When the larval and pupal F,G. 5. pelts have been placed in them they can be corked and :ed, or better, if so long as to permit of it, they can be drawn out in a small flame and sealed. Method of use. The stages collected in the field, and from which it is desired to breed adults, are placed in a dish of such a size as to render it easy to ensure the isolation of individuals, and one by one these axe transferred to the capsules, each into one capsule; this is filled with water and replaced in its position in the board, as evaporation occurs the fluid lost must be replaced daily to keep the water at the surface level. This is especially necessary in the case of anopheline larvae. The capsule is marked by a number written.
