AbstractThis paper reviews recent work on the higher systematics of insects and summarizes the various phylogenetic concepts advocated. It is evident that there is considerable difference of opinion. This is likely to prevail since the fossil record is inadequate. It is suggested that a numerical analysis of the insects at the Order level might be profitable.

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.
