The Entomologist's record and journal of variation . ng them to Dr. Sattler (British Museum, NaturalHistory), they were compared with the specimens of M suffusella inthe Museum and with the single example there of M appeared to conform to the latter, and examination of thegenitalia confirmed they were in fact this new species to the Britishfauna, and so were exhibited as M. niphognatha at the meeting ofthe British Entomological and Natural History Society on the12th July 1984. Having informed a friend, Mr. Norman Heal, of mygood fortune at Stodmarsh, he proceeded to the locality on the8th July, and there took a further two male niphognatha at liglit. A description of the imago follows: Alar expanse 12-13 whitish-ochreous. Forewings whitish-ochreous, becomingfuscous apically; discocellular stigma dark fuscous; subcostal oblongfuscous stigmata at 1/6 and 1/3; an indistinct, fuscous mid-plicalmark. Hindwings pale grey. NB. M. niphognatha lacks the charac-teristic costal spot present in M. suffusella (see figure 2).. Fig. nipl-iognatha, male genitalia The species was first described from Hungary (Gozmany, 1953),since when it has been found in Sweden (Svensson, 1980) andDenmark - dates of capture, 27th June 1981, 18th June to 9thJuly 1982 (Buhl et al., 1981). The early stages are apparentlyunknown and its foodplant has yet to be discovered. However,in an interesting communication to me, Mr. I. Svensson (1984)writes: ^Monochroa niphognatha seems to have had a good year in1984, or possibly it is because of increased collecting in suitablelocalities. It was discovered in two more Swedish provinces: Blekingeand Oland. Most specimens were collected coming to mercury lamps. 22 ENTOMOLOGISTS RECORD, but in 1983 I swept two worn specimens on , probably also thelatest date in Sweden. The localities are always moist meadows withscattered Salix, some Carex, Lysimachia vulgaris and Polygonum,probably amphibium. Most Swedish co
