SAPBOMYZID^. 



26. Sapnnmjza leeAa, Zett. This species resembles rorida, but the 

 acrostichal bristles are distinctly placed in only two rows, and the 

 thorax is dull and the arista not so pubescent, moreover it is smaller 

 (o mm.). Col. Yerbury caui^ht a male at Nethy Bridge (Inverness), 

 July 30th, 1911, and two females at Loch Assynt (Sutherland), June 

 2nd and 6th, 1911. 



27. Saproimjza qaadruiofafa, Zett. The two pairs of spots on the 

 abdomen, yellow palpi, acrostichal bristles in four rows, and small size 

 (2| mm.) will serve to distinguish this species, of which Col. Yerbury 

 took a male at Lochinver (Sutherland) on July 7th, 1911. 



Sapromyza ajjicaiis. Lw. In this Magazine for 1910, p. 171, I 

 stated that I had never seen a British specimen of this species, but on 

 July 4th and 8th, 1912, 1 caught six males and three females at Frinton- 

 on-Sea (Essex). 



CHLOBOPIDJi]. 



28. Diplotoxa ruficeps, Zett. The thorax of this little species is 

 uniformly greyish black and unstriped (though the scutellum may show 

 signs of yellowish red) and the vertical triangle also gi-eyish black and 

 very large. Col. Yerljury caught a male at Loch Assynt (Sutherland) 

 on July 20th, 1911. 



GEOMYZID^. 



29. A'phaniosoma quadrinotatum, Becker. The genus Aphaniosoma 

 was fomided by Becker in his work on Egyptian Dipiera (1902), and 

 is closely allied to Chiroinyia {Pelethoplula of the "List"), while 

 A. quadrinotahim was described by Becker as a new species of Pelethu- 

 phila from the Canary Isles (1904). In July of the present year 

 (1912), Mr. C. G. Lamb sent me specimens which he had found in 

 June on the flowers of Matricaria growing near Padstow (Cornwall), 

 with the suggestion that they might belong to the genus Aphaniosoma. 

 The species may be known by the four greyish stripes and five pairs of 

 dorso-central bristles on its yellow thorax. Strobl has found it in 

 Spain, but his specimens appear to have the general pubescence of the 

 body of a whitish colour, while in British specimens it is dark. 



30. Aphaniosoma approximatum, Becker. When I received the 

 specimens of A. quadrinotahim from Mr. Lamb, I was collecting on the 

 Essex coast at Walton-on-Naze, and foiuid in the Convolvidus flowers 

 on the cliffs a species of the same genus which turned out to be Becker's
