A cladistic analysis of the genus Melanophora Meigen, 1803 (type-species: Musca grossificationis Linnaeus, 1758 [= Musca roralis Linnaeus, 1758]) is presented and the generic delimitation is critically redefined. The nominal genusgroup taxon Bequaertiana Curran, 1929 (type-species: Bequaertiana argyriventris Curran, 1929) is synonymised with Melanophora Meigen syn. nov. The following new combin...

In 1998 Land Information New Zealand introduced New Zealand Geodetic Datum 2000 (NZGD2000) as its new national datum. It is defined as a semi-dynamic datum and incorporates a national deformation model to ensure that the accuracy of the datum is maintained. The deformation model allows observations made at an epoch other than the datum reference epoch of 2000.0 to be modeled so that coordinates...

The Japanese species of the sawfly genus Siobla Cameron, 1877, are revised and keyed. The following nine species are recognized: S. apicalis Takeuchi, 1929, S. ferox (Smith, 1874), S. hirasana Takeuchi, 1929, S. jucunda (Mocsáry, 1909), S. metallica Takeuchi, 1929, S. sturmii (Klug, 1817), S. japonica, sp. nov., S. pulchra, sp. nov., and S. takeuchii, sp. nov.  Siobla pacifica (Smith, 1874) is ...

The result of crossing two well-inbred lines of organisms for each of which there has been established by repeated test a characteristic relationship between some aspect of performance or behavior and a measured external condition governing the performance, is important in at least two respects. I t should contribute to the demonstration of the degree of reality inhering in the formulation used...
