1905, 

 and l>y nie at Chippenham near here abovit the middle of May, 1908. 

 I cannot, however, accept the nomenclature of Strobl' s paper without 

 considerable doubt ; the species, for instance, which he identities as 

 H. matrona, Hal., is not at present known in Britain, but the true 

 H. matrona is one of his forms of H. spiniinana, Zett. 



23. if. pubipes, Lw. : Easily distinguished by the dense and 

 fairly long bristly pubescence on the middle tibia3 and tarsi, by the 

 yellow halteres, by the four dark sharply detined thoracic stripes, and
