Since the account (Chandler, 1987a) of additions to the groups dealt with by Hutson, Ackland & Kidd (1980) was compiled, 10 further species in these groups have been discovered in Britain, one of which (Macrocera nigropicea Lundstrom) has been published already (Chandler, 1990). The male of Mycomya insignis and female of M. britteni have been recognized in British material and a new name is necessary for Boletina brevicornis sensu Edwards. New records are provided for other uncommon species. BOLITOPHILIDAE Bolitophila nigrolineata Landrock, 1912 New to Britain. This runs to the hybrida Meig. and rossica Landrock couplet in the key by Hutson, Ackland & Kidd (1980). The venational character given to separate these two species is subject to variation in hybrida and the genital characters are best checked. The three species can, however, be roughly separated on thoracic coloration: grey dusted with darker grey stripes in rossica, grey to brown stripes on a lighter yellowish to brown ground in hybrida, but more sharply marked dark chocolate brown stripes on a thinly grey dusted yellowish ground in nigrolineata. The British material has wing length mm in the male, mm in the female. Male and female genitalia are shown in Figures 1-3. B. nigrolineata is recorded from Germany, eastern Europe and Japan. Material examined. Perthshire: Pass of Killiecrankie, , female; 1989, female; Rannoch, near Allt nan Bogair, , 2 males; Durham: Nesbitt Dene, , male (P. J. Chandler)..
