The dry season is favourable on some moist biotopes. These small places seem to concentrate the insects from the dry environment. The sifting of materials from shores, from under logs, treebark or dung etc. gives particularily good yields. The shore washing and water collection is usually more successful in the dry season,in and around the shrunken water courses. It is obvious that not only the abundance of insects but also the aspect of the fauna is subject to seasonal changes. But in spite of many successful collectings in the dry season, I can remember only a few species which have not been collected in other seasons.A more precise evaluation of the seasonal changes can be provided only after the identification of the collected material. The applied collecting methods There is a recurrent question as to how an entomological mission in the tropics should be equipped. Though literature ÍB not particularily poor on this subject, everybody seems to learn only from his own failures on the first occasion. The main rule is, I think, that the equipment should be ^s simple as possible to-fulfill its task, without exaggerated adaptations to averseconditions. The metal parts should be of corrosion resistant material, and the sacks intended for frequent storing of moist material (inner sacks of Moczarsky-Winkler selector etc.) of nylon or similar cloth. On the other hand, the use of polythene bags is very limited and definitely not suitable for transportation of live material. Por this purpose, linen bags should be used. The nylon cloth, though drying quicker, appears to be too weak for grass nets and too light for beating nets. The use of nets in dripping vegetation is in any case very limited, and a heavy linen material is more suitable for this purpose. Although the equipment and methods applied are similar to those in the temperate zones, a short description of them will in-
