A new key to the suprageneric taxa in the Beetle Family Cetoniidae, with annotated lists of the known Genera Naturalis
Krikken, J..
A revised key to the subfamilies, tribes and subtribes of the Cetoniidae (Coleoptera: Scarabaeoidea) is presented. Comments are given on the classification implied by the key, which includes several redefinitions. All the known genera (ca. 510) are listed under their tribe or subtribe, the position of several being different from that in Schenkling's catalogues (1921, 1922). References to recent synoptic literature are given. Eighteen new subtribes are proposed, the majority in the tribe Cremastocheilini. One new tribe is proposed, the Platygeniini. Attention is drawn to various new and neglected synonymies, original spellings, and other nomenclatural matters regarding family-group and genus-group names. The position of many genera is briefly discussed....

A new Orthotyline Mirid (Heteroptera) from Syria Naturalis
Doesburg, P.H. van.
A new species, Zanchius stami Van Doesburg (Insecta, Heteroptera, Miridae, Orthotylinae) from Syria, Deir-ez-Zor, is described and illustrated. Late eggs taken from the female abdomen have a peculiar chorionic process. It was found living (predaciously?) on cotton plants. It is compared with the closely related Z. alatanus Hoberlandt, 1956. Type specimens are deposited in the Rijksmuseum van Natuurlijke Historie, Leiden, two paratypes in the Národní Muzeum, Praha.

The genus is characterized by small to minute shells, which are thin, sculptured with axial ribs and many spiral lirae. The protoconch is heterostrophic and immersed. Aperture with complete peristome.

A note on an interesting association of the crab Platypodiella picta (A. Milne-Edwards 1869) and species of Zoantharia Naturalis
Hartog, J.C. den; Holthuis, L.B..
In the framework of the CANCAP-Project, a long-term oceanographic collecting program performed by the Rijksmuseum van Natuurlijke Historie, extensive shore collections were made from 1976 onwards on most of the Macaronesian Islands. During the collecting trips, a very ornamental crab, Platypodi ella picta (A.MILNE EDWARDS, 1869) was found on three occasions by the senior author. In addition the species was collected on the coast of Senegal. In all cases it was found associated with species of Zoantharia.

A note on environmental aspects of penaeid shrimp biology and dynamics IRD
Garcia, Serge.
Shrimps are short-lived animals living in highly variable inshore areas during the juvenile phase and are therefore subject to particularly strong environmentally driven variability in recruitment and stock size. This paper examines the likely consequences of this fact on the surplus yield production and stock-recruitment modelling underlining the high risk of generating artefactual models when the data series are short.

A NOTE ON FORECASTING WITH ECONOMETRIC MODELS AgEcon
Allen, P. Geoffrey.
Forecasts made by econometricians are typically conditioned on actual values of explanatory variables, even when at the time of the forecast, such variables might not be available. As a first step, one might test the adequacy of econometric specification by comparing conditional post sample forecasts with those of a univariate ARIMA model. Second, when explanatory variables must themselves be forecast, those for which this can be done only badly, should be omitted from the final model. A better forecast will result. An example of screening out badly forecasted explanatory variables is presented.

A Note on the Use of a Logarithmic Time Trend AgEcon
Watts, Geof; Quiggin, John C..
It is shown that parameter estimates in a regression with a logarithmic time trend are not invariant to the choice of the starting point of that time trend. Possible solutions to this problem are discussed and applied to data from a recent article in this Review where a logarithmic time trend was included. It is suggested that the appropriate course is either to estimate the starting date directly or to adopt a functional form invariant to the choice of starting date.
