and conspicuous dorsal bristles, antero-dorsal surface fringed throughout with short 

 regularly- disposed bristles, and with three long and conspicuous ones in apical half, 

 antero-ventral surface with a row of six to eight regularly disposed bristles of 

 moderate length in apical two-thirds, postero-ventral surface with a characteristic 

 tuft of fine hairs in median third, these hairs gradually decreasing in length towards 

 apex. Wings with a slight yeUowish-hroton tinge, calgptra distinctly tinged toith 

 orange, halteres with black knob. Size, 6—7 mm. 



Female : Frons one-third of width of head, deep black, with a very slight 

 brownish-grey tomentum in certain lights, ocellar triangle polished black. Thorax 

 and abdomen uniformly shining fi/ac^", without tomentum. Front femora with eight 

 to nine postero-ventral bristles, of which those in apical half are about twice the 

 length of the rest. Middle tibiae as in $ ?. In the single female I iiave seen only 

 one middle leg is present, and the tibia has one posterior bristle at one-fourth from 

 apex, and two rather small antero-dorsal bristles in apical third. Hind femora with 

 antero-dorsal bristles as in (J , antero- ventral surface with only about four bristles 

 in apical third, ventral and postero-ventral surfaces only with short pubescence. 

 Sind tibise with dorsal bristles as in $ , three long antero-dorsal bristles, but no 

 fringe of short ones, and no bristles on the other surfaces. Wings hyaline, a little 

 yellowish at base, ca'yptra and halteres as in c? . 



This species was first introduced by me as British in the "Annals 

 of Scottish Natural History," 1904, pp. 158-160. In addition to the 

 four males there alluded to, I have seen a single female taken by Mr. 

 Carter at the same place and time (Aberfoyle, July 4th, 1903), and 

 also a male taken by Col. Terbury at Porthcawl, Glamorganshire, on 

 June 6th, 1903. I suspect that the species has hitherto been over- 

 looked, and it should occur in other localities, [most likely in hilly 

 districts. The female was previously unknown.

B. hicolorellum Zett. : I had only unsatisfactory specimens of 

 this species from Wicken Fen, and Plashet Wood near Lewes, until 

 Mr. C. G. Lamb took a male in perfect condition at Pad stow, in 

 Cornwall, in July, 1902, and he took it again in the New Forest, in 

 July, 1905. It is a very little known species up to the present time.
